Safety regulations
1.8 Working with the machine
• Only use this power tool when it is complete and in a safe condition.
As soon as the engine is running, the power tool generates toxic gases, which may be invisible and odourless. Never work with the power tool in enclosed spaces. In confined conditions such pits or excavations, ensure adequate air changes during work.
Do not smoke at the work site and in the immediate vicinity of the power tool. There is an increased fire hazard!
• Work conscientiously, thoughtfully and calmly, and do not endanger third parties.
- Pay attention to good visibility and lighting conditions.
- Always remain within earshot of other people who can provide help in case of emergency.
- Plan for timely work breaks.
- Pay attention to possible hazards and take appropriate precautions. Be aware that wearing ear defenders reduces the ability to perceive noise. This includes sounds alerting to danger such as signals, shouts, etc. that can go unnoticed.
- Exercise caution when the ground is wet or covered in ice and snow, on overhangs, or uneven terrain. There is an increased risk of slipping!
- Pay attention to the risk of stumbling and obstacles, such as tree roots and stumps, edges, etc. Pay particular attention to safety when working on slopes.
- Before commencing work, check the working area for stones, broken glass, nails, wire or other solid objects and remove such debris to prevent them being picked up and thrown out by the cutters.
- Always hold this power tool firmly in both hands, and ensure your safe and solid foothold.
- Always hold the cutters below hip level. Never lift a rotating cutter off the ground.
- Keep all parts of the body away from rotating cutters.
•
•
•
•
•
- Use a correct operating mode (see Chapter 8.3 “Correct brushcutter operation").
- Use the power tool at lowest possible noise and exhaust levels. Only open the throttle when working, do not let the engine run unnecessarily. Please note that noise also impacts on the environment.
Observe the quiet times that can vary from place to place.
- Never use blunt cutters and avoid uncontrolled contact of the cutter with debris. Otherwise there will be an increased risk of the equipment kicking, which could throw the entire machine around. As a result, the operator could be subjected to involuntary movements, which could lead to serious injury or death.
Stop the engine if you notice a difference in the operating characteristics of the brushcutter.
Due to the centrifugal clutch, the cutters will run on for a short time, even if you release the throttle.
Ensure the cutter has come to a full stop before storing the machine.
Always stop the engine before any contact with the cutter – even when clearing a blockage or if cutters have become jammed – wait until the cutter has stopped and remove the spark plug cap.
Never touch the exhaust or the silencer; as long as they are still hot, there is a risk of burns!
Never work with a defective or missing silencer. There is a hazard of hearing damage and burning!
First Aid
A first aid box should always be available on-site. Immediately replace any materials you have used:
Note:
Over exposing persons with circulatory problems to vibrations can lead to damage to their nervous system or blood vessels. The following systems may occur from vibrations to fingers, hands or the wrists:

5. Preparing the equipment for use
For shipping purposes, the brushcutter is partly disassembled and has to be reassembled prior to use.
Only use the brushcutter after it has been fully assembled.
Ensure that the tank is fully drained before any assembly, disassembly or modification.
5.1 Assembly of the handle
A) "Loop" handle for models 109L and 111L
(letter "L" in the model name)
Attach the "loop" handle approximately 5 cm - 30 cm from the strap attachment according to your preferred working position. The longer side of the handle serves as a safety barrier and must therefore always be on the side of the user:
• If you carry the brushcutter on the right hand side of your body when working then the longer side of the handle must face to the left.
• If, however, you prefer to carry the brushcutter on the left hand side of your body when working
(i.e. if you are left-handed) then the longer side of the handle must face to the right.
Fig. 2a
• Initially tighten the screws only lightly.
• Push the handle, in accordance with your body size, into its optimum position.
• Then tighten the screws.
Preparing the equipment for use
B) "Bike handle" for models 109B and 111B
(letter “B” in the model name)
Fig. 2b
• Remove quick release screw (20) with sleeve
(b) and wavy washer (c) from the handle support (19)
• Take off the two half shells (a) from the handle support.
• Position the two-handed "bike handle" (5) with the two half shells (a) on the handle support
(19).
• Insert quick release screw (20) with sleeve (b) and wavy washer (c) into the handle support, but only so far that the quick release mechanism can still flip over when the handle is sitting tight. The quick release mechanism can be flipped over to the front or rear. If the handle is not quite tight yet, tighten the quick release screw another half turn and flip the mechanism to the opposite side.
