The below instructions indicate step by step how you ensure a trouble-free installation and a satisfactory operation. It is
therefore of VITAL IMPORTANCE that you take the necessary time and care in order to ensure that the installation
tolerances are not exceeded, otherwise the lift will not function effectively, and you will not benefit fully from your
purchase of the lift.
NB: IF THESE INSTALLATION INSTRUCTIONS ARE NOT FOLLOWED STRICTLY, THE LIFT IS NOT COVERED BY
WARRANTY.
INFORMATION FOR CONSTRUCTION ENGINEER OG ARCHITECT
To allow full use of the lift capacity, the strength of the concrete floor or foundation should fulfill the following
specifications:
a) Load capacity: min. 550 kp/m² - 5500 N/m²
b) Surface spot load: 3.5 kp/cm² - 350 kN/m²
c) Extraction load for expansion bolts: 1330 kp/bolt –13,3 kN
INFORMATION FOR FITTER
The accessory kit consists of a number of small plastic bags with a number printed on each of them. This number will be
pictured by a small numbered bag. Do not, therefore, mix the contents of the different bags.
EXPANSION BOLTS: order No. for set 776898 (not included in the delivery).
Levelling plates (see page 9-10) are to be ordered in the necessary quantity on part number 502199.
NB: Note this arrow . The lift will throughout these instructions be shown from the drive-on direction (see picture 1)
Please note the designations “front” and “back” compared to the drive-on direction, and the numbering of the posts –
these designations will be referred to in the installation manual.
The below picture shows where each switch is to be fitted on the lift. There will therefore be refered to this picture all
along the manual.

NOTE ! Find the highest of the 4 corners - maximum permissible difference in height between highest and lowest corner
is 10 mm. The difference should be taken into account when installing the posts so that the lower posts can be shimmed
up underneath the base plate to ensure that the lift is horizontal.
Remove transportation device around platforms.
2. Pull cables and push cross beams in position under platform.
3. Fit platforms on cross beams by means of screws, washers and nuts (bag 2).
4. Fit adjustment screws M12x55 (bag 5). Check that cross beams are plumb. If not, adjust cross beams.

36. Pull the five-core electric cable with earth from top of post (or bottom) and out of post. Connect electric motor
in terminal box as shown.
Important ! Connect to correct voltage.
37. Electric connection of the lift as shown must only be performed by an authorized electrician (electrical
diagram in the control box).
Activate main switch and push UP-button; if pump does not deliver oil (lift does not rise), interchange two
phase wires in control unit (se above).
If air is also blowing out at the ratchet in control post, interchange hoses A and B (see item 33).
38. Adjust the pre-fitted black sliding guides by pushing them as far towards the post as possible. Fasten the
sliding guides.
39. Fit switches S11, S12 and S14 on wheel-free cross beams as shown with M4x40 taptite (bag 15).
Use the distance pieces provided with the lift to adjust each switch in the following way:
S11 and S12 are to be adjusted so that they are activated when the wheel-free cross beam lowers, but de-
activated when the wheel-free cross beam and the main cross beam are at the same height.
S14 is to be adjusted so that it is constantly activated (closed) when the free-wheel cross beam and the main
cross beam are at the same height.
