2 Safety regulations
ENGLISH 4
xNever use the device if any part of it is unsafe or
if it is not in an overall condition that makes it
safe to use. Before using the device always
check whether it is safe to use according to
section 6.1.
xImmediately replace damaged parts. Only use
genuine SOLO replacement parts.
xOnly use accessories and add-on parts that
have been supplied and specifically approved for
installation on the device by us.
xThe quality of any spare parts used is also an
important factor in ensuring that your device is
reliable and safe to use. Always use genuine
SOLO replacement parts, as these are the only
parts that have been manufactured with the
same equipment and under the same conditions
as the parts originally fitted to the device. This
ensures the highest possible level of quality and
accuracy of fit – vital factors in ensuring the
safety, reliability and proper functioning of your
device. Genuine SOLO replacement parts and
accessories are available from your authorised
SOLO dealer.
xHe also has access to the necessary spare parts
lists, from which the required part numbers can
be taken, and he will also be kept up to date

the range of parts on offer. Please note that the
use of non-genuine replacement parts will
invalidate your warranty.
xWhen the device is not being used it should be
safely stored in a place where it will not
endanger the health and safety of others.
Prepare the device for storage according to
section 6.7. Ensure that the device is stored in a
safe place where unauthorised persons cannot
access it.
2.3 Safe handling of spraying agents
xAvoid contaminating the environment, the mains
water supply and/or public sewer systems with
spraying agent or cleaner!
Ensure to avoid contamination when mixing,
filling, using, draining, cleaning, servicing and
transporting by using adequate procedures and
suitable containers.
xSpraying agents and cleaners must never be
allowed to enter the mains water supply – not
even by back-suction when filling, 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 spraying
agent is drawn back into water pipes. Spraying
agents and cleaners and any unused leftovers of
spraying agents and cleaners 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.
xAvoid any direct contact with spraying agents.
In case of contact with health hazardous spray-
ing agents, immediately rinse the affected body
parts with plenty of clean water, immediately
change the clothing soaked with spraying agents
and immediately seek medical advice.
xNever eat or drink when handling spraying
agents.
xStop working immediately if you start to feel
unwell while working, or if you become unusually
tired. Seek medical advice if the condition
persists.
xNever allow children or anybody who is not
familiar with handling this type of spraying agent
to handle the spraying agent.
xClean the spraying agent tank and all other
spraying agent carrying parts whenever the
spraying agent is changed. To flush out any
residue from the pump and the hose, run the
backpack sprayer with clean water after cleaning
the spraying agent tank and before the next
spraying agent is filled in. This will prevent the
risk of any chemical reactions taking place
between the different substances.
xNever spray in narrow or enclosed spaces –
spraying agents 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.
xWhen you have finished spraying, prepare the
device for storage according to section 6.7,
thoroughly wash your face and hands with soap,
take off your work clothing and ensure that it is
washed regularly.
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.
2.4 Transportation of the device
xTo prevent damage and to eliminate potential
hazards for other road users, use secure lashing
equipment to secure the device and prevent it
from tipping over and falling when transporting it
on a vehicle.
xTake appropriate measures to ensure that the
spraying agent cannot leak or spill. Check the
spraying agent tank and all hoses and pipes that
carry the spraying agent for leaks.
Before transporting the device you should ideally
prepare the device for transportation according
to section 6.7.
2 Safety regulations
ENGLISH 5
2.5 Work clothing /
personal protection equipment (PPE)
Always wear suitable protective clothing in
accordance with the relevant regulations. The
clothing must protect all parts of your body against
contact with spraying agents and against objects
that are kicked up – i.e., protective gloves, face
protection (e.g., protective goggles), protective
footwear, body protection (e.g., rubber apron), if
required breathing protection.
xClothing should be appropriate – i.e., tight-fitting,
but not obstructive.
xWear protective shoes with good grip, preferably
safety shoes.
xWear protective gloves with non-slip
palms.
xWear face protection (e.g., safety goggles)
against the spraying agents.
xAlways wear a breathing mask when
working in dense and tall plants, in
greenhouses, in dips in the ground or in
trenches and when using dangerous
spraying agents.
xImmediately change any clothing that becomes
soaked with the spraying agent.
xWash the work clothing regularly.
xNever wear a scarf, tie, loose jewellery or other
items of clothing that could be caught in a bush
or on a branch.
2.6 Before and during work
xEvery time before you start using the device,
check the entire device to ensure it is safe to use
according to section 6.1.
xCheck the spraying agent tank and all hoses and
pipes that carry the spraying agent for leaks.
xNever 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.
xThe device must only be operated by one
person at a time. Nobody else must be
within a radius of 15 metres [approx.
16 yards] at the same time.
xWhen starting to pump, ensure that the shut-off
valve is closed. Point the spray tube towards a
free area.
xAlways ensure that there is an adequate air
change when working in restricted conditions, in
tight, tall plant growth, in greenhouses, in dips in
the ground or in trenches.
xAlways remain within calling distance of other
persons who could help in the event of an
emergency.
xTake breaks at regular intervals.
xNever eat or drink when using spraying agents.
xNever smoke in areas where you are
working.
xWhen removing the spray tube, do not point to
yourself or other persons with the end of the
tube.
2.7 Maintenance and repairs
Only perform maintenance work and repairs by
yourself if they are covered in these operating
instructions. All other work must be carried out by
required training, experience, and equipment at his
disposal to provide you with the most cost-effective
solution and can help you in many ways with
advice and service.
xThe device must not be serviced, repaired
or kept in the vicinity of naked flames.
xAlways depressurise the device before doing
any maintenance work or repairs.
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.
xAlways depressurise the device before
unscrewing the high-pressure hose, the shut-off
valve, the spray tube and the nozzle attachment.
xAll repairs must only be performed using

