b. 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

1. Cutting procedures

a. 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.
b. Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
c. 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.
d. 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.
e. 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.

f. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
g. 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.
h. 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.

2. 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

4 SAVE THESE INSTRUCTIONS

Safety Instructions for Circular Saws

the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

a. 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.

b. 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.

c. 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.

d. 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.

e. Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.

f. 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.

g. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kick-back.

KICKBACK

3. Lower Guard Function

a. Check the lower guard for proper closing before each use. Do not operate the saw if the 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 lower guard lift lever and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

b. 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.

c. The lower guard may be retracted manually only for special cuts such as "plunge cuts" and "compound cuts". Raise the lower guard by the lower guard lift lever 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.

d. Always observe that the lower 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.

SAVE THESE INSTRUCTIONS 5

Additional Safety Instructions for Circular Saws

a. 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.
b. Hold the saw firmly to prevent loss of control. Figures in this manual illustrate typical hand support of the saw.
c. 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, remove the battery pack from the saw immediately and do not use until repaired.
d. 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.
e. 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.

f. Never place your hand behind the saw blade. Kickback could cause the saw to jump backwards over your hand.
g. 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.
h. 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.
i. Periodically remove the blade, clean the upper, lower guards and the hub area. Wipe it dry. Preventive maintenance and properly operating guard will reduce the probability of an accident.
j. 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.
k. 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.

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 pow-er 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.

Saw Assembly

1. Slide Blade 25 through slot in the Foot 15 and mount it against the Inner Washer 24 on the Shaft 23. Be sure the large diameter of the Outer Washer 26 lays flush against the blade (Fig. 2).
2. Reinstall outer washer and tighten Blade Stud 27 finger tight in the direction a. Press and hold Lock Button 4 to lock shaft and TIGHTEN BLADE STUD COUNTER-CLOCK-WISE 1/4 TURN WITH THE WRENCH PROVIDED (Fig. 2).

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 26 against the Blade 25 and permits the blade shaft to turn when the blade encounters excessive resistance. When the Blade Stud 27 is properly tightened (as described in No. 5 of Attaching The Blade), the blade will slip when it encounters excessive resistance, thus reducing saw's tendency to KICKBACK.

One setting may not be sufficient for cutting all materials. If excessive blade slippage occurs, tighten the blade stud a fraction of a turn more (less than 1/8 turn). OVERTIGHTENING THE BLADE STUD NULLIFIES THE EFFECTIVENESS OF THE CLUTCH.

Dust Extraction

(Fig. 3)

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

WARNING Be extremely careful when disposing of dust. Materials

in fine particle form may be explosive. Do not throw sawdust on an open fire. Spontaneous combustion, in time, may result from the mixture of oil or water with dust particles.

DUST PORT

The Dust Port 18 swivels so that dust can be directed in the desired direction.

- Common 1 14 " or 1 12 " hoses - The Bosch VAC024 adapter is required (sold separately).

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

Brake Action

⚠ WARNING Let the saw blade come to a complete stop before setting the tool down. The brake action of this circular saw is not intended as a safety feature. Unintended contact with a rotating saw blade can cause property damage and/or personal injury.

WARNING Know the charge state of your battery. The electric braking action is initiated ONLY by the release of the trigger switch and in a tool that has power available. When electrical power is lost due to a discharged battery or other causes, the electric brake will not operate and the motor will gradually slow down. Unexpected run down time may cause property damage and/or personal injury.

Your circular saw is equipped with an automatic electric brake, which is designed to stop the saw blade from spinning in approximately two (2) seconds after you release the trigger switch. This feature helps improve jobsite productivity.

Braking starts once the power is turned off. The brake requires a charged battery to function.

Stopping time will vary depending on, among other factors, saw blade used, and number of actuations. The electric brake of your circular saw has been designed for a high degree of reliability, but unexpected circumstances such as contamination or failure of the motor's components can cause the brake to not activate. If the tool operates but the brake does not consistently stop the blade in about 2 seconds, DO NOT use the circular saw and have it serviced by a Bosch Factory Service Center or Bosch authorized service facility.

Protection Against Deep Discharging

The lithium ion battery is protected against deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is empty, the tool is switched off by means of a protective circuit.

