Quick-coupler (0) is directly connected with the area of
final house driving and is designed for returned oil from
external hydraulic devices (e.g. from rotation hydro
engines etc.).
Quick-couplers engagement and disengagement
With quick-couplers engagement and
disengagement take greater care with regard for
residualoil, remaining in socket or on a plug of
a quick-coupler.This residual oil must be removed
from ecological reasons after each quick-couplers
disconnection with any textile material.
Connecting machines and tools to External hydraulic circuit
Connecting double-acting roller
Connect double-acting roller always to quick-couplers of one section.
Connecting machines and tools assembled from more parts
When working with agricultural machines which are assembled from more parts (combiners, shears,
harrows), in which side frames are jointly connected to a central frame, tilted to vertical position by separate
hydraulic rollers in transport, controlled by tractor external hydraulic circuit, it is advisable to connect lifting
branches of rollers to quick-couplers (2) or (4), which are equipped with a reverse valve.
Connecting rotation hydro engine
If there is a rotation hydro engine connected to external hydraulic outlet, it is necessary to connect its reverse
branch, always to a quick-coupler (0).
Connecting reversing rotation hydro engine
Reversing rotation hydro engine must be for function connected to quick-couplers of one section. When
connecting hydro engines, securing valves need to be included in both branches, which reliably restrict
pressure peaks with machine run-out. Waste from these valves is connected to a quick-coupler (0).
Auxiliary machines using oil filling of external hydraulic circuit must be filled with the same
kind of oil, which is recommended for gear system of the tractor! Quick-couplers sockets of an
auxiliary machine need to be properly cleaned before connecting.
