Maintenance And Inspection - Hitachi C 10FCB Bedienungsanleitung

7. Bevel cutting procedure (Fig. 9)
(1) Loosen the clamp handle and bevel the saw blade to
the left.
(2) Adjust the bevel angle to the desired setting while
watching the bevel angle scale and indicator, then
secure the clamp lever.
WARNING
In the case of left bevel cutting, turn the sub fence
(Fig.1) counterclockwise. Unless it is turned
counterclockwise, the main body or saw blade may
contact the sab fence, resulting in an injury.
When the workpiece is secured on the left side of the
blade, the short cut-off portion will come to rest on
the right side of the saw blade. Always turn the power
off and let the saw blade stop completely before
raising the handle from the workpiece.
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.
8. Compound cutting procedure
Compound cutting can be performed by following the
instructions in 6 and 7 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.
9. Installing the holders (Optional accessory)(Fig. 4)
The holders help keep longer workpieces stable and
in place during the cutting operation.
(1) Use a steel square for aligning the upper edge of the
holders with the base surface.
(2) After aligning, secure the holders with the 6 mm wing
bolts.
CAUTION
When transporting or carrying the tool, do not grasp
the holder.
There is the danger of the holder slipping out of the
base. Grasp the handle instead of the holder.
10. Stopper (Optional accessory) for precision cutting
(Fig. 5.)
The stopper facilitates continuous precision cutting
in lengths of 255 mm to 420 mm. To install the stopper,
attach it to the holder with the 6 mm wing bolt.
MOUNTING AND DISMOUNTING SAW BLADE
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
blade.
1. Mounting the saw blade (Fig. 10, Fig. 11 and Fig. 12)
(1) Loosen the 6 mm wing bolt holding the spindle cover
by turning it left more than two turns.
(2) Rotate the spindle cover.
(3) Press in lock lever and loosen bolt with 10mm box
wrench.
Since the bolt is left-hand threaded, loosen by turning
it to the right.
NOTE
If the lock lever cannot be easily pressed in to lock the
spindle, turn the bolt with 10 mm box wrench while
applying pressure on the lock lever.
The saw blade spindle is locked when the lock lever
is pressed inward.
(4) Remove the bolt and washer (B)
(5) Lift the safety cover and mount the saw blade.
WARNING
When mounting the saw blade, confirm that the
rotation indicator mark on the saw blade and the
rotation direction of the gear case are properly
matched.
(6) Thoroughly clean washer (B), collar (A) and the bolt,
and install them onto the saw blade spindle.
(7) Press in the lock lever and tighten the bolt by turning
it to the left by 10mm box wrench.
(8) Rotate the spindle cover unitl hook in spindle cover
is in the original position. Then, tighten the 6 mm wing
bolt.
CAUTION
Confirm that the lock lever has returned to the retract
position after installing or removing the saw blade.
Tighten the bolt so it does not come loose during
operation.
Confirm that the bolt has been properly tightened
before the power tool is started.
Confirm that the safety cover has closed position.
2. Dismounting the saw blade
Dismount the saw blade by reversing the mounting
procedures described in paragraph 1 above.
The saw blade can easily be removed after lifting the
safety cover.
CAUTION
Never attempt to install saw blades except
235 mm – 255 mm in diameter and 2.1 mm - 2.7 mm
thickness.

MAINTENANCE AND INSPECTION

WARNING
To avoid an accident or personal injury, always
confirm the trigger switch is turned OFF and that the
power plug has been disconnected from the
receptacle before performing any maintenance or
inspection of this tool.
1. Inspecting the saw blade
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, re-tighten them immediately. Failure to do
so could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 13)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace a carbon
brush with a new one when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
4. Replacing a carbon brushes
Disassemble the brush cap with a minus-head
screwdriver. The carbon brushes can then be easily
removed.
