Safety Precautions and
Working Techniques
Because a trimmer / brushcutter is a highspeed, fast-cutting power tool sometimes equipped with sharp cutting blades, special safety precau- tions must be observed to reduce the risk of per- sonal injury.
It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manual and the safety precautions periodically. Careless or improper use may cause serious or fatal injury.
The terminology utilized in this manual when referring to the power tool reflects the fact that different types of cutting attachments may be mounted on it. The term "trimmer" is used to designate an FS unit thatisequippedwith anylonline head or a head with flexible plastic blades (i.e., the PolyCut head.) A "brushcutter" designates a unit equipped with a rigid metal blade. Many FS models may be used as either a trimmer or a brushcutter – therefore, the powertoolisreferredinthismanualasa "trimmer / brushcutter". Some smaller and / or lightweight FS models may only be used as a trimmer, i.e., they may not be used with metal blades.
FSmodelswithan"R"onthenameplate were originally configured (at the time of distribution) as a trimmer with a loop handle.
Warning!
As more fully explained later in these SafetyPrecautions,toreducetheriskof personal injury, make sure your unit is equipped with the proper handle, har- nessanddeflectorforthetypeofcutting attachment you are using. Use only cut- ting attachments that are specifically authorized by STIHL for use on your FS model.
Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances.
Warning!
Do not lend or rent your power tool with- out the instruction manual. Be sure that anyone using it understands the infor- mation contained in this manual.
Warning!
The use of this machine may be hazard- ous.Iftherotatinglineorbladecomesin contact with your body, it will cut you.
When it comes in contact with solid for- eign objects such as rocks or bits of metal, it may fling them directly or by ric- ochet in the direction of bystanders or theoperator.Strikingsuchobjectscould damagethecuttingattachmentandmay cause blades to crack, chip or break. Thrownobjects,includingbrokenheads or blades, may result in serious or fatal injury to the operator or bystanders.
English
STIHL does not recommend the use of rigid blades when cutting in stony areas.
Useyourtrimmer/brushcutterequipped with the appropriate cutting attachment only for cutting grass and similar material.
Warning!
Do not use it for other purposes, since misuse may result in personal injury or property damage, including damage to the machine.
Warning!
Minors should never be allowed to use this power tool. Bystanders, especially children, and animals should not be allowed in the area where it is in use.
Warning!
To reduce the risk of injury to bystand- ers and damage to property, never let yourpowertoolrununattended.Whenit is not in use (e.g. during a work break), shut it off and make sure that unauthor- ized persons do not use it.
Most of these safety precautions and warnings apply to the use of all STIHL trimmer / brushcutters. Different models may have different parts and controls. See the appropriate section of your instruction manual for a description of thecontrols and thefunctionofthe parts of your model.

Safe use of a trimmer / brushcutter involves
1.the operator
2.the power tool
3.the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this machine when you are fatigued.
Warning!
Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating this machine.
Warning!
Prolonged use of a power tool (or other machines) exposing the operator to vibrations may produce whitefinger dis- ease (Raynaud's phenomenon) or carpal tunnel syndrome.
These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.
All factors which contribute to whitefinger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of exposure to vibration are mentioned as factorsinthedevelopmentofwhitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:
–Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the machine to the operator's hands. An AV system is recommended for those persons using power tools on a regular or sustained basis.
–Wear gloves and keep your hands warm.
–Keep the AV system well maintained. A power tool with loose components or with damaged or worn AV elements will tend to have higher vibration levels.
–Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressure. Take frequent breaks.
All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.
Warning!
The ignition system of the STIHL unit produces an electromagnetic field of a very low intensity. This field may inter- fere with some pacemakers. To reduce theriskofseriousorfatalinjury,persons with a pacemaker should consult their physician and the pacemaker manufac- turer before operating this tool.
Proper Clothing
Warning!
Toreducetheriskofinjury,theoperator should wear proper protective apparel.
The deflector provided with your power tool will not protect the operator from all foreign objects (gravel, glass, wire, etc.) thrown back by the rotating cutting attachment. Thrown objects may also ricochet and strike the operator.

