MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS
6.6 CHANGING THE SEALING FELT ON THE COVER
OF THE SANDING DISC GEAR
Only use original LÄGLER sealing felts (order no. in
Section 11,
Spare parts
).
If the sealing felt on the cover of the sanding disc gear shows signs
of wear and tear, it must be replaced. This can be recognized by
visual inspection, e.g. while changing sanding discs. Too much wear
in the area of the sanding disc gears allows dust to drift into your
drive unit, increasing the abrasion of the tooth belt.
Please proceed as follows:
1
Switch off the machine.
2
Disconnect power supply before commencing any work on
the machine; this will prevent inadvertent motor action!
3
Release the clamping lever of the handle, press handle for-
ward and pull the clamping lever back into its prior position
(Fig. 51).
4
While holding on to the handle, carefully tilt the machine back-
wards into a horizontal position. Make sure that the machine
gets to rest safely on the guide tube and the two protective
cushions (Fig. 52).
Make sure the machine is in a safe posi-
tion!
5
Remove the sanding discs or brushes. To do this, grasp the
gear edges with your fingers and pull the gear out of the rub-
ber jig (Fig. 53).
6
Loosen all eight cover screws and take the cover off
(Fig. 54).
7
Pull the worn sealing felt off the inside of the cover and remove
all residue adhesive.
8
Pull part of the protection paper off the new sealing felt, about
a hand wide and position the seal exactly. Use the fixing holes
in the cover for alignment (Fig. 55).

Then remove the eight screws and pull off the
cover.

Grasp the gear edges with your fingers and pull
it out of the rubber jigs.

Carefully tilt the machine backwards to be able
to access the gears.
Make sure the machine is
in a safe position!
