• 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 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.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

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 remove the battery pack, if detachable, 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 and accessories. 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Instructions for Circular Saws

Cutting procedures

• Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
• Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
• Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run off-center, causing loss of control.
• Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback causes and related warnings

Kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator.
When the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator.
If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective action to eliminate the cause of blade binding.
When restarting a saw in the workpiece, center the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.
Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Lower Guard Function

Check lower guard for proper closing before each use. Do not operate saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.
Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
Always observe that the guard is covering the blade before placing the saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the switch is released.

This product is intended to cut wood and wood-like products only. Dust build up around the lower guard and hub from other materials (plastic, masonry or metal) may disable the lower guard operation.
Inspect the condition and quality of the wood and remove all nails from lumber before cutting. Wet lumber, green lumber or pressure treated lumber require special attention during cutting operation to prevent kickback.
Hold the saw firmly to prevent loss of control. Figures in this manual illustrate typical hand support of the saw.
Depending upon use, the switch may not last the life of the saw. If the switch should fail in the “OFF” position, the saw may not start. If it should fail while the saw is running, the saw may not shut off. If either occurs, unplug the saw immediately and do not use until repaired.
This circular saw should not be mounted to a table and converted to a table saw. Circular saws are not designed or intended to be used as table saws.
The blade washers and the bolt on your saw have been designed to work as a clutch to reduce the intensity of a kickback. Understand the operation and settings of the VARI-TORQUE CLUTCH. The proper setting of the clutch, combined with firm handling of the saw will allow you to control kickback. Never place your hand behind the saw blade. Kickback could cause the saw to jump backwards over your hand.
Do not use the saw with an excessive depth of cut setting. Too much blade exposure increases the likelihood of the blade twisting in the kerf and increases the surface area of the blade available for pinching that leads to kickback.
Do not run the tool while carrying it at your side. Lower guard may be opened by a contact with your clothing. Accidental contact with the spinning saw blade could result in serious personal injury.
Periodically remove the blade, clean the upper, lower guards and the hub area with kerosene and wipe it dry. Preventive maintenance and properly operating guard will reduce the probability of an accident.
Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.
Avoid overheating saw blade tips.

Additional Safety Warnings

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.
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.

WARNING 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.

Battery Packs/Chargers
Please refer to the battery/charger list, included with your tool.

Assembly

WARNING Disconnect battery pack from tool before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.

Inserting and Releasing Battery Pack

Use only Bosch or AMPShare batteries recommended in the battery/charger list, included with your tool. Using other types of batteries may result in personal injury or property damage.
Slide charged battery pack into the housing until the battery pack locks into position (Fig. 1).
Your tool is equipped with a secondary locking latch to prevent the battery pack from completely falling out of the handle, should it become loose due to vibration.
To remove the battery pack, press the battery pack release button and slide the battery pack forward.
Press the battery pack release button again and slide the battery pack completely out of tool housing (Fig. 1).

Attaching the Blade

Use only 6-1/2” blade. Use only blade rated 3900/min (RPM) or greater. Using blade not designed for the saw may result in serious personal injury and property damage.

1. Turn BLADE STUD with wrench provided clockwise and remove BLADE STUD and OUTER WASHER (Fig. 2). If the shaft moves while attempting to loosen the blade stud press the lock button (Fig. 1).
2. Make sure the saw teeth and arrow on the blade point in the same direction as the arrow on the lower guard.
3. Retract the lower guard all the way up into the upper guard. While retracting the lower guard, check operation and condition of the LOWER GUARD SPRING.
4. Slide blade through slot in the foot and mount it against the INNER WASHER on the shaft. Be sure the large diameter of the OUTER washer lays flush against the blade.
5. Reinstall OUTER WASHER and tighten BLADE STUD finger tight. The face of upper guard has marks around it that will help you properly adjust the blade stud. Press lock button to lock shaft and TIGHTEN BLADE STUD COUNTER-CLOCKWISE TWO MARKS ON UPPER GUARD WITH THE WRENCH PROVIDED.
   Do not use wrenches with longer handles, since it may lead to over tightening of the blade stud.

VARI-TORQUE CLUTCH
This clutching action is provided by the friction of the OUTER WASHER against the BLADE and permits the blade shaft to turn when the blade encounters excessive resistance. When the BLADE STUD is properly tightened (as described in No. 5 of Attaching The Blade), the blade will slip when it encounters ex cessive resistance, thus reducing saw’s tendency to KICKBACK.
One setting may not be sufficient for cutting all materials. If ex cessive blade slippage occurs, tighten the blade stud one mark more. OVERTIGHTENING THE BLADE STUD NULLIFIES THE EFFECTIVENESS OF THE CLUTCH.

Dust Extraction

WARNING To reduce the risk of injury, always position dust port adapter and vacuum hose so that it does not interfere with the lower guard, or the cutting operation at all settings.