FS 56, FS 56 R, FS 56 C, FS 56 RC |
Warning!
To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles
or properly fitted protec- tive glasses with
adequate top and side protection com- plying with ANSI Z 87.1 (or your applicable national standard). To reduce the risk of injury to your face STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.
Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.
Power tool noise may damage your hearing.Wearsoundbarriers(earplugs or ear mufflers) to protect your hearing. Continual and regular users should have their hearing checked regularly.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
Always wear gloves when handling the machine and metal blades. Heavy-duty, non- slip gloves improve your grip and help to protect your hands.
Clothing must be sturdy and snug-fitting, but allow
complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts, sandals or go barefoot.
Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become caught on branches, brush or the moving parts of the unit. Secure hair so it is above shoulder level.
Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended.
THE POWER TOOL
For illustrations and definitions of the power tool parts see the chapter on "Main Parts."
English
Warning!
Nevermodifythispowertoolinanyway. Only attachments supplied by STIHL and expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthor- ized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous. For the cutting attachments authorized by STIHL for your unit, see the chapter "Approved Combinations of Cutting Attachment, Deflector, Handle and Har- ness" in the instruction manual or the STIHL "Cutting Attachments, Parts & Accessories" catalog.
If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work.Checkin particularthat the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. Incaseofdoubt,haveitcheckedbyyour STIHL servicing dealer.
THE USE OF THE POWER TOOL
Transporting the Power Tool
Warning!
To reduce the risk of injury from loss of control and blade or line contact, never carry or transport your power tool with the cutting attachment moving.

Warning!
Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and seri-
ous burn injury or property damage. Use extreme caution when handling gasoline or fuel mix. Do notsmokeorbringanyfireorflamenear the fuel or the power tool. Note that combustible fuel vapor may escape from the fuel system.
Fueling Instructions
Warning!
To reduce the risk of serious injury from burns, never attempt to refuel the unit until it has been completely removed from the operator.
Warning!
Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refu- eling. Gasoline vapor pressure may build up inside the fuel tank depending onthefuelused,theweatherconditions and the tank venting system.
In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler caponyourpowertoolcarefullysoasto allow any pressure build-up in the tank to releaseslowly.Neverremove thefuel filler cap while the engine is running.
Selectbaregroundforfueling andmove at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine.
Warning!
Check for fuel leakage while refueling and dur- ing operation. If fuel leakage is found, do not start or run the engine untiltheleakisfixedand
any spilled fuel has been wiped away. Take care not to get fuel on your cloth- ing. If this happens, change your clothing immediately.
Different models may be equipped with different fuel caps.
Toolless cap with grip
Warning!
In order to reduce the risk of fuel spill- age and fire from an improperly tightened fuel cap, correctly position and tighten the fuel cap in the fuel tank opening.

During Operation
Holding and Controlling the Power Tool
002BA273 KN
Always hold the unit firmly with both hands on the handles while you are working. Wrap your fingers and thumbs around the handles.
Warning!
To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support. Never hold the cutting attachment above waist height.
Warning!
Neverattempttooperate your power tool with one hand. Loss of control of
the power tool resulting in serious or fatal injury may result. To reduce
the risk of cut injuries, keep hands and feet away from the cutting attachment. Never touch a moving cutting attach- ment withyourhand orany otherpartof your body.
Warning!
Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (wet ground, snow) and in difficult, over- grown terrain. Watch for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. For bet- ter footing, clear away scrub and cuttings. Be extremely cautious when working on slopes or uneven ground.
Working Conditions
Operate and start your power tool only outdoors in a well ventilated area. Operate it under good visibility and daylight conditions only. Work carefully.
Warning!
As soon as the engine is running, this product generates toxic exhaust
fumes containing chemi- cals, such as unburned hydrocarbons (including
benzene) and carbon monoxide, that are known to cause respiratory prob- lems, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be color- less and odorless. To reduce the risk of serious or fatal injury / illness from inhal- ing toxic fumes, never run the machine indoors or in poorly ventilated locations.
Warning!
If the vegetation being cut or the sur- rounding ground is coated with a chemical substance (such as an active pesticide or herbicide), read and follow the instructions and warnings that accompanied the substance at issue.
Warning!
Inhalation of certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction. Sub- stantial or repeated inhalation of dust andotherairborne contaminants,inpar- ticular thosewith asmaller particlesize, may cause respiratory or other ill- nesses. Control dust at the source where possible. Use good work prac- tices, such as operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recom- mendations of EPA / OSHA / NIOSH and occupational and trade associa- tions with respect to dust ("particulate matter".) When the inhalation of dust cannot be substantially controlled, i.e., kept at or near the ambient (back- ground) level, the operator and any bystanders should wear a respirator approvedbyNIOSH/MSHAforthetype of dust encountered.
Operating Instructions
Warning!
Do not operate your power tool using the starting throttle lock, as you do not have control of the engine speed.

