Important note
If the pressure warning switch (No. 2) and / or the pressure reservoir (No. 5) is detached with the
high-pressure pump
(No.
1)
removed, do not set down the pump upside down
(with the pressure
reservoir connection facing down).
If this is not observed
, the pump might not function after instal-
lation (air in the pump). Fast turning or shaking motions from thr normal position might make the
pump operational again.
