Cleaning the dust scrabbers of the telescopic fork
The dust-protection bellows 1 are to remove dust and coarse dirt particles
from the fork tube. However, after some time, dirt may also get in behind
the dust-protection bellows. If this dirt is not removed, the oil sealing rings
located behind it may start to leak.
For this purpose, use a screwdriver to lift the dust scrabbers out of the
slider tubes, clean them thoroughly with compressed air, spray the fork
tubes and dust scrabbers with silicon oil and press the scrabbers back into
the slider tubes.
Changing spring preloading of the shock absorber
This is easily done.
NOTE: Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
Remove the right side cover.
Loosen the locking ring
2 with the hook spanner. Change the spring preload
with the adjusting ring 3 and re-tighten the locking ring 2 .
BASIC SETTING – SPRING PRELOAD

10 mm (0.4 in).
If necessary, correct chain tension.

that the supporting plates
6 are resting against the swing arm. Additionally,
check that the rear wheel is aligned with the front wheel.
