General Power Tool Safety Warnings

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power too linun expected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce disrelated hazards.
Power tool use and car e
Do not force the power tool . Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety Rules for Rotary Tools

Safety warnings common for grinding, sanding, wire brushing, polishing, carving or abrasive cutting-off operations:
This power tool is intended to function as a grinder, sander, wire brush, polisher, carving or cut-off tool. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
The RATED SPEED of the accessories must be at least equal to the operating speed setting marked on the power tool.
Accessories running faster than their RATED SPEED can break and fly apart.
The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
The arbor size of wheels, sanding drums or any other accessory must properly fit the spindle or collet of the power tool.
Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
Mandrel mounted wheels, sanding drums, cutters or other accessories must be fully inserted into the collet or chuck. If the mandrel is insufficiently held and/or the overhang of the wheel is too long, the mounted wheel may become loose and be ejected at high velocity.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, sanding drum for cracks, tear or excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute.
Damaged accessories will normally break apart during this test time.
Wear personal protective equipment.
Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment.
Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Always hold the tool firmly in your hand(s) during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the tool to twist.
Use clamps to support workpiece whenever practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Clamping a small workpiece allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to bind or jump toward you.
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your control.
After changing the bits or making any adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
Do not operate the power tool near flammable materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Use only in well-ventilated area. Working in a safe environment reduces risk of injury.
Allow for sufficient space, at least 6”, between your hand and the spinning bit. Do not reach in the area of the spinning bit. The proximity of the spinning bit to your hand may not always be obvious.
Do not touch the bit or collet after use. After use the bit and collet are too hot to be touched by bare hands.
Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury.
This product is not intended for use as a dental drill, in human or veterinary medical applications. Serious injury may result.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kickout. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse  and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. The operator can control kickback forces, if proper precautions are taken.
Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.
Do not attach a toothed saw blade. Such blades create frequent kickback and loss of control.
Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed.
When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide cutters, always have the work securely clamped. These wheels will grab if they become slightly canted in the groove, and can kickback. When a cut-off wheel grabs, the wheel itself usually breaks. When a rotary file, high-speed cutter or tungsten carbide cutter grabs, it may jump from the groove and you could lose control of the tool.
Safety warnings specific for grinding and abrasive cutting-off operations:
Use only wheel types that are recommended for your power tool and only for recommended applications. For example: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange that are of correct size and length. Proper mandrels will reduce the possibility of breakage.
Do not ’’jam’’ a cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or snagging of the wheel in the cut and the possibility of kickback or wheel breakage.
Do not position your hand in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your hand, the possible kickback may propel the spinning wheel and the power tool directly at you.
When wheel is pinched, snagged or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in  motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the cause of wheel pinching or snagging.
Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
Use extra caution when making a ‘’pocket cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
Safety warnings specific for wire brushing operations:
Be aware that wire bristles are thrown by the brush even during ordinary operation.
Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin.
Allow brushes to run at operating speed for at least one minute before using them.
During this time no one is to stand in front or in line with the brush. Loose bristles or wires will be discharged during the run-in time.
Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be discharged at high velocity during the use of these brushes and may become imbedded in your skin.

Additional Safety Warnings

Do not use router bit with the Dremel chuck.
Bit may become a projectile and cause serious injury.
GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.
Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.
Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.
Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted.
Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Risk of injury to user. The power cord must only be serviced by a Dremel Service Facility.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Functional Description and Specifications

Disconnect the plug from the power source before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
Model 4300 High Speed Rotary Tool