• The r.h. side of handle should be fitted as near as possible to the handle support.
• In order to adjust the handle to the perfect position, flip up the quick release mechanism and loosen the screw one turn if necessary.
• Adjust the handle and screw the quick release screw (20) back in again, then flip the quick release mechanism back over.
Note: You will have achieved an optimum adjustment, if the centre of the power tool is at the centre of your body. Your elbow should be slightly angled in operating position.
Important: Always lead the brushcutter with the bicycle handlebar on the r.h. side of the body!
Preparing the equipment for use
When assembling the guard, the damping inserts from the accessories pack must be fitted into the guard and mounting bracket in accordance with
Figures 3a - 3e below.
Fig. 3d

ENGLISH 10
Fig. 4a
• Position the brushcutter with the output shaft facing downward.
• Raise the shaft tube and slide the guard (16) along the underside of the shaft tube into the correct position (it should reach a stop at the angular gearbox).
• Lay down the shaft tube with the guard.
• First insert a 5 x 20 mm bolt through hole a to tighten the retainer (17) on the guard. Then insert the second 5 x 20 mm bolt through hole
b, tightening finger tight only at this stage.
(Note: The retainer has a raised part on the inside near hole a. This allows the first bolt (which is inserted through hole a) to be tightened straight onto the block without any risk of the connection not being straight.)
Fig. 4b
• Reposition the brushcutter with the output shaft facing upward.
• Insert the two long 5 x 35 mm bolts through the hole on the retaining bracket of the angular gearbox and tighten the guard and the retainer.
The holes must line up exactly, so it may be necessary to adjust the position of the guard first.
• To finish off, fully tighten the bolt in hole b.
Always switch off the engine, pull the spark plug cap and wear protective gloves when fitting or replacing the cutter!
Depending on your particular model, one of the following cutting tools will already be provided as standard equipment with your brushcutter. The cutting tools described below are available as genuine SOLO replacement parts which can be obtained from specialist retailers and should be installed as described below. Please refer to the overview of approved accessories in chapter 4 for more information.
A) Assembly of the 3-tooth brush cutting blade and the 4-tooth grass cutting blade
Fig. 5
• Position the brushcutter with the output shaft facing upwards.
• Place the brush cutting blade on the pressure piece (25). In order to centre the cutting blade, the shoulder of the pressure piece must be located exactly in the bore of the cutting blade.
• Fix the pressure washer (26).
• Place the nut protector (27) and turn safety nut
(28) onto the shaft.
Caution! Left hand thread - tighten counter clockwise.
Take care that all parts are centered.
• Block the shaft with the stop pin (4) and tighten nut.
It is imperative that the safety nut (28) is replaced, if it has become loose due to frequent rem oval and tightening.
Afterwards check that the cutting blade is securely seated and that it is properly centred.
Preparing the equipment for use
Transport protection for metal cutting blades
When you first purchase an approved metal cutting blade which is not supplied together with the brushcutter (see chapter 4 "Accessories"), you will also need to purchase a corresponding transport protector.
When the metal cutting blades are attached (4tooth grass cutting blade or 3-tooth brush cutting blade, provided either as standard equipment with the different models or purchased as accessories), the transport protector must always be attached to cover the blades when the device is being stored or transported, or during work breaks during which the engine is switched off.
Fig. 6
• Position the transport protector with the corresponding recess at one of the tips of the metal cutting blade.
• Press the two tabs (a) on the transport protector together to increase the internal diameter of the transport protector.
• Lay the transport protector right over the cutting tool. Position the inner shoulder (b) between the metal cutting blade and the running disc.
• Open the two tabs again, and in doing so also position the inner shoulder between the metal cutting tool and the running disc at tab (c).
When restarting work, take the transport protector back off by pressing the two tabs (a) together before starting the engine.
Preparing the equipment for use
B) Assembly of the nylon line head
Fig. 7
When fitting a nylon line head, you will not need the following components shown in Fig. 5:
Retaining nut (28) (caution: left-handed thread), nut protector (27), pressure washer (26) and metal cutting blade.
• Fit the anti-winding protection (30) (supplied with the line head) after the pressure piece (25). The side of the anti-winding protection labelled with the number "870" faces the gearbox, so the edge of the anti-winding protection overlaps the edge of the bevel gearbox.
