6.2 Trial run

At least at the start of every spraying season and in
frequent use at least once a month, perform a trial
run with clean water to check the following:
x Tightness of all equipment components at
maximum permissible pressure with open and
closed shut-off valve
x Function of all active components
(shut-off valve, pump lever)
x Dosing and distribution accuracy of all the
nozzles used by measuring the spraying agent
delivery rate according to section 6.3
Never start working if there are any irregularities or
leaks, if you can see any damage to the equipment
or if the equipment is not working properly in any
way. In this event, immediately have the device
checked by a specialist workshop.
6.3 Checking the spray nozzles and the filter
element
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 2 bar [29 psi].
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 9.
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 6.4
6.4 Changing the spray nozzle and the
filter element
Spray nozzle and filter element must only be
changed if the device is depressurised.
To depressurise the device, hold the spray tube in
the spraying agent tank or in a suitable container
for the spraying agent and operate the shut-off
valve until no more fluid is sprayed.
6 Maintenance, cleaning and storage
Changing the spray nozzle or the filter element:
x Rinse the nozzle attachment with clean water.
x Disassemble the nozzle attachment.
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 nozzle
or the previous filter element by the new filter
element.
x Reassemble the components of the nozzle
attachment (Fig. 22).

6.5 Greasing the cap gasket

If the tank lid becomes hard to tighten or open,
apply silicone grease to the lid gasket.
6.6 Greasing the piston collar and the pump
piston pump
(only 425 Comfort, 435 Comfort,
425 Pro)
After disassembly of the pump components or after
replacing the piston collar, use water resistant
grease to lubricate the piston and the collar.
6.7 Draining the spraying agent tank and
cleaning all other spraying agent carrying
parts
Drain the spraying agent tank, all other spraying
agent carrying parts and the filling strainer 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.: 4900600).
Never use aggressive, acid- or solvent-containing
cleaning agents (gasoline for example).
After cleaning, leave the spraying agent tank open
to dry.
