DRIVE BELT TENSION AND ALIGNMENT
A set of V belts transmits rotational
power to the blower and pick-up head.
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.
4. Remove guard over belts.
5. The blower drive belt tension is set
by a spring loaded idler:
a. The belt should be set so that
it does not slip when operat-
ing.
b. The tension spring should
have at least 3 mm (1/8 inch)
space between the coils to
provide the required tension
when engaged.
c. Move the spring anchor bolt to
a new position to provide the
required coil spacing if the coil
spacing is less than 3 mm (1/8
inch) when engaged.
WARNING
Machine is shown with guard
removed for illustrative purposes
only. Do not operate machine
with guard removed.
