IMPORTANT!
Trailer may only be hitched to a tractor, which has the appropriate hitch, connection
sockets for braking, hydraulic and electrical systems, and hydraulic oil in both machines
is the same type and may be mixed.
Do NOT travel with trailer which has an unreliable brake, lighting or signalling system.
When hitching is completed, secure the electrical leads and hydraulic and braking system
lines in such a way that they do not become entangled in tractor's moving parts and are
not at the risk of breaking or severed when making turns.
Disconnecting the trailer
IMPORTANT!
The trailer may not be unhitched from the tractor, if the tipping frame or central frame are
not fully retracted and when hydraulic cylinder suspension blocks are extended.
In order to disconnect the trailer from the tractor carry out the following actions in the
following sequence.
Immobilise tractor and trailer with parking brake and place chocks under trailer
wheels.
Wheel chocks shall be so placed that one of them is in front of the
wheel and the second is behind it.
Set valve (3) of hydraulic support to open position (O) – figure (4.1).
Lower the support to enable safe unhitching of the trailer.
Operate the selective control valve on the tractor in the direction
corresponding to the hydraulic support cylinder piston extension.
When the hydraulic support is lowered, set selective control valve
lever to "neutral" position.
Close the hydraulic support valve to lock the support in a fixed
position.
If the trailer is equipped with a mechanical support, secure it with
locking pin provided after adjusting the drawbar eye to correct height.
