Safety regulations
1.3 Safe handling of spray pesticides







Pesticides must never be allowed to enter public sewer systems, sprayed onto wastelands, allowed to
drain into natural bodies of water or disposed of together with normal domestic waste. This also means
that appropriate care must be taken during filling to ensure that none of the pesticide is drawn back
into water pipes. Pesticides and any unused leftovers of pesticides must always be collected in a
suitable container and disposed of via approved facilities for household chemical waste. Please
contact your local authorities for information about your nearest disposal facilities.
Avoid any direct contact with pesticides.
Stop working immediately if you start to feel unwell while working, or if you become unusually tired.
Seek medical advice if the condition persists.
Never allow children or anybody who is not familiar with handling this type of spraying agent to handle
the spraying agent.
Clean the solution tank whenever the spraying agent is changed. Run the backpack sprayer with clear
water after cleaning the solution tank – but before the next spraying agent is filled – flush out any
residue from the pump and the hoses. This will prevent the risk of any chemical reactions taking place
between the different substances.
Never spray in narrow or enclosed spaces – pesticides are toxic and there is a risk of poisoning.
Spraying equipment must for example only be used in greenhouses if adequate ventilation is provided.
Signs must be put up in greenhouses that have been treated. Nobody should enter the greenhouse
again until it has been thoroughly ventilated.
When you have finished spraying, follow the steps in section 8.5 "Draining and cleaning the solution
tank" to prepare the device for storage, thoroughly wash your face and hands with soap, take off your
work clothing and ensure that it is washed regularly.
Any unused pesticide that is left over in the device could cause corrosion and hence damage the
device. Special attention must be paid to wearing parts like nozzles, filters and seals.
1.4 Safe handling of the rechargeable battery and the charger

The charger must only be connected to a mains supply with an operating voltage between 100V and
240V AC 50/60Hz. It must only be connected using the correct power cable - according to the countryspecific plugs.
- Check that the mains voltage is correct before connecting the device.
- Use the correct power cable - according to the country-specific plugs.
- The charger must not be connected to the mains supply in countries for which no correct power
cable - according to the country-specific plugs - is supplied together with the backpack sprayer or
in countries where the mains voltage differs from the operating voltage of the charger. In this
case you should contact a local dealer to enquire about options for connecting the charger to the
mains supply.
 Always hold the body of the plug when plugging it in and disconnecting it. Never pull it out by the
cable.
 The charger is only designed to recharge the rechargeable battery that is supplied by SOLO for this
backpack sprayer. Ensure that the battery is always correctly connected to the charger before
charging.
 Never connect the two terminals of the rechargeable battery (+ / -) with a conducting object (short
circuit).
 Keep the charger, the rechargeable battery and all of the electronics well away from splash water.
These areas should only be cleaned with a dry or slightly damp cloth. Before cleaning, always
disconnect the power plug from the socket and the charging cable from the charging socket on the
device.
 The rechargeable battery contains dangerous substances. Never open the battery or the charger.
 Only use the original charger to recharge the battery.
 The rechargeable battery and the charger must not be disposed of as normal domestic waste. Ensure
that you take them to an official disposal facility for electrical equipment.