Assembly

Always unplug Rotary Tool before changing accessories, changing collets or servicing your Rotary Tool.
LIGHT MODULE
The light module included with your tool is intended to provide you with improved visibility while working on your project. It uses 2 replaceable CR1025 batteries (included) to power the LED and can be rotated around the front of the tool depending on your needs.
Changing Batteries
Chemical Burn Hazard.
Keep batteries away from children. This product contains a lithium button/coin cell battery. If a new or used lithium button/coin cell battery is swallowed or enters the body, it can cause severe internal burns and can lead to death in as little as 2 hours. Always completely secure the battery compartment. If the battery compartment does not close securely, stop using the product, remove the batteries, and keep it away from children. If you think batteries might have been swallowed or placed inside any part of the body, seek immediate medical attention.
To change the batteries for the light module, begin by unscrewing the nose cap to remove the light module. Once it is removed, use a small screwdriver to loosen the screw on the battery compartment. De not pull the screw out completely! Remove the battery compartment housing from the underside of the module. Slide the old batteries out and replace with new batteries making sure to replicate the orientation of the original batteries. With the new batteries in place, replace the battery compartment housing and re-tighten the screw.
When reassembling make sure that the switch and the slider are both in the same ON (I) or OFF (O) position. This way the switch will match the “fork” of the slider (Fig. 2).
Installation and Use
To install the light module on the tool, begin by unscrewing the nose cap from the end of the tool. Slide the light module onto the end of the tool with the light pointing forward. Re-tighten the nose cap on the end of the tool to squeeze the light module ring in place (Fig. 1). The light module will only work with the new style nose cap that came with your tool. The difference between the old and new nose cap are shown in Fig. 2a.
Depending on how you are using your rotary tool, you may find that the light module is either in the way or that you would like to illuminate your workpiece differently. To reposition the light module, simply loosen the nose cap, rotate the light module as desired, and re-tighten the nose cap. DREMEL CHUCK
Dremel Chuck allows you to quickly and easily change accessories on Dremel Rotary Tools without changing collets. Accepts accessories with 1/32” – 1/8” shank. To loosen, first press shaft lock button and rotate the shaft by hand until the lock engages the shaft preventing further rotation.
Do not engage lock while the Rotary Tool is running.
With the shaft lock engaged use the wrench or the EZ Twist Nose Cap to loosen the chuck and open the jaws. Remove the accessory from the chuck. If necessary, continue loosening the chuck so that the new accessory fits between the jaws. Insert the new accessory into the chuck far enough so that there is approximately 1/4” between the end of the chuck and the beginning of the working part of the accessory (drill bit flutes, sand paper, engraving end, etc.). With the shaft lock engaged, tighten the chuck using the EZ Twist Nose Cap or wrench to secure the accessory.

Helpful Tips when using the
Dremel Chuck

• The Dremel Chuck and the collet and collet nut system are interchangeable on this tool.
  While the chuck will provide you with the best experience for changing accessories, the collet and collet nut will provide a more precise accessory holding solution especially in heavier side load applications. If you will be using your rotary tool for routing, heavy wood or metal cutting, heavy sanding, or carving you will probably have a better experience using the collet and collet nut.

• The Dremel Chuck needs to be securely tightened in order to retain the accessory during use. If you find the accessory slipping in the chuck, use the included EZTwist Nose Cap or wrench to tighten the chuck around the bit. If further slippage persists,  switch to using the collet and collet nut.

• The jaws of the chuck can become displaced if dropped, pried against, or filled with dust causing the accessory to no longer run true and concentric. This is often called run-out. To reset the jaws, apply the following procedure:

1. Remove the accessory from the chuck.
2. Clean the chuck if necessary using compressed air. Always wear safety goggles when cleaning tools with compressed air.
3. Press shaft lock button and tighten the chuck until the jaws extend past the outer surface of the chuck, approximately 1/8″.
4. Push the end of the chuck firmly against a hard flat surface to be sure the jaws are all seated axially.
5. Continue to hand tighten the chuck until the jaws completely close.
6. Loosen the chuck, and reinsert a straight accessory.
7. Tum the tool by hand and observe if there is any run-out. If there is obvious run-out, repeat the procedure.
8. With the shaft lock engaged, tighten the chuck using the EZ Twist Nose Cap or wrench to secure the accessory.
9. Tum the tool on to the lowest speed setting and observe for run-out. If there is obvious run-out, check that the accessory is straight before repeating the procedure.

BALANCING ACCESSORIES
For precision work, it is important that all accessories be in good balance (much the same as the tires on your automobile). To true up or balance an accessory, slightly loosen chuck or collet nut and give the accessory or collet a 1/4 turn. Retighten the chuck or collet nut and run the Rotary Tool. You should be able to tell by the sound and feel if your accessory is running in balance. Continue adjusting in this fashion until best balance is achieved. To maintain balance on abrasive wheel points, before each use, with the wheel point secured in the collet, turn on the Rotary Tool and run the 415 Dressing Stone lightly against the revolving wheel point. This removes high spots and trues up the wheel point for good balance.

