5.1 Safety Information
Observe all safety regulations.
All work must be done by suitably trained personnel. Maintenance or repairs
carried out incorrectly will affect the life and performance of the pump and
may cause problems when filling warranty claims.
Never mount used seals; always mount new seals.
5.2 Maintenance Intervals
The intervals stated in the maintenance schedule are approximate values for
normal pump operation. Unfavourable ambient conditions and/or aggressive

jobs.
Maintenance works must be carried out with proper tools in an adequate
work space / bench equipped with sufficient lighting.
Use only Leybold spare & consumables.
An overhaul at Leybold is recommended every 3 years.
After maintenance operations, make sure the device is in a safe condition
before putting back into operation.
