OPERATION
WARNING:
•
It should never be necessary to force the tool. The
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.
•
NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
•
After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