4300 Attachment Compatibility
Dremel rotary tool attachments allow you to change the function of your tool so that it is more optimized for your application. You can find the full line of Dremel rotary tool attachments on Dremel.com. The Dremel 4300 is compatible with all currently available
Dremel attachments. Depending on the attachment being used, you will either need to use a collet and collet nut to hold the accessory or will be able to use the Dremel Chuck to hold the accessory. The following chart shows which attachments function with the Dremel Chuck. For more information on individual attachments, please refer to the user manual for those attachments in this manual or that came with those attachments.

Do not use router bit with the Dremel chuck. Bit may become a projectile and cause serious injury.

COLLETS
Four different size collets (see illustration), to accommodate different shank sizes, are avail- able for your Rotary Tool. To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the tool shaft. Replace collet nut on the shaft.
Always use the collet which matches the shank size of the accessory you plan to use. Never force a larger diameter shank into a collet.
Note: Most rotary tool kits do not include all four collets sizes.

COLLET IDENTIFICATION CHART
Collet sizes can be identified by the rings on the back end of collet.
1/32″ Collet has one (1) ring.
1/16″ Collet has two (2) rings.
3/32″ Collet has three (3) rings.
1/8″ Collet has no rings. (Included in most tool kits on the tool)

FIXING STUCK COLLETS
It is possible for a collet to get stuck within the collet nut especially if a collet nut is tightened on to the tool without abitinplace. If this happens, the collet can be removed from the collet nut by pushing the shank of an accessory into the hole in the collet nut. This should cause the collet to pop out of the collet nut.

COLLET NUT
To loosen, first press shaft lock button and rotate the shaft by hand until the lock engages the shaft preventing further rotation. Your
Dremel 4300 is equipped with a quick shaft lock mechanism. This mechanism engages the output shaft in 8 separate locations on the shaft for easier operation.
Do not engage lock while the Rotary Tool is running.
With the shaft lock engaged use the collet wrench to loosen the collet nut if necessary. The collet nut must be loosely threaded on when inserting an accessory. Change accessories by inserting the new one into the collet as far as possible to minimize runout and unbalance.
With the shaft lock engaged, use collet wrench or EZ Twist Nose Cap to securely tighten the collet nut. (Fig. 5). Avoid excessive tightening of the collet nut when there is no bit inserted.

EZ TWIST™ INTEGRATED WRENCH/NOSE CAP
The nose cap of your tool has an integrated wrench allowing you to loosen and tighten the collet nut without the use of the standard collet wrench. Unscrew the nose cap from the tool, line-up steel insert on inside of cap with collet nut. With the shaft lock engaged twist nose cap clockwise to tighten, and counter-clockwise to loosen (Fig. 6).

