8.1.4 First filling with hydraulic oil
When filling the hydraulic system, identify already
filled cylinders (with the sticker "first filling" on the sys-
tem) and unfilled cylinders (no sticker on the system).
Lifts with this sticker already have hydraulic oil in the
hydraulic cylinders.
First filling with sticker
Required oil volume: 9 litres (HLP 32) for system.
Lifts with this sticker already have hydraulic oil in the
hydraulic cylinders and hoses.
After setting up the electrical connection to the lift,
the hydraulic system can be filled.

• Loosen and remove the plastic part of the oper-
ating lever (9) of both Allen screws (10).
• Loosen and remove the unit cover.
• Unscrew the oil filling opening (11).
• Fill 9 litre hydraulic oil (HLP 32).
• Raise the lift approx. 1 m by pushing the operat-
ing lever (9). The lift rails can be lifted at different
times!
• Hang in the lifting arms and secure them.

• Push the operating lever forwards and raise the lift
to its uppermost end position.
• Push and hold the operating lever for another
60 seconds so air can escape from the system
and the overflow procedure equalises the lift to
each other.
For first commissioning, it is normal to have a dif-
!
ferent start up and a large "shaking" in the up-
permost position. Air trapped in the system must
be completely removed first.
• Afterwards lower the lift to its lowest position. Pull
the operating lever (9) and hold it until the lifting
arm is completely lowered.
The oil level should be approx. 30 – 40 mm be-
!
low the oil fill opening. Do not fill the oil tank up
to the upper edge, as otherwise during lowering
the oil return line can pull oil out of the line and
afterwards result in a very slow lifting at the up-
per range.
• After commissioning, the sticker (first filling) can be
removed.
First filling without sticker.
Required oil volume: 13 litres (HLP 32) for system,
hoses and cylinders.

lift, the hydraulic system can be filled.
• Loosen and remove the plastic part of the oper-

• Loosen and remove the unit cover.
• Unscrew the oil filling opening (11).
• Fill hydraulic oil: 9 litre (HLP 32).
• Raise the lift approx. 1 m by pushing the operating
lever (9). The lift rails can be lifted at different times!
• Hang in the lifting arms and provide with safety
rings.

• Push the operating lever (9) forwards and raise
the lift to its uppermost end position.
• Now fill the oil tank with hydraulic oil:
4 litre (HLP 32)!
• Afterwards hold the operating lever another 60
seconds so air can escape from the system and
the lift rails can be equalised by the overflow pro-
cedure.
