5.2 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 engine is transmitted to the blower through the belt drive. To obtain
efficient transmission of power and good belt life, ensure the belts are properly tensioned and the
pulleys are aligned.
Belts that are too tight will stretch and wear quickly or overload the bearings on the input shaft or
the blower. Belts that are too loose will not transmit the required power and will slip, overheat and wear
out quickly. Pulleys that are not aligned will result in rapid belt wear.
Follow this procedure when checking and adjusting the belt tension and the pulley alignment.
1. Clear the area of bystanders, especially small children.
2. Place all controls in neutral, stop the engine/power source, remove ignition key and wait for all the
moving parts to stop before dismounting.
3. Unhook the PTO driveline from the tractor shaft or the power source. This will allow you to turn the
pulleys if required.
4. Remove the bolts securing the belt cover, and remove the belt cover. Lay the belt cover to the side.