Operating Instructions

Dremel 4300
Thank you for purchasing the Dremel 4300.
This product was designed by the many Dremel users who passionately use their rotary tools daily. This tool was designed to give you the ultimate performance when working on projects.
The Dremel 4300 is the MOST versatile rotary tool available today. It has a wide speed range including a high performance motor with electronic feedback that allows the tool to maintain its speed under load. The design of the tool is symmetrical and contains plenty of soft grip so the tool can be held comfortably in many positions. The inclusion of the Dremel Chuck allows you to use any shank size accessory from 1/32” to 1/8” so that you don’t have to change collets when you change to a different size accessory. In addition, the included work light will help you see every detail as you work on your project. You will appreciate the many applications that the Dremel 4300 can easily tackle.
Rotary Tool Introduction
The Rotary Tool has a small, powerful electric universal motor, is comfortable in the hand, and is made to accept a large variety of accessories including abrasive wheels, drill bits, wire brushes, polishing accessories, engraving cutters, router bits, cutting wheels and attachments. Accessories come in a variety of shapes and permit you to do a number of different jobs. As you become familiar with the range of accessories and their uses, you will learn just how versatile the Rotary Tool is. You’ll see dozens of uses you hadn’t thought of before.
The real secret of the Rotary Tool is its speed.
To understand the advantages of its high speed, you have to know that the standard portable electric drill runs at speeds up to 2,800 revolutions per minute. The Rotary Tool operates at speeds up to 35,000 revolutions per minute. The typical electric drill is a low-speed, high torque tool; the Rotary Tool is just the opposite — a high-speed, low torque tool.
The major difference to the user is that in the high speed tools, the speed combined with the accessory mounted in the chuck or collet does the work. You don’t apply pressure to the tool, but simply hold and guide it. In the low speed tools, you not only guide the tool, but also apply pressure to it, as you do, for example, when drilling a hole.
It is this high speed, along with its compact size and wide variety of special accessories and attachments, that makes the Rotary Tool different from other tools. The speed enables it to do jobs low speed tools cannot do, such as cutting hardened steel, engraving  glass, etc.
Getting the most out of your Rotary Tool is a matter of learning how to let this speed work for you. To learn about more uses and the versatility of Dremel accessories and attachments refer to this Owner’s Manual or check our website at www.Dremel.com or join
the conversation at facebook.com/dremel.
Using the Rotary Tool
The first step in learning to use the Rotary Tool is to get the “feel” of it. Hold it in your hand and feel its weight and balance. Feel the taper of the housing. This taper permits the Rotary Tool to be grasped much like a pen or pencil (Fig. 7).
Always hold the tool away from your face.
Accessories can be damaged during handling, and can fly apart as they come up to speed. This is not common, but it does happen.
Whenever you hold the tool, be careful not to cover the air vents with your hand. This blocks the air flow and causes the motor to overheat.
Practice on scrap materials first to see how the Rotary Tool’s high speed action performs. Keep in mind that the work is done by the speed of the tool and by the accessory in the collet. You should not lean on or push the tool during use.
Instead, lower the spinning accessory lightly to the work and allow it to touch the point at which you want cutting (or sanding or etching, etc.) to begin. Concentrate on guiding the tool over the work using very little pressure from your hand.
Allow the accessory to do the work.
For best control in close or detailed work, grip the Rotary Tool like a pencil between your thumb and forefinger (Fig. 7).
The “Golf Grip” method of holding the tool is used for more aggressive operations such as grinding a flat surface or using cutoff wheels (Fig. 8).
Usually, it is best to make a series of passes with the tool rather than attempt to do all the work in one pass. To make a cut, for example, pass the tool back and forth over the work, much as you would a small paint brush. Cut a little material on each pass until you reach the desired depth. For most work, the gentle touch is best. With it, you have the best control, are less likely to make errors, and will get the most efficient work out of the accessory. TOOL HANGER
The hanger is provided for the use of hanging your tool while using the Flex Shaft or for storage. If you do not use the hanger, snap it back into place so it will be out of the way while the tool is in use (Fig. 1).

Operating Speeds

To select the right speed for each job, use a practice piece of material.
NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool.
SLIDE “ON/OFF” SWITCH
The tool is switched “ON” by the slide switch located on the topside of the motor housing.
TO TURN THE TOOL “ON”, slide the switch button forward.
TO TURN THE TOOL “OFF”, slide the switch button backward.
HIGH PERFORMANCE MOTOR
Your tool is equipped with a high performance rotary tool motor. This motor expands the versatility of the rotary tool by driving additional attachments such as the Dremel Right Angle Attachment and Dremel Flex Shaft.
ELECTRONIC FEEDBACK
Your tool is equipped with an internal electronic feedback system that provides a “soft start”, which will reduce the stresses that occur from a high torque start. The system also helps to keep the preselected speed virtually constant between no-load and load conditions.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed dial. The speed may be adjusted during operation by presetting the dial on or between any one of the settings.
You can refer to the charts on pages 27-30 to determine the proper speed, based on the material being worked and the type of accessory being used. These charts enable you to select both the correct accessory and the optimum speed at aglance.
The speed of Rotary Tool is controlled by setting this dial on the housing (Fig. 9).

Settings for Approximate Revolutions.

• Wire Brush Setting.

