GENERAL SAFETY RULES

■ Check for misalignment or binding of moving

parts, breakage of parts, and any other condi-

tion that may affect the tool’s operation. If dam-

aged, have the tool serviced before using. Many

accidents are caused by poorly maintained tools.

■ Use only accessories that are recommended by

the manufacturer for your model. Accessories that

may be suitable for one tool, may become hazard-

ous when used on another tool.

SERVICE

■ Tool service must be performed only by quali-

fied repair personnel. Service or maintenance per-

formed by unqualified personnel could result in a risk

of injury.

■ When servicing a tool, use only identical replace-

ment parts. Follow instructions in the Mainte-

nance section of this manual. Use of unauthorized

parts or failure to follow Maintenance Instructions

may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

■ DANGER! Keep hands away from cutting area

and blade. Keep your second hand on the

auxiliary handle or motor housing. If both hands

are holding the saw, they cannot be cut by the blade.

■ Keep your body positioned to either side of the

saw blade, but not in line with the saw blade.

Kickback could cause the saw to jump backwards.

(Refer to “CAUSES AND OPERATOR

PREVENTION OF KICKBACK” later.)

■ Do not reach underneath the work. The guard

cannot protect you from the blade below the work.

■ Check lower guard for proper closing before

each use. Do not operate 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. 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 and condition 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 buildup of

debris.

■ Lower guard should be retracted manually only

for special cuts, such as "Pocket Cuts" and

"Compound Cuts." Raise lower guard by

retracting handle. As soon as blade enters the

material, 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 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.

■ NEVER hold piece being cut in your hands or

across your leg. It is important to support the work

properly to minimize body exposure, blade binding,

or loss of control.

■ Hold tool by insulated gripping surface 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 tool “live” and shock the operator.

■ When ripping, always use a rip fence or straight

edge guide. This improves the accuracy of the cut

and reduces the chance for blade binding.

■ Always use blades with correct size and shape

(diamond vs. round) 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 bolts. The blade washers and bolts 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.
