8 Using the pressure sprayer / 9 Maintenance, cleaning and storage
The red clip can be used to secure the shut-off
valve in its rest position to prevent accidental
spraying. For this, pull the lever slightly away (a)
from the handle and lock the clip (b).
The spray tube (10) can be rotated in the shut-off
valve (8) – after loosening the threaded collar.
This is useful for spraying under leaves.
If the spraying agent is not applied properly, spray
nozzle or ball valve filter could be blocked or
damaged. If necessary, clean or replace the nozzle
and the ball valve filter.
Cleaning: See section 9.8
Replacing the spray nozzle and the ball valve filter:
See section 9.4
If the operating pressure built by the pump drops
noticeably and the pump fails to get the pressure
back up to the normal operating level, stop
spraying with the current battery and recharge the
battery.
8.2 Residual spraying agents /
finishing spraying
Switch off the pump immediately when any air is
sucked in and sprayed out through the spray
nozzle. This is indicated by a mist being sprayed
from the nozzle. At this point the spraying agent
tank will still contain a residual amount of less than
250 ml [8.45 oz]. If you do not want to add more
spraying agent and wish to stop spraying instead,
dilute this leftover amount with 2.5 litres [0.66 gal]
of clean water and spray it on the treated area.
After switching off the pump, hold the spray tube
facing down towards the treated area and operate
the shut-off valve to discharge any residual
quantities of spraying agent left in the high-
pressure hose.
Never allow the pump to run with an empty spray-
ing agent tank. Running the pump dry will result in
pump damage.
When you finish working, prepare the device for
storage according to section 9.8, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.

9 Maintenance, cleaning and storage

9.1 General operating and maintenance
instructions
After running in the device for approximately
5 operating hours, check all accessible nuts,
screws and bolts to ensure that they have not
become loose. Retighten them as required.

9.2 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:
 Tightness of all equipment components at
maximum permissible pressure with open
and closed shut-off valve
 Function of all active components
(shut-off valve (8), pump toggle switch (12),
pressure gauge (9, depending on the model))
 Dosing and distribution accuracy of all the
nozzles used by measuring the spraying agent
delivery rate according to section 9.3
Never start working if there are any irregularities or
leaks, if you can see any damage to the equipment
(including the support frame), if any of the adjust-
ment settings are incorrect or if the equipment is
not working properly in any way. In this event have
the device checked by an autorised SOLO
workshop.
9.3 Checking the spray nozzles and the
ball valve filter 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. 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 setting of
the pump toggle switch.
This value must not deviate by more than 10 %
from the value indicated in section 13.
If the actual value is too low, this may be caused
by deposits in the spray nozzle and/or in the ball
valve filter or a discharged battery.
Charge the battery, 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.
