11.4 V-belt maintenance

Maintenance interval:
Every 10 operating hours
Check the V-belt for wear and damage by
means of a visual inspection and replace if
necessary.
Check V-belt tension and adjust as
required.
Insufficient tensioning increases V-
belt wear, excessive tensioning
may lead to bearing damage.
If you do not have the necessary
knowledge to adjust the V-belt, you
should have a technician perform
this work.
Checking V-belt tension:
● Detach the spark plug socket.
● Loosen screws (1), but do not unscrew
fully (remain on belt guard) and remove
belt guard (2).
● Using your thumb, press on the V-belt
between the two V-belt pulleys.
It must be possible to depress the V-
belt by approx. 10 mm.
Adjusting V-belt tension:
● Loosen the engine mounting (not
illustrated):
Loosen 3 bolts of engine mounting, but
do not remove; counterhold nuts on
upper side.
● Tension the V-belt by turning the
adjustment nut (3).
● After adjustment, re-tighten the engine
fastening bolts and install the belt
guard.