Needs for Slower Speeds
Certain materials, however, (some plastics and precious metals, for example) require a relatively slow speed because at high speed the friction of the accessory generates heat and may cause damage to the material.
Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing accessories. They may also be best for working on delicate projects as “eggery” work, delicate wood carving and fragile model parts. (All brushing applications require lower speeds to avoid wire discharge from the holder.)
Higher speeds are better for carving, cutting, routing, shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals and glass require high speed operation, and drilling should also be done at high speeds.
The point to remember is this: Many applications and accessories in our line will provide the best performance at full speed, but for certain materials, applications, and accessories, you need slower speeds, which is the reason our variable speed models are available.
To aid you in determining the optimum operational speed for different materials and different accessories, we have constructed a series of tables that appear on pages 27-30.
By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar with them.
Ultimately, the best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what happens as you make a pass or two at different speeds.
When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then reduce the speed slightly to get the optimum working speed.
Some rules of thumb in regard to speed:

1. Plastic and other materials that melt at low temperatures should be cut at low speeds.
2. Polishing, buffing and cleaning with any type of bristle brush must be done at speeds not greater than 15,000 RPM to prevent damage to the brush.
3. Wood should be cut at high speed.
4. lron or steel should be cut at high speed. If a high speed steel cutter starts to chatter this normally means it is running too slow.
5. Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.

Increasing the pressure on the tool is not the answer when it is not performing as you think it should. Perhaps you should be using a different accessory, and perhaps an adjustment in speed would solve the problem.
Leaning on the tool does not help.
Let speed do the work!
Use only Dremel®, high-performance accessories. 

Maintenance Information

Service
Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Dremel Service Facility.
To avoid injury from unexpected starting or electrical shock, always remove plug from wall outlet before performing service or cleaning.

CARBON BRUSHES
The brushes and commutator in your tool have been engineered for many hours of dependable service.
In order to prepare your brushes for use, run your tool at full speed for 5 minutes under no load. This will properly “seat” your brushes, which extends the life of both your brushes and your tool.
To maintain peak efficiency of the motor, we recommend every 40 – 50 hours the brushes be examined. Only genuine Dremel replacement brushes specially designed for your tool should be used.

MAINTENANCE OF REPLACEABLE BRUSHES ON MODEL 4300
The brushes should be inspected frequently when tools are used continuously. If your tool runs sporadically, loses power, makes unusual noises or runs at a reduced speed, check the brushes.
To continue using the tool in this condition will permanently damage your tool.
Follow these steps to check/change the rotary tool brushes:

1. With the power cord unplugged, place the tool on a clean surface. Use the tool wrench as a screwdriver to remove the brush caps in a counter-clockwise direction (Fig. 10).

2. Remove the brushes from the tool by pulling on the spring that is attached to the carbon brush. If the brush is less than 1/8″ long and the end surface of the brush that contacts the commutator is rough and/or pitted, they should be replaced. Check both  brushes (Fig. 11).
   Usually the brushes will not wear out simultaneously. If one brush is worn out, replace both brushes. Make sure the brushes are installed as illustrated. The curved surface of the brush must match the curvature of the commutator. Also check that the brush caps sit flush with the tool housing.

3. After replacing brushes the tool should be run at no-load; place it on a clean surface and run it freely at full speed for 5 minutes before loading (or using) the tool. This will allow the brushes to “seat” properly and will give you more hours of life from each set of brushes. This will also extend the total life of your tool since the commutator surface will “wear” longer.

BEARINGS
Model 4300 has ball bearing construction.
Under normal use no additional lubrication is required.
Cleaning
To avoid accidents always disconnect the tool from the power supply before cleaning or performing any maintenance.
The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings. Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlo rinated cleaning solvents, ammonia and household detergents that contain ammonia.

Extension Cords

  If an extension cord is necessary, a cord with adequate size conductors that is capable of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3-wire extension cords that have 3-prong plugs and receptacles.
NOTE: The smaller the gauge number, the higher the cord capacity.

RECOMMENDED SIZES OF EXTENSION CORDS 120 VOLT ALTERNATING CURRENT TOOLS

Dremel Accessories

Use only Dremel®, high-performance accessories. Other accessories are not designed for this tool and may lead to personal injury or property damage.
Store accessories in a dry and temperate environment to avoid corrosion and deterioration.
The number and variety of accessories for the Rotary Tool are almost limitless. There is a category suited to almost any job you might have to do and a variety of sizes and shapes within each category which enables you to get the perfect accessory for every need.

