7.17 Maintenance and repair
Maintenance and repair work on the pump should only be carried out by trained service personnel, who
should have read and understood this manual prior to installing, operating or servicing this equipment.
Inform operating personnel before starting maintenance and repair work. Protect all plant parts and
operating media connected before and after the machine, such as compressed air and hydraulics, against
unintentional start-up. In all maintenance, inspection and repair work, switch the machine off and secure
the main switch against unintentional start-up.
Secure larger assemblies carefully to lifting gear. Check loosened screw connections for firm seating. Use
only original spare parts.
After maintenance work is finished, check the safety devices are functioning.
