Safety Precautions and

Working Techniques

Because a pole pruner is a high-speed, fast-cut- ting power tool with a

very long reach, special safety precautions must be observed to reduce the risk of personal 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.

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 without the instruction manual. Be sure that anyone using it understands the information contained in this manual.

WARNING

The use of this machine may be hazardous. The pole pruner chain has manysharpcutters.Ifthecutterscontact your flesh, they will cut you, even if the chain is not moving.

Do not cut any material other than wood orwoodenobjects.Useyourpolepruner for limbing only.

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

Toreducetheriskofinjurytobystanders and damage to property, never let your power tool run unattended. When it is not in use (e. g. during a work break), shut it off and make sure that unauthorized persons do not use it.

Most of these safety precautions and warnings apply to the use of all STIHL polepruners.Differentmodelsmayhave different parts and controls. See the appropriate section of your instruction manual for a description of the controls and the function of the parts of your model.

Safe use of a pole pruner involves

1.the operator

2.the power tool

3.the use of the power tool.

English

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.Ifyouhaveanyconditionthat mightbeaggravatedbystrenuouswork, 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 disease (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

HT 100, HT 101, HT 130, HT 131

English

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 interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with a pacemaker should

consult their physician and the pacemaker manufacturer before operating this tool.

Proper Clothing

WARNING

To reduce the risk of injury, the operator should wear proper protective apparel.

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 complying with ANSI Z 87.1 "+" (or your applicable national stand- ard). 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.

Power tool noise may damage your hearing. Wear sound barriers (ear plugs 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 heavy duty work gloves (e.g. made of leather or other wear resistant material) when handling the machine and the cutting tool. Heavy-duty, nonslip 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 with cut retardant inserts are recommended.

THE POWER TOOL

For illustrations and definitions of the power tool parts see the chapter on "Main Parts".

Thispowertoolshouldbecarriedonlyin a horizontal position. Grip the shaft in a manner that the machine is balanced horizontally. Keep the hot muffler away from your body and the cutting attachment behind you. Accidental

accelerationoftheenginecancausethe chain to rotate and cause serious injuries.

WARNING

Always switch off the engine and fit the scabbard over the cutting attachment before transporting the power tool over longdistances.When transporting it ina vehicle, properly secure it to prevent turnover, fuel spillage and damage to the unit.

Fuel

Your STIHL power tool uses an oilgasoline mixture for fuel (see the chapter on "Fuel" of your instruction manual).

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 not smoke or bring any fire or flame near the fuel or the power tool. Note that combusti- ble fuel vapor may escape from the fuel system.

English

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 refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions 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 cap onyour power toolcarefullysoas to allow any pressure build-up in the tank toreleaseslowly. Never remove 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.

HT 100, HT 101, HT 130, HT 131

English

WARNING

Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately.

WARNING

Inordertoreducetheriskoffuelspillage and fire from an improperly tightened fuel cap, correctly position and tighten the fuel cap in the fuel tank opening.

Different models may be equipped with different fuel caps.

Toolless cap with grip

001BA220 KN

To do this with this STIHL cap, raise the griponthetopofthecapuntilitisupright at a 90° angle. Insert the cap in the fuel tank opening with the raised positioning marks on the grip of the cap and on the fuel tank opening lining up. Using the grip, press the cap down firmly while turning it clockwise as far as it will go (approx. 1/4 turn).

Fold the grip flush with the top of the cap. Grip the cap and check for tightness. If the grip does not lie completely flush

with the cap and the detent on the grip does not fit in the correspond- ing recess in the filler opening, or if the cap is loose in the filler opening, the cap is not properly seated and tightened and you must repeat the above steps.

Misaligned, damaged or broken cap

NIfthecapdoesnotdropfullyintothe openingwhenthepositioningmarks line up and/or if the cap does not tighten properly when twisted, the baseofthecapmaybeprematurely rotated (in relation to the top) to the closed position. Such misalignment can result from handling, cleaning or an improper attempt at tightening.

NTo return the cap to the open position for installation, turn the cap (with the grip up) until it drops fully intothetankopening.Next,twistthe capcounterclockwiseasfarasitwill go (approx. 1/4 turn) – this will twist the base of the cap into the correct position. Then, twist the cap clockwise, closing it normally.

NIf your cap still does not tighten properly, it may be damaged or broken; immediately stop use of the unit and take it to your authorized STIHL dealer for repair.

Screw Cap

WARNING

Unit vibrations can cause an improperly tightened fuel filler cap to loosen or

come off and spill quanti- ties of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible.

