a. Maintain a firm grip with both hands on the
saw and position your arms to resist kick-
back 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 con-
trolled by the operator, if proper precautions
are taken.
b. When blade is binding, or when interrupt-
ing a cut for any reason, release the trigger
and hold the saw motionless in the mate-
rial 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 so that the
saw teeth are not engaged into the mate-
rial. 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 pan-
els tend to sag under their own weight. Sup-
ports 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. Un-
sharpened or improperly set blades pro-

duce narrow kerf causing excessive friction,
blade binding and kickback.
f. Blade depth and bevel adjusting locking le-
vers must be tight and secure before mak-
ing cut. If blade adjustment shifts while cut-
ting, it may cause binding and kickback.
g. Use extra caution when sawing into exist-
ing walls or other blind areas. The protrud-
ing blade may cut objects that can cause
kickback.
3. Lower Guard Function
a. Check the lower guard for proper closing
before each use. Do not operate the saw if
the lower guard does not move freely and
close instantly. Never clamp or tie the low-
er guard into the open position. If the saw
is accidentally dropped, the 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 slug-
gishly due to damaged parts, gummy depos-
its, or a buildup of debris.
c. The lower guard may be retracted manu-
ally only for special cuts such as "plunge
cuts" and "compound cuts". Raise the
lower guard by the retracting handle and
as soon as the blade enters the material,
the lower guard must be released. For all
other sawing, the lower guard should oper-
ate 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.
