When OFF button is pushed, 

the wheels may take a few moments to 
completely stop. 

The grinder will automatically shut off after 10 
minutes of inactivity. 

Note: After extended operation, the grinder 
housing may be warm to the touch. This is not 
abnormal.

  Precautions 

7.2.1

  Wheel grinding 

1.  Before starting grinder, turn grinding wheel by 

hand to verify that it is clear of obstruction and 
turns freely. The tool rest and spark guard 
should not touch the wheel. 

2.  Keep tool rest and spark guard to within 1/16" 

of grinding wheel. 

3.  Turn on grinder and allow it to reach full 

running speed before starting to grind. 

4.  Adjust the eye shield as needed. 

5.  Keep a steady, moderate pressure on the 

workpiece and keep it moving at an even pace 
for smooth grinding. Pressing too hard 
overheats the motor and prematurely wears 
the grinding wheel. Note the original bevel 
angle on the item to be sharpened and try to 
maintain the same shape. The grinding wheel 
should rotate into the object being sharpened. 

6.  If grinding a narrow workpiece, slide it laterally 

across width of wheel. Using full width of 
wheel will help prevent a groove from forming 
at one place on the wheel. 

7.  Keep a water pot filled with water and dip your 

work into it regularly to prevent overheating. 
Overheating can weaken metals. Do not apply 
water directly to grinding wheel. 

8.  Do not use the side of the grinding wheel; this 

puts dangerous stress on the wheel. 

9.  When wheel becomes loaded or dull, use an 

approved grinding wheel dresser and dress 
the wheel face. 

7.2.2

  Belt and Disc grinding 

1.  Remove belt before grinding on disc, to 

prevent accidental contact of hands with belt. 

2.  Always grind on downward side of disc. 

Grinding on upward side may cause workpiece 
to catch and slip from your grasp. 

3.  At all times, keep hands and fingers away from 

pinch points while grinding in disc or belt area.
