APPLICATION
Cutting of various metallic materials such as pipes, round bars and shaped steel and siding board.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power requirements specified
on the product nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle
while the power switch is in the ON position, the power tool will start operating immediately,
which could cause a serious accident.
3. Extension cord
When the work area is removed from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.
4. Install the machine on a level flat place, and keep it in a stable condition. Prior to shipping,
the equipment is subjected to a rigid factory inspection to prevent electric shocks during
operation.
5. Since movable portions are secured by tension of a chain while in transit, remove the chain
from the chain hook by slightly depressing the switch handle.
6. Ascertain that all cut-offwheels are in perfect condition, and do not display scars and
cracks.
7. Although they have been fully clamped at the factory prior to delivery, reclamp the clamping
nuts securely for safety.
8. Possible accidents such as a cracked cut-offwheel is prevented by this protective cover
(wheel cover). Although it has been fully clamped at the factory prior to delivery, securely
reclamp the mounting screws for safety.
9. When replacing the cut-offwheel, ensure that the replacement cutting wheel has a
designed circumferential speed in excess of 4800 m/min.
10. Ensure that the bar spanner used for tightening or removing the cut-offwheel is not
attached to the machine.
11. Ensure that the material is securely fastened with the vise. If it is not, a serious accident
could be caused if the material comes loose or the cut-offwheel breaks during operation.
12. Continued cutting without noticing a cracked or split cut-offwheel may prove to be very
hazardous. Before starting operation, make a trial run to confirm that no abnormalities are
involved.
Trial run periods:
When replacing the cut-offwheel ........... Over 3 minutes.
When starting routine work ..................... Over 1 minute.
13. Rotate the cut-offwheel to inspect any facial deflection. A heavy deflection will cause the
cut-offwheel to shift.

CUTTING PROCEDURES
CAUTION
It is dangerous to remove or install the workpiece while the cut-offwheel turning.
1. Operating the switch
The switch is switched on by manually pulling the trigger and cut offby releasing the trigger
to the original location. The switch can operate continuously, even after releasing the
trigger, by pushing the stopper after pulling the trigger. The stopper can be removed by
pulling the trigger again and the switch is cut offwith the release of the trigger.
2. Cutting
(1) Rotate the cut-offwheel, gently press down the handle, and bring the cut-offwheel close to
the cutting material.
(2) When the cut-offwheel 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-offwheel (Fig. 2)
(1) Press the stopper and loosen the bolt with a
hex. bar wrench.
CAUTION
When the mounting shaft for cut-offwheel
cannot be fixed with pressing the stopper,
turn the bolt with a hex. bar wrench while
pressing the stopper. The mounting shaft
for cut-offwheel is fixed when the stopper
has been lowered.
(2) Remove the bolt, washer (A), and the wheel washer and detach the cut-offwheel.
2. Mounting the cut-offwheel
Throughly remove dust from the wheel washers and bolt then mount the wheel by following
the dismounting procedures in reverse order.

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. 3 and 4)
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. 3.
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. 4.
CAUTION
Never remove or install a workpiece
material while the cut-offwheel is
rotating, to avoid personal injury.
2. Cutting at angles (Fig. 5 and 6)
(1) The machine permits cutting at
angles of 45° or 60°.
(2) Loosen the two M10 hexagon
socket head bolts on the vise (B),
then set the working surface on the
vise-jaw at any angles of 0°, 30°,
or 45° as shown in Fig. 6. Upon
completion of setting, securely
tighten the two M10 hexagon socket
head bolts.

(3) When wide material is cut with angle, it will
be firmly camped by fixing a steel board
like Fig. 7 to the vise (B).
3. Moving the stationary vise-jaw (Fig. 8)
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. 9)
When the cut-offwheel 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-offwheel economically.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch offand pull offthe plug from the power outlet before inspection
and maintenance.
1. Replacing a cut-offwheel
When the cut-offwheel has already become dull while continually using, the unnecessary
load is got from the motor. Consequently, redress or replace a dull cut-offwheel 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 on page 15)
Oil supply points
○ Rotary part of shaft
○ Rotary part of vise
○ Slide way of vise (A)
