Hydraulic Settings
Once correctly set, the powerpack will maintain its performance for a long time. The oil
flow and the pressure relief valve should, however, be checked once a year.
To set the oil flow and the pressure we recommend using LIFTON test equipment or
similar test equipment.
LIFTON Test Equipment Test Set-Up
(1) Connect the test equipment to the quick-release couplings ”OUT” and ”IN” on the
powerpack, ensuring that the loading valve of the test equipment is fully open.
(2) Carry out the starting procedure.
(3) Move the by-pass valve on the powerpack to ”ON”.
(4) Turn the loading valve, until the gauge shows approx. 70 bar and allow the unit to
warm up for 3-4 minutes.
(5) Slowly close the loading valve.
(6) Adjustment of the pressure relief valve (mounted to the right on the valve block be-
hind the hose connections) is carried out as follows:
(a) Use two spanners: 9/16” (15 mm) for the lock nut and 1/2” (13 mm) to adjust
the setting (”IN” to increase pressure – ”OUT” to decrease pressure).
(b) Retighten the lock nut.
