Ensure in each case that the personnel are informed accordingly.
For maintenance work taking place at heights of over approx. 1829 mm (6 ft.), use only ladders or similar equipment and working platforms intended for this purpose. At greater heights, the proper equipment for protection against falling must be worn.
Use only suitable lifting gear which is in proper working order and load sus- pension devices with sufficient carrying capacity. Do not stand or work under suspended loads!
Ensure that the electric motors/switch cabinets are sufficiently protected against moisture.
Use only suitable workshop equipment.
Before starting maintenance work, appoint a supervisor.
Inform the responsible personnel before maintenance work on the system is started.
Never operate the equipment when partially dismantled.
All maintenance and repair work not described in this chapter may only be carried out by Sterling service personnel or authorized personnel (appointed by Sterling).
Disconnect the equipment from mains supply before starting maintenan- ce procedures to ensure that it cannot be switched on unintentionally.
Depressurize all compressed air piping of the equipment before starting maintenance work.
