5.2 Checking the spray nozzles and the filter

element by measuring the spraying agent

delivery rate

Fill up the tank with clean water to the maximum

marking, start it up and spray for exactly one

minute at an operating pressure of 1 bar.

Then measure the quantity of water required to

refill the tank to its maximum level. The value

measured corresponds to the delivery rate of the

device in l/min for the selected operating pressure.

This value must not deviate by more than 10 %

from the value indicated in section 4.1.

If the actual value is too low, this may be caused

by deposits in the spray nozzle and/or in the filter

element. Clean the parts and repeat the check.

If the actual value is too high, this may be due to

wear or damage to the spray nozzle.

When checking the nozzles, also check whether

the spray nozzle is producing an even, fan-shaped

spray pattern.

If the delivery rate is still too low after cleaning the

nozzle and the filter element, or if the nozzle and/or

the filter element are worn or damaged, replace the

nozzle and/or the filter element by genuine SOLO

replacement parts.

Changing the spray nozzle and the filter element:

See section 5.3

5.3 Changing the spray nozzle and the

filter element

Only the standard spray nozzle (part no.:

49 00 525), the spray nozzles from the nozzle kit

(part no.: 49 00 574) and the genuine filter element

(part no.: 40 74 922 25, mesh aperture: 0.8 mm

[0.031"]) must be used in this pressure sprayer.

Spray nozzle and filter element must only be

changed if the device is depressurised.

Depressurise the device by pulling on the pressure

relief valve (Fig. 4).

Before pulling on the pressure relief valve (2), the

device must always be in an upright position.

Attention: Keep the device away from your face!

Changing the spray nozzle or the filter element:

x Rinse the nozzle attachment with clean water.

x Disassemble the nozzle attachment (Fig. 2).

x Clean the O-rings, the filter element and the

spray nozzle with clean water and a soft brush

(Fig. 8). Never use your mouth to blow through

the spray nozzle! Never use hard objects to

clean the nozzles!

x Replace the previous nozzle by the new one or

the previous filter element by the new one.

x Reassemble the components of the nozzle

attachment (Fig. 2).

5.4 Greasing the pump gasket

To seal the spraying agent tank, always keep the

pump gasket greased well with silicone grease.

5.5 Draining the spraying agent tank and

cleaning the spraying agent carrying

parts

Before opening the spraying agent tank and before

disassembling the nozzle attachment, depressurise

the device by pulling on the pressure relief valve

(Fig. 4).

Before pulling on the pressure relief valve (2), the

device must always be in an upright position.

Attention: Keep the device away from your face!

Drain the spraying agent tank and all other

spraying agent carrying parts daily after use and

particularly at the end of the spraying season and

thoroughly flush them with clean water.

Any unused spraying agent that is left over in the

device could cause corrosion and hence damage

the device. Special attention must be paid to

wearing parts like spray nozzles, filters and seals.

Please read and observe the cleaning instructions

supplied with the spraying agent.

Recommendation: Use the special SOLO cleaner

for plant protection sprayers (dosing bottle of

500 ml [approx. 16.9 oz], part no.: 49 00 600).

Never use aggressive, acid- or solvent-containing

cleaning agents (gasoline for example).

After cleaning, leave the spraying agent tank open

to dry.

Cleaning the spray nozzle and the filter element:

x Rinse the nozzle attachment with clean water.

x Disassemble the nozzle attachment (Fig. 2).

x Clean the O-rings, the filter element and the

spray nozzle with clean water and a soft brush

(Fig. 8). Never use your mouth to blow through

the spray nozzle! Never use hard objects to

clean the nozzles!

x Reassemble the components of the nozzle

attachment (Fig. 2).

5.6 Taking the sprayer out of service and

putting it into storage

Prepare the device for storage according to

section 5.5.

Store the device protected from sunlight in a

secure, dry and frost-free location at a maximum

ambient temperature of 35 °C [95 °F].

There must not be any open fires or similar

nearby.

Ensure that the unit cannot be used by

unauthorised persons, in particular children.
