Brakes
Emergency and Parking Brake (optional)
The parking brake lever has two function modes, which are determined
by the small pawl (A). To change between the two modes, turn the pawl.
Disengage the parking brake
1.
Set pawl in position 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 position 2.
2.
Pull the lever firmly forwards until parking brake is fully engaged.
Emergency brake
1.
Set pawl in position 2.
2.
Attach the rope from the hole in top of the hand brake 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 a rope with an ultimate
stress between 690 and 785 N.
±
WARNING! Release the parking brake before driving!
Hydraulically 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! Maximum oil pressure is 150 bar in the brake line.
