4.3. INSTRUCTIONS FOR ANNUAL MAINTENANCE OF THE LIFT
The annual maintenance must be carried out every 12 months or 800 hours of operation,
whichever comes first. The measures of the smaller services need not be carried out
separately in connection with the annual maintenance as they, to the extent necessary, are
included in the instructions for the annual maintenance.
Under demanding conditions where moist, corrosive substances or corrosive climate may
speed up the deterioration of the structure and induce malfunctions, the inspection must be
performed more often and the influence of corrosion and malfunctions must be reduced by
using appropriate protective means.
Only technical specialists who are familiar with the structure and the operation of the lift are
allowed to maintain the lift.

contaminants in the system may cause malfunctions later on. Wash the lift externally.
• use pressure air to dry the electric devices, hydraulic connectors etc. before opening
them
• apply appropriate moisture repellent to the electric appliances after the drying
