Initial operation
According to VGB 14 initial operation must be done by a specialist in the presence of the owner/user.
The specialist is obliged to instruct the owner/user in the use of the lift and to point out the dangers through
wrong operation, the safety indications according to the current law and the behaviour when faults occur.
It must be certified by the specialist in the enclosed test book.
Drive the vehicle in the middle between the two columns. Swivel the lifting arms under the vehicle and position
them under the points stipulated by the vehicle manufacturer.
Take care that the vehicle is evenly placed on all 4 carrying platforms.
In cases where our standard turntables are not suitable for the safe locating of a vehicle (i.e. offroad vehicle),
we recommend the wide range of accessories for special purposes.
Please observe the operational safety regulations.
Raising
The vehicle doors must be kept shut. Press the key “raise”( Heben) and observe the vehicle and the lift. When
the vehicle wheels have lost contact with the floor (after a height of approx. 30 cm), the lifting process must
be interrupted and the rubber turntables under the vehicle must be checked for safe positioning. Equally
important is a sight check of the lifting arm locks. The lifting process can be continued only after checking
that the automatic toothed segments of the lifting arm stopper are firmly anchored on each lifting arm/lifting
carriage. Check that nobody is present in the danger area. Press the “raise” key until the vehicle has been
hoisted to the required working height. When the lift has reached the upper end position, it stops
automatically. During the raising process neither persons nor objects must be present in the working area.
Avoid jerky raising actions.
Lowering
Check the danger area. During the lowering process neither persons nor objects must be present in the
working area of the lift or on the lifting platform.
Press the key “lower”, observe the vehicle and the lifting platform until the required height or the danger
area of approx. 120 mm above the lift base position has been reached.
At this height the lift stops automatically. If the key “lower” is pressed again, the lift can be driven back
into its base position.
During this lowering process in the danger area a warning signal tone is audible.
If one of the lifting carriages advances, so that the vehicle is out of phase, a brake on the advancing
motor will be operated by the alignment control system until the lifting carriage which is lagging behind
has reached the same level. During a working process the lift can undergo several alignments.
Jerking movement during lowering by pressing the lowering key must be avoided because this will
cause extreme oscillation of the lifting platform. When the lower end position has been reached, the lift
stops automatically and the lock of the lifting arm stopper is released automatically.
The lifting arms which are positioned under the vehicle loading points must be pushed together and
swivelled back into their base position. Drive the vehicle out of the lifting platform.
Note
The process described for the initial operation applies to each lifting and lowering process of the vehicle.
Caution: During operation, it may be noticed a burned grease odour. This is due to the high operating
temperature of the screw-nut set. This phenomenon is normal.
