6.2 MAINTENANCE
By following a careful service and maintenance pro-
gram for your machine, you will enjoy many years
of trouble-free service.
A set of V belts transmits rotational power to the
blower. They must be kept properly tensioned
and the pulleys aligned to obtain the expected
performance and life.
To check the tension and alignment, follow this
procedure:
1. Clear the area of bystanders, especially
small children.
2. Place all controls in neutral, stop engine,
set park brake, remove ignition key and
wait for all moving parts to stop before
dismounting.
3. Measure the length of the compression
spring. It should be adjusted at 6 3/4
inches (171 mm).
4. Open guard over belt, release tensioner
and replace belt when required.
