ELIMINATION OF LEAKS
If leaks appear at conduit connections
then tighten the connections using the
specified torque and recheck the connec-
tions. If the problem still exists, replace the
leaky component.
If oil is found on hydraulic cylinder body,
check origin of leak. Inspect seals when
hydraulic cylinder is completely ex-
tended. 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. Do NOT use the trailer if
any of the hydraulic systems is damaged,
until the fault is removed.
