Saw Blade Mounting And Dismounting - Hitachi C 10FCH2 Instruction Manual

Cutting method of crown molding without tilting the saw blade.
(1) Crown molding Stopper (L) and (R) (optional accessories) allow easier
cuts of crown molding without tilting the saw blade. Install them in
the base both-sides side to be shown in Fig. 30-a. After inserting
Tighten the 6mm knob bolts to secure the crown molding Stoppers.
[Optional accessories used]
• Crown molding Vise Ass'y (Include Crown molding Stopper (L))

(2) The crown molding vise (B) (Optional accessory) can be mounted
on either the left fence (Fence (B)) or the right fence (Fence (A)). It
can unite with the slope of the crown molding and vice can be pressed
down.
Then turn the upper knob, as necessary, to securely attach the crown
molding in position. To raise or lower the vise assembly, first loosen
the 6mm knob bolt.
After adjusting the height, firmly tighten the 6mm wing bolt; then
turn the upper knob, as necessary, to securely attach the crown
molding in position. (See Fig. 30-b)

WARNING:
Always firmly clamp or vise to secure the crown molding to the
fence; otherwise the crown molding might be thrust from the table
and cause bodily harm.
Do not bevel cutting. The main body or saw blade may contact the
sub fence, resulting in an injury.
CAUTION:
Always confirm that the motor head (see Fig. 1) does not contact
the crown molding vise ass'y when it is lowered for cutting. If there
is any danger that it may do so, loosen the 6mm knob bolt and
move the crown molding vise ass'y to a position where it will not
contact the saw blade.
Position crown molding with its WALL CONTACT EDGE against the
guide fence and its CEILING CONTACT EDGE against the crown
molding Stoppers as shown in Fig. 30-b.
Adjust the crown molding Stoppers according to the size of the crown
molding.
Tighten the 6mm wing bolt to secure the crown molding Stoppers.

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 inefficient cutting and
possible overload of the motor.
When cutting such materials, use a wood plate to protect the
workpiece as shown in Fig. 31-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 fine finish.
In addition, in case of a U-shaped workpiece, use the wood plate as
shown in Fig. 31-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. 32.

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 sufficiently
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
10mm box wrench (standard accessory), excessive or improperly
tightening occurs, resulting in injury.
