Cutting Procedures; Mounting And Dismounting The Saw Blade - Hitachi C 9U2 Handling Instructions Manual

English

CUTTING PROCEDURES

1. Place the base on the material, then align
the premarked line and the sawblade
with the guide piece front scale section at
the front of the base (Fig. 8 on page 23).
When the base is not slanted, use the
large cutout as the guide (Fig. 8 on page
23 and Fig. 10 at right).
If the base is slanted (45 degrees), use
the small front scale as the guide (Fig. 8
on page 23 and Fig. 11 at right).
2. Ensure that the switch is turned to the ON
position before the saw blade comes in
contact with the lumber. The switch is turned
ON when the trigger is squeezed; and OFF
when the trigger is released.
3. Moving the saw straight at a constant speed
will produce optimum cutting.
CAUTION
Prior to cutting operation, make sure
the material you are going to cut. If
the material to be cut is expected to
generate harmful / toxic dusts, make
sure the dust bag or appropriate dust
extraction system is connected with dust outlet tightly.
Wear the dust mask additionally, if available.
Before starting to saw, ensure that the saw blade has reached full speed
○
revolution.
Should the saw blade be stopped or made an abnormal noise during
○
operation, turn off the switch immediately.
Always take care in preventing the power cord from coming near the
○
revolving saw blade.
Using the circular saw with the saw blade facing upwards or sideways is very
○
hazardous. Such uncommon applications should be avoided.
When cutting materials, always wear protective glasses.
○
When fi nished with a job, pull out the plug from the receptacle.