COLLETS
If you expect to use a variety of accessories, we recommend that in the beginning you purchase a complete set of four collets. Store these so that you will have the proper size of collet for any accessory or drill bit you want to use. Currently, the 1/8″, 3/32″,1/32″ and 1/16″ collets accommodate all of the available Dremel accessories. 1/8″ collets are included in most rotary tool kits.
MANDRELS
A mandrel is a shank with a threaded or screw head, which are required when you use polishing accessories, cutting wheels, sanding discs, and polishing points. The reason mandrels are used is that sanding discs, cutting wheels and similar accessories must be  replaced frequently. The mandrel is a permanent shank, allowing you to replace only the worn head when necessary, thus saving the expense of replacing the shaft each time. Screw Mandrel No 401
This is a screw mandrel used with the felt polishing tip and felt polishing wheels. 1/8″ shank. Small Screw Mandrel No 402

Three different shapes of wire brushes are available. The three shapes come in three different materials: stainless steel, brass and carbon wire. The stainless steel perform well on pewter, aluminum, stainless steel, and other metals, without leaving “after-rust”.
Brass brushes are non sparking, and softer than steel; making them good for use on soft metal like gold, cooper and brass. The carbon wire brushes are good for general purpose cleaning.

Bristle Brushes
These are excellent cleaning tools on silverware, jewelry and antiques. The three shapes make it possible to get into tight corners and other difficult places. Bristle brushes can be used with polishing compound for faster cleaning or polishing.

INCORRECT:
Excessive pressure can cause wire breakage.

|
CORRECT: Wire tips doing the work.
|

Brushing Pressure

1. Remember, the tips of a wire brush do the work. Operate the brush with the lightest pressure so only the tips of the wire come in contact with the work.
2. If heavier pressures are used, the wires will be overstressed, resulting in a wiping action; and if this is continued, the life of the brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way that as much of the brush face as possible is in full contact with the work. Applying the side or edge of the brush to the work will result in wire breakage and shortened brush life.

Replacing Screw Mandrel Accessories

Mandrel No. 401 is used with the felt polishing tip and wheels. Thread the tip on to the screw carefully. The felt tip must thread down straight on the screw Mandrel, and be turned all the way to the collar.

Mandrel N° 402 has a small screw at its tip, and is used with emery cutting wheels and sanding discs. Higher speeds, usually maximum, are best for most work, including cutting steel. Which is shown here.

To replace a band on the Drum Sander, loosen the screw without removing it to contract the drum then slide the old band off. Slide the new sanding band on and then expand the drum by tightening the screw once again.

Before each use, check to make certain that all components are assembled to accessory shank and that the drum is sufficiently expanded to secure the band during use. If sanding band is loose on the drum during operation it may “fly” off and strike you or bystanders.

EZ Lock™ Operating Instructions

EZ Lock™ Mandrel No. EZ402 has a spring loaded sleeve and is used with cutting wheels, abrasive buffs and polishing cloth.

Always make sure the rotary tool is “OFF” and disconnect the plug from the power source or the battery pack from the tool before changing accessories. Such preventative safety measures reduce the risk of starting the power tool accidentally.
Always make sure accessory is properly seated on mandrel before use. Incorrect seating of accessory on mandrel may lead to personal injury or property damage.
To load accessory:

1. Place EZ Lock™ mandrel into collet as deep as possible and tighten collet nut. Note: There is a blue spacer that will bottom out on the collet nut, setting the mandrel to the correct depth. When using with Dremel chuck, back the mandrel out slightly before tightening.

Do not operate the flexible shaft with a sharp or multiple bends. Ensure that there are no sharp residual bends or kinks in the flexible shaft before operation. Over bending the shaft can generate excessive heat on the jacket or hand piece and may cause the flexible shaft to disengage from tool. The minimum recommended bend radius is 6”.

Always hold the hand piece firmly in your hands during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the shaft to twist.
Not for use with router bits or other large diameter (1” or larger) bits. Large diameter bits can cause kickback and loss of control when used with the flexible shaft.
Do not remove end ferrule while tool is running. The cable will become loose from the jacket and will uncontrollably whip or lash around.
Installation Instructions
It is extremely important to carefully read and follow the directions to assemble the flexible shaft to your rotary tool below to ensure the tool will function properly.
To properly attach the Flex Shaft to the rotary tool, THREE items must be removed from the tool: the nose cap, Dremel Chuck or collet nut and collet.

