4 - Sprayer setup
52
Air activated brakes (optional)
This system requires a tractor with compressor and air brake system with
outlet(s) for trailer brakes.
If the air hose(s) are disconnected with air in the brake air tank, control
pressure will be dumped and the brakes will engage fully.
If the sprayer e.g. must be moved, the load apportioning valve must be
set. Remember to reset the handle to brake position again afterwards.
*If axle load exceeds 5250 kg. position 2 is required to be used.
μ
ATTENTION! When parking the sprayer, always engage the parking brake, as the air brakes will only be engaged as
long as there is air in the tank! Cover the couplings with the dust flaps when hoses are disconnected.
μ
ATTENTION! The load apportioning valve must be set at the position corresponding to the load on the trailer, for
obtaining optimal air pressure to the trailer brakes.
±
WARNING! Driving with wrong load apportioning valve setting, will make the brakes under- or overapply, which can
cause hazardous situations.
