7. Inspection and Maintenance of Nussbaum lifts
Before conducting maintenance work, preparations must be made to ensure
that during maintenance and repairwork there is no rist to the safety of
people working on or around the lift and also that there is no risk of damage
to equipment being used on or around the lift.
To guarantee best availability and operability of the lift, maintenance work
contracts are organised between our clients and their local retailers.
A service must be performed at regular intervals of 3 months by the operator in
accordance with the following service manual. If the lift is in continuous
operation or in a dirty environment, the maintenance rate must be increased.
During daily operation the lift must be closely observed to ensure that it is
functioning correctly. In the case of malfunction or leakage the technical service
must be informed.
7.1 Maintenance plan of the lift
 Before beginning any maintenance work, isolate the power supply. Secure
the main switch (lock it). Secure the danger area around the automotive lift
and secure the lift against unintentional lowering.
 Clean cylinder wipers and check for damages.
 Clean the plunger from sand and dirt using compressed air.
 Check electric parts for damages.
 Clean and lubricate the moving parts of the lift (hinge bolts, sliding pieces,
sliding surfaces) grease with a multipurpose lipid (i.e. Auto Top 2000 LTD.
Agip).
 Grease the lubricate nipples with a multipurpose lipid.
 Check all welded joints on the automotive-lift for cracks. If any cracks are
found on the lift, shut down the lift and call the service partner.
 Damage to external surfaces, must be immediately repaired. If theses repairs
are not made immediately, permanent damage to the powder-coated
surface may result.
Repair and clean damaged areas with an abrasive paper (grain 120). After
this is complete, use a suitable paint (observe the RAL Number).
 Check all zinc surfaces and repair them with abrasive paper (grain 280).
White rust can result from humid storage and poor aerating.
Rust may result from mechanical damage, wear, aggressive sediments (de-
icing salt, liquids) or insufficient cleaning.
Repair and clean these areas with abrasive paper (grain 280).
After cleaning use a suitable paint (observe the RAL Number).
 Check the tank level of the hydraulic oil. Refill with a clean, high quality oil
(32 cst) (i.e. HLP 32 LTD. OEST Company)
 The hydraulic oil has to be changed at least once a year. To change the oil,
lower the lift into its lowest position. Empty all tanks and refill with clean oil,
approx. 17 litres per hydraulic unit are needed.
 Use an ATF-Suffix hydraulic-oil (OEST Company) if the ambient temperature is
under 5 degrees centigrade. After filling, the hydraulic oil must be between
the upper and lower markings of the oil level gauge.
