5.4.2 CHECKING HYDRAULIC SYSTEM TIGHTNESS
Required maintenance actions
Hitch trailer to tractor.
Connect all hydraulic system conduits according to maintenance instructions.
Clean connections and cylinders (tipping cylinder and possibly hydraulic brake
cylinders).
Conduct test tipping of load box sideways and backwards.
Press tractor brake pedal several times.
If trailer is equipped with hydraulic brake system.
Check hydraulic cylinders and conduits for tightness.
If leaks appear at connections then tighten the connections.
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.
Checking tightness:
•
after the first week of use,
•
every 12 months of use.
