Oil-change
Over-used lubrication oil damages the pumps' mechanism; make sure to replace oil as soon as
it starts to turn cloudy. For conducting the oil-change, the pump must be switched off. For
changing the oil proceed as follows:
Unscrew the oil drainage plug located on the lower part of the pump
Check that oil comes out completely from the pump
Tightly screw the oil drainage plug back on
Re-fill the pump with oil (see "Filling of oil")
WARNING: Do not pollute the environment by spilling oil; the lubricant oil is a special
waste and must be disposed of according to relevant local law / guidelines in force.

placed. Only qualified service staff shall carry out such maintenance or repair work; otherwise
