6.8 Collector unit
Cleaning of the collector nozzle and the collector fan is important for their smooth
operation. If the nozzle is dirty, grass starts to stick to it and will eventually block the fan.
Also, a dirty fan rotor loses its balance. A rotor that is out of balance may damage the
fan's hydraulic motor, so clean the rotor carefully and regularly.
Disconnect hydraulic hoses before removing collector tubes or reaching to the collector
fan.

The collector nozzle is pivoted and held by a spring, the nozzle can be tilted up for quick cleaning.

To clean the fan rotor, first remove the collector tubes and then clean the rotor blades one by one,
turning the rotor manually.

Check the collector tubes and keep them clean as well. Damaged tubes will significantly decrease the
collector performance.

If the rotor remains out of balance after cleaning, it may be damaged. A damaged rotor must be
repaired or replaced to prevent damage to the hydraulic motor. In this case, contact AVANT service.