In the event of an emergency, switch off the engineimmediately– movetheslide control / momentary stop switch to 0 or STOP.
Warning!
The cutting attachment continues to rotate for a short period after the throttle trigger is released (flywheel effect.)
Warning!
The rotating cutting attachment may fling foreign objects directly or by rico- chet a great distance.
15m (50ft)
Toreducetheriskofeyeandotherinjury always wear proper eye protection (see the chapter on "Proper Clothing") and ensure that bystanders are at least 50 feet (15 m) away. To reduce the risk ofdamagetoproperty,alsomaintainthis distance from such objects as vehicles orwindows.Anycoworkerswhomustbe in the restricted area should also wear goggles or protective glasses. Stop the engine immediately if you are approached.
Warning!
Before you start work, examine the area for stones,glass,fencewire, metal,trashorothersolid
objects. The cutting attachment could throw
objects of this kind.
Warning!
This trimmer / brushcutter is normally to be used at ground level with the cutting attachment parallel to the ground. Use of a trimmer / brushcutter above ground level or with the cutting attachment per- pendicular to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the power tool may be more difficult to control.
Warning!
During cutting, check the tightness and the condition of the cutting attachment atregularshortintervalswiththeengine andattachmentstopped.Ifthebehavior of the attachment changes during use, stop the engine immediately, wait until thecuttingattachmentstops,andcheck the nut securing the attachment for tightness and the blade or head for cracks, wear and damage.
English
Warning!
A loose blade or head may vibrate, crack, break or come off the trimmer / brushcutter,whichmayresultinserious orfatalinjury.Makesurethatthecutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the blade or head loosens after being prop- erly tightened, stop work immediately. The retaining nut may be worn or dam- aged and should be replaced. If the blade or head continues to loosen, see yourSTIHLdealer.Neveruseatrimmer / brushcutter with a loose cutting attachment.
Warning!
Replace a cracked, damaged or wornout head or a cracked, bent, warped, damaged, dull or worn out blade imme- diately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.
Warning!
When using rigid blades, avoid cutting close to fences, sides of buildings, tree trunks,stonesorothersuchobjectsthat couldcausethepowertooltokickoutor could cause damage to the blade.
STIHL recommends use of the nylon line heads for such jobs. In addition, be alert to an increased possibility of rico- chets in such situations.

