n 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.

n 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. (See “Causes

And Operator Prevention Of Kickback” later.)

n Do not reach underneath the work. The guard cannot

protect you from the blade below the work.

n 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.

n 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.

n 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.

n 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.

n 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.

n Hold 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.

SERVICE

n Tool service must be performed only by qualified re-

pair personnel. Service or maintenance performed by

unqualified personnel may result in a risk of injury.

n 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.

n 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.

n Never use damaged or incorrect blade washers

or bolts. The blade washers and bolts were specially

designed for the 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 tool misuse and/or incorrect operating

procedures or conditions and can be avoided by taking proper

precautions, as given below:

n Maintain a firm grip with both hands on the saw and

position your body and arm to allow you to resist

KICKBACK forces. KICKBACK forces can be controlled

by the operator, if proper precautions are taken.

n 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.

n 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 saw blade is binding,

it may walk up or KICKBACK from the workpiece as the

saw is restarted.

n When servicing a tool, use only identical replacement

parts. Follow instructions in the Maintenance section

of this manual. Use of unauthorized parts or failure to fol-

low Maintenance Instructions may create a risk of shock

or injury.