4 Mixing spraying agents and filling the spraying agent tank
ENGLISH 8
4 Mixing spraying agents and
filling the spraying agent tank
When handling the spraying agents, always
follow the safety instructions of these
operating instructions (pay special attention to
section 2.3) and the information provided by the
manufacturer of the particular spraying agent.
Spraying agent volume:
Mix the spraying agents according to the
instructions provided by the manufacturer of the
spraying agent. Choose the appropriate volume
according to requirements.
Mixing spraying agents:
Only mix spraying agents out in the open. Never do
this inside living spaces, stables or in storage
spaces that are used for food or animal feed.
Never mix the spraying agent directly in the
spraying agent tank.
Spraying agents in powder form:
xMix the spraying agent in a separate container,
not in the spraying agent tank.
xEnsure that the mixture is thoroughly mixed
before pouring it into the spraying agent tank.
xUse the spray tube to thoroughly mix the
spraying agent in the tank.
Liquid spraying agents:
xFill 1/4 of the spraying agent tank with clean
water.
xPre-mix the spraying agent with clean water in a
separate container according to the instructions
provided by the spraying agent manufacturer.
xPour the pre-mixed spraying agent into the
spraying agent tank.
xTop up with the required amount of clean water
according to the manufacturer's instructions.
xUse the spray tube to thoroughly mix the
spraying agent in the tank.
When using spraying agents that have been mixed
from herbal preparations, the liquid needs to be
pre-filtered.
Filling the spraying agent tank:
When filling the spraying agent tank always use the
filling strainer located in the filler neck of the
spraying agent tank and observe the total filling
process.
Avoid any direct contact of the filling hose and the
contents of the spraying agent tank.
Fill level markings are applied to the side of the
spraying agent tank.
When filling up the tank, ensure that you do not fill
above the top marking (maximum fill volume).
Never allow the spraying agent tank to overflow or
public bodies of water, rainwater drains or sewage
drains to become contaminated.
Immediately wipe up any spilled spraying agent.
Identification of the tank
contents:
Attach the relevant
sticker to the spraying
agent tank to indicate the
contents of the tank (i.e.,
herbicide, fungicide or
insecticide).
The designation of the
spraying agent used has
to be attached to the
device and has to be
updated every time when
the spraying agent is
changed.
CAUTION:
Never fill different spraying agents into the
spraying agent tank without first thoroughly
cleaning the tank and all parts that come into
contact with the spraying agent and flushing the
system with plenty of clean water.
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).
5 Using the backpack sprayer
ENGLISH 9
5 Using the backpack sprayer
Ensure that you follow all of the safety
instructions when using the backpack
sprayer.
Every time you use the backpack sprayer, first
check it all over to ensure it is safe to use
according to section 6.1.
5.1 Spraying
xWhen applying spraying agent, ensure by using
appropriate measures and procedures that the
unintended release of agent to other areas is
minimized and the drift to the surrounding areas
is prevented.
xAlways proceed with the greatest care when
spraying.
xNever use the device under windy conditions or
if it is raining, as this would risk widespread
drifting of the spraying agent.
xCheck the wind direction before starting work
and select the spraying direction downwind of
the user.
xIt is best to perform spraying work in the morning
or evening, as it tends to be less windy then.
xEnsure that you only wet what is in fact intended
to be covered with spraying agents.
xNever spray the agent towards persons,
animals, open windows or doors, cars or
anything else that could be damaged by the
spraying agent.
xUse the spray nozzle suitable for your
application. Applicable nozzles: See section 9
xWhen spraying, ensure that the spraying agent
is applied evenly and homogeneously to the
treated area.
Pumping and spraying:
Prime the pump with a few quick up and down
strokes of the pump lever.
Hold the spray tube at the shut-off valve in your
hand.
Start the spraying process by pressing the shut-off
valve (a).
Releasing the shut-off valve stops the spray
process.
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 can be rotated in the shut-off valve
– after loosening the threaded collar– this is useful
for spraying under leaves.
If the spraying agent is not applied properly, spray
nozzle or filter element could be blocked or
damaged. If necessary, clean or replace the nozzle
and the filter element.
Cleaning: See section 6.7
Replacing the spray nozzle and the filter element:
See section 6.4
5.2 Residual spraying agents /
finishing spraying
Stop spraying 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 200 ml
[6.8 oz]. If you do not want to add more spraying
agent and wish to stop spraying instead, dilute this
leftover amount with two litres [68 oz] of clean
water and spray it on the treated area.
When you finish working, prepare the device for
storage according to section 6.7, thoroughly wash
your face and hands with soap, take off your work
clothing and ensure that it is washed regularly.

6 Maintenance, cleaning and storage
ENGLISH 11
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:
xTightness of all equipment components at
maximum permissible pressure with open and
closed shut-off valve
xFunction of all active components
(shut-off valve, pump lever)
xDosing 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.
Changing the spray nozzle or the filter element:
xRinse the nozzle attachment with clean water.
xDisassemble the nozzle attachment.
xClean 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!
xReplace the previous nozzle by the new nozzle
or the previous filter element by the new filter
element.
xReassemble 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
(only425Comfort,435Comfort,
425Pro)
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.
