Changing Grinding Wheel

Tools Needed

Qty

Wrench 10mm ................................................... 1

To change the grinding wheel:

1. DISCONNECT GRINDER FROM POWER!

2. Use the wrench on the left-hand side of the

motor  arbor  to  keep  it  from  turning,  then
rotate  the  grinding  wheel  counterclockwise
to  remove  it  from  the  arbor,  as  shown  in

Figure 17.

3. Store the grinding wheel in a safe, dry loca-

tion that is not exposed to extreme tempera-
tures.

4. Visually check the replacement wheel for

cracks, soft spots, excessive wear, or any
other damage—if you are not sure about the
condition of the wheel, DO NOT use it!

5. Thread the wheel onto the motor arbor and

only hand-tighten it.

Note:

The force of the bit against the coun-

terclockwise rotation of the wheel will keep it
safely on the arbor.

the drill bit diameter.

To avoid serious personal injury from flying

wheel or drill bit debris, ALWAYS use the

correct grinding wheel diameter for the size

of the drill bit.