Warning!
Never modify your muffler. Any modifi- cation could cause an increase in heat radiation,sparksorsoundlevel,thereby increasing the risk of fire, burn injury or hearingloss.Youmayalsopermanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only.
Warning!
The muffler and other parts of the engine (e.g. fins of the cylinder, spark plug) become hot during operation and remain hot for a while after stopping the engine. To reduce risk of burns, do not touch the muffler and other parts while they are hot. Keep the area around the muffler clean. Remove excess lubricant and all debris such as pine needles, branches or leaves. Let the engine cool down sitting on concrete, metal, bare ground or solid wood (away from any combustible substances.
Warning!
Animproperlymountedordamaged cyl- inder housing or a damaged/deformed muffler shell may interfere with the cool- ingprocessofthemuffler.Toreducethe riskoffireorburninjury,donotcontinue work with a damaged or improperly mounted cylinder housing or a dam- aged/deformed muffler shell.
Your muffler is furnished with a spark arresting screen designed to reduce the risk of fire from the emission of hot particles. Never operate your unit with a missing or damaged spark arresting screen.Ifyourgas/oilmixratioiscorrect
(i.e., not too rich), this screen will normally stay clean as a result of the heat from the muffler and need no service or maintenance. If you experiencelossofperformanceandyou suspect a clogged screen, have your mufflermaintained byaSTIHL servicing dealer. Some state or federal laws or regulations may require a properly maintained spark arrestor for certain uses.Seethe"Maintenance,Repairand Storing" section of these Safety Precautions. Remember that the risk of a brush or forest fire is greater in hot or dry conditions.
Warning!
Some STIHL power tools are equipped with a cata- lytic converter, which is
designed to reduce the exhaust emissions of the engine by a chemical
process in the muffler. Due to this proc- ess, the muffler does not cool down as rapidly as conventional mufflers when the engine returns to idle or is shut off. To reduce the risk of fire and burn inju- ries when using a catalytic converter, always set your power tool down in the upright position and never locate it where the muffler is near dry brush, grass, wood chips or other combustible materials while it is still hot.
USING THE CUTTING ATTACHMENT
For an illustration of the various cutting attachments and instructions on proper mounting see the chapter on "Mounting the Cutting Attachment" in your instruction manual.
FS 56, FS 56 R, FS 56 C, FS 56 RC
Warning!
To reduce the risk of severe or fatal injuryfromblade contactand /orlossof control, never attempt to use a metal blade on an FS model for which it is not authorized.
Using the Mowing Heads
Do not use with mowing line longer than the intended length. With a properly mounted deflector, the built-in linelimiting blade will automatically adjust the line to its proper length.
Using the unit with an overly long nylon cutting line increases the load on the engineandreducesitsoperatingspeed. This causes the clutch to slip continuously and results in overheating and damage to important components (e.g. clutch, polymer housing components.) Such damage could, among other things, cause the cutting attachment to rotate at idle.
002BA354 KN
Mowing heads are to be used only on trimmer / brushcutters equipped with a line-limiting blade in the deflector in order to keep the line at the proper length (see "Main Parts" chapter in your instruction manual.)
If the lawn edges are planted with trees or bordered by a fence etc., it is best to use a nylon line head. It achieves a "softer" cut with less risk of damaging tree bark etc. than polymer blades.
However, the polymer-bladed STIHL PolyCut produces a better cut if there arenoplantsalongtheedgeofthelawn. Sharpening is not necessary, and worn polymer blades are easily replaced.
Warning!
To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.
STIHL SuperCut mowing head
Fresh line is advanced automatically. Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head.)
STIHL AutoCut mowing head
Nylon cutting line advances automatically when tapped against the ground (TapAction.)
STIHL TrimCut mowing head
Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head.)
English
STIHL PolyCut mowing head
002BA177 KN |
Uses either nylon lines or nonrigid, pivoting polymer blades.
Observe wear indicators.
Warning!
Three rectangular wear limit marks are applied to the base (periphery) of the PolyCut. To reduce the risk of serious injury from breakage of the head or blades, the PolyCut must not be used when it has worn as far as one of these marks. It is important to follow the main- tenance instructions supplied with the head.
Warning!
Ifthewearlimitmarksareignored,there is a risk of the cutting attachment shat- tering and flying parts injuring the operator or bystanders. To reduce the risk of accidents from shattered blades, avoid contact with stones, metal and similar solid objects. Check PolyCut blades for cracks at regular intervals. If a crack is found on one blade, always replace all blades.
STIHL FixCut mowing head Uses pre-cut lengths of nylon line. Observe wear indicators.

English
Do not continue using the mowing head if the raised moldings (1) on the base are missing or worn – see right illustration above. The mowing head mayotherwiseshatterandflyingobjects could result in injury to the operator or bystanders. Install a new mowing head.
Risk of Kickout (Blade Thrust) with All Rigid Cutting Blades
002BA135 KN
Warning!
Kickout(bladethrust)isthesuddenand uncontrolled motion towards the opera- tor's right or rear that can occur when the shaded area (especially the darkly shaded area) of a rotating blade comes in contact with a solid rigid object like a tree, rock, bush or wall. The rapid coun- terclockwise rotation of the blade may be stopped or slowed, and the cutting attachmentmaybethrowntotherightor to the rear.
This kickout (blade thrust) may cause lossofcontrolofthepowertoolandmay result in serious or fatal injury to the operator or bystanders. To reduce the risk of injury, extreme caution should be used when cutting with the shaded area of any rigid blade.
Using the Grass Cutting Blade
002BA355 KN
All kinds of grass and weeds can be easily cut with the grass cutting blade. The power tool is swept in an arc similar to a scythe.
Warning!
To reduce the risk of serious or fatal injury from blade breakage, never attempt to use this blade to cut woody materials.
The 4-tooth grass cutting blade is intended to cut grass and weeds. It has 4 cutting knives with cutting edges on both sides, i.e. front and rear. When the cutting edges on one side become dull, the blade can be turned over to utilize the cutting edges on the other side.
The 8-tooth grass cutting blade is recommended for cutting fern or reed.
Bothtypesofgrasscuttingbladehaveto be resharpened when all cutting edges are dull.
MAINTENANCE, REPAIR AND STORING
Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage.
Warning!
Use only identical STIHL replacement partsformaintenanceandrepair.Useof non-STIHL parts may cause serious or fatal injury.
Strictly follow the maintenance and repair instructions in the appropriate sections of your instruction manual.
Warning!
Always stop the engine and make sure that the cutting attachment is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attemptanymaintenanceorrepairwork not described in your instruction man- ual. Have such work performed by your STIHL servicing dealer only.
Wear gloves when handling or performing maintenance on blades.

