Safety Instructions For Saws With Inner Pendulum Guard - Hitachi C 9U2 Handling Instructions Manual

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 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.
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.
SAFETY INSTRUCTIONS FOR SAWS WITH INNER
PENDULUM GUARD
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 depth 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 build-up of
debris.
c) 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.
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.
