7. Inspection and Maintenance
Before conducting maintenance work, preparations must be made to ensure that
during maintenance and repair work there is no risk 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 the utmost availability and to ensure that the lift remains functional, maintenance
work contracts are organised between our clients and their local retailers.
A service must be performed at regular intervals of 3 months through the operator in
accordance with 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 the piston-rod using compressed air.
Grease the piston rods with a high capacity lipid (approx. 5 g of S2 DIN51503 KE2G
available from the Renolit Company.
• Check the function of the ramps and the roll-over safety device.
• Check the stripper of the cylinder.
• Clean and lubricate the moving parts of the lift (hinge bolts, sliding pieces, sliding surfaces)
grease with a multipurpose lipid (example: Auto Top 2000 LTD. Agip).
• Grease the lubricate nipples with a multipurpose lipid. (example: Auto Top 2000 LTD. Agip).
• Check all the safety devices of the lift.
Execution of the lubrication:
• The bolts of the automotive-lift must be are checked by an expert. (We recommend the
execution of the examination by a person which during a work training participated.)
After the examination the hinge bolts and bearings are to be lubricated. In the case of strong
contamination the bearings are to clean at least outwardly.
• Lubricate the movable parts. (bolts, sliding blocks, sliding surfaces)
The assigned sliding bearings are appropriate for the unlubricated operation. In case of
normal operating conditions no lubrication is necessary.
With intensified operating conditions, e.g. with the work with corrosion-aggressive media,
with strong dirt and dusty condition, with painting fog, etc. exists the danger of the corrosion
and/or the penetration of foreign matter into the bearings. An improved protection of the
bearings can be achieved by lubrication.
Therefore we recommend the precautionary lubricating of all hinge bolt bearings.
• Use a lubrication spray with good creep characteristics in case by using hinge bolts without
lubrication nipples. Inject the surfaces of the bolts.
Before spraying clean the bearings carefully at least outwardly.
During the lubrication procedure the bearing must be relieved. The relevant safety regulations
are to be considered
After the lubrication, raise and lower the automotive-lift several times without load.
