How To Operate; Maintenance And Inspection - HIKOKI CC 14SF Instrucciones De Manejo

English
(2) When the cut-off wheel contacts the cutting material,
gently press down the handle further and start
cutting.
(3) When cutting (or designated slotting) is completed,
raise the handle and restore it to its original position.
(4) At the termination of each cutting process, turn OFF
the switch to stop rotation and proceed with the
subsequent cutting job.
CAUTION
It does not necessarily cut rapidly when putting
more force on the handle.
Too much force on the handle will put excessive
pressure on the motor and reduce its capacity.
Do not fail to switch OFF the switch after operation
is completed and pull the plug out.
MOUNTING AND DISMOUNTING THE CUT-
OFF WHEEL
1. Dismounting the cut-off wheel (Fig. 2)
(1) Press the stopper and loosen the bolt with a hex.
bar wrench.
CAUTION
When the mounting shaft for cut-off wheel cannot
be fixed with pressing the stopper, turn the bolt
with a hex. bar wrench while pressing the stopper.
The mounting shaft for cut-off wheel is fixed when
the stopper has been lowered.
(2) Remove the bolt, washer (A), and the wheel washer
and detach the cut-off wheel.
2. Mounting the cut-off wheel
Throughly remove dust from the wheel washers
and bolt then mount the wheel by following the
dismounting procedures in reverse order. Be sure
to attach the sub-cover at the end.
CAUTION
Confirm that the stopper which was used for
installation and removal of the cut-off wheel has
returned to the retract position.

HOW TO OPERATE

1. Procedure for fixing the cutting material (Fig. 8
and 9)
Place the workpiece material between vise (A) and
vise (B), raise the clutch and push the screw handle
to bring vise (A) lightly into contact with the
workpiece material, as shown in Fig. 8.
Then, turn the clutch down, and securely fix the
workpiece material in position by turning the screw
handle. When the cutting job is completed, turn the
screw handle 2 or 3 times to loosen the vise, and
remove the workpiece material, as shown in
Fig. 9.
CAUTION
The wheel continues to rotate after the machine is
switched off.
Never remove or install a workpiece material while
the cut-off wheel is rotating, to avoid personal injury.
Long workpieces must be supported by blocks
nonflammable material on either side so that it be
level with the base top.
2. Cutting at angles (Fig. 3 and 4)
(1) The machine permits cutting at angles of 45° or 60°.

(2) Loosen the two M10 hexagon socket head bolts on
the vice (B), then set the working surface on the
vice-jaw at any angles of 0°, 30°, or 45° as shown
in Fig. 4. Upon completion of setting, securely tighten
the two 10 mm bolts.
(3) When wide material is cut with angle, it will be
firmly camped by fixing a steel board like Fig. 5
to the vise (B).
3. Moving the stationary vise-jaw (Fig. 6)
The vise opening is set at the maximum of 170 mm
when shipped from the factory. In case an opening
of more than 170 mm is required, move the vise
to the position shown by the chain line after
unscrewing the two bolts. The maximum opening
can be set in two steps 205 mm and 240 mm. When
the cutting material is excessively wide, the vise can
be effectively used by repositioning the stationary
side of the vise-jaws.
4. How to use metallic block (Fig. 7)
When the cut-off wheel has a reduced outer
diameter, insert between the vise (A) and (B) a
metallic block slightly smaller than the dimension
of workpiece being cut to use the cut-off wheel
economically.

MAINTENANCE AND INSPECTION

CAUTION
Be sure to switch off and pull off the plug from the power
outlet before inspection and maintenance.
1. Replacing a cut-off wheel
When the cut-off wheel has already become dull
while continually using, the unnecessary load is got
from the motor. Consequently, redress or replace
a dull cut-off wheel to ensure grinding efficiency.
2. Inspecting the carbon brushes (Fig. 10)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or
near the "wear limit", it could result in motor trouble.
When an auto-stop carbon brush is equipped, the
motor will stop automatically. At that time, replace
both carbon brushes with new ones which have the
same carbon brush Number shown in the figure.
In addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
3. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
4. Lubrication
Supply oil in the following oil supply points once
a month so as to keep the machine workable for
a long time (See Fig. 1).
Oil supply points
Rotary part of shaft
Rotary part of vise
Slide way of vise (A)
5. Cleaning
Wipe off chip and waste adhered to the machine
with a cloth or the like time to time. Be careful not
to make the motor portion wet with oil or water.
6. Faults in the machine, including guards or cutter
blades, should be reported as soon as they are
discovered.
