How to check the hydraulic
system
To set or check the hydraulic oil flow and the
pressure relief valve we recommend using the
Chicago Pneumatic test equipment or similar test
equipment.
0-250 bar (0-3600 psi)
5-46 l.p.m. (1-12 US gal/min)
Part Number 3371 8011 54
1.
Stop the engine (see "Stopping the engine").
2.
Connect the test equipment to the power
pack. Male (B) to the return connector and
female (A) to the feed connector on the
power pack. Make sure that the loading
valve of the test equipment is fully open.
3.
Start the engine (see "Starting the engine").
4.
Move the by-pass valve on the power pack to
the ON position.
5.
Turn the loading valve, until the gauge
shows approx. 70 bar (1000 psi) and allow
the power pack to warm up for 3-4 minutes.
6.
Slowly close the loading valve, until the
pressure gauge shows a pressure of 100 bar
(1400 psi).
7.
Check that the flow is according to the flow
rate in the technical specifications.
Note! The inaccuracy of the reading on the flow
meter is ±2 l.p.m. (±0.5 US gal/min). If the
performance is not in accordance with the
technical specifications for the power
pack, please see "Troubleshooting".

Safety and operating instructions

Maintenance

general
Regular maintenance is a fundamental prerequisite
for the machine to continue to be safe and
efficient.
Do not use a machine that is due for regular
service. Rectify any defects found during regular
maintenance before clearing the machine for use.
Note! Maintenance must only be done by
suitably qualified and competent persons.
Before doing any maintenance, make sure
that the machine is safe and correctly sited
on the ground.
Daily
Clean and inspect the machine.
Check fuel lines, tank, fuel cap and fittings for
cracks or leaks. Replace if necessary.
Check for damage.
Check hydraulic oil level.
Check engine oil level.
Check hydraulic couplings.
Check hydraulic hoses.
Check hydraulic oil filter.
Note! When the filter gauge needle remains in
the red sector (while the engine is running
idle and the oil is service warm), the filter
must be replaced. The old filter is removed
by turning it clockwise (use a filter strap
wrench if necessary). Tilting the power
pack rearwards will minimise oil spilling.
Before mounting the new filter, it is
recommended to grease the surface of
the seal with oil in order to ease correct
tightening of the filter.
Note! Check tightness of nuts, bolts, screws and
hose fittings after the first days of
operation and thereafter in accordance
with the maintenance schedule.
Note! The engine oil should be replaced after the
first 8 hours of operation and thereafter in
accordance with the maintenance
schedule in the engine manufacturer's
operating and maintenance instructions.
