ATTENTION! The load apportioning valve must be set at the
position corresponding to the load on the trailer, for obtai-
ning optimal air pressure to the trailer brakes.
WARNING! Driving with wrong load apportioning valve set-
ting, will make the brakes under- or overapply, which can
cause hazardous situations.
Flip the snap coupler protection flap away and connect the brake system snap coupler to the tractor outlet (black) and
let the compressor fill the sprayer’s air reservoir.
Check brake circuit for leaks.
Flip the snap coupler protection flaps away and connect the two snap couplers for supply and control to the tractor out-
lets, and check brake circuits for leaks.
The couplers are colour coded and secured against incorrect attachment:
Red = Supply line (RH)
Yellow = Control line (LH)
Relieve parking brake before driving.
This system requires a tractor with compressor and air brake system
with out-let(s) for trailer brakes.
If the air hose(s) are disconnected with air in the brake air tank, con-
trol pressure will be dumped and the brakes will engage fully. If the
sprayer must be moved with air in the tank and without the air
hose(s) connected to the tractor, the load apportioning valve must
be set at “relieved” to disengage the brakes. Remember to reset the
handle to brake position again afterwards. When parking the sprayer,
always engage the parking brake, as the air brakes will only be enga-
ged as long as there is air in the tank! Cover the couplings with the
dust flaps when hoses are disconnected.
Positions for load apportioning valve:
1. Relieved
2. Full tank
3. Half full tank*
4. Empty tank
*If axle load exceeds 5250 kg. position 2 is required to be used.
Dual-line brakes (optional equipment)
Single-line brakes (optional equipment)
Air activated brakes (optional equipment)
