ENGLISH 10

5.3 Changing the spray nozzle and the

filter element

Only the spray nozzles listed in section 10 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. 3).

Before pulling on the pressure relief valve (4), 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.

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 cap gasket

Fig. 10:

For proper sealing of the

spraying agent tank, the

cap gasket (10) must be

well greased with silicone

grease.

5.5 Greasing the pump piston sealing ring

If the pump is hard to operate, the sealing ring of

the pump piston (Fig. 7, pos. 11, part

no.: 00 62 264) should be greased with silicone

grease or replaced if necessary.

Disassembly of the pump and greasing the

sealing ring:

Fig. 4: Ensure the sprayer is empty and not

pressurised. Place sprayer securely on level

ground. If the pump is completely screwed onto the

tank, loosen the pump with 1–2 turns.

Fig. 5: Firmly hold the pump handle with both

hands and push downwards until the pump

releases from the flange housing with an audible

click. Unscrew the red flange housing from the

sprayer and remove the pump from the tank.

Fig. 6: Use a screwdriver to lever both black flange

semi-circles from the pump cylinder. The pump

piston can now be pulled from the pump cylinder.

Fig. 7: The sealing ring (11) can now be re-greased

with silicone grease or replaced if damaged.

Assembly:

Fig. 8: Place the red flange housing correctly on

the pump piston.

Push the pump piston into the pump cylinder.

Push both black flange semi-circles onto the pump

cylinder until they lock with an audible click.

Fig. 9: Place the pump cylinder securely on level

ground. Line up the red flange housing in the exact

position and firmly push the red flange housing

down with both hands onto the pump cylinder until

the parts lock together with an audible click.

5.6 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. 3).

Before pulling on the pressure relief valve (4), 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.
