9.3 Servicing the travel and auger drives
(09)
WARNING! Risk of injury during mainte-
nance work. Improper maintenance can result in
serious injury and in damage to the appliance.
■
Adjust the Bowden cable only with the engine
switched off.
■
Stop the engine if the travel/auger drive can-
not be switched off.
■
Do not try to carry out repairs yourself and
contact a specialist workshop immediately.
NOTE Moisture in the Bowden cable can re-
sult in corrosion or freezing. A damaged Bowden
cable must be replaced.
Adjust Bowden cable
If the travel/auger drive cannot be engaged with
the engine running, the respective Bowden cable
must be adjusted.
1. Loosen lock nut (09/2).
2. Turn the adjuster on the Bowden cable (09/1)
in the direction of the arrow (09/a) until the
Bowden cable no longer sags (is slightly ten-
sioned). While turning the adjuster, hold the
cable so that it does not become twisted.
3. Tighten lock nut (09/2) (09/b).
4. To check the setting, start the engine and
switch on the travel/auger drive.
5. If the travel/auger drive still cannot be proper-
ly engaged, the appliance must be taken to a
specialist workshop.

can result in serious damage to the appliance!
1. Switch off the appliance and remove the
spark plug connector.
2. Remove the cotter pin (48/1) (48/a).
3. Pull out the damaged shear pins (48/2) (48/
