in pressure hose so that air can escape during
the suction process.
6. Insert the power plug.
7. Lift and hold the delivery hose
pump, press the On/Off switch
until the pump has primed.
v If the pump does not deliver after approx. 5 minutes,
switch off the pump (press On/Off switch

Leaky or damaged suction
hose.
The pump was not filled with
the liquid to be pumped.
The liquid escapes over the
hose which is connected to
the delivery side during the
suction action.
Absolutely vacuumresistant connection is achieved by using
GARDENA Suction Hoses (see point 7. ACCESSORIES).

Air cannot escape, since
delivery side is closed or
remaining water is in the
pressure hose.

Too high suction height.
In case of any other difficulties concerning the suction action,
use GARDENA Suction Hoses with Backflow Preventer (see point

Electric failure.
Noise development in the
In the case of strong flows (e.g. open hose end, without
hydraulic area
connect ing device), noise may result in the hydraulic part of
the pump. This is harmless and does not lead to damage
of the pump. The noise can be removed by lightly changing
the flow (e.g. light opening/closing of a connecting device).
NOTE: For any other malfunctions please contact the GARDENA service depart-
ment. Repairs must only be done by GARDENA service departments or specialist
dealers approved by GARDENA.
