Hydraulic And Pneumatic Systems - PRONAR T386 Operator's Manual

Pronar T386
• Selection of trailer's working mode is only possible when the tipping frame is in its
rest position, hydraulic interlock is folded and the rear fender is maximally folded.
• Proper setting of the trailer to "hook trailer" function or "tipper" function must be
signalled by a corresponding indicator light – see chapter 4.5 "TRAILER
OPERATION".
• While connecting load box arrange it in such a way that the longitudinal axis of
the trailer is aligned with the longitudinal axis of the load box. If not, the load box
longitudinal members of the frame may not fit on the trailer rollers lengthwise.
While pulling in the load box is necessary to observe whether its longitudinal
members are properly supported on the trailer guide rollers. If necessary
manoeuvre the trailer, to connect the load box properly.
• Lock the load box on the trailer using the hydraulic lock of the load box.
Corresponding indicator light must light up when the load box is completely
locked – see chapter 4.5 "TRAILER OPERATION".
• Other persons must NOT be in the immediate vicinity of the trailer and especially
behind the connected or disconnected load box.
• Take particular care while working near electric power lines.

2.1.4 HYDRAULIC AND PNEUMATIC SYSTEMS

• When operating, the hydraulic and pneumatic systems are under high pressure.
• Regularly check the technical condition of the connections and the hydraulic and
pneumatic conduits. There must no oil or air leaks.
• Periodically drain water from the air tank in pneumatic system. During frosts,
freezing water may cause damage to pneumatic system components.
• In the event of malfunction of the hydraulic or pneumatic system, do not use the
trailer until the malfunction is corrected.
• When connecting the hydraulic conduits to the tractor, make sure that the
hydraulic system of the tractor and the hydraulic system of the trailer are not
under pressure. If necessary reduce residual pressure in the system.
