• Check the zinc surface and repair it with a suitable tool. Use abrasive paper
(grain 280).
White rust can result from moisture laying in certain areas for long periods of
time. Poor aerating can also result in rust formation.
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 this is complete, use a suitable paint (observe the RAL Number).
• 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.
(see chapter 3.) 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.
Remove the old oil according to the appropriate regulations.
• Check the hydraulic tubes for leakage.
• It is prescribed (VBG 14, § 52-3 German regulation) to exchange the hydraulic
hose if its necessary, but latest after 6 years.
• Check that all screws and bolts are correctly torque (turning moments, see the
list)
