ENGLISH 4
5.4 Operating Hints
 While running, the engine produces toxic exhaust gas which is odourless and invisible. Never start or
operate the machine in closed rooms. Ensure for adequate ventilation in confined areas such as
ditches or dips.
 No other persons should be present within a circle of 15 meters from the operator.
 Keep persons and animals away from areas in which you are working. Never spray in the direction of
other persons, animals or objects that could be damaged as a result. Bear in mind that the liquid
emerges at high speed from the spray tube. Objects could be kicked up as a result, and this could in
some cases represent a risk. The user is responsible for any hazards or accidents involving other
persons and/or their property.
 Never operate on unstable ground. Watch out for any obstacles such as tree stumps, tree roots,
ditches, etc.
 Take special care while working along slopes.
 Never touch a hot exhaust.
5.5 Irregularities, incidents, accidents
 In case of irregularities, leaks, visible damage or reduced efficiency, do not commence work, but leave
the unit from a dealer check.
 When irregularity, leaks or malfunctions occur during operation, turn off the stop switch immediately
and put the machine on the ground immediately. The device may only be used again if it is checked by
a specialist workshop and the cause of the fault has been eradicated.
 In case of serious disturbances or accidents during operation of the unit as smoke, strong odors from
the device or the device is in flames instantly remove the unit from your body and take a safe distance.
In case of fire, you have to call the fire department immediately.
5.6 Safe handling of spraying agents
 Avoid 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.
 Spraying 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.
 Avoid any direct contact with spraying agents. In case of contact with harmful pesticides rinse the
affected body parts immediately with plenty of water, any clothing soaked with spraying agents should
be changed immediately, seek medical advice if needed.
 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 spraying agent tank and all other spraying agent carrying parts whenever the spraying agent
is changed. To flush out any residue from the agent tank and the hose, run the device 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.
 Never use the device 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.
 When you have finished working, prepare the device for storage according to section 13.5 / section
13.6, 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 hoses, filters and seals.

9. Fuel information
A high performance two-stroke engine operated
with a petrol:oil mixture (petrol + oil = fuel mixture)
or with a special fuel mixture for two-stroke
engines available from specialists powers this
machine.
We recommend the proprietary “Aspen 2-takt”
special fuel mixture. Please observe the special
fuel manufacturer’s instructions.
Information on individual mixing of the fuel mixture
The fuel mix must be formed from the following
components:
 Lead-free regular petrol or lead-free super petrol
with a minimum octane number of 92 RON.
 Branded 2-stroke engine oil corresponding to
the standard ISO-L-EGD or JASO FD
Recommendation:
Use the "SOLO Profi 2-stroke engine oil" at a
mixing ratio of oil:petrol of 1:50 (2 %).
Store the fuel mix no longer than 3 weeks.
Mix table for fuel mix:
Unsuitable petrol or deviations in the mixing ratio
may lead to serious engine damage!
 Smoking or open flame is prohibited
 Allow engine to cool before re-fuelling
 Fuel may contain solvent-like substances.
Avoid skin and eye contact with mineral
products. Wear gloves while refueling.
Frequently change and clean protective
clothing. Do not inhale fuel vapors.
 Do not spill fuel or oil. In case of spillage,
immediately wipe off mistblower. Do not allow
fuel mix to contact clothing. If fuel mix is spilled
on clothing, change clothing immediately.
 Ensure fuel or oil do not contaminate soil
(environmental protection). Always use a
suitable protective soil cover.
 Do not re-fuel in unventilated rooms. Fuel
vapors collect at ground level (danger of
explosion).
 Transport and store fuel and oil only in
approved and clearly marked containers.
Children should have no access to fuel or oil.
 Ensure you do not inhale exhaust fumes while
using the machine. The use of the motorized
mistblower is prohibited in closed rooms.
The handling of fuel requires caution and
consideration. It is imperative that all safety
instructions are observed! Only refuel when the
engine has been stopped!
 Clean the area around filler inlet before
refueling.
 Remove tank lid and fill fuel mix up to the lower
edge of the filler neck. Do not overfill. If
possible, always use a fuel funnel with filter.
 Fill in card fully to avoid spilling of fuel or oil.
 Replace and secure fuel tank lid.
10. Filling
When handling the spraying agents, always follow
the safety instructions of these operating
instructions (pay special attention to section 5.6)
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.
When using spraying agents that have been mixed
from herbal preparations, the liquid needs to be
pre-filtered.
For filling the equipment, always use the strainer
inside the filler neck and observe the filler area
through the filling process.
The strainer has a mesh size of 0.5 mm. Only use
original SOLO strainers, part no.: 15137 with
standard mesh size.
Avoid any direct contact of the filling hose and the
contents of the spraying agent tank.
Fill level markings are applied to the backside 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.

