Checking The Spray Nozzles And The Filter Element By Measuring The Spraying Agent Delivery Rate; Changing The Spray Nozzle And The Filter Element; Greasing The Cap Gasket; Draining The Spraying Agent Tank And Cleaning The Spraying Agent Carrying Parts - Solo 408 Instructions D'emploi

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 Maintenance, cleaning and storage

5.4 Greasing the cap gasket

To seal the spraying agent tank, always keep the
lid 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 under 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.
