Periodic inspections of the trailer

PRONAR T672ECO
5.16 HYDRAULIC SYSTEM INSPECTION
• Hitch trailer to tractor.
Each time before connecting
the trailer to the tractor or con-
necting a second trailer, check
the hydraulic plugs and sockets.
• Secure the tractor and trailer with the
parking brake.
• Clean hose connections, hydraulic
cylinders and couplings.
• Start the individual hydraulic systems
several times by extending and re-
tracting the piston rods of the cyl-
inders. Repeat operations 3-4 times.
In case of a hydraulic tipping
system, perform several tipping
trailers tipping backwards or to
the side.
• If the trailer is equipped with hydraulic
braking system, press tractor brake
pedal several times.
• Check all hydraulic circuits for leaks.
If necessary tighten the con-
nectors if moisture is visible.
• After completing the inspection, put
all cylinders to the rest position.
If visible moisture appears on the cable
connectors, tighten the connector with
a specified torque and carry out the test
again. If the problem persists replace the
leaking element.
In the event of oiling on the hydraulic cyl-
inder body, the nature of the leakage must
be checked. When the cylinder is fully ex-
tended, check the seal locations. Small
leaks are permissible with symptoms of
"sweating", however
in the event of noticing leaks in the form
of "droplets", stop using the trailer until
the fault is remedied. If a malfunction has
appeared in the brake cylinders, it is for-
bidden to drive the trailer with a damaged
system until the fault is removed.
I.3.3.259.16.1.EN
DANGER
It is forbidden to use the trailer with inefficient hy-
draulic system.
It is forbidden to use the trailer with a defective hy-
draulic brake system.