1. Press the Shaft lock button 1, unscrew and remove the collet nut or Dremel Chuck 2 (Fig. A1).

2. Unscrew the nose cap 3 from the tool (Fig. A2).

3. Remove the collet 4 (Fig. A3).
   Note: If the collet nut and collet are not removed from the motor shaft, the tool will not function properly.

4. Install the driver cap 5 on the motor shaft 6 and tighten (Fig. A4).
   To prevent damage to tool, do not overtighten driver cap. Tighten the driver cap finger tight and then tighten an additional 1/3 turn with the wrench or nose cap. (Wrench included with your rotary tool kit)

5. Attach by screwing the collar of the Flex Shaft 7 to the rotary tool. Make sure the square end of the center core engages the square hole socket in the driver cap (Fig. A5).

6. Refer to “Dremel Chuck” and “Collets” sections of the rotary tool manual for instructions on how to change accessories.

Do not pull out center core to engage into driver cap. This could cause disengagement of center core from handpiece. If tool stops when shaft is bent, center core may be lodged in driver cap. Loosen shaft and remove core from driver cap. Then screw flexible shaft onto rotary tool housing again.
Operating Instructions
Run-In before Operation
For optimum performance, allow your new flex shaft attachment to run at high speed on your rotary tool in a vertical position for 2 minutes before use (Fig. A7).
Disengagement of the Flex Shaft
The flexible shaft may become disengaged if the motor of your rotary tool is not elevated higher than the working end of the Flex Shaft.
Collet Removal and Replacement
Four different size collets to accommodate different shank sizes, are sold separately for your Flex Shaft. To install a different collet, remove the collet nut 2 and remove the old collet 4. Insert the unslotted end of the collet in the hole in the end of the Flex Shaft 8. Replace collet nut on the shaft (Fig. A5).
Flexible Shaft Lubrication
The Flex Shaft should be lubricated after every 25-30 hours of use. To lubricate, unscrew the Flex Shaft assembly from the motor housing. Pull the center core out of the Flex Shaft assembly. Wipe a very thin film automotive wheel bearing grease on to the center core and reinsert it back into the shaft. To prevent damage to tool do not over grease shaft. Too much grease will cause the unit to overheat.
Reattach the Flex Shaft to the rotary tool.

Cutting Guide attachment Models 565 and 566

Read the tool manual and these instructions for the use of this accessory with your tool. Failure to follow all instructions listed below may result in serious personal injury.
Do not use Dremel chuck with this attachment. Only use a collet and collet nut.
The cutting guide comes completely assembled and ready to use on a variety of materials up to 3/4″ (19 mm) thick. Always hold the tool firmly, using a slow steady pressure to guide the tool through your work. The speed of the tool will do the work.
IMPORTANT: Always cut in clockwise direction except when following a template , then cut in counter clockwise direction.

Cutting Guide Attachment Installation Instruction

1. Press the Shaft lock button 1, unscrew and remove the collet nut 2 (Fig. B1).

2. Unscrew the nose cap 3 from the tool (Fig. B2).

3. Place the collet nut 2 loosely on the end of the rotary tool and insert the cutting bit 4. Tighten collet nut 2 using the wrench or nose cap (Fig. B3).
   When inserting the #560, #561 and #562 Cutting Bit into your Dremel Rotary Tool, be sure that the bit is securely inserted into the collet. Always use the wrench or nose cap to tighten the collet nut to prevent the bit from loosening within the collet.

