6. Maintenance
The GARDENA Garden Pump is essentially maintenance-free.
Flush through Garden Pump:
The pump must be flushed through after discharging chlorinated
swimming pool water.
1. Pump through lukewarm water (max. 35 °C), possibly adding a
mild cleaning agent (e.g. detergent) until the pumped water
runs clear.
2. Remove residuals according to the waste disposal laws
applicable in your area.

impeller:
➔
Turn the impeller bolt
using a screwdriver.
This will free the blocked impeller.
Problem
Pump runs, but the suction
action doesn’t take place.
Probable cause
Pump draws in air at a joint.
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 vacuum-resistant connection is achieved by using
GARDENA Suction Hoses (see point
8. Accessories
).
Leaky screw fitting
at the filler
cap
.
Air cannot escape, since delivery
side is closed or remaining water
is in the pressure hose.
The waiting time wasn’t
observed.
Suction filter or backflow
preventer in the suction hose
clogged.
Remedy
➔
Seal connections on suction
side so are airtight.
➔
Check suction line for dama-
ge and seal so is airtight.
➔
Fill the pump
(see “
4. Operation
").
1. Fill the pump again
(see “
4. Operation
").
2. When starting operation hold
the pressure hose approx.
1 m vertically above the
pump, until the suction action
has taken place.
➔
Check seal (replace if neces-
sary) and tighten connection
securely (do not use pliers).
➔
Open all possible shut-off
devices (e.g. spray nozzle) in
the pressure line, or drain the
pressure hose or disconnect
it during the suction action.
➔
Switch on the pump and wait
ca. 5 min.
➔
Clean the filter or the back
flow preventer.
