SECTION 6: MAINTENANCE
!
Always DISCONNECT POWER before servicing, adjusting, or doing main- tenance to reduce the risk of acci- dental injury or electrocution.
For optimum performance from your machine, routinely check the condition of the following items and repair or replace as necessary:
•Cracked or loose grinding wheel.
•Loose hardware.
•Bent universal support.
•Worn switch.
•Worn or damaged cords and plugs.
•Any other condition that could hamper the safe operation of this machine.
Wheel Dressing
Depending on the type of grinding you do, the grinding wheel may require periodic dressing.
A variety of dressing tools are available (see Accessories, Page 18) and can be used to restore the abrasive quality of the wheel surface and bring the wheel edge back to a square form.
Refer to the instructions that accompany your dressing accessory for complete details on how to properly dress a wheel.

Grinding Wheels
The grinding wheel should be inspected before every use. Use the ring test method described in Wheel Inspection on Page 10 to verify the structural integrity of the wheel. Take care in storing grinding wheels to keep them free from potential damage from moisture, being dropped, or getting dropped on.
Wheel Replacement
To replace the grinding or stropping wheel:
1.. DISCONNECT GRINDER FROM POWER!
2.. Hold the wheel to keep it from turning and remove the arbor nut or knob that holds the wheel on.
3.. Remove the outer washer and wheel.
4.Install the new wheel, then replace the washer and nut or knob.
5.. Dress the wheel, if necessary.
Water Reservoir
Be sure to periodically empty, rinse and refill the water reservoir with clean water depending on frequency of use. Failing to do so can lead to a buildup of sediment on the wheel itself, reducing grinding per- formance.
