MAINTENANCE

Schedule

Grinding Wheels

The grinding wheels should be inspected before every

use. Use the ring test method noted in Wheel Inspection

on Page 21 to verify the structural integrity. Take care in

storing grinding wheels to keep them free from potential

damage by being dropped or having other items drop on

them. Replace the wheel when the spark deflector or tool

rest has no more adjustment and the gap has exceeded

the safe limit.

Cleaning & Protecting

Cleaning the grinder is relatively easy. Vacuum excess

debris, and wipe off the remaining dust with a dry cloth.

Wheel Storage

Grinding wheels can be easily damaged, so it is important

to store them properly. Follow all wheel manufacturer

storage instructions. Always store grinding wheels in a

location that is dry and protected from potential damage

due to them being dropped or having other items dropped

on them. Also, avoid storing grinding wheels where there

is high humidity, extreme heat or cold, or solvents.

MAKE SURE that your machine is

unplugged during all maintenance pro-

cedures! If this warning is ignored, seri-

ous personal injury may occur.

Wheel Dressing

Depending on the type of grinding you do, the grinding

wheel may require periodic dressing. Dressing restores the

abrasive quality of the wheel surface and squares up the

wheel edge. Refer to the instructions that accompany your

dressing accessory for complete details on how to properly

dress a wheel.
