Lift Synchronous Running Controls; Lower The Vehicle; Behaviour In Cases Of Error - Nussbaum POWER LIFT HF 3000 Betriebsanleitung

• If the wheels are not blocked, interrupt the lifting
process and check for proper seating of the car-
rier plate. Similarly check whether the lifting arm
blocks are ratcheted in. Otherwise, lower the lift
and reposition the vehicle.
• After each set down of the vehicle, check the lift-
ing arm positions below the fixture points again
and adjust as required.
• Check that there are no people or objects in the
hazardous area of the lift.
• Afterwards, lift the vehicle to the desired working
height.
Ensure secure vehicle placement on
the carrier plate, otherwise there is a
danger of the vehicle dropping.
i See to it that the lifting arm blocks are ratcheted
in after the vehicle has been accepted.

Lift synchronous running controls

• The command, downstream cylinder system ex-
cludes any unsynchronized running when operat-
ed properly.
• For this, raise the lift to its uppermost end posi-
tion. Push the "Lift" button for another 2 seconds.
During this procedure the lift rails are equalised to
each other as hydraulic oil flows to the tank as
an overflow from the command cylinder via the
downstream cylinder to the tank.
• Release the lift button. The lift rails then lower
some millimetres and thereby block the overflow
opening of the cylinder.
• Both lift rails are now at the same height.
5.4 Lower the vehicle
• Check that there are no people or objects in the
hazardous area of the lift.
• Lower the vehicle to the desired working height
or to its lowest position; push the "Lower" button
slowly v "Lower".
• For heavier vehicles, before removing the vehicle,
slightly raise the lift before lowering to prevent any
"sticking" and corresponding jolt during lowering.

• Once the lift is in the lowest position, push the lift-
ing arms to the start position.

Once the lift is in the lowest position, swing out the lifting arms to
the start position.
• Move the vehicle out of the lift.

Behaviour in cases of error

Defective operational readiness of the lift may be
due to a simple error. Check the system for the list-
ed sources of error.
If the error cannot be removed after an inspection
to the named causes, then inform customer service
or your dealer.
Independent repairs to the lift, espe-
cially on the safety devices, as well as
inspections and repairs to electrical
systems are prohibited.
Work on electrical systems may only
be done by electricians.
Problem: The lift cannot be raised!
possible causes:
No power supply (pow-
er supply) present
The main switch is not
switched on, or is de-
fective
Repair:
Have the power supply
checked by an electri-
cian
