Precautions in use
Check for cracks in the depressed center wheel and for loose or missing screws.
Always use the guard. It can prevent an accident if a wheel should ever break.
Before using the disc grinder on an actual workpiece, let it simply run for several minutes
first. Watch for flutter that might be caused by poor installation or a poorly balanced
wheel.
Choose a wheel grade in terms of the workpiece material.
How
to use
Installing the depressed center wheel
Unplug the tool from the power source and
perform the following steps:
1. Place the depressed center wheel flange
on the spindle. (Fig. 1)
2. Fit the depressed center grinding wheel