ENGLISH 7
Fig. 10
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.
Never use aggressive, acid- or solvent-containing
cleaning agents (gasoline for example).
11. Starting / Stopping the engine
 Before every use and before every start of the
mistblower check and ensure the machine is in
good and safe condition. (throttle operation,
ignition switch, safety devices, shoulder strap
and check for fuel leaks)
 During the starting procedure and while
operating the mistblower, the operator must
have secure footing and have a safe body
position.
 The engine starting site should be at least 3
meters away from the refueling site.
Starting with cold engine
 Switch ignition switch to ”I” position and close
liquid tap.
Fig. 11
Close choke with choke lever (10).
 Press primer (11) several times until fuel is
visible in the primer.
 Hold the device down with your left hand. Place
a foot on the base additionally if necessary. With
the right hand, slowly pull out the starter
handle (7) until resistance is felt. Then pull
quickly and forcibly until the engine attempts to
start (engine fires).
If the engine "tries" to start (ignite), set the
choke in the middle position (partially open)
and if necessary repeat the starting procedure. In
very cold ambient temperature, let the engine with
the choke in the middle position (partially open)
warm up briefly.
As soon as the engine runs smoothly, set the
choke in the open position.
Starting with warm engine after short stop
 Start the engine with choke in open
position.
Shutting off engine
 Release throttle lever.
 After full load running bring the engine to idle for
20sec to cool down.
 Move ignition switch to ”Stop” position.

Note: The liquid pump attachment comprises a
special metering body, which should be installed
when using a liquid pump.
Please note: When using a liquid pump,
ensure that the tank contains sufficient
liquid. The liquid pump can sustain severe
damage, if it is permitted to run dry. When
using the equipment as a mister and as blower,
remove the pump for that reason.

ENGLISH 8
12.2 Spraying
 When 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.
 Always proceed with the greatest care when
spraying.
 Never use the device 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
and select the spraying direction downwind of
the user.
 It is best to perform spraying work in the
morning or evening, as it tends to be less windy
then.
 Ensure that you only wet what is in fact intended
to be covered with spraying agents.
 Never spray the agent towards persons,
animals, open windows or doors, cars or
anything else that could be damaged by the
spraying agent.
Spraying:
Approach the target object with the engine at
idling speed. Accelerate to full engine speed, then
open formula on-off tap.
Wide-range nozzle (18):
Fig. 12
When spraying plants and trees we recommend
fixing the wide-range nozzle (18) onto the red
standard nozzle (15). This ensures that a large
area can be sprayed at one time. Push the wide-
range nozzle onto the standard nozzle, until the
bead engages.
In narrow spaces and for aftercare, we
recommend placing the wide-angle grille (18a)
onto the wide-range nozzle (18). This ensures that
the spray velocity is reduced and the spray is
applied more widespread, to prevent damage to
leaves.
12.3 Residual spray medium
Switch off the appliance as soon as no further
liquid is expelled, when the metering body is
correctly positioned for spraying, or air bubbles are
visible inside the lance supply hose.
The tank will then contain less than 100 ml residual
medium.
If you don’t want to refill the tank with spray
medium and you want to terminate spraying, dilute
the residual medium with 2 l of water. Dispose of
this solution on the treated area.

