3.6 Electrical circuit diagram
Grounding according to local regulations
Before commissioning check whether the nominal
motor current matches the motor protection relay.
Check all terminal points for proper connection
and that all contact screws are tight.
Before commissioning, check all wiring and controls
for proper function. Do not permit commissioning
from the unauthorised side.
These plans were generated on a CAD system. To
keep plans to the current state, we ask that you re-
quest Nussbaum to make the changes.
These circuit diagrams are intellectual property.
They may not be given to third parties or repro-
duced without our permission!
Rights to make changes are retained.
Circuitdiagramandswitchdocuments
Circuit diagrams were made to the best of our
knowledge.
No guarantee is made for the accuracy of enclosed
circuit diagrams and switch plans contained in this
document. This is particularly relevant for switches
that were completed by us according to third party
plans. This was done by us from purchaser provided
manufacturer documentation.
Functionaltestofswitchsystems
Circuit diagrams are not standard documents.
When checking the control cabinet at the facto-
ry, eld devices such as sensors, thermostats and
motors cannot be included. For this reason, even
with careful inspection, functional and switch errors
cannot always be prevented.
Decienciesareremovedwithinthescopeofguar-
antee during commissioning. During commission-
ing,ifourservicesarenotused,thennodeciency
liability is accepted. Rework, including informing
of circuit diagrams of switch systems not commis-
sioned by us are therefore only done to an invoice
according to our service terms and conditions.
Costs for rework by third parties cannot be hon-
oured.
Safetyinspectionandsafetymeasures
The control cabinet has been produced, set up
and inspected according to recognised technolo-
gy rules according to VDE0100/0113 and accident
prevention regulation VBG4 (electrical systems and
equipment)

4 Safety regulations
When working with lifts comply with legal acci-
dent prevention regulations according to BGG945:
Comply with inspection of lifts; BGR500, operation
of lifts; (VBG14).
Particularattentionisdrawntocompliancewith
thefollowingregulations:
• The max. load carrying capacity for lifts may not
be exceeded. For this, see details on the model
plate.
• Always follow the operating manual when using
the lift.
• The lift must be completely lowered before the
vehicle is driven on, and it may only be done in
the intended direction.
• Vehicles with low oor clearance or tted with
custom devices are to be checked to see wheth-
er damage could occur before positioning the
lifting arm and raising the vehicle.
• Only personnel aged 18 or over may operate
the lift independently, they must be trained in
liftoperationandhavetheirworkveriedbythe
company. You must be explicitly tasked with the
operation of the lift. (excerpt from BGR500) (see
transfer protocol).
• The proper positioning of the carrier plate below
the vehicle is to be checked again after the vehi-
cle has been raised slightly.
• After each set down of the vehicle, check the lift-
ing arm positions below the xture points again
and adjust as required.
• When disassembling heavy, consider any possible
centre of mass shifts. The vehicle is to be appro-
priately secured using suitable materials (e.g. ten-
sioning belts, beams, etc.) against falling.
• During lifting or lowering, the work area of the lift
should be clear or people.
• It is prohibited from moving people with the lift.
• Climbing onto the lift and onto a lifted vehicle is
prohibited.
• After design and maintenance on load bearing
parts the lift must be inspected by a technical ex-
pert.
• Vehiclesmayonly be attached atxturepoints
approved by the vehicle manufacturer.
• The entire lifting and lowering process is to be
continuously observed.
• It is prohibited to set up a standard lift in explosion
endangered workshops and humid spaces (E.g.
washing halls).
• Initial access to the lift is only permitted after the
main switch has been turned off and secured,
and the operating lever is additionally secured
against unauthorised use.
5 Operatingmanual
Whenhandlingthelift,itmustabso-
lutelycomplywithsafetyregulations.
Carefully read the safety regulations
inSection4beforerstoperation!
5.1 Positioning the vehicle
Drive the vehicle onto the lift according to the following
images,untiltheliftingarmreceivesit(gureAandB).
Figure. A) The lift column must be located between the steering
wheel and the car door hinges!
Figure. B) Drive in the middle of the lift.
Swivel in the lifting arms and extend out to the de-
sired position The adjustable receiving plates are to
be placed at the pointed prescribed by the vehicle
manufacturer.
5.2 Lifting the vehicle
• Lift the vehicle until the wheels are off the ground.
Push the operating lever forwards v"Lift" (see
gure4).
• 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 xture points again
and adjust as required.

