GRINDING WHEEL SAFETY

• 

Ensure that the grinding wheel is correctly mounted 

and tightened before use.

• 

Operate the grinder at “no load” for 30 seconds in 

a safe position and ensure there is no vibration or 

other defects detected. If considerable vibration or 

other defects are detected, stop operation of the tool 

immediately and determine the cause. Do not use 

the tool until the defect is corrected.

• 

If the grinder is dropped with an abrasive wheel 

installed, the abrasive wheel should be examined 

thoroughly before use.

• 

Only use abrasive wheels that comply with ANSI 

B7.1/ISO 525, 603.

• 

Check that the maximum rpm operating speed of 

the abrasive wheel is equal to or greater than the 

rated shaft speed of the grinder.

• 

Ensure that the grinding wheel dimensions are com-

patible with the grinder and that the grinding wheel 

fits the shaft.

• 

Ensure that the thread type and size of the grinding 

wheel exactly matches the thread type and size of 

the shaft.
