5.14   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 connectors and 
sockets.

•  Secure the tractor and trailer with the 

parking brake.

•  Clean hose connections, hydraulic 

cylinders and couplings.

•  Start all hydraulic systems several 

times by extending and retracting the 
piston rods of the cylinder.

•  Start all hydraulic systems several 

times by extending and retracting the 
piston rods of the cylinder.

•  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 connectors at the 

specified torque and retest. 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. Minor 
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.3.4.622.16.1.EN

 DANGER

It is forbidden to use the trailer with a defective pneu-

matic system.

It is forbidden to use the trailer with a defective park-

ing brake system.
