8. Maintenance and Cleaning

Clean, check and perform maintenance work on the
machine and guard devices regularly. Regularly
clean the inside of the grinding wheels and belt
grinder housing. The grinding wheels and sanding
belt must be able to rotate freely within the housing.
Disconnect the mains plug before starting any
setting, cleaning, maintenance or repair work.
8.1 Sanding disc change
Use only original Metabo sanding discs.
The permissible rotational speed specified on
the sanding disc must be equal to or greater
than the maximum idling speed specified on the
identification plate of the machine.
Sanding disc check:
suspend the sanding disc on a thread. Knock
lightly with a piece of hard wood. You will hear a
clear tone if the sanding disc is in perfect condition.
If you hear a clattering, dull or hollow sound, the
grinding wheel is damaged.
Do not use damaged sanding discs.
Test run
A test run of approx. 5 min without load must
be carried out after the grinding wheel has been
changed. All persons must stay clear of the danger
zone when this is performed.
Sanding disc:
- Remove screws from safety cover (1) and take off
cover (1).
- Hold the sanding disc (4) firmly in position as
shown. Caution! Risk of injury! Wear
protective gloves!
- Remove adjusting nut (2) with an open-ended
spanner.
Caution! Left-hand thread on left machine
side, i.e. to release the adjusting nut (2) on the left
machine side, turn clockwise!
- Remove clamping flange (3) and sanding disc (4).
- Secure new sanding disc (4) in the reverse order.
- Remount the safety cover (1). Tighten the screws.

Remove the side sanding belt cover (18): release
the 2 screws (16), slide the sanding belt cover (18)
(bayonet catch) and remove.
Swivel out lever (15) as far as it will go. This relieves
sanding belt tension and it can now be removed
from the rollers.
Place the new sanding belt on the rollers so that its
direction of circulation (arrows on the inside of the
sanding belt) matches the arrow (19) on the side
sanding belt cover (18).
Return the lever (15) to the original position to
tension the sanding belt.
Place the side sanding belt cover (18) on the 2
screws (16) and slide (bayonet catch). Tighten the
