WARNING: Read all safety warnings and instructions. Failure to follow the warnings

and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

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 residual current device (RCD) protected supply. Use of a ground fault

circuit interrupter (GFCI) reduces the risk of electric shock.

Personal safety Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while

operating power tools may result in serious personal injury.

Use personal protective equipment. Always wear eye protection. Protective equipment

such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.

Remove any adjusting key or wrench before turning the power tool on. A wrench or a key

left attached to a rotating part of the power tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power 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 SAFETY

Page 6

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.

Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live"

wire will make exposed metal parts of the tool "live" and shock the operator.

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against

your body leaves it unstable and may lead to loss of control.

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.

POWER TOOL SAFETY

SAVE THESE INSTRUCTIONS FOR REFERENCE

Page 7

WARNING: Know your circular saw. Do not plug the circular saw into the power source until you have read and understand

this Instruction Manual. Learn the tool’s

applications and limitations, as well as the specific potential hazards related to this tool.

Following this rule will reduce the risk of electric shock, fire, or serious injury.

Always wear eye protection. Any power tool can

throw foreign objects into your eyes and cause permanent eye damage. ALWAYS wear safety

goggles (not glasses) that comply with ANSI safety standard Z87.1. Everyday glasses have only impact resistant lenses. They ARE NOT safety glasses.

WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could cause serious injury when they break.

Always keep hands out of the path of the saw blade. Avoid awkward hand positions where a sudden slip could cause your hand to move into the path of the saw blade.

DANGER: Keep hands away from cutting area and the blade. Keep your second hand on the tool. 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 according to the thickness of the workpiece. Less than a full

tooth of the blade teeth should be visible below the workpiece or approximately 3/8" (10 mm).

Never hold piece being cut in your hands or across your leg. 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 power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live”

wire will also make exposed metal parts of the power tool “live” and shock the operator.

When ripping always use a straight edge guide. This improves the accuracy of cut and

reduces the chance of the 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 eccentrically, 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.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

Kickback is a sudden reaction to a pinched, bound 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 bound 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 the left or right 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.

SPECIFIC SAFETY RULES

Page 8

CAUSES AND OPERATOR PREVENTION OF KICKBACK – cont’d

When the 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 and check that saw teeth are not engaged into the material. If the saw blades are binding, 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.

ADDITIONAL SPECIFIC SAFETY RULES Use extra caution when making a "plunge

cut" into existing walls or other blind areas.

The protruding blade may cut objects that can cause kickback.

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 damaged. 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 depths of cuts.

Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. The lower guard may operate

sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

The lower guard should be retracted manually only for special cuts such as "plunge cuts" and "compound cuts". Raise lower guard by 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 saw down on the bench or on the 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.

Never operate the saw while it is being carried to another location. The blade guard may be open and potentially cause serious injury.

If the switch fails to turn the saw ON or OFF properly, stop using it immediately and have the saw switch repaired.

Always allow the saw to reach full speed before beginning the cut.

Never use the side of the blade for cutting. When making horizontal cuts, make sure the weight of the tool is not forcing the side of the blade to do the cutting. This will reduce the risk of kickback.

Make sure there are no nails or foreign objects in the area of the workpiece to be cut.

Never lay workpiece on hard surfaces like concrete, stone, etc. The protruding blade may

cause tool to jump. DANGER: To avoid injury from

accidental starting, always remove the plug from the power source before making any adjustments and before installing or removing a saw blade.

SPECIFIC SAFETY RULES

Page 9

ADDITIONAL SPECIFIC SAFETY RULES – cont’d

When replacing the blade, make sure the replacement blade is 7 1/4" in diameter and is rated for 7,000 RPM. Installing an incorrect

blade will result in possible injury and poor cutting action.

After changing a blade or making adjustments, make sure the blade clamp screw is securely tightened. Loose blades

and adjustment devices will be violently thrown.

Never touch the blade during or immediately after use. After use the blade is too hot to be

safely touched with bare hands.

TRIGGER SWITCH

1. To turn the saw ON, squeeze the trigger switch (1) (Fig. 9).

WARNING: Never carry the saw with

your finger on the trigger switch. The saw could be accidentally started and cause severe personal injury.

2. To turn the saw OFF, release the trigger switch.

MATERIALS THAT YOU CAN CUT

The circular saw is a versatile saw that allows you to cut many different types of materials. Some of the materials include:

● Wood products such as lumber, hardwood,

plywood, composit board and panelling

● Drywall

● Masonite and plastic

NOTE: There are several different types of blades available. Generally, blades with carbidetipped teeth cut better and stay sharp longer. Tooth count and configuration are also important. High tooth counts cut slower, and are best suited for making smooth cuts on thinner materials such as panelling. Use the correct blade for your application.

GENERAL CUTTING

1. Make any adjustments to the saw before installing the blade. Adjustments include cutting depth, cutting angle and rip guide (if installed).

2. Clearly mark the workpiece to locate the position of the cut.

3. Hold a smaller workpiece with a vise. Clamp a larger workpiece to a workbench or table.

DANGER: Any workpiece that is not

adequately clamped in place may come loose and cause serious injury. Never hold the workpiece in your hand.

4. Make sure there are no nails, screws, clamps or foreign materials in the path of the saw blade.

5. With both hands firmly gripping the saw, and with the blade NOT in contact with the surface to be cut, start the saw by squeezing the trigger switch.

6. Once the saw has reached full speed, place the front edge of the sole plate on the workpiece and gradually bring the moving blade into contact with the workpiece at the appropriate location.

ASSEMBLY AND OPERATING

Fig. 9

Page 16

GENERAL CUTTING – cont’d NOTE: To align the saw blade with the cutting

mark, use the guide marks on the front of the sole plate (Fig. 10). Use the 0° cutting mark (1) for right angle cuts. Use only the 45° mark (2) for 45° cuts. The 45° mark will allow for the extra material needed for the angle cut. Always make a test cut on a scrap workpiece before cutting the new material.

WARNING: Do not force the circular saw. Use only enough force to keep the blade cutting at full speed. Excessive pressure on the blade will cause it to slow down and overheat, resulting in poor cut quality and damage to the motor.

RIP GUIDE CUTTING

1. Set the rip guide foot at the required width

(Fig. 7).

NOTE: When starting the cut, make sure the blade is parallel to the edge of the workpiece and the rip guide foot is against the edge of the workpiece.

2. Proceed with the cut as outlined in

"GENERAL CUTTING" above.

NOTE: As you move the saw through the workpiece, make sure the guide foot stays in contact with the workpiece.

PLUNGE CUTTING WARNING: To avoid loss of control,

damage to the blade or damage to the workpiece, always use extreme caution when making plunge cuts. It is not recommended to plunge cut any material other than wood.

1. To plunge cut inside the edges of a workpiece, clearly mark the cutting line on the workpiece.

2. Set the bevel angle to 0° (Fig. 5).

3. Lift the cutting depth locking lever upward to allow the blade to rise above the bottom of the sole plate so the blade will NOT contact the workpiece (Fig. 4). Do NOT lock the cutting depth locking lever.

4. Set the saw on the workpiece (1) so the sole plate is flat on the workpiece (Fig. 11).

5. Open the blade guard by rotating the blade guard lever (2) forward.

6. Align the saw blade with the cutting line (3) using the 0° cutting mark on the sole plate.

NOTE: Make sure the saw blade is inside the area to be cut out.
