FLEXIBLE DRIVE SHAFT MAINTENANCE
The flexible drive shaft has been lubricated at the
factory. After approximately every 40 hours of opera-

loosen the lower handle and slide
it
toward the
engine assembly to expose the clamp. Loosen the
clamp and separate the upper and lower tube as-
semblies. The shaft will then be able to be pulled
from the lower tube (Fig. 9).
