OPERATION
WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forc-
ing 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.
