INSTRUCTIONS FOR OPERATION

Stop Screw

Stop screw is used to prevent cut-off wheel

from contacting with worktable or ground.

When installing the cut-off wheel, set the

stop screw at a higher position. When the

wheel is worn to less than 330 mm in

diameter, set the stopper at lower position

so that the servicing life of the machine can

be prolonged. (Fig. 1)

Interval between Vise Plate and Guide Plate

The original spacing or interval between the vise plate and the guide plate is 0-170mm.

If your work requires wider spacing or

interval, proceed as follows to change the

spacing or interval.

Remove the two hex bolts which secure the

guide plate. Move the guide plate as the

direction of arrow shown in the right figure

and secure it by tightening the two hex bolts.

Then the space or interval can be set

between 35 to 205 mm or between 70 to 240

mm. But under such circumstance, fixity of

the workpiece turns bad relatively. (Fig. 7)
