GENERAL POWER TOOL SAFETY RULES

Warning:

• Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
• People with electronic devices, such as pacemakers, should consult their physician(s) before using this product. Operation of electrical equipment in close proximity to a heart pacemaker could cause interference or failure of the pacemaker.

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 the 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 the 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. The use of a 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, nonskid 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 y our 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 tool in unexpected 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 dust-related hazards.

POWER TOOL USE AND CARE

• 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.

  • Do not over-tighten the wheel nut.
  • Use only flanges furnished with this grinder.

• Always inspect grinding wheels prior to use for cracks, missing pieces, etc. Replace the wheel immediately before use. USE ONLY GRINDING WHEELS that comply with ANSI B7.1 and are rated greater than 3450 RPM.
  GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces. For example pipes, radiators, ranges, and refrigerator enclosures.

• DO NOT use wheels with incorrect-size holes. NEVER use wheel washers or wheel screws that are defective or incorrect, and NEVER touch a grinding wheel or other moving parts.

• NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the g_rinding path of the wheel. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your hand to move into the wheel. ALWAYS make sure you have a good balance.

• NEVER stand or have any part of your body in line with the path of the wheel. DO NOT USE THE TOOL IF THE SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches been replaced by an authorized service center?

• DO NOT TURN THE MOTOR SWITCH ON AND OFF RAPIDLY. This could cause the wheel to loosen and create a hazard. Should this ever occur, stand clear and allow the wheel to come to a complete stop. Disconnect your grinder from the power supply and retighten the wheel nut securely.

• RISK OF INJURY DUE TO ACCIDENTAL STARTING. Do not use in an area where children may be present.

• NEVER START THE GRINDER when the wheel is in contact with the workpiece. SECURE WORK. Always hold the workpiece firmly against the work rest.

• DO NOT USE THE BENCH GRINDER if the flange nut or clamp nut is missing or if the spindle shaft is bent.

• FREQUENTLY clean grinding dust from beneath the grinder.

• DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY MEDICATION.

• ALWAYS STAY ALERT. Do not allow familiarity (gained from frequent use of your grinder) to cause a careless mistake. ALWAYS REMEMBER that a careless fraction of a second is sufficient to inflict severe injury.

• STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do not operate the tool when you are tired. Do not rush.

• SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct other users. If you loan someone this tool, loan them these instructions also.

• • ALWAYS EASE THE WORKPIECE AGAINST THE ABRASIVE WHEEL when starting to grind. A harsh impact can break the wheel. Use light pressure when starting to grind. Too much pressure on a cold wheel can cause the wheel to crack.

• USE ONLY FLANGES furnished with this bench grinder.

• IF ANY PART OF THIS GRINDER IS MISSING or should break, bend, fail in any way, or should any electrical component fail to perform properly, shut off the power switch, remove the machine plug from the power surce and have damaged, missing, or failed parts replaced before resuming operation.

• SAFETY SHIELD AND SPARK DEFLECTOR. The safety shields and spark deflectors are adjustable for operator convenience. Operating the grinder without these features attached could result in serious injury. Do not grind with the safety shield raised. Always wear safety glasses for personal protection.

• WORK REST. The work rests are independently adjustable to compensate for wheel wear. Before grinding, make certain the work rests are adjusted properly. Generally, the object being ground is done slightly above the center of the grinding wheel.

• Lawn mower blades are usually sharpened on only one edge and dressed up slightly on the other. Perform this sharpening process on both cutting ends of the blade. After sharpening, balance the blade by removing additional material.

Warning:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California 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.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote the absorption of harmful chemicals.

Warning:
Use of this tool can generate and/or disperse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA-approved respiratory protection appropriate for dust exposure. Direct particles away from face and body.

• Wear appropriate hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.

Warning:
ALWAYS use safety glasses. Everyday eye glasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CPA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA respiratory protection.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS

Warning:
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Use a separate electrical circuit for your tool. Your grinder is wired at the factory for 120 V operation. Connect to a 120 V, 3 Amp circuit and use a
3 Amp time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn, cut, or damaged in any way, have it replaced immediately.

GROUNDING INSTRUCTIONS

Warning:
This tool must be grounded while in use to protect the operator from electrical shock.

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides a path of least resistance for electric currents and reduces the risk of electric shock. This tool is equipped with an electrical cord that has an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching receptacle that is properly installed and grounded in accordance with all local codes and ordinances.

DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician?

IMPROPER CONNECTION of the equipment grounding conductor can result in a risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electrical cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

CHECK with a qualified electrician or service person if you do not completely understand the grounding instructions, or if you are not certain the tool is properly grounded.

USE only 3-wire extension cords that have three-pronged grounding plugs with three-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cords immediately. Use a separate electrical circuit for your tool. This circuit must not be less than #18 wire and should be protected with a 3 Amp time lag fuse. Before connecting the motor to the power line, make sure the switch is in the off position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

GUIDELINES FOR EXTENSION CORDS
USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Use an extension cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power, overheating and burning out of the motor. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified technician before using it. Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

Warning:
This tool is for indoor use only. Do not expose to rain or use in damp locations.

This tool is intended for use on a circuit that has a receptacle like the one illustrated in Fig. 1. Fig. 1 shows a three­pronged electrical plug and receptacle that has a grounding conductor. If a properly grounded receptacle is not available, an adapter (Fig. 2) can be used to temporarily connect this plug to a two­contact grounded receptacle. The adapter (Fig. 2) has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box.