See also the "Fueling" chapter in your Instruction Manual for additional information.

HT 100, HT 101, HT 130, HT 131

Before Starting

Takeoffthechainguard(scabbard)and inspect the pole pruner for proper condition and operation. (See the maintenance chart near the end of the instruction manual.)

WARNING

Alwayscheckyour power toolforproper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch and cutting attachment. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices.

WARNING

Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections,manual fuelpump (onlyfor powertoolsequippedwithamanualfuel pump). Do not start the engine if there are leaks or damage – risk of fire! Have the machine repaired by a servicing dealer before using it.

WARNING

Never operate your power tool if it is damaged, improperly adjusted or maintained, or not completely or securely assembled.

WARNING

Check that the spark plug boot is securely mounted on the spark plug – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.

Keep the handles clean and dry at all times; it is particularly important to keep themfreeofmoisture,pitch,oil,fuelmix, grease or resin in order for you to maintain a firm grip and properly control your power tool.

For proper assembly of the bar and chain follow the procedure described in the chapter "Mounting the Bar and Chain" of your instruction manual.

STIHL Oilomatic chain, guide bar and sprocket must match each other in gauge and pitch.

WARNING

Proper chain tension is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hex nut(s) for the sprocket cover is (are) tightened securely after tensioning the chain. Check chain tension once more after having tightened the nut(s). Never start the pole pruner with the sprocket cover loose.

Adjustcarryingharnessandhandgripto suit your size before starting work.

Starting

To reduce the risk of fire and burn injuries, start the engine at least 10 feet (3 m) from the fueling spot, outdoors only.

Start and operate your pole pruner without assistance.

Forspecificstartinginstructions,seethe appropriate section of your manual. Proper starting methods reduce the risk of injury.

English

275BA006 KN

Place the pole pruner on firm ground or othersolid surface inanopenareaor,in the alternative, as shown in the above picture. Maintain good balance and secure footing.

WARNING

To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool.

WARNING

To reduce the risk of injury from loss of control be absolutely sure that the guide bar and chain are clear of you and all otherobstructionsandobjects,including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage the sprocket and turn the chain.

Once the engine has started, immediately blip the throttle trigger, whichshouldreleasethestartingthrottle and allow the engine to slow down to idle.

With the engine running only at idle, attach the power tool to the spring hook of your harness (see appropriate chapter of this manual).

English

WARNING

When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism.

Important Adjustments

WARNING

To reduce the risk of personal injury from loss of control or contact with the running cutting tool, do not use your unit with incorrectidleadjustment. Atcorrect idle speed, the saw chain should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual.

If you cannot set the correct idle speed, have your STIHL dealer check your power tool and make proper adjustments and repairs.

Properchaintensionisveryimportantat all times. Check it at regular intervals (whenever the pole pruner is shut off). If the chain becomes loose while cutting, switch off the engine and then tighten. Never try to tighten the chain while the engine is running.

During Operation

Holding and Controlling the Power Tool

Always hold the unit firmly with both hands on the handles while you are working. Wrap your fingers and thumbs around the handles.

WARNING

As soon as the engine is running, this product gen- erates toxic exhaust

fumes containing chemi- cals, such as unburned hydrocarbons (including benzene) and carbon monoxide, that are known to cause respira- tory problems, 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 inhaling toxic fumes, never run the machine indoors or in poorly venti- lated locations. If exhaust fumes become concen- trated due to insufficient ventilation, clear obstruc- tions from work area to permit proper ventilation before proceeding and / or take frequent breaks to allow fumes to dissipate before they become concentrated.

WARNING

Inhalation of certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction.

Substantial or repeated inhalation of dustandotherairbornecontaminants,in particular those with a smaller particle

HT 100, HT 101, HT 130, HT 131

size, may cause respiratory or other illnesses. This includes wood dust, especially from hardwoods, but also from some softwoods such as Western Red Cedar. Control dust at the source where possible. Use good work practices, such as such as always cutting with a properly sharpened chain (which produces wood chips rather than fine dust) and operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recommendations of EPA / OSHA / NIOSH and occupational and trade associations with respect to dust ("particulate matter"). When the inhalation of dust cannot be substantially controlled, i.e., kept at or neartheambient(background)level,the operator and any bystanders should wear a respirator approved by NIOSH / MSHA for the type of dust encountered.