with both pressure settings to get a feel for
using the backpack sprayer.
Never start working if there are any irregularities, if
you can see any damage to the equipment
(including the support frame) or if the equipment is
not working properly in any way. In this event, have
your device checked by a specialist workshop.
ENGLISH 11
Mixing solutions and filling the solution tank
6. Mixing solutions and filling the solution
tank
When handling the substances for spraying,
always follow the safety instructions printed
at the start of these operating instructions (pay
special attention to section 1.3 "Safe handling of
spray pesticides") and the information provided by
the manufacturer of the particular substance being
sprayed.
Additional general rules for filling the solution tank
Always ensure that the drain valve (18) is
closed before filling any fluids into the
solution tank (the lever should be set at right
angles to the hose).
Required volumes of spraying solution
Mix the solutions in accordance with the
instructions provided by the manufacturer of the
spraying agent. Choose the appropriate volume
according to requirements.
The following are guide values for plant protection:
 Plants cultivated at ground level – 0.3-0.5 l per
10 m2
 Low shrubs – 1.0-1.5 l per 10 m2
 Espalier trees, bush trees 0.5-1.0 l per tree
 Larger bush trees 2.0 l per tree
Mixing pesticides
Only mix pesticides out in the open. Never do this
inside living spaces, stables or in storage spaces
that are used for food or animal feed.
Pesticides in powder form:
 Mix the pesticide in a separate container, not in
the solution tank.
 Ensure that the mixture is thoroughly mixed
before pouring it through the filling strainer into
the solution tank.
 Use the spray tube to mix the spraying solution
in the tank again.
Markings (4) are applied to the side of the solution
tank (1) to indicate the fill level. The solution tank
has a maximum capacity of 20 litres (top marking).
When filling up with correctly mixed spraying
agent, ensure you do not fill above the top
marking.
The filling strainer (3) in the spraying agent filler
opening has a mesh aperture of 0.55 mm. Always
use the filling strainer when filling the solution tank.
Check the filling strainer before filling the tank. If
the strainer is damaged, replace it with a genuine
replacement part (part no.: 4200104) with the
correct mesh aperture.
When you are filling the tank with spraying agent,
switch the pump off, take the device off your back
and place it on a suitable surface on Never allow
the solution tank to overflow or public bodies of
water, rainwater drains or sewage drains to
become contaminated. Wipe up any spilled
solution immediately.
When filling the tank, always ensure that the hand
valve and the drain valve are closed.
Never mix the spraying agent directly in the
solution tank.
After filling, firmly close the screw cap on the filling
opening to prevent any solution from escaping.
ENGLISH 12
Liquid pesticides:
 Fill 1/4 of the solution tank with water.
 Then pre-mix the spraying agent with water in a
separate container according to the instructions
provided by the manufacturer of the spraying
agent.
 Pour the pre-mixed solution through the filling
strainer into the solution tank.
 Top up with the required amount of water in
accordance with the manufacturer's instructions.
 Use the spray tube to mix the spraying solution
in the tank again.
When using spraying agents that have been mixed
from herbal preparations, the liquid will need to be
pre-filtered before pouring it through the filling
strainer, as otherwise the strainer may become
blocked.
Mixing solutions and filling the solution tank ; Using the backpack sprayer
Identification of the tank contents

pre-mixed
Insecticide
Fungicide
CAUTION:
Never fill different spraying agents into the solution
tank without first thoroughly cleaning the solution
tank and all parts that come into contact with the
spraying agent and flushing the system with plenty
of water. We recommend the use of the special
SOLO cleaner for pesticide sprayers that is
available in 500 ml bottles. Part no.: 4900600
7. Using the backpack sprayer
7.1 Areas of application
This backpack sprayer is suitable for the purpose
of applying approved liquid pesticides, insecticides,
weed killer (herbicides) and liquid fertilizers
available from authorised specialist dealers. We
recommend using only pesticides that have been
approved for use by the relevant authorities in your
country.
The backpack sprayer can be used for applications
in agriculture, tree nurseries, forestry, fruit growing,
vineyards, vegetable growing and greenhouse
cultivation (provide adequate ventilation).
7.2 Spray nozzle / delivery rates
A flat jet nozzle (green) F 015-80 (a) is preassembled as the standard nozzle.
The following delivery rates apply to this nozzle
when it is used in conjunction with this particular
backpack sprayer:
Pump toggle switch
Delivery rates in
l/min
Setting I
0,44
Setting II
0,56
A ball valve filter (b) is fitted in the elbow piece
upstream of the spray nozzle, which minimises any
dripping from the nozzle when the hand valve is
closed. The mesh aperture of the filter is 0.35 mm.
If you need to replace the filter, ensure that you
only fit an original filter with the part no. 4900539
with the same mesh size.
ENGLISH 13
Using the backpack sprayer
7.3 Spraying
Ensure that you follow all of the safety instructions
when using the backpack sprayer.
Never use the sprayer under windy conditions or if
it is raining, as this would risk widespread drifting
of the spraying agent.
Check the wind direction before starting work.
It is best to perform spraying work in the morning
or evening, as it tends to be less windy then.
The red clip can be used to secure the hand valve
in its rest position to prevent accidental spraying.
 Carry the properly adjusted and prepared
device on your back.
 Hold the spray tube at the hand valve.
 Leave the hand valve closed when you switch
on the pump (i.e. do not pull the lever).
 Select the required operating pressure at the
pump toggle switch according to the required
range and delivery rate.
In setting II the pump automatically switches off
when the operating pressure is reached at the
hand valve. If the pressure drops while spraying
then the pump will automatically switch back on
again. This arrangement ensures that the full
capacity of the rechargeable battery is used in
the best possible way.
In setting I, the switch-off pressure may not
always be attained even if the hand valve is
closed, and the pump will then run continuously
as a result. In this case we recommend
switching the pump off manually via the toggle
switch during breaks in spraying.
Always completely switch off the pump via the
toggle switch before extended breaks or at the
end of spraying.
 Pull the hand valve lever (a) to spray.
ENGLISH 14
For this, pull the lever slightly away from the handle
(a) and lock the clip (b).
Never spray towards open windows or doors, cars,
animals, children or anything else that could be
damaged by the chemicals being sprayed.
Always proceed with the greatest of care when
spraying.
Ensure that you only cover the intended areas.
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.
7.4 Residual solutions / finishing spraying
Switch off the pump immediately when any air is
sucked in and sprayed out through the nozzle. This
is indicated by a mist being sprayed from the
nozzle. At this point the solution tank will still
contain a residual amount of less than 50 ml. If you
do not want to add more spraying agent and wish
to stop spraying instead, dilute this leftover amount
with one litre of 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 hand valve to discharge any residual
quantities of spraying agent left in the highpressure hose.
Never allow the pump to run with an empty solution
tank. Running the pump dry will result in pump
damage.
Switch the pump off when you finish working with
the sprayer. Follow the steps in section 8.5
"Draining and cleaning the solution tank" to
prepare the device for storage, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.

