Control Of Technical Condition Of Hydraulic Connectors And Sockets - PRONAR T400 Operator's Manual

CHAPTER 5
Clean connectors and cylinders.
Open and close the tailgate several times.
Start the floor conveyor mechanism - check the smoothness of the chain
movement.
Perform a reversing maneuver and observe the hydraulic steering lock system
operation.
Open and close the front tilting extension several times.
Check hydraulic cylinders and hydraulic lines for leaks.
In the event of oiling on hydraulic cylinder bodies, the nature of the leakage must be checked.
When the actuator is fully extended, 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 removed. If a malfunction has appeared in the brake
cylinders, it is forbidden to drive the trailer with the damaged installation until the defect is
removed.
Checking for leaks:
5.4.3 CONTROL OF TECHNICAL CONDITION OF HYDRAULIC CONNECTORS
AND SOCKETS
The hydraulic connectors and sockets of the trailer and tractor must be technically sound and
kept clean. Tractor and trailer hydraulic systems are sensitive to the presence of solid
impurities, which may cause damage to precise components of the installation (impurities
may cause jamming of hydraulic valves, scratches on cylinder surfaces, etc.)
When the cylinder piston rod is fully extended, check the cylinder bore
for signs of seizing and deep scratches.
Help from another person is required.
When the cylinder piston rod is fully extended, check the cylinder bore
for signs of seizing and deep scratches.
• after the first week of use,