WARNING

Breathing asbestos dust is dangerous and can cause severe or fatal injury, respiratory illness or cancer. The use and disposal of asbestos-containing products have been strictly regulated by OSHAandtheEnvironmentalProtection Agency. If you have any reason to believe that you might be cutting asbestos, immediately contact your employer or a local OSHA representative.

WARNING

This power tool has a large range. In order to reduce the risk of personal or even fatal injury to bystanders from fallingobjectsorinadvertentcontactwith

can arc. Electricity can also move through branches, especially if they are wet. Maintain a clearance of at least 50 feet (15 m) between the pole pruner (including any branches it is contacting) and any electrical line carrying live current. Before working with less clearance, contact your electric utility and make sure the current is turned off.

Operating Instructions

WARNING

Donotoperateyourpowertoolusingthe starting throttle position, as you do not have control of the engine speed.

In the event of an emergency, switch off the engineimmediately– movetheslide control / stop switch to 0 or STOP.

WARNING

To reduce the risk of cut injuries, keep hands and feet away from the saw chain. Never touch a moving chain with yourhandoranyotherpartofyourbody. The saw chain continues to move for a short period after the throttle trigger is released (inertia effect).

Accelerating the engine while the chain is blocked increases the load and will cause the clutch to slip continuously.

This may result in overheating and damage to important components (e. g. clutch, polymer housing components) – whichcanthenincreasetheriskofinjury from the chain moving while the engine is idling.

WARNING

If the chain becomes clogged, always turn off the engine and make sure the chain has stopped before cleaning.

Make sure that the saw chain does not touch any foreign materials such as rocks, fences, nails and the like. Such objects may be flung off and injure the operator or bystanders, or damage the saw chain.

WARNING

Prior to limbing, clear the working area from interfering limbs and brush. Then, establish an escape area away from wherethecutlimbscanfall,andremove all obstacles.

Keep work area clear – move away fallen limbs. Place all tools and equipment at a safe distance from the branches being limbed, but not in the escape area.

WARNING

Always observe the general condition of the tree. Look for decay and rot in the trunk and branches. If it is rotted inside, itcouldsnapandfalltowardtheoperator while being cut. Also look for broken or dead branches which could vibrate loose and fall on the operator. If branch is thick or heavy, make a shallow relief cut on the bottom of the branch before cuttingdownfromthetoptohelpprevent splitting of the branch.

WARNING

Toreducetheriskofsevereorevenfatal injury from falling objects do not cut verticallyaboveyourbody.Holdthepole pruner at an angle of not more than 60° from the horizontal level (see picture). Objects may fall in unexpected directions. Do not stand directly underneath the limb being cut!

Watch for falling wood! As soon as the limbed branch starts to fall, step aside andkeepasufficientdistanceawayfrom the falling wood.

WARNING

Always pull the unit out of the cut with the chain running to reduce the possibility of pinching the cutting attachment. Don't put pressure on the pole pruner when reaching the end of a cut. The pressure may cause the bar

androtatingchaintopopoutofthecutor kerf, go out of control and strike some other object.

If the bar becomes pinched and caught in the branch so that the chain can no longer move, shut off the pole pruner and carefully move the branch to open the pinch and release the bar.

WARNING

If a rotating saw chain strikes a rock or other hard object, sparks may be created, which can ignite flammable materials under certain circumstances. Flammable materials can include dry vegetation and brush, particularly when weather conditions are hot and dry. When there is a risk of fire or wildfire, do not use a power tool around flammable materials or around dry vegetation or brush. Contact your local fire authorities or the U.S. Forestry Service if you have any question about whether vegetation and weather conditions are suitable for the use of a pole pruner.

WARNING

Never modify your muffler. Any modification could cause an increase in heat radiation, sparks or sound level, thereby increasing the risk of fire, burn injury or hearing loss. You may also permanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only.

WARNING

HT 100, HT 101, HT 130, HT 131

Toreduceriskofburns,donottouchthe 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 (e.g. the trunk of a felled tree) away from any combustible substances.

WARNING

An improperly mounted or damaged cylinder housing or a damaged/deformed muffler shell may interfere with the cooling process of the muffler. To reduce the risk of fire or burn injury, do not continue work with a damaged or improperly mounted cylinder housing or a damaged/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 muffler maintainedby aSTIHLservicing 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.

English

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 process, the muffler does not cool down as rapidly as con- ventional mufflers when the engine returns to idle or is shut off. To reduce the risk of fire and burn injuries when using a cat- alytic 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 materi- als while it is still hot.

