2. Power switch
Ensure that the power switch is in the OFF position. If the plug is connected to a power
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. Check that the work piece is properly supported.
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. Ensure that the abrasive wheel is correctly fitted and tightened before use and run
the machine at no-load for 30 seconds in safe position, stop immediately if there is a
considerable vibration or if other defects are detected. If this condition occurs, check the
machine to determine the cause.
13. Rotate the cut-offwheel to inspect any facial deflection. A heavy deflection will cause the
cutoffwheel to shift.
14. Ensure that ventilation openings are kept clear when working in dusty conditions. If it
should become necessary to clear dust, first disconnect the machine from the mains
supply.

HOW TO OPERATE
1. Procedure for fixing the cutting material
(Fig. 5 and 6)
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. 5.
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 (A), and
remove the workpiece material, as shown
in Fig. 6.
