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. 

• 

Continued use of a worn-out wheel may result in 
wheel explosion and serious personal injury. 
Depressed center wheel should not be used after it 
has been worn down to 75 mm in diameter. Use of 
the wheel after this point is unsafe and it should be 
removed from service and rendered unusable by 
intentional destruction.

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.
