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 specifi ed
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 suffi cient
thickness and rated capacity. The extension cord should be kept as short as practicable.
4. Install the machine on a level fl at 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-off wheels 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-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.
9. When replacing the cut-off wheel, 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-off wheel 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-off wheel breaks during operation.
12. 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 confi rm that no abnormalities are
involved.
Trial run periods:
When replacing the cut-off wheel ........... Over 3 minutes.
When starting routine work ..................... Over 1 minute.
13. Rotate the cut-off wheel to inspect any facial defl ection. A heavy defl ection will cause the
cut-off wheel to shift.
