the top edge of the floor. For an existing concrete floor the dowels have to be chosen
according to pic. 8. If floor tiles are on the concrete floor, the dowels have to be chosen
according pic. 9. 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 aggregate in the floor.
• Tighten the dowels with the dynamometric key.
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.
• Equalize the lift, if this is necessary.
• Mount the covers: Do not damage the cables.
9.3 Deaerate the hydraulic system (main lift)
• The correct power supply, the correct hydraulic oil and the closeness of the hydraulic
system have to be controlled after the installation of the lift.
By connecting the hydraulic hoses, air might enter the hydraulic system and provoke
problems of ganging. In consequence a Ventilation is necessary.
Check again the correct installation of the hydraulic hoses!
Effects, which make a Ventilation necessary are e.g. a sudden lifting out of the lowest position
or unequal rails.
Correct Ventilation:
There have to be 14 litres of hydraulic oil filled in the oil tank.
• Choose the main lift at the reversing switch (see pic.1)
• Open the vent screws on the top of the slave cylinders a little bit.
Do not open them completely.
• Push button „lifting“. The air streams out of the borings on the slave cylinders. Keep the
screws open until only hydraulic oil comes out of the borings. Close the vent screws
afterwards.
