SECTION 4 Pronar T386
4.11
When the hydraulic support is lowered, set the manifold lever in tractor
to "neutral" position and set the support valve (4) to "Z" position -
closed – figure (4.2).
Set the hydraulic section in the tractor, to which the support is connected, to
"floating" position in order to reduce pressure in hydraulic conduits.
High pressure will occur at the connector after closing the support
valve and it will be impossible to reconnect the conduit after taking it
out.
WARNING
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.
Disconnect the connection lead of the control panel and dismount the panel
from the operator cab.
Turn off tractor engine. Ensure that unauthorised persons do not have access
to the tractor cab.
Disconnect from the tractor the conduits of the turning interlock hydraulic
system and the conduits of the hydraulic system of drawbar and hydraulic
support (option).
Disconnect pneumatic system conduits and electrical leads from the tractor.
Protect conduit ends with caps and place them on the hanger.
Release tractor hitch and disconnect trailer drawbar from tractor hitch and
drive tractor away.
WARNING
Do NOT park the loaded trailer, which is disconnected from the tractor and resting on the
parking support.
Before moving off, make sure that the support is maximally raised and secured against
dropping.
