Investigate and take corrective actions to eliminate the cause of
blade binding.
When restarting a saw in the work-piece, center 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.
Support large panels to minimize 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.
Do not use dull or damaged blades. Unsharpened or improperly
set blades product narrow kerf causing excessive friction, blade
binding and kickback.
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.
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.

Safety instruction for circular

saw with lower guard

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 parts, in all
angles and depths of cut.
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.
Lower guard should 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.
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 blade to
stop after switch is released.
