4 - Sprayer Setup
Air Activated Brakes (1
This system requires a tractor with air compressor and air brake system
with outlet(s) for trailer brakes.
If the air hose(s) are disconnected with air in the air brake tank, the
control pressure will be dumped and the brakes will engage fully.
If the sprayer must be moved, the load apportioning valve must be set.
Remember to reset the handle to brake position again afterwards.
Position State Use
1 Relieved Move sprayer with air in the tank and without the air hose(s)
connected to the tractor. Disengages the brakes.
2 Full Use when driving with full tank.
3 Half full* Use when driving with tank half full.
4 Empty Use when driving with empty tank.
*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 a wrong setting for the load apportioning valve will result in excessive or insufficient braking,
which can cause hazardous situations.

Manual Control of Air Brakes

The braking system can be controlled manually to move the trailer,
when it is not coupled to the tractor.
Near the platform at the front of the trailer, a black and a red operation
button are installed in the braking system. Symbols are placed between
the buttons to indicate their function (see picture to the right).
Black button (A)

• Push in to disengage the service brakes.
Red button (B)
