BlockedNozzleOrNozzleDuct
If it is apparent that the suction nozzle is not picking up debris it may be that it is blocked or
that the body is full.
1. With the machine stationary and the suction still operative on the nozzle, open the Maxigap/
Varagap nozzle to increase the airflow and see if the obstruction clears.
2. If not, raise and lower the nozzle and see if the blockage clears.
3. If still blocked, switch off the engine(s), open the body access door and check that the mesh
screens are clear and that the body is not full.
4. If the screens are blocked, clean them and providing the body is not full return the machine
to service and check the nozzle performance.
5. If the body is over half full the machine should be emptied at the nearest waste site.
6. If the screens are clear, the body less than half and debris is still not being picked up,it may
be that the nozzle trunking or inlet tube is blocked.
7. With the vehicle on level ground carefully raise the body and rest it on the lowest body prop
position, raising the body any higher may affect the vehicle’s stability due to the load moving
within the body. Switch off the engine(s).
8. Clear any obstruction in the nozzle or inlet duct.
