Full lift
Lifting the axle to the maximum height. The stop
valve is not activated. Lever position –on the
left.
Used for transport and folding.
Accelerated short lift
The stop valve is activated. It restricts the height
of the lift of the axle as set. Lever position –on
the right.

Disc circuit closure
Used to restrict unintentional movement of discs when the machine is folded (a risk of collision)
The unintentional movement of discs may also be caused when the yellow axle circuit is used (linked
function). The valve closure prevents that.
Locked discs
The green circuit valve is closed. Discs cannot be
moved.
Discs must be maximally drawn in for folding.
The valve must be closed.
Used for transport and folding.
Unlocked discs
The green circuit valve is open. The working
depth can be adjusted.
Used for work.
Shut-off valve on the drawbar piston-rod
Used for closing the supply of pressure oil to the
drawbar piston-rod
Prevents the machine from dropping when the
hose breaks during transport
It does not need to be closed when the machine
is resting on the drawbar washers for transport

1.4. BRAKE DISTRIBUTION OF THE MACHINE
The standard version of the machine includes a single-circuit two-line braking system by KNORR BREMSE
Braking is provided by spring brake cylinders –the parking brake is implemented inside and it is automatic
(controlled by a button, see below).
To release the parking brake, a sufficient air pressure in the system is required. Always check that the parking
brake is released before driving.
If the machine is equipped with brakes, they must be connected to the tractor when driving.
Always release the brakes of the machine when lifting the machine on the axle.
ATTENTION !!! The parking brake is activated automatically when there is a leak of air from the system and
physical brake release is only possible mechanically, see below.

1.4.2. Hand brake control valve
The rear axle brakes are equipped with an automatic manual brake, the function of which is described below.
The parking brake is automatically activated when the red quick coupling device is disconnected from the tractor.
Description of the manual brake control when air ducting is disconnected
When the air hoses are disconnected, the parking brake is automatically activated
To release the brakes for manipulation, use the black knob
The control is only functional when there is enough air in the air brake reservoir
The system is automatically changed over to the travelling (drawn out) position when pressurized
Released black knob
The parking brake is applied
Pressed black knob
The parking brake is released
The brake is only released when there is enough air in the air brake reservoir

Description of the manual brake control when air ducting is connected
The knob has to be pressed when travelling (there is no automatic change over).
It does not need to be used when the machine is disconnected, the brake is automatically
activated when the red quick coupling device of the tractor is disconnected.
1.4.3. Emergency brake release in case of air leak
It is possible to release the brakes of the machine using special brake release bolts in case of a leak of air from
the brake system.
The bolts are included in the installation unit of the brake cylinder.
Emergency brake release procedure in case of air leak
Remove the bolts from the holders of the brake cylinder (Picture 1 and 2).
Release the cap on the back side of the brake cylinder (Picture 3).
Insert the bolt by its flat end (T-shape) into the opening in the cylinder and turn the bolt by 90° at the end of
the opening so that the screw is arrested and cannot be pulled out (Pic. 4).
Turn the nut (19 mm spanner) clockwise (Pic. 5). ATTENTION: Maximum torque is limited to 68Nm.
