Checking the machine

6.8.1 Abrasive and grinding spindle

WARNING

Risk of injury!

Abrasives whose use-by date has expired or

abrasives with dents or cracks can burst dur-ing

operation! Fragments can fly everywhere and

cause serious injuries.

►

Do not use abrasives whose use-by dates

have expired.

►

Use only abrasives which are free from

dents or cracks.

►

Do not use abrasives if they run out-of-true.

CAUTION

Risk of injury!

If unbalanced abrasives are used, the values

for hand-arm vibration will be exceeded.

►

Do not use abrasives with an unbalance in

excess of 2 m/s

.

1. Check the abrasive pad for tightness.
2. Perform the following checks:

Visual inspection

•

Check the abrasive pads for cracks or other damage (frac-

tures and adequate height).

•

Check safety devices for correct seating and integrity.

•

Check the drive V-belt of the abrasive wheel for

integrity and adequate tensioning.

Functional checks

•

Check the handwheel resistance setting (should be moder-

ately hard to turn by hand).

•

Check the integrity and free movement of the tilt

adjust-ment.