8.3 Information on using the rechargeable
battery
8.1 General operating and maintenance
instructions
When used properly, the rechargeable battery will
remain in good working order for many years. It is
important to note that the rechargeable battery
should never be fully discharged.
If the operating pressure built by the pump while
spraying 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.
If the backpack sprayer with rechargeable battery
is not used for an extended period of time then we
recommend recharging the battery once a month
with the supplied charger. This will prevent the
battery from deep-discharging.
Alternating between two batteries
We recommend purchasing a second rechargeable
battery if you need to be able to keep working
indefinitely without having to stop when the battery
is dead. Also remember to order the SOLO
charging cable, part no.: 5900789. This second
charging cable will allow you to recharge the
second battery independently of the backpack
sprayer.
When alternating between two batteries you can
use one of the rechargeable batteries to run the
sprayer while the second rechargeable battery is
recharged by the charger via the separate charging
cable. The batteries are easy to swap – simply
open the protective casing and undo the Velcro
strap. Ensure that the polarity is correct when the
cables are connected to the rechargeable battery
(see section 5.1) and that the battery is firmly
secured with the Velcro strap.
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.
Every time you use the backpack sprayer, first
check it all over to ensure it is safe to use.
8.2 Checking the delivery rate of solution
At least once at the start of every spraying season,
check whether the delivery rate of the sprayer
(measured in litres per minute) still corresponds to
the value indicated in section 7.2 "Spray nozzle /
delivery rates".
For this, fill up the tank 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 amount of
water delivered by 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 "7.2 Spray nozzle / delivery
rates".
If the actual value is too low, this may be caused
by deposits in the nozzle. Clean the nozzle and
repeat the test.
If the actual value is too high, this may be due to
wear or damage to the spray nozzle.
When checking the solution delivery rate of the
device, also check whether the nozzle is producing
an even, fan-shaped spray pattern.
8.4 Replacing the fuse
Replacement glass fuses (5x20 mm 4A) are
available to order from your local SOLO dealer
under the part no. 0084055.
To replace the fuse, release the fuse holder (14)
with a screwdriver (turn it half a turn anti-clockwise)
and then pull it out.
After inserting a new fuse, slide the fuse holder
back in and lock it by twisting it half a turn
clockwise.
If the fuse blows repeatedly have the device
checked by a specialist workshop before returning
it into use.

8.5 Draining and cleaning the solution tank
Draining the solution tank
Clean the filling strainer, the ball valve filter at the
spraying nozzle and the spraying nozzle
periodically with water using a soft brush. Do not
use your mouth to blow through the spray nozzle!
After cleaning, leave the solution tank open to dry.
 Place the backpack sprayer level on a
horizontal surface.
 Rotate the two locking buttons (17)
approximately 100° anti-clockwise to release
the protective casing.
 Open the protective casing.
 Hold the end of the discharge hose (19) into a
suitable container.
 Open the drain valve (18) (the lever should be
set parallel to the hose).
 After draining: Close the drain valve (the lever
should be set at right angles to the hose) and
reattach the discharge hose to the rear panel.
 Close the protective casing and twist the
locking buttons back in a clockwise direction
until they are horizontal.
Drain the solution tank daily after use and
thoroughly flush it with water. Please read and
observe the cleaning instructions in the
instructions for use supplied with the pesticide. We
recommend the use of the special SOLO cleaner
for pesticide sprayers that is available in 500 ml
dosing bottles. Part no.: 4900600
ENGLISH 16
8.6 Taking the sprayer out of service and
putting it into storage
Work through the steps in section 8.5 "Draining
and cleaning the solution tank" to prepare the
device for storage.
Store the device in a secure, dry and frost-free
location under a maximum ambient temperature of
35°C.
There must not be any open fires or similar nearby.
Even when the unit is not in use, regularly recharge
the battery (and the spare battery if you have one)
once a month with the supplied charger.
Ensure that the unit cannot be used by
unauthorised persons, in particular children.