DUST PORT ADAPTER
(Sold separately)
Attach the dust port adapter to the foot of the tool with screw as shown in Fig. 3. CONNECTION TO VACUUM CLEANER / DUST EXTRACTOR
Connect the vacuum cleaner hose to the dust port adapter (Fig. 3).

• Bosch VH-series hoses – The VX120 hose adapter is required (included with VH-series hoses).
• Other 35mm and 22mm hoses, such as the Bosch VAC-series hoses – Connect hose directly to the tool.
• Common 1⁄4″ or 11/2″ hoses – The Bosch VAC024 adapter is required (included).

Connect the vacuum hose to a vacuum cleaner.
The vacuum cleaner must be suitable for the material being worked on.
When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner / dust extractor.

Operating Instructions

WARNING Disconnect battery pack from tool before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.

Depth Adjustment

Disconnect battery pack from tool. Loosen the depth adjustment lever located on the right side of the tool. Hold the foot down with one hand and raise or lower saw by the handle.
Tighten lever at the depth setting desired. Check desired depth (Fig. 4). Not more than one tooth length of the blade should extend below the material to be cut, for minimum splintering (Fig. 5).

90° Cutting Angle Check

Disconnect battery pack from tool. Set foot to maximum depth of cut setting. Loosen bevel adjustment lever, set to 0° on quadrant, retighten lever and check for 90° angle between the blade and bottom plane of foot with a square (Fig. 6).Make adjustments by turning the small alignment screw from bottom side of foot, if necessary (Fig. 7).

Bevel Adjustment

Disconnect battery pack from tool. The foot can be adjusted up to 50° by loosening the bevel adjustment knob at the front of the saw. Align to desired angle on calibrated quadrant. Then tighten bevel adjustment knob (Fig. 8). Because of the increased amount of blade engagement in the work and decreased stability of the foot, blade binding may occur. Keep the saw steady and the foot firmly on the workpiece.

Line Guide

For a straight 90° cut, use left side of notch in the foot. For 45° and 50° bevel cuts, use the right side (Fig. 9). The cutting guide notch will give an approximate line of cut. Make sample cuts in scrap lumber to verify actual line of cut. This will be helpful because of the number of different blade types and thicknesses available. To ensure minimum splintering on the good side of the material to be cut, face the good side down.

Safety Switch

The safety switch is designed to prevent accidental starts. To operate safety switch, press the release button with your thumb on either side of handle to disengage the lock, then pull the trigger (Fig. 10). When the trigger is released the button will engage the safety switch automatically, and the trigger will no longer operate. (See “SWITCH” and “REGULAR CUTS”)

Switch

When starting the tool, hold it with both hands. The torque from the motor can cause the tool to twist.
To turn tool on, press the safety switch release button with your thumb on either side of handle to disengage the lock, then pull the trigger (Fig. 10). To turn the tool “OFF”, release the trigger switch, which is spring loaded and will return to the off position automatically.
Your saw should be running at full speed BEFORE starting the cut, and turned off only AFTER completing the cut. To increase switch life, do not turn switch on and off while cutting.

Brake

When the trigger is released it activates the electrical brake to stop the blade quickly. This feature is especially useful when making repetitive cuts.

Regular Cuts

Always hold the saw handle with one hand and the auxiliary handle or housing with the other.
Always make sure saw foot rests on portion of work surface that does not drop off.
WARNING Always be sure either hand does not interfere with the free movement of the lower guard. Maintain a firm grip and operate the switch with a decisive action. Never force the saw. Use light and continuous pressure.

WARNING After completing a cut and the trigger has been released, be aware of the nec es sary time it takes for the blade to come to a com plete stop during coast down. Do not allow the saw to brush against your leg or side, since the lower guard is retractable, it could catch on your clothing and expose the blade. Be aware of the necessary blade ex posures that exist in both the upper and lower guard areas.
When cutting is interrupted, to resume cutting: squeeze the trigger and allow the blade to reach full speed, re-enter the cut slowly and resume cutting. When cutting across the grain, the fibers of the wood have a ten den cy to tear and lift. Advancing the saw slowly minimizes this effect. For a finished cut, a cross cut blade or miter blade is rec om mended.

Cutting Masonry/Metal

This tool is not recommended for usage with metal or masonry cut-off wheels.
WARNING Do not cut metal or masonry with this circular saw. The dust from metal or masonry cutting will cause the lower guard to become sluggish and may not close fully and quickly after cutting these materials.
WARNING Do not use abrasive wheels with circular saws.
Abrasive dust may cause lower guard to fail.
WARNING Do not use Wet Diamond cutting off wheel or water
feed devices with this circular saw. Masonry cutting waste will enter the lower guard system, harden and cause the guard to become inoperable. Use of water in masonry cutting applications with an electric circular saw will cause electric shock hazards.

