19. Cutting discs must not be subjected to any
lateral pressure.
20. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
21. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the workpiece. Otherwise, it may
cause an electric shock, electrical leakage or gas
leak.
22. If a blotter is attached to the wheel, do not
remove it. The diameter of the blotter must be
larger than the lock nut, outer flange, and inner
flange.
23. Before installing a grinding wheel, always
check that the blotter part does not have any
abnormalities such as chips or cracks.
24. Tighten the lock nut properly. Overtightening
the wheel can cause breakage and insufficient
tightening can cause fluttering.
