7.2 Maintenance / Service
To guarantee a constant elasticity of the pump hose it must be lubricated with Ponndorf
Special Grease every 300 hours of operation. To do this remove the casing cover and put
some grease through the opening onto the running surface of the pump hose (e.g. by
using a screw driver).
7.1 Changing the pump hose
Remove power from the pump by removing the main fuses before doing
any cleaning / maintenance / assembly operations !
It must be secured that there are no remains of the pumping medium left
in the pump hoses (medium could run out or spray).
Especially in case of aggressive and caustic media there is danger of
injuries !
