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 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 a 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 tool in unexpected situations.

Dress properly. Do not wear loose clothing or jewelry. Keep your hair, and clothing 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 behavior 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.

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.

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 saw 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 actions 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 the 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 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 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 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 switch is released.

ADDITIONAL SAFETY WARNINGS

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, cement, and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

• Your risk from these exposures varies, depending upon how often you do this type of work. To reduce your exposure to these chemicals:

• Work in a well-ventilated area.
• Work with approved safety equipment, such as 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 or eyes or to lie on the skin may promote absorption of harmful chemicals.

ATTACHING THE BLADE (FIG. 3)

This tool is for cutting wood only. Use only the correct saw blades for wood-cutting operations. Do not use any abrasive wheels.

Use only 7-1/4" saw blades rated 6200/min (RPM) or greater. NEVER use a blade that is so thick that it prevents the outer blade washer from engaging with the flat side of the spindle.

Using a blade not designed for the saw may result in serious personal injury and property damage.

Be sure to wear protective work gloves while

handling a saw blade. The blade can injure unprotected hands.

a. Detach the battery pack.
b. Press the spindle lock and turn the blade bolt with included blade wrench until the lock engages. The spindle is now locked. Continue to depress the spindle lock, turn the blade wrench clockwise, and remove the blade bolt and the outer washer. Always clean the spindle, washers, upper guard, and lower guard to remove any dirt and sawdust.

Depress the spindle lock only when the tool is at a

standstill.

c. Make sure that the saw teeth and the arrow on the blade point in the same direction as the arrow on the lower guard.
d. Retract the lower guard all the way up into the upper guard. While retracting the lower guard, check the operation and condition of the lower guard system.
e. Slide the blade through the slot in the foot and mount it against the inner washer on the shaft. Be sure that the clamping surfaces of the inner and outer washers lay flush against the blade.

Make sure that the clamping surfaces of the inner and outer washers are perfectly clean and face the blade.

f. Reinstall the outer washer. First finger-tighten the blade bolt, then tighten the blade bolt 1/8 turn (45°) with the blade wrench (this ensures slippage of the saw blade when it encounters excessive resistance, thus reducing motor overload and saw kickback).

NOTICE: Do not use a blade wrench with a longer handle, since it may lead to over tightening of the blade bolt.

ADJUSTMENTS

Detach the battery pack from the tool before

performing any assembly, adjustments, or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.

DEPTH-OF-CUT ADJUSTMENT (FIG. 4a & 4b)

Your tool is equipped with a depth-of-cut adjustment lever, located beside the upper guard.

To set the depth of cut:

a. Remove the battery pack from the circular saw.
b. Loosen the depth-adjustment lever by pushing it up (Fig. 4a).
c. Hold the foot of the saw flat against the edge of the workpiece and use the main handle to raise or lower the saw. Align the bottom contour of the depth-adjustment lever with the desired depth-of-cut mark on the calibrated depth bracket and tighten the lever (Fig. 4a).

NOTICE: Check the desired depth. Not more than one tooth length of the blade should extend below the material to be cut to minimize splintering (Fig. 4b).

The four most common cutting depths are marked on the calibrated depth bracket. These settings help the operator to quickly set the saw to cut through the material with thickness of 1/4", 1/2", 3/4" plywood, 1x, 2x, and 3x lumber respectively, while allowing one tooth length of the blade to extend below the material.

INTENDED USE

This tool is designed to perform all wood-cutting applications: general cuts, cross cuts, rip cuts, and plunge cuts. Only use with wood materials.

NOTICE: The tool is not designed for metal

or masonry cutting. Dust and chips from those materials will impact lower guard function.

WARNING

Do not use abrasive wheels with circular saws.

Abrasive dust may cause lower guard to not operate properly.

GENERAL CUTS

Always be sure that neither hand interferes

with the free movement of the lower guard.

After completing a cut and releasing the trigger, be

aware of the necessary time it takes for the blade to come to a complete 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 exposures that exist in both the upper and lower guard areas.

Always hold the saw by the main handle with one hand and the auxiliary handle with the other. 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. To resume cutting after cutting is interrupted, press the lock-off button, squeeze the trigger, and allow the blade to reach full speed, then re-enter the cut slowly, and resume cutting. When cutting across the grain, the fibers of the wood have a tendency to tear and lift. You can minimize this effect by advancing the saw slowly. For a finished cut, a cross cut blade or miter blade is recommended.

PLUNGE CUTS (FIG. 13)

a. Remove the battery pack from the circular saw.
b. Set the depth adjustment according to the thickness of the material to be cut.
c. Attach the battery pack.
d. Hold the main handle of the saw with one hand, tilt the saw forward, and rest the front of the foot plate on the material to be cut. Align the cutting-guide notch with the line you've drawn. Use the lower-guard lift lever to raise the lower guard until you are able to grasp and hold the auxiliary handle with the other hand.
e. Position the saw so that the blade is just clearing the material to be cut. Start the saw and, once it is fully up to speed, use the front edge of the foot as a hinge point to gradually lower the back end of the saw.
f. Once the foot plate rests flat on the surface being cut, release the lower-guard lift lever. Proceed cutting in the forward direction to the end of cut.

WARNING

Allow the blade to come to a complete stop before

lifting the saw from the cut. Also, never pull the saw backward, since the blade will climb out of the material and KICKBACK will occur.

CUTTING LARGE SHEETS (FIG. 14)

Large sheets and long boards can 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.

Support the panel or board close to the cut. 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 that is supporting it. The two-by-fours used to raise and support the work should be positioned so that the wide 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 secured in place.

RIP CUTS (FIG. 15)

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. Rip cuts are easy to do with a rip fence. Rip fence FLEX FT211 is available as an accessory (not included). To attach a fence, insert the fence through the slots in the foot to the desired width as shown, and secure it with the thumb screw (included in the rip fence kit).

WARNING

Ensure that the rip fence does not interfere with the

free movement of the lower guard and saw blade. A rip fence contacting the lower guard or saw blade can cause property damage and serious personal injury.

Fig. 15 Desired Width of Cut FLEX Rip Fence

RIP BOARD GUIDE (FIG. 16)

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. Use the right side of the foot against the board guide.

MAINTENANCE

To avoid serious personal injury, always remove the battery pack from the tool when cleaning or performing any maintenance.

SERVICE

Preventive maintenance performed by

unauthorized personnel may result in misplacing of internal wires and components which could cause a serious hazard. We recommend that all tool service be performed by a FLEX Factory Service Center or Authorized FLEX Service Station.

GENERAL MAINTENANCE

When servicing, use only identical replacement parts. Use of any other parts could create a hazard or cause product damage. Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced. Please contact customer service or an authorized service center for assistance.

CLEANING

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, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

Storage

Store the tool indoors in a place that is inaccessible to children. Keep away from corrosive agents.

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, detach the battery pack and remove the blade. Remember, blades are designed to cut, so handle them carefully. Wear gloves and 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

The use of any other accessories not specified in this manual may create a hazard.
