Connecting And Disconnecting Quick-Couplers; Quick-Couplings With Drip Collection; Hydraulic Distributor Of The Outer Hydraulic Circuit - Zetor CRYSTAL Series Operator's Manual

Connecting and disconnecting quick-couplers

When connecting and disconnecting the quick-couplers pay increased attention with regard to
the residual oil that remains in the socket or on the plug of the quick-coupler. For environmental
reasons after every disconnection of quick-couplers this residual oil must be removed with any
textile material.

Quick-couplings with drip collection

On request, dripping system for holding leakage oil can be
installed. Regularly check whether the tank is not full;
dispose of the oil in an environment-friendly way.

Hydraulic distributor of the outer hydraulic circuit

The outer circuit of the tractor hydraulics is controlled by
the distributor with three four-position sections controlled
by levers.
The control levers of the sections are located in the cabin
on the mudguard of the right rear wheel.
The numbers on the label of the control levers correspond
to the numbers of the quick couplers.
The levers controlling both end sections are locked in the
rear position at maximum oil flow rate into the quick
couplers 2 or 6. After overcoming the increased resistance
the locked lever can be returned into the position (N).
The quick couplers 2, 4 and 6 are equipped with the return
valve - use for the connection of the working branch of the
machine with the increased requirement for tightness -
minimum drop of the tools e.g. during transport.
