M1107 Bench grinder

MAINTENANCE

Check for the following conditions and repair or

replace when necessary:

• Cracked or loose grinding wheel.

• Loose mounting bolts.

• Worn switch.

• Worn or damaged cords and plugs.

• Any other condition that could hamper the safe

operation of this machine.

This grinder has sealed bearings that require no user

lubrication.

The grinding wheel should be inspected before every

use. Use the ring test method noted in

Changing

Grinding Wheels

on Page 13 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 wheel diameter is reduced

to 4". Operating at anything less than this diameter does

not allow the proper surface speed for grinding or spac

ing of the tool rest and the eye shield, and the grinding

wheel may fly apart.

Depending on the type of grinding you do, the grinding

wheel may require periodic dressing. There are several

different types of wheel dressing devices available on

the market. Use a suitable diamond or silicon carbide

stick type dresser. Sweep it smoothly and evenly several

times across the face of the wheel. Dressing restores the

abrasive quality of the wheel surface, plus it will bring

the wheel edge back to a square form. Refer to the

instructions that accompany your dressing accessory for

complete detail on wheel dressing.
