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 the
nominal pressure according to the
technical specifications
7. Check that the flow is according to
the flow rate in the technical specifi-
cations

SHOOTING
+/ )
A poorly maintained Power Pack is a haz-
ard. Doing regular maintenance and lubri-
cation jobs as listed in these schedules will
help keep the Power Pack in a safe work-
ing condition.
Apart from the daily jobs, the schedules
are based on the operation hours of the
Power Pack. Keep a regular check of
hours in use. Do not use a Power Pack
that is due for regular service. Rectify any
defects found during regular maintenance
before clearing the Power Pack for use.
Daily
1. Clean the Power Pack in general
2. Check fuel lines, tank, fuel cap and

3. Check for damages
4. Check hydraulic fluid level
5. Check engine oil level
6. Check hydraulic couplings
7. Check hydraulic hoses
8. Check hydraulic oil filter