• Block the shaft with the pin (29).
• Screw on the line head by hand. Caution: lefthanded thread.
• Fit the protective bar (18) with assembled line trimmer from underneath onto the guard. Bend the protective bar slightly in the process.
Important: When using the line head, never start the brushcutter without the protective bar and the line trimmer assembled.
If the length of the line has been adjusted (see chapter 8.4, "Adjusting the cutting line"), the line trimmer will automatically cut the ends of the line to the correct length during operation.
When using metal cutting blades, always work without the protective bar fitted.
C) Assembly of the "Jet-Fit " cutting head
Fig. 8a opposite side.
Insert the cutting line into the main body of the cutting head in accordance with the arrows on the main body. Insert enough line so that approx. 20 mm of the cutting line protrudes from the opening on the
ENGLISH 12
Fig. 8b Make sure that the cutting teeth are correctly aligned in the direction of rotation.
Fig. 8c
Various washers are supplied with the cutting head.
For installation on this type of brushcutter, use exactly the washer dimensions shown in the illustration (outer diameter, inner diameter).
The lower washer with an inner diameter of 16 mm must be positioned around the splines on the shaft.
Block the shaft with the pin (29) and tighten the nut
(28). Check that the cutting head is securely seated and properly centred.
Fig. 8d
Fit the cover of the cutting head in place, turn it in the direction of the arrow and tighten it with the combination wrench as shown in the illustration until it engages.
When using the "Jet-Fit-Flexiblade" cutting head, always use the standard guard and the assembled protective bar.
Cutting lines must not touch the guard and the line trimmer during rotation. If necessary, insert the cutting lines slightly further into the main body of the cutting head. The line trimmer which is assembled in the protective bar is not suitable for cutting lines. Î
The length of the cutting lines needs to be manually adjusted to the correct length.
Fig. 8e
To replace a cutting line, pull the protruding end back out from the main body in the direction of the arrow (use universal pliers if necessary).
5.4 Shoulder strap adjustment
Before commencing work, adjust the shoulder strap and handle according to the operator’s body size.
Balance the brushcutter and attached cutting blade so that the cutting tool hovers just above the ground when your hands are off the attached brushcutter.
A) Models with a "loop" handle (109L and 111L)
Wear the single shoulder strap over the opposite shoulder to the side on which you are carrying the brushcutter. Once the length of the strap has been correctly adjusted the strap hook should be over your hip. Hook the strap hook into the strap attachment on the brushcutter.
If the cutting tool hovers more than 30 cm above the ground, secure the shoulder strap retainer nearer to the engine.
If the cutter lies on the ground, secure the shoulder strap retainer nearer the handle.
B) Models with a "bike" handle (109B and 111B)
– double shoulder strap
Fig. 9
(schematic diagram)
If the cutting tool hovers more than 30 cm above the ground, secure the strap hook one hole nearer to the engine.
If the tool lies on the ground, select one hole further from the engine.
Preparing the equipment for use; Fuelling
6. Fuelling
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
Normal or super unleaded petrol can be used for individual mixing purposes (minimum octane
number 92 RON).
When using a particularly high quality proprietary
2-stroke engine oil such as the “SOLO Profi 2T-
Motoröl” which we supply, we recommend an oil:petrol mixing ratio of 1:50 (2%).
When using other brands of 2-stroke oil we recommend a mixing ratio of 1:25 (4%).
Only use proprietary 2-stroke engine oil!
Never store fuel mixture longer than 3 - 4 weeks.

• Grip the handle; the safety locking key (3) is activated via the grip area, which also enables
throttle lever (2) to be regulated.
• Press throttle lever fully down.
• Whilst holding the throttle lever down, move
stop switch (1) towards "Start"
( )
, and release the throttle lever.
The part throttle stop is cancelled by brief operation of the throttle control. The stop switch on the bike handle then jumps to the central position
Î operating position.
ENGLISH 14
Fig. 12
Adjust choke as follows:
• With a cold engine, position choke lever (7) up towards "Close" .
• With a warm engine, position choke lever (7) down.
When first starting or if the fuel tank has been completely drained and has been refilled, press
primer (8) several times (at least 5x) until the fuel is visible in the plastic bulb.
7.3 Starting
Observe the safety instructions when starting.