ENGLISH 9
13. Maintenance and care
Any cleaning, maintenance or repair jobs should
only be performed when the engine is stopped and
with removed spark plug cap.
The exception, of course, is carburetor tuning.
Any service jobs, other than those described in
this manual, should only be carried out by an
authorized service center. Only original parts may
be used for any maintenance and service work.
Never modify your motorized mistblower – your
personal safety is at risk.
Never service or store the machine near an open
flame.
Regularly check the fuel tank lid for sealing and
tank ventilation. Only use recommended spark
plugs. Check ignition cable for any damage.
After a running in period of approx. 5 hours, all
accessible screws and nuts (except for carburetor
mixture adjustment needles) have to be checked
and re-tightened if required.
Never operate a motorized mistblower with a
damaged muffler or without muffler (fire risk and
risk of damage to hearing). Do not touch hot
muffler.
13.1 Air Filter Maintenance
The air filter separates and retains dirt before the
air reaches the combustion chamber. This reduces
engine wear.
Regular maintenance increases engine life.
Clogged air filters cause performance loss and
increased fuel consumption. This leads to a higher
toxin level in the exhaust gas and also makes
starting more difficult.
Before opening the air filter housing, close
the choke to prevent dirt entering the
carburettor.
Fig. 13
To open the air filter housing press in the black
clamp and open the housing cover downwards.
Fig. 14
Remove foam filter.
When the machine is used all day, the air filter
should be cleaned daily. In severe dust conditions
clean more often in between.
For daily cleaning:
Tap the air filter against an object or use an air
gun.
With heavy dust conditions and for normal weekly
check:
Wash a heavily soiled filter in non-flammable
cleaning solvents (warm soapy water).
Wipe the air cleaner housing clean with a dry or
slightly damp cloth. Before inserting the filter, the
housing and the filter must be completely dry
again.
Never insert moist or wet foam filters!
Immediately replace damaged filter parts.
When re-fitting, ensure the filter is positioned and
seated properly.
If the filter material is damaged, replace the
corresponding parts immediately.
Warranty claims cannot be accepted for damaged
engine parts caused by improper care and
maintenance.
13.2 Carburettor adjustment
The carburettor has been adjusted optimally at the
factory. Subject to the operational altitude
(mountains or low lying areas), the carburettor may
require readjustment.
Fig. 15
Turn the idling end-stop screw "T" to adjust the
idling speed in accordance with the details
provided in the specification. Use an engine rev
counter for this job.
 If the idling speed is too high, turn the idling
end-stop screw "T" anti-clockwise.
 If the idling speed is too low (engine stops) turn
the idling end-stop screw "T" clockwise until the
engine runs smoothly.
If the idling speed cannot be set correctly with the
idling end-stop screw "T", request an authorised
service centre to tune the carburettor.
Only qualified mechanics must adjust the
regulating screws for idle mixture "L" and full
load mixture "H".
13.3 Spark Plug
The correct spark plug with thermal range 200 is
available under the following brands:
BOSCH WSR6F
CHAMPION RCJ-6Y
NGK BPMR7A
The correct electrode gap is 0.5 mm.
Check the plug after every 50 operating
hours and replace if electrodes are worn.

ENGLISH 10
13.4 Checking the spray medium flow rate
At the beginning of the spraying season, check
whether the equipment flow rate (l/min) still
corresponds to the „Guide values“ table (see also
item „Maintenance schedule“).
For this, fill the equipment up to the maximum
marker with water, start using the equipment and
spray for one minute exactly at maximum
operating pressure. Then measure the water
volume required to bring the water level back up to
the maximum marker.
The actual volume measured represents the flow
rate of the equipment in l/min at maximum
operating pressure.
It should not deviate by more than 10 % from
those listed in the „Guide values“ table. Should the
actual value be too low, sediments inside the
metering body may be the cause. Clean the
corresponding parts and repeat the checking
procedure.
Should the actual value be too high, the metering
body may be worn or damaged. In that case,
replace the metering body with a new one (part
no.:13008).
13.5 Draining and cleaning the tank
For cleaning purposes, the tank can be fully
drained into a suitable container via the supply
hose.
For this, the engine must be cooled down.
Position the equipment onto a stable higher
support, so that the spray medium can drain into a
suitable container below.
Above the container, pull the supply hose from the
shut-off valve.
If required, tip the equipment slightly to drain the
tank completely.
Ensure that the spray medium does not run over
the equipment (especially the engine), but drains
directly into the suitable container.
Fig. 16
Dispose of residual spray medium correctly at
disposal sites licensed for specialised waste.
Empty the spray medium tank daily after work and
flush thoroughly with water.
Observe cleaning instructions supplied with the
herbicide/fungicide.
After cleaning, let the spray medium container dry
in an open state.
Fig. 17
Occasionally clean the strainer inside the filler
neck, the strainer in the accessory set and all parts
in contact with the medium, with water and a soft
brush.
13.6 Shutdown and storage
Clean the power tool after use.
 Never use aggressive cleaning solutions or
those containing solvents to clean any part of the
engine. Never hose down the engine. For best
results, simply wipe down the entire engine with
a dry or slightly damp cloth.
Store the device in a dry, safe location inside a
building (garage, basement, …). There must not be
any open fires or similar nearby. Ensure that the
device cannot be used by unauthorised persons,
especially children.
If not in use for more than four weeks, drain the
fuel tank in a well ventilated location before storing.
Start the engine with an empty fuel tank and drain
the carburettor until the engine stops. Oil residues
from the fuel mixture could otherwise clog the
carburettor jets and make it difficult to start the
device later.

14. Maintenance Plan
The following information is based on standard operating conditions.
For special conditions, such as prolonged daily use, the recommended
maintenance intervals should be reduced accordingly.
Implement all maintenance jobs regularly. If required, authorise a specialist
service centre to maintain the machine for you. The owner of the machine
is responsible for:
 Any damage caused by a lack of maintenance, incorrect or late
maintenance and repairs
 Consequential losses - including corrosion - from incorrect storage
before starting work daily weekly after the first 5 hours after every 50 hours work as required before spray season
