Specific Safety Rules And Symbols - Hitachi Koki C 7UR Mode D'emploi

English
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 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.
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.
Electric brake
For model C7BUR, this tool is equipped with an
electric brake which will typically stop the blade within
7 seconds after the trigger switch is released.
Occasionally, there will be a delay in the brake
engaging which will result in a longer blade stopping
time. On rare occasions, the brake may not engage at
all and the saw blade will coast to a stop.
If the brake fails to engage frequently, depress and
release the trigger switch to turn the tool on and off 4
or 5 times.
If the brake still does not engage, replace the brushes
and try the saw again.
If the brake still does not engage, have the tool
serviced at a Hitachi authorized service center.
Always confi rm that the saw blade has completely
stopped before raising it from the workpiece.
The brake is not a substitute for a properly functioning
lower guard. Check the function of the lower guard
before each use.
Serious personal injury may occur if the lower guard
does not move smoothly and cover the blade properly.

SPECIFIC SAFETY RULES AND SYMBOLS

1. Adjustments. Before cutting be sure depth and
bevel adjustments are tight.
2. Avoid cutting nails. Inspect for and remove all
nails from work piece before cutting.
3. When operating the saw, keep the cord away
from the cutting area and position it so that it
will not be caught on the workpiece during the
cutting operation.
Operate with proper hand support, proper workpiece
support, and supply cord routing away from the work
area.
WARNING:
It is important to support the work piece properly and
to hold the saw fi rmly to prevent loss of control which
could cause personal injury. Fig. 1 illustrates typical
hand support of the saw.

HAND SUPPORT WORKPIECE SUPPORT,
AND SUPPLY CORD ROUTING.
4. Place the wider portion of the saw base on that
part of the work piece which is solidly supported,
not on the section that will fall off when the cut is
made.
As examples, Fig. 2 illustrates the RIGHT way to cut
off the end of board, and Fig. 3 the WRONG way. If the
work piece is short or small, clamp it down.
DON'T TRY TO HOLD SHORT PLACES BY HAND!
