Safety Instructions For Saws With Inner Pendulum Guard - Hitachi C 18DSL 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 fl oor.