Reactive Forces

WARNING

Reactive forces may occur any time the chain is rotating.The force used to cut wood can be reversed and work against the operator. If the rotating chain is suddenly stopped by contact with any solid object such as a branch or is pinched, the reactive forces may occur instantly. These reactive forces may result in loss of control, which, in turn, may cause personal injury. An understanding of the causes of these reactive forces may help you avoid the element of surprise and loss of control.

English

Because of the design of the pole pruner, the reactive forces experienced whenworkingwithitaregenerallynotas severe as those encountered with a chainsaw. Nevertheless, you should always maintain a proper grip and good footing to control the power tool when you experience such forces.

The most common reactive forces are:

–kickback,

–pushback,

–pull-in. Kickback

Kickback may occur when the moving saw chain near the upper quadrant of the bar nose contacts a solid object or is pinched.

002BA230 KN

The reaction of the cutting force of the chain causes a rotational force on the chainsawinthe direction oppositetothe chain movement. This may cause the bar to move upward.

To Avoid Kickback

The best protection from kickback is to avoid kickback situations:

1.Beawareofthelocationoftheguide bar nose at all times.

2.Never let the nose of the guide bar contact any object. Do not cut limbs with the nose of the guide bar. Be especially careful near wire fences and when cutting small, tough limbs, which may easily catch the chain.

3.Cut only one limb at a time.

A = Pull-in

A	001BA037 KN

Pull-in occurs when the chain on the bottom of the bar is suddenly stopped whenitispinched,caughtorencounters a foreign object in the wood. The reaction of the chain pulls the saw forward.

Pull-in frequently occurs when the chain is not rotating at full speed before it contacts the wood.

To Avoid Pull-in

1.Be alert to forces or situations that may cause material to pinch the chain at the bottom of the bar.

2.Always start a cut with the chain rotating at full speed.

B = Pushback

B	001BA038 KN

Pushback occurs when the chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain may drive the saw rapidly straight back toward the operator. Pushback frequently occurs when the top of the bar is used for cutting.

To Avoid Pushback

1.Be alert to forces or situations that may cause material to pinch the chain at the top of the bar.

2.Do not cut more than one limb at a time.

3.Do not twist the bar when withdrawing it from an underbuck cut because the chain can pinch.

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

Always stop the engine and make sure that the chain is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only.

Wear gloves when handling or performing maintenance on the cutting attachment.

WARNING

Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminalofthe proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug terminal and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

HT 100, HT 101, HT 130, HT 131

WARNING

Never test the ignition system with the ignition wire boot removed from the sparkplugorwitharemovedsparkplug, since uncontained sparking may cause a fire.

WARNING

Do not operate your power tool if the mufflerisdamaged,missingormodified. An improperly maintained muffler will increasetheriskoffireandhearingloss. Your muffler is equipped with a sparkarresting screen to reduce the risk of fire; never operate your power tool if the screen is missing, damaged or clogged. Remember that the risk of a brush or forest fire is greater in hot or dry weather.

In California, it is a violation of § 4442 or § 4443 of 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. 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.

The STIHL 4-MIX engine features mixturelubrication and mustberun ona fuel mixture of gasoline and engine oil.

It operates otherwise on the 4-stroke principle.

18	HT 100, HT 101, HT 130, HT 131

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 and should not be used.

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.

Ifyourpowertoolshowsanincorrectidle adjustment, have your STIHL dealer 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 STIHL HP Ultra oil or ask your dealer for an equivalent high quality oil to ensure the maximum performance of the product for the full lifetime.

To meet the requirements of EPA 40CFR90/1054 we recommend to use STIHL HP Ultra oil.

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.

English

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, not to exceed 30 days of storage. 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.

Chain Lubricant

For automatic and reliable lubrication of the chain and guide bar – use only an environmentally compatible quality chain and bar lubricant. Rapidly biodegradable STIHL BioPlus is recommended.

NOTICE

Biological chain oil must be resistant to aging (e.g. STIHL BioPlus), since it will otherwise quickly turn to resin. This results in hard deposits that are difficult to remove, especially in the area of the chaindriveandchain.Itmayevencause the oil pump to seize.

The service life of the chain and guide bar depends on the quality of the lubricant. It is therefore essential to use only a specially formulated chain lubricant.

WARNING

Do not use waste oil. Renewed contact with waste oil can cause skin cancer. Moreover, waste oil is environmentally harmful.

NOTICE

Waste oil does not have the necessary lubricating properties and is unsuitable for chain lubrication.
