a)
Maintain a firm grip with both hands on the saw and position your arms to
resist kickback 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 controlled by the operator, if proper precautions are
taken.
b)
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.
c)
When restarting a saw in the work-piece, centre 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 work-piece 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 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.
Lower guard function
a) Check lower guard for proper closing before each use. Do not operate the
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
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 sluggishly due to damaged parts, gummy deposits, or a
build-up of debris.
c) Lower guard may be retracted manually only for special cuts such as
"plunge cuts" and "compound cuts". Raise lower guard by retracting handle
and as soon as 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
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.