Fig. 13
(schematic diagram)
Lay the brushcutter level and without obstructions on the ground.
During starting, never stand or kneel on the shaft tube, otherwise the shaft or the tube might be damaged.
Take up a safe position, securely hold the machine and ensure that the cutter does not touch any objects or the ground.
When the engine is cold:
With the choke lever up ( ) start the engine by pulling the starter handle up in a straight line several times until the engine is briefly audible
(ignition).
Then immediately move the choke lever down.
Continue to start until the engine runs evenly.
When the engine is warm:
With the choke lever down start the engine by pulling the starter handle up in a straight line several times until the engine runs evenly.
If the engine is running in part throttle operation:, briefly pull the throttle back to release the half throttle detent. Release the throttle lever again to allow the engine to run at idle speed. Now you can commence working.
The following instructions are aimed at increasing the service life of the starter rope and of the starter mechanism:
• Always pull the rope out in a straight line.
• Do not let the rope drag across the edge of the rope eyelet.
• Do not pull rope all the way out - risk of the rope breaking.
• Always manually guide the rope back into its start position with your hand on the starter grip - do not let it retract on its own.
A specialist can replace a damaged starter rope.
Starting / Stopping the engine
Note: Under good conditions, the engine will already start under idling throttle if it is at operating temperature. (If a part throttle stop is set it will be cancelled by operation of the throttle control even if the engine is at standstill.)
Starting with the stop switch in run-position
If the engine will not start under idling throttle, set a part throttle stop in the way described above.
7.4 Turning off the engine:
Release the throttle and push the stop switch to
”STOP”.
Important: Due to the centrifugal clutch, the cutter will run on for a short time, even if you release the throttle. Ensure the cutter has come to a full standstill before storing the machine.
If the engine fails to start after several attempts, check whether all adjustments described above have been correctly carried out, particularly that the stop switch is not in the "STOP" position. Try starting once again. The combustion chamber will be flooded, if the engine still fails to start.
In that case we recommend you proceed as follows:
Stop switch on "STOP"
• Remove the spark plug cover.
• Pull the spark plug cap off the spark plug.
• Remove the spark plug and dry fuel mixture from the electrodes.
• Move the throttle lever up to full throttle. Pull the starter handle several times (with removed spark plug) to clear the combustion chamber.
• Move the throttle lever down to idling position, refit the spark plug, the plug cap and the plug cover.
• Then:
- Position choke lever down ("warm start")
- Slide stop switch into operating position
- Lock the throttle lever at half throttle
- Turn on engine.
Using your brushcutter
8. Using your brushcutter
8.1 Scope of Application
Only use brushcutters equipped with a nylon head
(subject to model) for cutting grass – particularly suitable around obstacles - and for trimming light weeds and wild growth near ground level. The nylon head is particularly suitable for a soft cut, e.g. for clean trimming around trees and posts.
Use brushcutters equipped with the grass cutter blade (subject to model) only for cutting grass away from obstacles and for cutting stronger weeds and wild growth near ground level.
Only use brushcutters fitted with the 3-tooth brush cutting blade (subject to model) for mowing grass, light brush, reeds and uncultivated growth at ground level.
Never use the brushcutter for any other purpose.
8.2 Initial use/ start-up behaviour
When switching on the engine for the first five times prior to commencing work, first operate for a short time in the mid-speed range without any load until the engine has warmed up a little.
8.3 Correct brushcutter operation
Observe the relevant safety instructions when using the brushcutter.
Approach the working area with the brushcutter set to idle, and then switch to full throttle. Never leave the engine running at high speed without applying a load.
Fig. 14
(Diagram: 3-tooth brush cutting blade)
Dip the tool from the r.h. side 2/3 into the material to be trimmed. Then work the brushcutter like a scythe, i.e. by moving forward step by step, whilst cutting from right to left.
Operate the brushcutter at full throttle to obtain an optimum cutting result. Never operate with the clutch in slipping range. Consequential damage through excess loads or overheating is excluded from our warranty.
Fig. 15
Due to the rotational direction of the cutting tool, using the l.h. side (section A) of the cutting tool
(from the user's perspective) provides particularly low recoil levels, especially when cutting tough growth (such as medium-sized weeds and scrub).
It is therefore best to approach the growth from the right, so the l.h. side of the cutting tool comes into contact with the growth first. Never "jab" the front of the cutting tool "into the growth".
