Practical Applications - Hitachi C 8FS Instrucciones De Manejo

English
(1) Use the 8 mm depth adjustment bolt on the gear case
for adjustments. Turning the 8 mm depth adjustment
bolt to the left increases the cutting depth (Fig. 2).
CAUTION
Ensure the height is adjusted securely so that the saw
blade does not contact the turntable.

PRACTICAL APPLICATIONS

CAUTION
It is dangerous to remove or install the wrokpiece
while the saw blade is turning.
When sawing, clean off the shavings from the
turntable.
If the shavings accumulate too much, the saw blad
from the cutting material will be exposed. Never
subject your hand or anything else to go near the
exposed blade.
1. Tightly secure the material by vise assembly to be
cut so that it does not move during cutting.
2. Switch operation.
Pulling the trigger turns the switch on. Releasing the
trigger turns the switch off.
3. Base holder adjustment (Fig. 9).
Loosen the 6 mm bolt with the supplied 10 mm box
wrench. Adjust the base holder until its bottom surface
contacts the bench or the floor surface.
4. Cutting a groove on the guard.
Holder (A) has a guard (see Fig. 1) into which a groove
must be cut. Loosen the 8 mm knob bolt to retract the
guard slightly.
After placing a suitable wooden piece to sit on the
fence and the table surfaces, fix it with the vise. After
the switch has been turned on and the saw blade has
reached maximum speed, slowly lower the handle to
cut a groove on the guard.
CAUTION
Do not cut the groove too quickly; otherwise the guard
might become damaged.
5. Adjusting the guard (Fig. 3).
(1) In the case of cutting at a right angle or bevel cutting:
Loosen the 8 mm knob bolt, bring the guard lightly in
contact with the materials to be cut and secure. Align
the ink line with the saw blade groove on the guard
and begin operations.
(2) In the case of miter cutting or miter cutting plus bevel
cutting.
Loosen the 8 mm knob bolt, move the guard to the
back, making sure that it is not sticking out from the
fence surface.
6. Cutting operation
(1) After turning on the switch and checking that the saw
blade is rotating at maximum speed, slowly push
down the handle while holding down the lever and
bring the equipment in the vicinity of the material to
be cut.
(2) When the saw blade contacts the workpiece, push the
handle down gradually to produce cutting.
(3) When the cutting (or desired cutting-in) has been
completed, raise the handle up to the retract position.
(4) Turn the tool OFF after each cutting operation is
completed, and allow the saw blade to come to a
complete stop before preparing for the next operation.
7
CAUTION
Increased pressure on the handle does not
necessarily mean faster cutting of the workpiece.
On the contrary, too much force may result in
overload of the motor and/or decreased cutting
efficiency.
Ensure the switch is turned OFF and the plug is
removed from the power outlet when work has
been completed.
7. Miter cutting procedure (Fig. 4).
(1) Loosen the side handle and adjust the turntable until
the indicator aligns with the desired setting on the
miter scale.
(2) Re-tighten the side handle to secure the turntable in
the desired position.
(3) The miter scale indicates both the cutting angle on
the angle scale and the gradient on the grade scale.
(4) The gradient angle fellows the ratio of the vertical
height versus the bottom length of the workpiece.
(5) Therefore, to cut a workpiece at a grade of 2/10, set
the indicator to position 2/10.
NOTE
Positive stops are at right and left angles 0˚, 15˚,
22.5˚, 30˚, and 45˚ to the center.
Check that the miter scale and the tip of the
indicator are properly aligned.
Operation of the saw with the miter scale and
indicator out of alignment, or with the side handle
not properly tightened, will result in poor cutting
precision.
8. Bevel cutting procedure (Fig. 5).
(1) Loosen the clamp lever and bevel the saw blade to
the left.
(2) Adjust the bevel angle to the desired setting while
watching the scale and indicator, then secure the
clamp lever.
(3) Perform cutting as deseribed in 5.
CAUTION
During an bevel cut, it will create a condition where
the piece cut off will come to rest on the saw blade.
If the handle is raised while the saw blade is still
rotating, the cut-off piece may become jammed
against the saw blade causing fragments to scatter
about dangerously.
9. Compound cutting
Compound cutting can be performed by following the
instructions in 7 and 8 above. At a bevel of 45° and a
miter angle of 45°.
WARNING
Always secure the workpiece with the right hand
side for compound cutting.
Never rotate the turntable to the right for
compound cutting, because the saw blade might
then contact the clamp or vise that secures the
workpiece, and cause personal injury or damage.
10. Cutting long materials
When cutting long materials, use an auxiliary platform
which is the same height as the holder and base of
the special auxiliary equipment. Insert the holder in
the hole on the right and left side of the base and
secure (Fig. 6).
Adjust the holder upon inserting so that it is the same
height as the base (Fig. 8).
After adjusting the height of the holder use the
securing knob bolt to secure the holder.
