Service

 Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. This will en-

sure that the safety of the power tool is maintained.

Safety Warnings for Circular Saws

Cutting procedures

 DANGER: Keep hands away from the cutting area and

the saw blade.

 Do not reach underneath the workpiece. The guard can-

not protect you from the blade below the workpiece.

 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.

 Never hold piece being cut in your hands or across your

leg. Secure the workpiece to a stable platform. It is im-

portant to support the work properly to minimize body ex-

posure, blade binding, or loss of control.

 Hold power tool by the insulated gripping surfaces,

when performing an operation where the cutting tool

may run into hidden wiring. Contact with a “live” wire will

make exposed metal parts of the tool “live” and shock the

operator.

 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 (dia-

mond versus round) of arbour holes. Blades that do not

match the mounting hardware of the saw will run eccentri-

cally, 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, 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 oper-

ating procedures or conditions and can be avoided by tak-

ing proper precautions as given below.

 Maintain a firm grip on the saw and position your arms

to allow you to resist kickback force. Always stay to the

side of the saw blade, never putting the saw blade in

line with your body. The saw can jump backwards in the

event of kickback, but the operator can control kickback

force if proper precautions are taken.

 When blade is binding, or when interrupting a cut for

any reason, release the trigger and hold the saw mo-

tionless in the material until the blade comes to a com-

plete stop. Never attempt to remove the saw from the

work or pull the saw backward while the blade is in mo-

tion or kickback may occur. Investigate and take correc-

tive actions to eliminate the cause of blade binding.

 When restarting a saw in the workpiece, centre the saw

blade in the kerf and check that saw teeth are not en-

gaged into the material. If saw blade is binding, it may walk

up or kickback from the workpiece as the saw is restarted.

 Support large panels to minimise the risk of blade

pinching and kickback. Large panels tend to sag under

their own weight. Supports must be placed under the pan-

el on both sides, near the line of cut and near the edge of

the panel.

 Do not use dull or damaged blades.

Unsharpened or im-

properly 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 the saw if lower guard does not move

freely and close instantly. Never clamp or tie the lower

guard into the open position. If saw is accidentally

dropped, 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 angle cuts”. Raise

the lower guard by retracting the handle and as soon as

the blade enters the material, release the lower guard.

For all other sawing operations, the lower guard should op-

erate automatically.

 Always observe that the lower guard is covering the

blade before placing saw down on bench or floor. An un-

protected, coasting blade will cause the saw to walk back-

wards, 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

 Do not reach into the saw dust ejector with your hands.

They could be injured by rotating parts.

 Do not work overhead with the saw. In this manner you

do not have sufficient control over the power tool.

 Use appropriate detectors to determine if utility lines

are hidden in the work area or call the local utility compa-

ny for assistance. Contact with electric lines can lead to fire

and electric shock. Damaging a gas line can lead to explo-

sion. Penetrating a water line causes property damage.
