Saw Blade Mounting And Dismounting - Hitachi C 10FCG Safety Instructions And Instruction Manual

8. Cutting easily-deformed materials, such as aluminum sash
Materials such as aluminum sash can easily deform when tightened too
much in a vise assembly. This will cause ineffi cient cutting and possible
overload of the motor.
When cutting such materials, use a wood plate to protect the workpiece
as shown in Fig. 25-a. Set the wood plate near the cutting section.
When cutting aluminum materials, coat the saw blade with cutting oil
(non-combustible) to achieve smooth cutting and a fi ne fi nish.
In addition, in case of a U-shaped workpiece, use the wood plate as
shown in Fig. 25-b to ensure stability in the lateral direction, and clamp
it near the cutting section of the workpiece and tighten it using both the
vise assembly and the clamp available in the market.

9. How to use the dust bag (Standard accessory)
(1) When the dust bag has become full of sawdust, dust will be blown out of
the dust bag when the saw blade rotates.
Check the dust bag periodically and empty it before it becomes full.
(2) During bevel and compound cutting, attach the dust bag at a right angle
to the base surface as shown in Fig. 26.

CAUTION:
Empty the dust bag frequently to prevent the duct and the safety
cover from becoming clogged.
Sawdust will accumulate more quickly than normal during bevel
cutting.

SAW BLADE MOUNTING AND DISMOUNTING

WARNING:
∗ To prevent an accident or personal injury, always turn off
the trigger switch and disconnect the power plug from the
receptacle before removing or installing a saw blade.
If cutting work is done in a state where the bolt is not suffi ciently
tightened, the bolt can get loose, the blade can come off , and
the lower guard can get damaged, resulting in injuries.
Also, check that the bolts are properly tightened before plugging
the power plug into the receptacle.
∗ If the bolts are attached or detached using tools other than
the 5mm Hex. bar wrench (standard accessory), excessive or
improperly tightening occurs, resulting in injury.

1. Mounting the saw blade (Fig. 27-a, Fig. 27-b, Fig. 27-c and Fig. 27-d)
(1) Rotate the lower guard (plastic) to the top position.
(2) Use the driver to loosen the 4mm screw fastening the spindle cover and
then remove the spindle cover.
(3) Press in spindle lock and loosen bolt with 5mm Hex. bar wrench (standard
accessory).
Since the bolt is left-hand threaded, loosen by turning it to the right as
shown in Fig. 27-c.
NOTE:
If the spindle lock cannot be easily pressed in to lock the spindle,
turn the bolt with 5mm Hex. bar wrench (standard accessory) while
applying pressure on the spindle lock.
The saw blade spindle is locked when the spindle lock is pressed
inward.
(4) Remove the bolt, washer (D) and washer (E)

(5) Lift the lower guard and mount the saw blade.
WARNING:
When mounting the saw blade, confi rm that the rotation indicator
mark on the saw blade and the rotation direction of the gear case
(see Fig. 1) are properly matched.
(6) Thoroughly clean washer (D), washer (E) and the bolt, and install them
onto the saw blade spindle.
