Residual Spray Medium; Checking The Spray Medium Flow Rate; Draining And Cleaning The Tank - Solo MASTER 452 Originalbetriebsanleitung

In narrow spaces and for aftercare, we
recommend placing the wide-angle grille (7a) onto
the wide-range nozzle. This ensures that the spray
velocity is reduced and the spray is applied more
widespread, to prevent damage to leaves.

11.3 Residual spray medium

Switch off the appliance as soon as no further
liquid is expelled, when the metering body is
correctly positioned for spraying, or air bubbles are
visible inside the lance supply hose.
The tank will then contain less than 100 ml
residual medium.
If you don't want to refill the tank with spray
medium and you want to terminate spraying, dilute
the residual medium with 2 l of water. Dispose of
this solution on the treated area.

11.4 Checking the spray medium flow rate

At the beginning of the spraying season, check
whether the equipment flow rate (l/min) still
corresponds to the „Guide values" table (see also
item „Maintenance schedule").
For this, fill the equipment up to the maximum
marker with water, start using the equipment and
spray for one minute exactly at maximum
operating pressure. Then measure the water
volume required to bring the water level back up to
the maximum marker.
The actual volume measured represents the flow
rate of the equipment in l/min at maximum
operating pressure.
It should not deviate by more than 10 % from
those listed in the „Guide values" table. Should the
actual value be too low, sediments inside the
metering body may be the cause. Clean the
corresponding parts and repeat the checking
procedure.
Should the actual value be too high, the metering
body may be worn or damaged. In that case,
replace the metering body with a new one (part
no.:13008).

11.5 Draining and cleaning the tank

For cleaning purposes, the tank can be fully
drained into a suitable container via the supply
hose.
For this, the engine must be cooled down.
Position the equipment onto a stable higher
support, so that the spray medium can drain into a
suitable container below.
Above the container, pull the supply hose from the
shut-off valve.
If required, tip the equipment slightly to drain the
tank completely.
Ensure that the spray medium does not run over
the equipment (especially the engine), but drains
directly into the suitable container.

Dispose of residual spray medium correctly at
disposal sites licensed for specialised waste.
Empty the spray medium tank daily after work and
flush thoroughly with water.
Observe cleaning instructions supplied with the
herbicide/fungicide.
After cleaning, let the spray medium container dry
in an open state.

Occasionally clean the strainer inside the filler
neck, the strainer in the accessory set and all parts
in contact with the medium, with water and a soft
brush.
