MAINTENANCE

By following a careful service and maintenance program for your machine, you will enjoy many years of
trouble-free service.
5.2.1

BELT TENSION AND ALIGNMENT

Rotational power from the electric motor is trans-
mitted to the blower through the belt drive. To
obtain efficient transmission of power and good
belt life, the belts must be properly tensioned and
the pulleys aligned.
Belts that are too tight will stretch and wear quickly
or overload the bearings on the motor or blower.
Belts that are too loose will not transmit the
required power and will slip, overheat and wear
quickly. Pulleys that are not aligned will result in
rapid belt wear.
Follow this procedure when checking and adjust-
ing belt tension and pulley alignment.
1. Clear the area of bystanders, especially small
children.
2. Turn machine off, lock out tag out master
control panel and wait for all moving parts to
stop before starting maintenance work.
3. Unlatch and remove the belt cover. Lay to the
side.
