•
Cheek the operetlon and condiUon 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 sluggishlydue to
damaged parts, gummy deposits,or a buildupof debris.
•
Lower guard should be retracted manually only for
special cuts such as "Pocket Cuts" and =Com-
pound Cuts". Raise lower guard by Retracting
Handle. As soon as blade enters the meterlal, lower
guard muet be released. For all other sawing, the
lowerguard should operate automatically,
•
Always observe that the lower guard Is covering the
blade before placing saw down on bench or floor.
An unprotected,coastingblade will cause the saw to
walk backwards, cuttingwhatever is in itspath. Be
aware ofthe 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 importantto supportthe work
properlyto minimizebody exposure, blade binding,or
lossof control.
•
Hold tool by Insulating gdpplng sndaces 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 tool "live"and
shockthe operator.
•
When ripping always use a dp fence for a etralght
edge guide. This improvesthe accuracy of cut and
reduces the chance of blade binding.
•
Always use blades with correct size and shape
(diamond vs. round) arbor holes. Bladesthat do not
match the mounting hardware of the saw will run
eccentrically, c ausing loss of central.
•
Never use damaged or Incorrect blade washers or
bolts. The blade washers and boltwere specially
designedfor your saw, for optimumperformanceand
safety of operation.

Causes and Operator Prevention of Kickback:
Kickbackis a sudden reaction to a pinched, bound, or
misaligned saw blade, causing an uncontrolledsaw to
liftup and out of the workpiece towardthe operator.
When the blade is pinchedor bound tightlyby the ked
closingdown, the blade stalls and the motor reaction
drivesthe unitrapidlyback towardthe operator.
If the blade becomes twisted or misalignedin the cut,
the teeth at the back edge of the blade can dig into the
top surface of the wood causing the blade to climbout
of the kerfand jump back toward the operator.
Kickbackis a result of tool misuse and/or incorrect
operating proceduresor conditionsand can be avoided
by taking proper precautionsas givenbelow:
•
Maintain a firm grip on the saw and position your
body and arm In a way that allows you to resist
KICKBACK forces. KICKBACK forces can be con-
trolledbyth_ operator, if properprecautions are taken.
• When blade Is binding, or when Interrupting a cut
for any reason, release the trigger and hold the saw
motionless In the metedal 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. Investi-
gate and take correctiveactions to eliminate the cause
of blade binding.
•
When restarting a saw in theworkplace, center the
saw blade In the kerf end check that 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.
•
Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panelstend 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.
•
Do not use dull or damaged blade. Unsharpened or
improperlyset blades produce narrow kerf causing
excessivefriction,blade binding, and KICKBACK.
•
Blade depth and bevel adJuetlng locking levers
must be tight and secure before making cut, If blade
adjustment shiftswhile cutting, itwill cause binding and
KICKBACK.
• Use utra caution when making e =Pocket CUt'* into
e_lstlng walls or ether blind areas. The protruding
blade may cut objectsthat can cause KICKBACK.
