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 workpiece, 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 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 cut.
If blade adjustment shifts while cutting, it may cause binding
and kickback.
g) Use extra caution when making a "plunge cut" into existing walls or other
blind areas.
The protruding blade may cut objects that can cause kickback.
h) 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.
i)
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.
j)
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.
k) 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.
l)
Recommendation for the use of a residual current device
with a rated residual
current device of 30mA or less.
