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.

Further Safety Instructions for All Saws

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:

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 actions to

eliminate the cause of blade binding.

c ) 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 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 the 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 kickback.

Lower Guard Function Safety

Instructions

a ) Check the 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.

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 retracting handle and as soon as 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 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.
