• Move the lifting upwards to approx. 1,500 mm.
• Check the alignment of the base plates again
and anchor the lift. Holes for floor anchoring are
to be placed through the holes in the base plates.
Clean the bore holes by blowing them out with
air. Insert safety anchors into the holes.
The manufacturer recommends using approved
safety anchors and to follow anchor manufactur-
er's instructions.
Before anchoring the lift, check whether the con-
crete is of quality C20/25 up to the finishing level
of the completed floor. In this case, take the an-
chor length from the anchor manufacturer's data
sheet. If there is a floor covering (tiles, screed) on
the weight bearing concrete, the thickness of this
covering must be determined.
• Anchor the unit to the floor.
• Align the lift.
To prevent hollow spaces, correct any uneven-
ness in the floor by putting shims under the base
frame (e.g. thin metal strips). Use suitable supports
to ensure continuous contact between the floor
and base frame.
• Tighten safety anchors with torques recommend-
ed by the manufacturer.
Each anchor must be tightened to the required
!
torque. Safe operation of the lift is not guaran-
teed with a lower torque. Follow the instructions
of the anchor manufacturer.
• Move the lift upwards and downwards several times,
then check the anchors with the torque wrench
and tighten if required. Check the hydraulic lines for
leak-tightness.
• Balance the lift again if required.
• Mount all hose covers.

Fill and vent the hydraulic systems

The lift is preinstalled at the factory, however the
hoses must be connected to the unit.
Check the power connection, check for correct
hydraulic oil in the proper volume and leak-tight-
ness of the connection when setting up the lift. Air
may be entrapped resulting in start up problems or
challenges with smooth running.
Check and ensure proper allocation of hose con-
nections.
After setting up the lift, the hydraulic system can be
filled.
Required oil volume: 14 litres HLP 32:

• Loosen and remove the plastic handle of the op-
erating lever of both Allen screws.
• Loosen and remove the unit cover.
• Unscrew the oil filling opening.

• Refill hydraulic oil 14 litres of HLP 32 are required.
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
the synchronous running system does not func-
tion properly.
This procedure must always be completely car-
!
ried out. This means, first fill and then vent. Cor-
rect method of filling and balancing (lift with Hy-
perFlow system).
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.
• By activating (1) the operating lever, raise the lift
approx. 1 m and then lower it completely.
• By pulling the operating lever more (approx. 10
– 15 s) in the lower position a large part of the air
already escapes from the system.
• Raise the lift (without load) by activating (1) the
operating lever to its maximum height.
• Push and hold the operating lever for another 60
seconds so air can escape from the system and
the overflow procedure equalises the drive rails to
each other.
• The oil flows from the hydraulic pump through the
command and downstream cylinders and back
into the tank.
• After releasing the operating lever, the lift lowers a
few millimetres and closes the overflow openings.
• The system is now vented and smooth operation
can happen.
• The lift now has its normal operating function.
• Afterwards lower the lift to its lowest position. Acti-
