Cutting off the following materials:
• Round bars • Various types of shaped steel
• Siding boards up to 240 mm and so on.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
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.
5. Confirming condition of the environment
Confirm that the work site is placed under
appropriate conditions confirming to prescribed
6. Take off the chain
As the movable parts is pulled down by a chain
when shipping out, please slightly push the handle
down and take off the chain from handle.
7. Clean and check the work place
Check the work place whether it is in a proper
condition as mentioned in the cautions.
8. Ascertain that all cut-off wheels are in perfect
condition, and do not display scars and cracks.

9. Although they have been fully clamped at the factory
prior to delivery, reclamp the clamping bolt securely
for safety (See the item on Replacing the cut-off
10. Possible accidents such as a cracked cut-off wheel
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.
Confirm that the protective cover (wheel cover) is
11. When replacing the cut-off wheel, ensure that the
replacement cut-off wheel has a designed
circumferential speed in excess of 4800 m/min.
12. Confirm the stopper
Confirm that the stopper which was used for
installation and removal of the cut-off wheel has
returned to the retract position.
13. 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-off
wheel breaks during operation.
14. Confirm the power supply
If the power receptacle only loosely accepts the
plug, the receptacle must be repaired. Contact the
nearest electric store for repair service.
If such a faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
15. Continued cutting without noticing a cracked or
split cut-off wheel 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-off wheel
When starting routine work
16. Inspect facial deflection of the Cut-off wheel
Rotate the Cut-off wheel to inspect any facial
deflection. A heavy deflection will cause the Cut-
off wheel to shift.
