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.

Recycle the old oil according to the appropriate regulations.

Check hydraulic system for leakage.

Check hydraulic tubes for leakage. Hydraulic tubes need to be exchanged at least
every 6 years.

Retighten all screws and bolts (see the list below for torque).