Overload Protection

Your saw is equipped with Electronic Motor Protection (EMP), which shuts the tool off under overload conditions that could damage the tool. This feature can be reset by simply releasing the trigger and re-engaging the trigger again to restart the tool.

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

(Fig. 4, 5)

WARNING

Adjust the cutting depth so that no more than one tooth

is visible below the work piece. Excessive blade exposure below the workpiece could result in personal injury and/or property damage.

WARNING

The depth adjustment sys- tem should be not used to

change the depth while the saw is in operation, or for plunge cutting. If blade adjustment shifts while cutting, it may cause binding and kickback.

To adjust the cutting depth follow these instructions (Fig. 4):

1. Disconnect Battery Pack 19 from tool.
2. Loosen the Depth Adjustment Lever 7 located on the left side of the tool.
3. Hold the Foot 15 down with one hand and raise or lower saw by the Handle 22.

— For a smaller cutting depth, pull the saw away from the Foot 15;
— for a deeper cutting depth, push the saw toward the Foot 15. The Cutting Depth Scale 21 has an inch scale.

1. Tighten the depth adjustment lever at the desired depth setting.

Note: Not more than one tooth length of the blade should extend below the material to be cut, for minimum splintering (Fig. 5). There is also a secondary scale visible on the lower guard.

90° Cutting Angle Check

(Fig. 5, 6)

1. Disconnect Battery Pack 19 from tool.
2. Set foot to maximum depth of cut setting.
3. Loosen Adjustment Lever 9, set to 0° on Bevel Scale 8, retighten lever 9 (Fig. 5).

Operating Instructions

1. Check for 90° angle between the blade and bottom plane of Foot 15 with a square (Fig. 6). If necessary, make adjustments by turning the small alignment screw from bottom side of Foot 15 with a 2.5 mm allen wrench [not included] (Fig. 6).

Bevel Adjustment

(Fig. 5)

1. Disconnect Battery Pack 19 from tool.
2. Loosen the Bevel Adjustment Lever 9.
3. Align to desired angle on the Bevel Scale 8. The foot can be adjusted up to 50°.
4. Tighten Bevel Adjustment Lever 9.

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.

Cutting Line Guide Notches

(Fig. 7, 8)

The marked notches 11 and 12 at the front of the footplate indicate the approximate line of the cut (Fig. 7).

• For a non-bevelled cut, use 0° Notch 12.
- For 45^ and 50^ bevel cuts, use 45^ Notch 11.
- To ensure minimum splintering on the good side of the material to be cut, face the good side down.
- Make sample cuts in scrap lumber to verify actual line of cut. This will be helpful because of the variety of blade types and thicknesses that are available.
- Use RIGHT side of notch when the part of the workpiece that is to the left of the blade is the scrap piece (Fig. 7).
- Use LEFT side of notch when the part of the workpiece that is to the right of the blade is the scrap piece (Fig. 8).

Operating Instructions

All Cuts

WARNING

Always be sure either hand does not interfere with the

free movement of

the lower guard.

WARNING

After completing a cut and the trigger has been re-

leased, 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.

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.

Maintain a firm grip and operate the switch with a decisive action. Never force the saw. Use light and continuous pressure.

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 recommended.

Plunge Cuts

(Fig. 11)

WARNING

Adjust the cutting depth to the thickness of the work-

piece. Less than a full tooth of the blade teeth should be visible below the workpiece.

WARNING

The depth adjustment sys- tem should be not used to

change the depth while the saw is in operation, or for plunge cutting. If blade adjustment shifts while cutting, it may cause binding and kickback.

WARNING

As blade starts cutting the ma terial, 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.

Disconnect battery pack from tool before making adjustments. 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 16 and hold the saw by the front and rear handles.

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 15 as the hinge point.

Operating Instructions

Cutting Large Sheets

(Fig. 12, 13)

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 KICKBACK 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

(Fig. 14)

⚠ 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.

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. To attach optional Rip Fence 13, insert fence through slots in Foot 15 to desired width as shown and secure with the Wing Bolt 6.

Maintenance

WARNING

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

Service

WARNING

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 recommend 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.

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.

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.

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.
