Troubleshooting
Problem Posible cause(s) Solution(s)
The hydraulic oil is
over heating
(temperature
higher than 180°F
or 77°C)
The oil level in the
hydraulic tank is too low.
Add oil to the tank upto the
required level. Refer to
“Hydraulic Oil” on
page 123.
Hydraulic pressure is either
too low or too high.
Perform the hydraulic
pressure adjustment
procedure.
The oil doesn’t have the
proper grading (i.e. too thin
in hot temperatures and
too thick in cold
temperatures).
See “Recommended
lubricants” on page 123 to
find out about the proper
type of oil to use. Refer
also to “Hydraulic Oil
Replacement Procedure”
on page 92.
Contaminated oil Change the return filter.
Restrictions in the
hydraulic system
Check all hydraulic
components that may have
the presence of debris
causing restrictions in the
system. Have the pump
inspected by a specialist.
