Hydraulic System
As with all hydraulic systems, it may be necessary to
periodically check and adjust the pressure relief
settings. It may be that a major hydraulic component
has been changed, that the vehicle is not performing in
terms of payload, or that the vehicle has recently been
put into service and the system requires adjustment
following a run-in period.
General Maintenance
To keep the hydraulic system efficient and reliable, the
following care must be taken:
Every day, check that hydraulic lines and
connections are not leaking. Correct if necessary.
Inspect the pump for leaks or unusual noises.
When maintenance is carried out, protect all hoses,
fittings, pipes, or any other ingress points from dirt
that would eventually get into the oil. Plug hoses
that are not connected.
Inspect the hydraulic system at least once a month,
and adjust pressure if necessary (see
Danger!
Always lock out and tag out the vehicle
when inspecting or performing
maintenance on the vehicle (see
Out and Tagging Out the Vehicle
Danger!
Human skin can be easily penetrated by
high pressure oil (2000 PSI and above).
Failure to take appropriate safety
precautions may result in serious injury or
death.
Danger!
Because of extreme overhead dangers,
equipment must be properly supported
when servicing sections on the hydraulic
system.
