WARNING

Risk of ejected parts - Make sure that all blades are connected securely.

Check that

all blades are connected securely and that none of the blades is missing. Loose,
damaged, or missing blades can cause ejection of parts from the mower. Only use
locking nuts for fastening the blades.

7.3.1

Fastening of the blades

The blades are connected with a a central bolt and two shear bolts. To protect the blades and the bearings of

the mower, the shear bolts break or bend if the blades hit a rock, or other heavy obstacle.
The shear bolts and the timing of the blades must be checked after the blades collide heavily with an obstacle.

The shear bolts must be replaced with new ones when they show signs of deformation.

1.

Two shear bolts, regular grade 8.8

M6x25 screws, secured with nyloc

locking nuts.

2.

Centre bolt with locking washer. When

fitting the blades back to the mower, a

lock washer must be fitted under each

bolt.

The fastening bolts and nuts must be replaced with new ones when replacing blades.

7.4

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 fan rotor that is dirty loses its balance. The rotor that is out of balance may
damage the fan's hydraulic motor, so clean the rotor carefully and regularly.



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, leaking tubes will significantly

decrease the collector performance.



If the rotor remains out of balance after cleaning, it might be damaged. A damaged rotor must be

repaired or replaced to prevent damage to the hydraulic motor. In this case, contact AVANT service.

DANGER

Risk of high pressure fluid injection through skin - Release residual pressure
before maintenance.

Never handle hydraulic components when the hydraulic system is

pressurised. High pressure hydraulic fluid may cause serious injuries. Disconnect
hydraulic hoses before removing collector tubes or reaching to the collector fan.
