c ) When restarting a saw in the workpiece, centre the saw blade in the
kerf so that the saw teeth are not engaged into the material. If a saw
blade binds,it may walk up or kickback from the workpiece as the saw is
restarted.
d ) Support large panels to minimise the risk of blade pinching and
kickback. Large panels tend 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
e ) Do not use dull or damaged blades. Unsharpened or improperly set
blades produce narrow kerf causing excessive friction, blade binding and
kickback.
f ) Blade depth and bevel adjusting locking levers must be tight and
secure before making the cut. If blade adjustment shifts while cutting, it
may cause binding and kickback.
g ) Use extra caution when sawing into existing walls or other blind
areas. The protruding blade may cut objects that can cause kickback.

SAFETY INSTRUCTIONS FOR SAW
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
lower 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 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
sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c ) the lower guard may be retracted manually 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 operate automatically.
d ) Always observe that the lower guard is covering the blade before placing the 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.

ADDITIONAL SAFETY INSTRUCTIONS FOR ALL SAW WITH RIVING
KNIFE
Riving knife function
a ) Use the appropriate saw blade for the riving knife. For the riving knife
to function, the body of the blade must be thinner than the riving knife and
