Keep your body positioned to either side of the saw blade, but not

"Causes and Operator Prevention of Kickback")

Do not reach underneath the work while blade is rotating. The guard can
not protect you from the blade below the work. Don't attempt to remove cut

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
opera tor.

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

of

the wood causing the blade

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.

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.

When blade is binding, or when interrupting a cut for any reason, release
the trigger and hold the saw motionless

may walk up or KICKBACK from the workpiece as the saw is

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

Do

not use dull or damaged blade. Unsharpened or improperly 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 making a "Pocket Cut" into existing walls or other

blind areas. The protruding blade may cut objects that can cause KICKBACK.

NEVER

place your hand or fingers
behind the saw. If kickback occurs,
the saw could easily jump backwards
over your hand, possibly causing
severe injury.

Adjustments. Before cutting be sure depth and bevel adjustments are tight.

Avoid Cutting Nails. Inspect for and remove all nails from lumber before

cutting.