Immediately stop the engine in case of noticeable vibrations or when material has gathered around the cutting tool or contact shield. Slow down the cutting tool by pressing it onto the ground, until it has come to a complete standstill. Pull the spark plug cap from the plug, and clean the tool seat of all grass, roots etc. Check the entire brushcutter for perfect condition.
ENGLISH 16
8.4 Note on using the nylon line head
(available as accessory)
Using your brushcutter; Operating and maintenance instructions
9. Operating and maintenance instructions
When using the nylon head, always ensure that you operate only with the correct length of line.
When the contact shield is fitted, the line will always be trimmed to the permissible length automatically (a line trimming blade is fitted into the shield). There is a high risk of injury, and the engine is subjected to excessive loads leading to a risk of damage, if nylon lines are left too long.
Important: When using the line head, never start the brushcutter without the protective bar and the line trimmer assembled.
Adjusting the cutting line
When using a semi-automatic nylon head:
Fig. 16
(schematic diagram)
Whilst the brushcutter is running without load, but with rotating nylon head, lightly push the nylon head several times onto ground with growth cover.
The cutting line will be dispensed in stages. With each action, approx. 30 mm line will be dispensed.
The line trimming blade will correct any excess length.
When the cutting line is fully spent, you can replace it with line available
Ø 2.4 mm under part no. 6900942 or
Ø 3.0 mm part no. 6900974 (accessory).
9.1 General operating and maintenance instructions
The maintenance and the repair of modern machines as well as their safety-relevant assemblies require qualified specialised training and a workshop equipped with special tools and test equipment. Consequently the manufacturer recommends that all tasks not described in these operating instructions be carried out by a specialised workshop. That specialist has the required training, experience, and equipment at his disposal, to provide you with the most costeffective solution for such work. He will provide additional help in word and deed.
After a running-in time of app. 5 hours, all accessible screws and nuts (except the carburettor adjusting screws) must be checked for tightness and they must be retightened, if required.
Check the cutter regularly and whenever you notice any irregularities, or when the cutter/contact shield becomes blocked. For this, switch off the engine and wait until the cutter has come to a complete standstill. Pull the spark plug cap, and remove grass, debris, etc. from the cutter support.
Immediately replace blunt or damaged tools, even if they display only small cracks – do a ”ping” test.
It is best to store the equipment in a dry, safe location with a full fuel tank. There should be no open flame or similar nearby. When not using the equipment for longer periods, (longer than four weeks), see chapter “9.9 Shutdown and storage”.
9.2 Information about the silencer
Your engine appliance has reduced exhaust emissions which are considerably lower than the statutory limits. The silencer creates a great deal of heat during operation as a result. Do not touch the silencer whilst it is still hot. Discolouration of the outer silencer housing is quite normal.
Operating and maintenance instructions
9.3 Sharpening instructions – metal cutting blades (subject to model)
Fig. 17
(Diagram: 3-tooth brush cutting blade)
When the blades become slightly blunt, sharpen the edges of the cutting tips with a flat file at a 30° angle.
For the 3-tooth brush cutting blade, file the edges from both sides; for the 4-tooth grass
cutting blade, file only from one side.
All cutting edges need to be filed back equally, if the wear and tear is substantial, or if there are broken-off cutting edges. It is necessary to check for imbalance and if necessary, to make corrections by additional filing. The sharpening angle is 30°.
For the 3-tooth brush cutting blade, your dealer offers a sharpening jig (part no.: 0080548) to help with sharpening.
To lubricate the bevel gear drive, use SOLO
"Special gearbox grease" (part no. 008318025).
Check the grease level weekly and top up, if required (approx. every 20 - 50 hours).
Fig. 18
Remove the filler plug from the side of the gearbox.
If no grease is visible inside, top up with grease
(top-up quantity approx. 5 – 10 g).
Replace and tighten the filler plug.
Please note: Do not overfill with grease, as that may lead to the gearbox overheating. Never fill the gearbox casing to the top with grease.
Tip: If required, top up with a maximum of 5g grease. It is preferable to check more frequently
(e.g. before you start working) whether grease is still visible.
Your SOLO dealer workshop is happy to help you in case of doubt.