4. Thread the Cutting Guide Attachment 5 onto the exposed housing threads on the rotary tool (Fig. B4).

5. Adjust the attachment to the desired cutting depth (Fig. B5).

Drywall Cutting Bit – For use in drywall.
Use with 1/8″ (3.2 mm) collet #480 and collet nut.
When inserting the #560 bit into your rotary tool, it is very important that at least 1/16” (1.6 mm) and no more than 1/8″ (3.2 mm) of smooth shank remains visible above the collet.
Leaving too much shank out of the tool can cause the bit to spin unevenly and make the tool difficult to control. The guide has a “0” depth marking on it, however, when inserted properly, the bit will stick out from the end of the guide by 1/16” (1.6 mm) – 1/8″ (3.2 mm). The depth can be adjusted from that point on a continuous slide up to 3/4″ (19 mm).
When making freehand cuts in drywall – e. g. Repairing a hole in drywall, you may use the #560 Drywall Cutting Bit (cutting in a counter clockwise direction) or the #561 Multipurpose Cutting Bit (cutting in a clockwise direction).
When using a template (like an outlet box) behind the drywall, use the drywall bit #560, cutting in a counter clockwise direction. When using the #560 bit you will be able to cut in a counter clockwise direction because the bit has a piloted tip and won’t cut into the outlet box. The maximum cutting depth is 3/4″ (19 mm). Thicker materials may require a slower, steadier cut. The recommended tool speed for the Drywall Cutting bit is generally 25,000- 35,000 rpm. Caution should be used when making overhead cuts so debris is not getting drawn into the tool.

Multipurpose Cutting Bit – For use in wood, plastics, drywall, fiberglass, vinyl or aluminum siding, acoustical tile and laminates.
Use with 1/8″ (3.2 mm) collet #480 and collet nut.
When inserting the #561 bit into your rotary tool, it is very important that at least 1/16” (1.6 mm) and no more than 1/8″ (3.2 mm) of smooth shank remains visible above the collet. Leaving too much shank out of the tool can cause the bit to spin unevenly and make the tool difficult to control. The guide has a “0” depth marking on it, however, when inserted properly, the bit will stick out from the end of the guide by 1/16” (1.6 mm) – 1/8″ (3.2 mm). The depth can be adjusted from that point on a continuous slide up to 3/4″ (19 mm).
When making freehand cuts in drywall –ex. repairing a hole in drywall, use the multipurpose bit #561, cutting in clockwise direction. When using a template (like an outlet box) behind the drywall, use the drywall bit #560, cutting in a counter-clockwise direction.
The maximum cutting depth is 3/4″ (19 mm). Thicker materials may require a slower, steadier cut.
When plunge-cutting using the #561 Multipurpose Cutting Bit, start the bit into the material at a 45 degree angle and then slowly bring the bit and tool to a 90 degree angle to begin cutting. Keep in mind the sides of the bit are what actually do the cutting. Caution should be used when making overhead cuts so debris is not getting drawn into the tool.
Recommended tool speeds:
Plastics, Fiberglass
and Laminates . . . . . . . . . . . .10,000 – 15,000
Wood . . . . . . . . . . . . . . . . . . .20,000 – 35,000
Drywall, Vinyl or Aluminum

   Lawn Mower and Garden Tool Sharpener Operation

Consult your lawn mower owner’s manual for blade maintenance, blade removal, and reinstallation instructions. Cracks in blade body or improper blade removal and reinstallation may lead to serious injury.
Inspect the blade for cracks or missing sections. Replace blade if found cracked or damaged. Cracked or damaged blades can break apart under operation.
Wear eye protection, gloves, and a dust mask. The operation of any power tool can result in foreign objects being thrown into the eyes which can result in eye damage. Lawn mower blades have sharp edges which can lacerate hands. Grinding operations generate particles which can be inhaled.

Sharpen Blade
Place removed blade into a vise or clamp. Position sharpener attachment over the beveled edge of the blade, keeping at the angle of the guide following the angle of the existing beveled edge. Turn on rotary tool and pass over each end of the blade an equal number of times, at the same speed and pressure to keep the blade in balance until edge is sharp.
Stone grabbing on the blade corner can kick back and cause loss of control.
Balance Blade
Drive a nail into a beam or wall. Leave about one inch of straight nail exposed. Place the center hole of the blade over the head of the nail with the blade in a horizontal position. If the blade is balanced, it should remain in a horizontal position. If one side of the blade moves downward, use the grinding stone (without the guide) to remove small amounts of material from the very end of that side of the blade. Remove just enough material from the end to bring the blade to a balanced stop on the nail.
Sharpening other Garden Tools
The sharpener attachment may be used to sharpen other non-motorized lawn and garden tools such as shovels, hoes and pruning shears that will fit in the guide. Position sharpener attachment over beveled edge of tool to be sharpened. Following the angle of the existing beveled edge with the angle of the guide, pass over the edge of the garden tool at an even speed and pressure until it’s sharp.