68 OPI-POWER LIFT HF 4600-HYMAX HF 4600-V2.3-DE-EN-FR-ES-IT
• 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.

5.3 Lift synchronization
• Uneven running of the lift is not possible in proper
operation.
• For this, raise the lift to its uppermost end posi-
tion. Push the operating lever for 2 more seconds.
During this procedure the lift rails are equalised to
each other as hydraulic oil ows to the tank as
anoverowfromthecommandcylinderviathe
downstream cylinder to the tank.
• Release the operating lever. The lift rails then
lower some millimetres and thereby block the
overowopeningofthecylinder.
• Both lift rails are now at the same height.
5.4 Lowering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; pull the operating lever
slowly v"Lower".
• For heavier vehicles, lift it slightly before lowering
to prevent an "sticking" and any corresponding
jolt during lowering.
• The lowering speed can be varied seamlessly.
• 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.
6 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.

6.1 Emergencydischargeduringblackout
There is the option of placing the lift into the lowest
position with a simple operation.
An emergency discharge can only be
donebypersonnelwhoaretrainedto
operatethelift.Followtheconditions
to"Lower".
Emergencydischargeprocedure
• People may not stand in the hazardous area
around the lift.
• Restrain latches.
• Slowly pull the operating lever. The lowering pro-
cedure begins immediately. Lowering speed can
be varied by the lever position.
• Always observe the lowering process.
• Lower the lift to the lowest position.
• Ifrequired,rstlyinformcustomerservice.
• Only operate the lift if it is in seamless condition
from a safety point of view again.
6.2 Moving onto an obstacle
If the lifting rails or lifting arms move onto an ob-
stacle due to operator inattention, the lift stops
in place. To remove the object, raise the lift to a
height where the object can be removed.
7 Maintenance and care of the lift
iBefore maintenance, do all preparation work
so there is no danger to life or limb or object
damage during maintenance and repair work.
Value is placed on long lifetimes and safety in
the development and production of Nussbaum
products. To guarantee the safety of the oper-
ator, product reliability, low running costs, keep
the warranty and also the long-lifetime of the
product, proper set up and operation is just as
important as regular maintenance and suf-
cient care.
iLegal principles: BSV (operating equipment
regulation) + BGR500 (Operation of work equip-
ment).
Ourplatformsfullorexceedallsafetystandardsof
the countries we supply to. For example, Europe-
anregulationsrequireaservicebyqualiedexperts
every 12 months of work of the platform. To guar-
antee the largest possible availability and function-
al capacity of the lift system, ensure the list of any
cleaning, care and maintenance work is done.
Afterrstcommissioningtheliftistobeservicedat
regular intervals of a maximum of one year by an
authorised person according to the following plan.
For intensive operation and higher degree of con-
tamination shorten the service interval.
The complete function of the lift is to be observed
during daily use. Customer service must be in-
formed of any malfunctions.

Checkthepaint:
• Check the powder coating and improve if required.
Damageby external inuences istobe treated immediately after
detection.Ifthesepointsarenottreated,inltrationofdepositsofall
kinds can cause wide-ranging and permanent damage.
These points are to be lightly sanded (120 grit), cleaned and
degreased. Afterwards, rework with a suitable touch up paint (note
the RAL No.).
• Check galvanised surfaces, touch up as needed.
White rust is fostered by permanent humidity, poor ventilation. The
affected areas can be treated by using a sanding cloth (A 280 grit).
If required, the parts are to be treated with a suitable, resistant mate-
rial (paint etc.). Check the RAL colour selection.
• Rust is brought out by mechanical damage, wear, aggressive de-
posits (de-icing salt, leaking operating uids) cleaning that is not
done or incomplete.
The affected areas can be treated by using a sanding cloth (A 280

According to manufacturer instructions, the hydraulic oil should be
changed every two years in normal operations. Various environmen-
tal inuences e.g. location, temperature swings, intensive operation
etc.,canhaveaninuenceonthequalityofthehydraulicoil.Forthis
reason, the oil must be checked during annual safety inspections and
maintenance.
The oil is used if it has a milky colour or if the hydraulic oil smells unpleas-
antly.
To change oil, lower the lift is to its lowest position then suction the oil
out of the oil container and replace the contents.
The manufacturer recommends high-quality clean hydraulic oil. The
required oil volume and type is to be taken from the technical data.
Afterlling,thehydraulic oil must bebetweentheupperand lower
markingontheoildipstick,orapprox.2.5cmbelowtheoilllingopen-
ing.
Dispose of the old oil according to regulations to the intended location
(districtofces,environmentalprotectionofceorcommercialregula-
