Key Maintenance Procedures
Cleaning the Suction Fan and Screen
Failure to comply with the following could result in serious injury.
Before working on the machine position it on firm, level ground and apply 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.
Never work under a raised hopper without the hopper safety prop being deployed.
Procedure to clean the fan and screen is as follows:
1. Turn engines off and remove ignition keys.
2. Use a suitable platform to reach the area above the rear door.
3. With the fan stationary, remove the outer and inner inspection
covers from the hopper to expose the fan.
4. 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 severely contaminated fans.
5. Refit the inspection covers.
6. Restart the auxiliary engine , see page 20, and using the remote open the rear door , see page 17.
7. Insert the rear door safety prop. See page 13. Turn off auxiliary engine and remove ignition keys.
8. Lower the suction fan filter screen, wash the screen using a steam cleaner or high pressure water from a remote source.
Raise and secure the screen.
9. Ensure that the rear door seal and its mating surfaces on the hopper are free from any foreign matter that might damage the seal or adversely affect the
sealing function.
10. Remove and stow the rear door safety prop.
11. Using the remote to close the rear door , see page 17.
Loose particles from the cleaning process can be ejected via the hopper cover when the fan is restarted, ensure that all personnel are clear before
restarting.
12. Restart the auxiliary engine , see page 20 and switch the suction fan on , see page 16.
13. If the sweeper has a rear inspection hatch and with the rear door shut and suction fan running, carefully open the inspection hatch, direct additional
water onto the suction fan screen just below the inlet cone until clean water is being expelled from the fan case/hopper cover.
