Replacing the return spring
Remove the fan housing (see above under “Replacing the
starter cable”).
Remove the air guide from the fan housing (see above under
“Replacing the starter cable”).
Take off circlip (1) (circlip pliers, see “Accessories”).
Remove the cable pulley (2).
Unscrew screw (3).
Evenly lever the return spring (4) out of the catch using a
screwdriver or similar tool. Be extremely careful - the return
spring is under tension and can pop out of its housing!
CAUTION! Injury hazard! Wear eye protection and work
gloves when performing this work!
Replacement return springs are delivered already tensioned in
the housing. CAREFUL - the spring can pop out. If it does, it
can be put back in as shown in the diagram (observe the
direction of rotation).
Grease the new return spring (4) with multi-purpose grease,
part no. 944 360 000, then insert it and tension it slightly so that
the lugs (5) click into their holes.
Screw in bolt (3) but do not tighten it hard.
Turn the cable pulley slightly when putting it back on, until you
hear it catch. Put the circlip back on.
Wind on the starter cable (see above under “Replacing the
starter cable”).
Reinstall the air guide (see Fig. A)
When replacing fan housing, it may be necessary to pull the
starter cable lightly so that the cable pulley catches.
Guide the cable into the recess (24) on the cable drum and use
the cable to turn the drum two turns in the direction shown by
the arrow.
Holding the cable drum in your left hand, straighten out the twist
in the cable with your right hand, pull the cable tight, and hold.
Release the cable drum. The drum´s spring force will now wind
the cable around the drum.
Repeat this procedure twice. The starter handle must stand out
from the fan housing.
NOTE: With the cable pulled all the way out, it must still be
possible to turn the pulley another 1/4 turn against the return
spring.
CAUTION! Injury hazard! When you pull out the starter
cable hold the starter handle firmly. It will whip back if the
cable pulley is released by accident.
Reinstall the air guide in the reverse order (fig. G on page 21).
Make sure that the guide (25) is lined up with the hole (26) in
the fan housing.
When replaceing fan housing, it may be necessary to pull the
starter cable lightly so that the cable pulley catches.