Plunge Cuts

Disconnect battery pack from tool before making ad justments. Set depth adjustment according to material to be cut. Reattach battery pack to the saw. Tilt saw forward with cutting guide notch lined up with the line you’ve drawn. Raise the lower guard, using lift lever and hold the saw by the front and rear handles (Fig. 11). With the blade just clearing the material to be cut, start the motor. Gradually lower the back end of saw using the front end of the foot as the hinge point.

WARNING As blade starts cutting the material, release the lower guard immediately. When the foot rests flat on the surface being cut, proceed cutting in forward direction to end of cut.
WARNING Allow blade to come to a complete stop before lifting the saw from cut. Also, never pull the saw backward since blade will climb out of the material and KICKBACK will occur. Turn saw around and finish the cut in the normal manner, sawing forward. If corners of your pocket cut are not completely cut through, use a jigsaw or hand saw to finish the corners.

Cutting Large Sheets

Large sheets and long boards sag or bend, depending on support. If you attempt to cut without leveling and properly supporting the piece, the blade will tend to bind, causing KICK-BACK and extra load on the motor (Fig. 12). Support the panel or board close to the cut, as shown in (Fig. 13). Be sure to set the depth of the cut so that you cut through the sheet or board only and not the table or work bench. The two-by-fours used to raise and support the work should be positioned so that the broadest sides support the work and rest on the table or bench. Do not support the work with the narrow sides as this is an unsteady arrangement. If the sheet or board to be cut is too large for a table or work bench, use the supporting two-by-fours on the floor and secure.

Rip Cuts

The combination blade provided with your saw is for both cross cuts and rip cuts. Ripping is cutting lengthwise with the grain of the wood. Narrow rip cuts are easy to do with a rip fence (Fig. 14). To attach optional rip fence, insert fence through slots in foot to desired width as shown and secure with the knob.
WARNING After attaching or adjusting the rip fence, be sure the rip fence does not touch or interfere with the free movement of the lower guard or contact the saw blade.

Rip Board Guide

When rip cutting large sheets, the rip fence may not allow the desired width of cut. Clamp or nail a straight piece of 1″ (25 mm) lumber to the sheet as a guide (Fig. 15). Use the right side of the foot against the board guide.

Maintenance

WARNING To avoid accidents, always disconnect battery pack from tool before cleaning or performing any maintenance.

Service

NO USER SERVICE-ABLE PARTS INSIDE. Preventive maintenance performed by un au- thorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recom mend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station.

Batteries

Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger.

Tool Lubrication

Your Bosch tool has been properly lubricated and is ready for use.

D.C. Motors

The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used.

Bearings

Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating and motor failure.

Cleaning

caution Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, car bon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through opening.
Periodically remove the blade, clean the upper, lower guards and the hub area with kerosene and wipe it dry. Preventive maintenance and properly operating guard will reduce the probability of an accident.

Care of Blades

Blades become dull even from cutting regular lumber. If you find yourself forcing the saw forward to cut instead of just guiding it through the cut, chances are the blade is dull or coated with wood pitch.
When cleaning gum and wood pitch from blade, remove the battery from the saw and remove the blade. Remember, blades are designed to cut, so handle carefully. Wipe the blade with kerosene or similar solvent to remove the gum and pitch. Unless you are experienced in sharpening blades, we recommend you do not try.

Accessories and Attachments

WARNING The use of any other attachments or acces so ries not specified in this manual may create a hazard.

Store accessories in a dry and temperate environment to avoid corrosion and deterioration.

OUR SOLE OBLIGATION AND YOUR EXCLUSIVE REMEDY under this Limited Warranty and, to the extent permitted by law, under any warranty or condition implied by law, shall be the repair or replacement of parts, without charge, which are defective in material or workmanship and which have not been abused, misused, carelessly handled, or repaired by persons other than Bosch or a Bosch Authorized Service Center.
Normal wear and tear of your Product is not covered by this Limited Warranty. As a result, Product parts that may become worn or exhausted over time due to normal wear and tear (including, without limitation, air filters, blade clamps, brushes, bumpers, bumper cover washers, chucks, cords, driver belts, driver blades, isolators, lifters, o-rings, pistons, piston/driver assemblies, piston stops, saw shoes, seals, strikers, etc.), or any other service or repairs required due to normal wear and tear on a Product, are not covered by this Limited Warranty.
To make a claim under this Limited Warranty, you must return the complete Product, transportation prepaid, to any Bosch Factory Service Center or Bosch Authorized Service Center. Please include a dated proof of purchase with your Product so we can determine if your Product is within the Warranty Period. If you do not have the dated proof of pur-chase for the Product that is the subject of your claim, we will use the Product’s production code to determine whether the Product is within the Warranty Period.
