Positioning the vehicle

The lift must be completely lowered before the ve-
hicle is driven on, and it may only be done in the
intended direction.
Lifting arm start position
• Swivel in the carrier arm and pull out properly
to the desired length. The adjustable receiving
plates must be placed at the points specified by
the vehicle manufacturer.
• Vehicles with low floor clearance or fitted with
custom devices are to be checked to see wheth-
er damage could occur before positioning the
lifting arm and raising the vehicle.
• The lifting arm block (20) must be ratcheted in af-
ter the fixture point has been reached.

Lifting the vehicle

• Lift the vehicle until the wheels are off the ground.
Push the operating lever (9) slowly forwards =
"LIFT" (17).
• The proper positioning of the lifting arm is to be
17
checked again after the vehicle has been raised
slightly.
• Similarly check whether the lifting arm blocks (20)
are ratcheted in. Otherwise, lower the lift and re-
position the vehicle.

• After setting down the vehicle, check the lifting
arm positions for proper seating below the fixture
points before the vehicle is lifted again.
• During lifting or lowering, the work area of the lift
should be clear or people and objects.
• Afterwards, lift the vehicle to the desired working
height.

i See to it that the lifting arm blocks (20) are ratch-
eted in after the vehicle has been accepted.

Lift synchronization

• The command, downstream cylinder system ex-
cludes any unsynchronous running when operat-
ed properly.
• However, if the lift must be equalized it is sufficient
to move it to the upper end position. Push the op-
erating lever (9) for another 10 seconds.
028
• During this procedure the lift rails are equalized to
each other as hydraulic oil flows to the tank as
an overflow from the command cylinder via the
downstream cylinder to the tank (HyperFlow).
• Release the operating lever. The lift rails then low-
er a few millimetres and then block the overflow
opening of the cylinders.
• Both lift rails are now at the same height.
Ensure secure vehicle placement on
the carrier plate, otherwise there is a
danger of the vehicle dropping.
