HYDRAULIC SYSTEM MAINTENANCE

5.3.1 PRELIMINARY INFORMATION

Work connected with the repair, change or regeneration of hydraulic system components

(cylinders, valves etc.) should be entrusted to specialist establishments, having the

appropriate technology and qualifications for this type of work.

The duties of the operator connected with the hydraulic system maintenance include:

•

checking tightness and visual inspection of the system,

•

checking technical condition of hydraulic connections.

DANGER

Do NOT use out of order hydraulic system.

Do NOT use the trailer with out of order hydraulic brake system.

5.3.2 CHECKING HYDRAULIC SYSTEM TIGHTNESS

Scope of maintenance activities

Hitch trailer to tractor.

Connect all hydraulic system conduits according to maintenance instructions.

Clean connectors and cylinders.

Press tractor brake pedal several times.

Check hydraulic cylinders and conduits for tightness.

If oil leak is detected on hydraulic cylinder body, ascertain origin of leak. Inspect seals when

hydraulic cylinder is completely extended. Minimum leaks are permissible with symptoms of

"sweating", however in the event of noticing leaks in the form of "droplets" stop using the

trailer until faults are remedied. If unreliability is evident in brake cylinders, do NOT use trailer

with damaged system until faults are remedied.