ENGLISH 18
The carburettor is adjusted at the factory for optimum performance. Subject to the place of use
(mountains, low-lying areas), the average idling speed given in the specification can be adjusted as follows, via the idling end-stop screw "T" (the use of a rev counter is recommended):
Fig. 19
• 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.
With the throttle set to idle, the cutting tool must not, under any circumstances, rotate!
If the idling speed cannot be set correctly with the idling end-stop screw "T", request an authorised service centre to tune the carburettor.
The adjusting screws for the idling mixture "L" and the full-load mixture "H" must only be adjusted by an authorised workshop.
The following instructions are for authorised service shops
Use the D-CUT carburettor key to adjust the idle mixture screw "L" and the full load mixture screw
"H".
Ask the specialist workshop that is part of our customer service about standard settings, or visit our internet portal for dealers at www.part-andmore.org.
Clean the air filter before adjusting the low speed screw!
Let the engine run warm before adjusting the engine speed.
The carburettor is tuned for optimum engine performance. Use a rev counter to tune the carburettor correctly!
Do not adjust the engine to a higher speed.
Operating and maintenance instructions
Excessive engine speed can lead to major engine damage!
9.6 Information about the spark plug
Check the spark plug regularly after 50 hours of operation.
Fig. 20
Removing the spark plug:
• Press the top tab of the spark plug cover (16) down
(a), push back (b) and remove.
• Remove the spark plug cap below this.
• Remove spark plug using the combination spanner and dry thoroughly.
When the spark plug has been removed or the ignition cable has been pulled out of the plug cap, the engine must not be moved. There is a risk of fire through sparks.
Checking the spark plug:
• Clean spark plug with a dry cloth and check electrodes. There must not be any dirt between the electrodes. Brush dirt out with a thin paintbrush if necessary.
• If the electrodes have been heavily worn away, replace the spark plug immediately – otherwise after 100 hours run.
• The correct electrode gap is 0.5 mm. If the electrodes are bent and the electrode gap is incorrect, replace the spark plug.
• Before starting work, check ignition cable for perfect connection and insulation.
The permissible spark plug (interference-free, energy value 240) is available under the following description:
BOSCH USR 4 AC
Fitting the spark plug:
• Refit the spark plug and tighten using the combination spanner (recommended torque if using a torque spanner Î 10 Nm).
• Always push the spark plug cap firmly onto the spark plug.
• Position spark plug cover (16) on casing and push on until it clicks back into place.
Operating and maintenance instructions
9.7 Air Filter Maintenance
Contaminated air filters cause a reduction in engine performance and increase fuel consumption with more pollutants in the exhaust gas. Engines are less likely to start readily with a contaminated air filter.
As a basic principle therefore, the air filter should be cleaned as follows before starting work, and intermittently in very dusty conditions:
Fig. 21
Before opening the air filter, close the choke to prevent dirt entering the carburettor.
• Push tab (a) in, only slightly open air filter lid
(11) and remove by rotating gently back and forth
• Remove foam filter (c) from the lid and clean the area around the filter.
• Thoroughly clean air filter casing (d) and air filter cover (11) on the inside, using a paintbrush or by carefully blowing on them.
• Clean filter insert (c) by shaking it out or carefully blowing on it.
If the filter insert is damaged or so contaminated that it is impossible to clean, replace it with the original spare part (part no. 20 48 406).
• Insert the new or cleaned foam filter into the air filter lid.
• Position the air filter cover with both tabs (b)
[inside, opposite tab (a)] in the corresponding two pockets (b’) of the filter casing.
• Press air filter cover against the filter casing until tab (a) clicks audibly into place.
9.8 Replacing the fuel filter
We recommend having the fuel filter (34) changed annually by a specialised service centre.
Fig. 22
(schematic diagram)
A trained mechanic can carefully remove the fuel filter via a wire loop through the fuel tank filler.
Ensure that the thicker part of the fuel hose on the tank wall is not drawn into the fuel tank.
9.9 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.
• Clean leftover cuttings off the blades using a small brush.
• Ingrained plant remains on the blades can be removed with the " SOLO Universal Cleaner "
(part no.: 00 83 116). Leave it to work for a short time, then residues become soft and partially dissolve, and can be wiped off with a cloth.
• To prevent corrosion, we recommend treating metal cutting tools with the " SOLO Maintenance and Care Oil " (part no.: 00 83 163).
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.
