Checking the hydraulic
system
To set or check the hydraulic oil flow and the
pressure relief valve we recommend using Chicago
Pneumatic or similar test equipment.
♦
0-250 bar (0-3,600 psi)
♦
5-46 l.p.m. (1-12 US gal/min)
1. Stop 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.
3. Make sure that the test equipment loading valve
is fully open.
4. Start the engine/motor.
5. Move the by-pass valve on the power pack to
the on position.
6. Turn the loading valve, until the gauge shows
approximately 70 bar (1,000 psi) and allow the
power pack to warm up for 3-4 minutes.
7. Slowly close the loading valve, until the pressure
gauge shows a pressure of 100 bar (1,400 psi).
8. Check that the flow is according to the flow rate
in the technical specifications.
9. The accuracy 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, see section
"Troubleshooting".
Transport
During transport make sure the power pack is
secured. Ensure that the power pack is upright
during transportation and lifted with approved lifting
equipment.
Operation
WARNING
Involuntary start
Involuntary start of the machine may cause injury.
►
Keep your hands away from the start and stop
device until you are ready to start the machine.
►
Learn how the machine is switched off in the event
of an emergency.
►
Stop the machine immediately in all cases of
power supply interruption.
Operating
Preparation before starting
The following checks must be made each time you
start to use the power pack. All these checks concern
the serviceability of the power pack. Some concern
your safety:
♦
Clean all safety labels. Replace any that are
missing or cannot be read.
♦
Inspect the power pack and hoses generally for
signs of damage.
♦
Remove dirt and debris especially from the
linkages and hydraulic oil cooler.
♦
Check for oil and fuel leakages beneath the power
pack.
♦
Ensure that the hydraulic couplings are clean and
fully serviceable.
♦
Check all fastenings.
♦
Check the hydraulic oil level and add as necessary.
