required to loosen it. Insert one pin of the wrench into a
hole and turn Ezynut counterclockwise.

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.
Grinding and sanding operation (Fig. 16)
ALWAYS hold the tool firmly with one hand on rear handle
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been rounded
off by use, the wheel may be worked in both A and B
direction.
