Operating Instructions
Basic maintenance
Cleaning the suction fan
Failure to comply with the following could result in serious injury.
Before working on the machine position it on firm, level ground and apply the handbrake.
The fan is an extremely heavy rotating mass. Never attempt to slow or stop its rotation by using the hands or by inserting any item into the fan
chamber, even at low speeds.
Follow the procedure below:-
1. Unlock rear door. Raise the hopper fully , and deploy the
hopper safety prop. Turn engine off. Remove ignition keys.
The hopper safety prop must always be deployed when the
hopper is in the raised position. Failure to do so could result in
serious injury.
2. With the fan stationary, remove the outer and inner inspection
covers from the hopper to expose the fan.
3. Using the special scraper, thoroughly clean all parts of the fan. A
steam cleaner or high pressure water from a remote source will
greatly assist in cleaning contaminated fans.
4. Refit the inspection covers, unlatch and stow hopper safety prop.
5. Start engine and lower hopper . Turn off engine.
6. Proceed to page 48 to clean hopper filter screen.
Please pay particular attention to the
inner curve of each impeller blade, as
indicated by the green/yellow arrow,
and around the centre of the unit as dirt
accumulates around the hub area.
