9.2 Erection and doweling of the lift
• Install the lift according to the data sheet and the foundation plan.
• Install the operating unit at its designed place. Connect the power supply.
• Connect the hydraulic, electric cable and the pneumatic lines with the operating unit. All
hoses are marked.
• Fill in the hydraulic oil, approx. 10 litres are needed. A high quality hydraulic oil is
recommended, it should be 32 cst. (e.g. HLP 32 LTD. OEST Company) After the fill up, the
hydraulic oil must be between the upper and low marking of the oil level gauge.
• Raise the Lift to a height of 1500 mm. Push the button „lifting“ until the vent screws (on the
top of the slave cylinders, see pic. 4) can be reached. Open vent screw (pan head screw
with copper seal) at the top of the master cylinder’s guide bush until the air can escape.
When oil starts penetrating screw down the vent screw again.
• Perform the equalisation of the rails as described in chapter 5.4.
• Set lift into its ratchets.
• Adjust the lift: first one base plate, than the second base plate. If there is an uneven floor
even it with metal sheets. A continuous contact between the floor and the base plate must be
guaranteed to avoid hollow spaces. Dowel the lift:
Nussbaum recommend safety dowels e.g. Liebig, Hilti, Fischer (German dowel
manufacturer) or equivalent dowels of other manufacturer but observe their regulations.
Before doweling check the concrete floor (with quality C20/25) if the concrete floor goes to
the top edge of the floor. For an existing concrete floor the dowels have to be chosen
according to pic. 10. If floor tiles are on the concrete floor, the dowels have to be chosen
according pic. 11. Its important for the trouble-free working that the base plate are clean and
the guides of the sliding block are clean and greased.
Check the adjustment of the base plates and dowel the lift: Bore the holes to fix the dowels
through the borings of the base plates. Clean the holes with pressure air. Put in the safety
dowels.
• Dowel the operating unit at the floor.
• Tighten the dowels with the dynamometric key (observe the description of the dowel
manufacturer).
Each dowel must be tightened with the demanded torque. Otherwise the normal and
secure function of the lift can not guaranteed.
Observe the regulations of the other dowel-manufacturer.
• Raise and lower the lift several times with load. Check the torque of the dowels and check
the hydraulic hoses tightness.
• Deaerate the oil volume between master cylinder and slave cylinder after several empty
lifting’s: Open the vent screw (cylinder screw with copper ring seal ring) at the top in the
guide bush of the master cylinder until air is coming in, when oil is coming close and tighten
the vent screw.
• Equalize the lift, if necessary.
• Mount the covers: Do not damage the cables.
