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:
Never switch on the tool when it is in contact with
•
the workpiece, it may cause an injury to operator.
Always wear safety goggles or a face shield during
•
operation.
After operation, always switch off the tool and wait
•
until the wheel has come to a complete stop before
putting the tool down.
