CLEANING AND CARE INSTRUCTIONS
6.1.1 THE DRIVE UNIT
The drive unit should be removed and cleaned at least once a week
if the machine is used every day. The drive unit is removed using
the following procedure:
1
Switch the machine off and pull the mains plug out of the
socket!
2
Ensure that the sanding drum is raised off the floor.
3
Release the cover lock and remove the side cover on the right
of the machine housing (Fig. 26).
4
Pull the opposite operating lever for the drive unit upwards.
This lowers the tensioning roller (Fig. 26).
5
Remove the abrasive belt (Fig. 27).
6
If you wish to remove the tensioning roller of the drive unit
(Section 6.6.2, Exchanging the tensioning roller)
, press the
operating lever for the drive unit downwards (Fig. 14).
7
Remove the operating lever by unscrewing (Fig. 28).
8
Release and remove the three hexagonal socket head screws
(Fig. 29).
9
Carefully remove the unit and clean it (Fig. 30).
Reassemble in reverse order. After mounting the drive unit, check
the belt tracking and set if required
(Section 6.3, Checking sanding
belt regulation).
Regular exchange of the sanding drum and tensioning roller guar-
antees a constant degree of operating quality and performance.
When working every day with the machine, they must be exchanged
every 1 - 2 years, otherwise every 3 – 4 years (see
Section 6.6.1
and 6.6.2).
