Brakes
Emergency and parking brake (optional)
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.
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.
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 to e.g. the tractor top link attaching point (B). If the sprayer
is accidentally unhooked during transport the rope will apply the parking brake before the rope breaks.
μ
ATTENTION! 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.).
±
WARNING! Relieve the parking brake before driving!
Hydraulic activated brakes (optional)
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
proportionally to the tractor brakes, and ensure safe and effective
braking.
±
WARNING! Do not connect the brakes directly to the tractor
hydraulics without the brake valve. The trailer brake power
cannot be controlled, and braking will therefore be hazardous.
±
WARNING! Max. oil pressure is 150 bar (2175 p.s.i.) in the brake line.
