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
ALWAYS hold the tool firmly with one hand on rear handle and the other on the
006741
side handle. Turn the tool on and then apply the wheel or disc to the work-
piece.
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.
CAUTION:
• Always be sure that the tool is switched off and unplugged before
attempting to perform inspection or maintenance.
The tool and its air vents have to be kept clean. Regularly clean the tool's air
006744
vents or whenever the vents start to become obstructed.
