Occasional maintenance
General information
The maintenance and replacement intervals for the following will depend very much on the conditions under which the
sprayer is operated and are therefore impossible to specify.
Compressed air pressure adjustment
An air compressor is used for the operation of the suspension of the sprayer. The service pressure must be between 130 psi
(9 bar) and 145 psi (10 bar).
• Raise the engine hood to access the adjustment of the air
compressor, located on the left side of the engine.
• Unscrew the protective cover (1).
• Loosen the lock nut (2) and turn the adjustment screw (3) to adjust
the suspension service pressure.
Air suspension adjustment

Note: Adjustment of the suspension is performed with an empty
tank.
Check beforehand that the compressed air pressure is adjusted
correctly.
When service pressure is reached, the front upper arm and rear lower
arm should be level.
If the height of the air bag needs adjustment, you can modify it by
adjusting the linkage:
• Adjust linkage (1) to change the height of the front air bag.
• Adjust linkage (2) to change the height of the rear air bag.