FS 56, FS 56 R, FS 56 C, FS 56 RC |
Warning!
Use the specified spark plug, and make sure it and the ignition lead are always clean and in good condition. Always press the spark plug boot snugly onto the spark plug terminal of the proper size. (Note: If the terminal has a detach- able SAE adapter nut, it must be securely attached.) A loose connection between the spark plug and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.
Warning!
Never test the ignition system with the sparkplugbootremovedfromthespark plugorwitharemovedsparkplug,since uncontained sparking may cause a fire.
Warning!
Do not operate your power tool if the muffler is damaged, missing or modi- fied. An improperly maintained muffler will increase the risk of fire and hearing loss. Your muffler is equipped with a spark-arresting screen to reduce the risk of fire; never operate your power toolifthescreenismissing,damagedor clogged. Remember that the risk of a brushorforestfireisgreaterinhotordry weather.
In California, it is a violation of § 4442 or § 4443 or the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a complying spark arrester that is maintained in effective working order.
FS 56, FS 56 R, FS 56 C, FS 56 RC
English
The owner/operator of this product is responsible for properly maintaining the spark arrester. Other states or governmentalentities/agencies,suchas the U.S. Forest Service, may have similar requirements. Contact your local fire agency or forest service for the laws or regulations relating to fire protection requirements.
Warning!
Never repair damaged cutting attach- ments by welding, straightening or modifying the shape. This may cause parts of the cutting attachment to come off and result in serious or fatal injuries.
Keep blades sharp. Tighten all nuts, bolts and screws, except the carburetor adjustment screws, after each use.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.
Store the power tool in a dry and high or locked location out of reach of children.
Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the Machine" in the instruction manual.

Fuel
This engine is certified to operate on unleaded gasoline and the STIHL twostroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of highquality gasoline and two-stroke air cooled engine oil.
Usemid-gradeunleadedgasolinewitha minimum octane rating of 89 (R+M/2) and no more than 10% ethanol content.
Fuel with a lower octane rating may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine.
The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines,etc.),butmagnesiumcastingsand catalytic converters as well. This could cause running problems or even damage the engine. For this reason STIHL recommends that you use only high-quality unleaded gasoline!
Gasoline with an ethanol content of more than 10% can cause running problems and major damage in engines with a manually adjustable carburetor and should not be used in such engines.
The ethanol content in gasoline affects engine running speed – it may be necessary to readjust the carburetor if you use fuels with various ethanol contents.
Warning!
To reduce the risk of personal injury from loss of control and / or contact with the running cutting tool, do not use your unit with incorrect idle adjustment. At correct idle speed, the cutting tool should not move.
If your power tool shows an incorrect idleadjustment,haveyourSTIHLdealer check your power tool and make proper adjustments and repairs.
The idle speed and maximum speed of the engine change if you switch from a fuel with a certain ethanol content to another fuel with a much higher or lower ethanol content.
This problem can be avoided by always using fuel with the same ethanol content.
Use only STIHL two-stroke engine oil or equivalent high-quality two-stroke engine oils that are designed for use only in air cooled two-cycle engines.
WerecommendSTIHLHPUltra2-Cycle Engine Oil since it is specially formulated for use in STIHL engines.
Do not use BIA or TCW rated (twostroke water cooled) mix oils or other mixoilsthatstatetheyareforuseinboth water cooled and air cooled engines (e.g., outboard motors, snowmobiles, chain saws, mopeds, etc.).
Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapor. When filling at the pump, first remove the container from your vehicle and place the containeronthegroundbeforefilling.To reduce the risk of sparks from static

discharge and resulting fire and/or explosion, do not fill fuel containers that are sitting in or on a vehicle or trailer.
The container should be kept tightly closed in order to limit the amount of moisture that gets into the mixture.
The machine‘s fuel tank should be cleaned as necessary.
Fuel mix ages
Only mix sufficient fuel for a few days work,nottoexceed3monthsofstorage. Store in approved fuel-containers only. When mixing, pour oil into the container first, and then add gasoline. Close the container and shake it vigorously by hand to ensure proper mixing of the oil with the fuel.
