weight of the tool applies adequate pressure.
Forcing and excessive pressure could cause
dangerous wheel breakage.
ALWAYS replace wheel if tool is dropped while
•
grinding.
NEVER bang or hit grinding disc or wheel onto
•
work.
Avoid bouncing and snagging the wheel, especially
•
when working corners, sharp edges etc. This can
cause loss of control and kickback.
