The parking brake lever has two function modes, which
are determined by the small pawl control clip (A).
To change between the
two modes, turn the clip.
Pos. 1: The pawl control
clip must point
away from the
pawl.
Pos. 2: The pawl control
clip must rest
against the pawl.
To disengage the parking brake:
1. Set pawl control clip in pos. 1.
2. Pull the lever a little forward to release the pawl from
the ratchet and then push the lever fully backwards.
To engage the parking brake:
1. Set pawl control clip in pos. 2.
2. Pull the lever firmly forwards until parking brake is
fully engaged.
Emergency brake
1. Set pawl clip in pos. 2.
2. Attach the rope from the hole in top of the handbrake
lever (B) to e.g. the tractor top link attaching point. If
the sprayer is accidentally unhooked during transport
the rope will apply the parking brake before the rope
breaks.
IMPORTANT! To ensure safe engagement and to avoid
damages to the parking brake use rope with an ultimate
stress between 690 N (155 lb.) and 785 N (176 lb.).

This requires a special trailer brake valve attached to the
tractor hydraulic and brake system. Connect the snap
coupler to the tractor brake outlet. When the tractor
brakes are applied, the trailer brakes will work propor-
tionally to the tractor brakes, and ensure safe and
effective braking.

braking will therefore be hazardous.
IMPORTANT! Max. oil pressure is 150 bar (2175 p.s.i.)
in the brake line.
Relieve parking brake before driving.

This system requires a tractor with
compressor and air brake system with
out-let(s) for trailer brakes.
IMPORTANT! The load apportioning
valve must be set at the position
corresponding to the load on the
trailer, for obtaining optimal air pres-
sure to the trailer brakes.
= Relieved
= Empty tank
WARNING! Driving with wrong load apportioning
valve setting, will make the brakes under- or over-
apply, which can cause hazardous situations.
NOTE! 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 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 engaged as
long as there is air in the tank! Cover the couplings with
the dust flaps when hoses are disconnected.
