C. STARTER ROPE REPAIR AND REPLACEMENT
• A starter rope that breaks next to the pulley
can be repaired.
• Replace a starter rope that breaks more than
2 or 3 Inches from the pulley.
WARNING!
Always wear eye protection when ser­
vicing the starter rope. The recoil
spring beneath the pulley is under ten­
sion. If the spring should pop out seri­
ous personal injury could result.
NOTE: The recoil spring, located beneath the
pulley, is under tension.
If spring pops out, it
will require considerable time and effort to
reinstall. For this reason, you may want to let
your Sears Service Center handle this repair.
If you do try to repair the starter rope and the
recoil spring pops out, take the unit to your
Sears Service Center.
1. Remove the four screws on the side of the
fan housing. Figure48.
NOTE: Notice the different lengths of the
screws and their proper locations while
removing the screws.
2. Remove the fan housing.
3. If the starter rope is not broken, release the
spring tension by pulling about12 inches of
rope from the pulley and catch the rope in
the notch as shown. Figure 49 .
NOTE: The tension on the starter spring will
be released if the rope has broken.
4. Turn the pulley counterclockwise until the
spring tension is released.
