3. Position the filter trough 1 at the edge of the pond with the
water outlet facing the water.
The filter trough must not be more than 50 cm above the
surface of the water.
The best suction results are achieved when the filter trough
is at exactly the same height as the surface of the water.
4. Press the red adjuster c in the direction of the arrow and
adjust the feet 5 so that the filter trough 1 is tilted slightly
towards the surface of the water.
5. Immerse the suction filter M of the suction unit L completely
in a calm part of the pond (clear water).
6. Push the nozzle attach-
ment N you require onto
the handle / nozzle holder
J turning slightly.
a) Adapter nozzle
for cleaning surfaces
b) Adapter nozzle
for narrow places
7. Push the combisystem handle O onto the handle / nozzle
holder J and tighten the locking screw D .
Adjust the working angle to suit the pond you are working on.
8. Fill the GARDENA Garden Pump Art. 1426 provided in the
Pond Silt Remover Set with 2 litres of water. (Operate other
pumps according to their operating instructions.)
9. Switch on the pump.
10. Hold the adapter nozzle N completely under water at
the place you want to begin drawing in water, so that the dirty
water hose
I lies flat along the bottom of the pond.
To prevent blockages, move the adapter nozzle in small,
lifting movements.
The best cleaning results are achieved from the Pond Silt Remover
once the pockets of air in the dirty water hose have dispersed.
If the water level rises in the collecting basket 4 , remove and
empty the basket and clean the filter (see 6. Cleaning).
You may have to empty the collecting basket several times
depending on the size of the pond and the amount of dirt in the
water.
Avoid kinking the hose to prevent the dirty water hose blocking up.
The collecting bag P should be used when drawing off pond silt,
in order to achieve a better filter performance.
1. Remove the collecting basket and if necessary the filter sieves
of the filter tub 1 .
2. Pull up the collecting bag P from the rear on the filter trough 1
and stretch with the elastic strip cord Q .
3. When a build up of water occurs in the filter trough, loosen the
collecting bag P from the filter trough 1 and empty it.
Depending on the degree of pollution and the pond size, the
collecting bag
P must be emptied several times.
