Tractor hydraulic system requirements
When connecting, no persons may stay in the space between the tractor and the machine.

The machine aggregated with the tractor changes the distribution of the weight to the individual axles of the
tractor. The weight of the front axle is reduced and therefore the controllability gets worse. It also affects
braking properties.

For safety reasons, the loading capacity of the axles, the tires and the tractor suspension must be kept. The
category of the tool suspension and three-point suspension of the tractor must be the same. Use only the
weights prescribed by the tractor manufacturer for balancing.
3.2.

HYDRAULICS CONNECTION

 Connect the hydraulics only when the hydraulic circuits of the machine and the
tractor (aggregate) are in a pressure-less condition.
 The hydraulic system is under high pressure. Regularly check for leaks and
immediately remove obvious damage of all lines, hoses, and pipe unions.

When seeking and removing leaks, use only the suitable tools.

For connecting the hydraulic system of the machine to the tractor, use the plug (on
the machine) and the socket (on the tractor) of the quick-couplers of the same type.
Perform the connection of the quick-couplers of the machine (fig.4) to the hydraulic
circuits of the tractor so that the folding of the side frames (BLUE DUST CAP - the
slide-out function of the linear hydraulic motor and WHITE DUST CAP - the
slide-in function of the linear hydraulic motor) is on one control circuit.
In order to prevent accidental or foreign person (children, passengers) caused movement of the
hydraulics, the control switchboards on the tractor must be secured or blocked in the transport
position.
It is forbidden to disassemble the parts of the hydraulic system that are under pressure.
Hydraulic oil that penetrates skin under high pressure causes serious injuries. In case of an injury
immediately seek medical help.
3.3.

FOLDING AND UNFOLDING OF THE MACHINE

 With all hydraulic movements, lower the speed of the moving parts of the machine before stopping by
throttling the corresponding valve at the control unit!

The hydraulics for the folding and unfolding must be connected to the double-action control unit.

The operator must ensure that during folding and unfolding of the side frames, no person or animal is within
their reach (i.e. at the place of their impact) or vicinity and that no one puts his fingers into the joint space.

Perform folding and unfolding on flat and solid surfaces or laterally to the slope with the fully open control
unit.
