9.1 Ordinary maintenance

Check oil tank level; refill
if needed.
Check the circuit for
oil leakage.
Check seals for proper conditions and replace them,
if necessary.
Check bolts for proper tightening
and tighten with a torque wrench (See
table of values)
Verify that no noise changes
take place in the pump of the hydraulic control unit
when running and check fixing bolts
for proper tightening.
Check safety devices
for proper operation.

or ageing. Contaminated oil is the
main reason for failure
of valves and shorter life of
gear pumps.
Check all framework components
and check mechanisms to verify the absence of
any faults and malfunctions.
A check of the electrical system
to verify that control unit motor,
limit switches and control panel operate properly
must be carried out by skilled electricians.
