8.3 Assembly instructions
1) Remove the packaging and take out the box with the accessories and cover plates. Read and understand
the operating instructions before proceeding.
2) First you have to put a support between both columns or lift one of the columns with the help of a
lifting tool. Then remove the upper screws from the frame.
Attention: Please take special care that the column cannot fall down. The accessories could be damaged or
people could be injured.
3) After removing the first column, place a support under the lower column. Then remove these screws
from the transport frame.
4) Set up both columns. Align the main and secondary columns with each other (outer edge of base plate
to outer edge of base plate approx. 3436mm).
a) After unpacking, you must decide where you want to place the column with the power supply, the
control unit and the release.
b) Set up one column, place the drive-over plate against this column and determine the exact
distance by setting up the second column and placing it against the second side of the drive-over
plate.
5) First attach the main column, then the secondary column.
a) Drill the holes in the foundation for each ground anchor using a percussion drill. Drill perpendicular
to the ground level.
b) Remove dirt and dust carefully after drilling (vacuum and blow out if necessary).

installing the steel cables
c) The carriages must be level with the ground before proceeding.
d) Pull in the steel cables as shown in the following illustration.
e) The steel cables must be set "tight" on both sides of the column. Make sure that during a later test
run the safety catches on both sides can be heard synchronously. If this is not the case, the steel
cables or a steel cable must be retightened.
f) The ropes must always be secured against unintentional loosening (locken off) and oiled with
WD40 to ensure a long service life.
Caution: After adjusting the steel cable tension, the adjusting nuts on both sides of the column
must be locked with another nut!
9) Mount the operating control unit on the control box

9. Commissioning
9.1 Safety precautions
a) If the safety devices are defective or show any abnormalities, the lifting platform must not be
operated under any circumstances!
b) Check all connections of the hydraulic lines for tight fit and proper functioning. If there are no
leaks, a lifting operation can be started.
c) Only the operator should be near the lift during a lifting or lowering operation. Always ensure that
there are no persons in the danger zone.
d) Vehicles should always be aligned so that the vehicle's center of gravity is centrally located
between the lift columns. If this is not the case, the lift should not be used. Otherwise, neither we
nor the intermediary dealer, if any, will accept responsibility for any problems or damage caused as
a result.
e) When the desired lifting height has been reached and the safety catches are engaged, switch off
the power supply to the lifting platform before starting work in order to avoid incidents caused by
unintentional operation by other persons.
f) Make sure that the safety catches are engaged before starting work on or under a vehicle. No
persons should be in the working area of the lift during the lifting and lowering process.