Caution:
In all cases, make certain the receptacle is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

OPERATING INSTRUCTIONS

STARTING AND STOPPING THE GRINDER (FIGURE J)

Warning:
To avoid injury, always keep the plug disconnected from the power source and switch turned OFF until the sander is completely assembled and adjusted properly.

• The ON/OFF switch (1) is located on the front of the grinder. To turn the grinder on, press the switch to the “ON” position. To turn the grinder off, press the switch to the “OFF” position.

GENERAL OPERATION

Warning:
Keep all bystanders a safe distance away from the tool and not in direct line, front or back of the grinder.

• Your bench grinder has a medium wheel (60 grit) for medium material removal and general-purpose grinding, and a coarse wheel (36 grit) for fast material removal.
• To operate the bench grinder, always wear safety glasses and turn the tool on while standing at the side and not in front of the grinder. Allow it to reach full speed before grinding.
• Hold the workpiece firmly against the tool rest. Hold very small pieces with pliers or other suitable clamps.
• Feed the workpiece smoothly and evenly into the grinding wheel.
• Move the workpiece slowly and avoid jamming the workpiece against the wheel. If the wheel tends to slow down from excessive force, you should occasionally release the pressure to let the wheel return to full speed.
• The grinding wheels supplied with this unit are designed for different types of steel, wrought iron, and bronze.
• Never sharpen or grind anything made of aluminum, brass, copper, wood, plastic or any other non-metallic materials.
• Warning: Grind only on the face of the grinding wheel and never the side of it.

Warning:
Prolonged grinding will cause most materials to become hot. Use care when handling such materials.

SCISSORS
If possible, take the scissors apart to make the sharpening operation easier and safer. Remove material only from the outside surface and work from the heavy end of the blade toward the tip.

KNIVES
Remove metal from both faces of most knives, working from the heavy end of the blade toward the tip.

SCREWDRIVERS
The end of a properly sharpened screwdriver will be a perfect rectangle, absolutely flat and perpendicular to the center line of the shank. The two sides and two faces will taper outward from the edge of the shoulder or shank. They should be flat with intersecting faces perpendicular. Hold each face of the screwdriver against the wheel to true it up, then ease the end straight into the stone to grind it true.

TWIST DRILL BITS (FIGURE K)
Drill bits are best sharpened on a sharpening jig, available at most hardware stores, but can be “dressed up” on your grinder. Begin on one side of the point at the existing angle, then twist the bit while maintaining a constant angle with grinding surface. Sharpen only the tip. This technique requires considerable practice, so take your time and make a few “dry runs” first with the grinder off. Be sure to maintain the original cutting edge angle as this is important to the efficiency of your bits.

One tool rest has a V-groove that is correctly angled for most drill bits.

LAWN MOWER BLADES
Lawn mower blades are usually sharpened on only one side and dressed up slightly on the other. After sharpening, be sure to balance the blade by removing additional material from the heavy end. There are a number of inexpensive cone balancers on the market for this purpose. Unbalanced blades can cause serious crankshaft damage to your lawn mower. Always remove spark plug wires from the mower before servicing the blades to prevent accidental starting.

DRESSING A GRINDING WHEEL (FIGURE L)
A wheel dressing tool is not provided with the grinder. Place the dressing tool on the tool rest until it touches the high point on the face of the wheel. Dress the wheel by moving the dressing tool back and forth. Repeat this operation until the face of the grinding wheel is clean and the corner of the wheel is square.

NOTE: DO NOT use the wheel dressing tool on wire wheels.

INSTALLING WIRE WHEEL (NOT INCLUDED)
When replacing the grinding wheel with a wire wheel, it is necessary to place a spacer (not included) on the spindle shaft BEFORE installing the inner flange, wheel, outer flange, and wheel nut.

MAINTENANCE

Warning:
For your own safety, turn the switch “OFF” and remove the plug from the power source outlet before adjusting and maintaining your bench grinder. If the power cord is worn, cut, or damaged in any way, have it replaced immediately?

• Regularly check the tool and use a soft brush to remove accumulated dust.
• Use only mild soap and damp cloth to clean the tool. Do not use alcohol, petrol or other similar cleaning agents.
• Do not make contact with the grinding wheels with any damp cloth.
• Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
• Wear safety goggles to protect your eyes while cleaning.
• Always make sure the eyeshields are transparent and not blocking the view of the grinding wheel.
• In normal use, grinding wheels may become cracked, grooved, rounded at the edges, chipped, out of true or loaded with foreign material. Cracked wheels should be replaced IMMEDIATELY. While any of the other conditions can be remedied with a dressing tool (included), new wheels sometimes require dressing to make them round.
• If you must replace a wheel be sure to obtain one with a safe rated speed at least as high as the “NO LOAD” RPM marked on your grinder’s nameplate. Replacement wheels must have a 5/8 in. (15.88 mm) center hole, 8 in. (200 mm) diameter and should be a maximum of 1 in. (25 mm) wide. Test new wheels for cracks and maintain the existing sequence of retaining hardware. Be sure the tool is unplugged before attempting repairs.

Caution:

• Never use caustic agents to clean the plastic parts of the tool.
• Water must never come into contact with the grinder.
• The use of any other accessories is not recommended and may result in serious injury.

Warning:
The use of any accessory not recommended for use with this tool could be hazardous.
