Frequently Asked Questions - FC 110 STIHL

What type of fuel does the Stihl FC 110 use?

The FC 110 requires a mixture of unleaded gasoline (minimum 89 octane, up to 10% ethanol) and Stihl two-stroke engine oil at a ratio of 50:1. Use mid-grade gasoline and Stihl HP Ultra oil for best results.

How do I start the engine on the FC 110?

To start: press the trigger lockout and throttle trigger, move slide control to START, release triggers. For cold start, set choke knob to closed position, press manual fuel pump at least five times. Place unit on ground, pull starter rope briskly. Once engine fires, turn choke knob to open position, blip throttle to idle.

How do I adjust the cutting depth on the Stihl FC 110?

Shut off the engine. Loosen the wingnut counterclockwise, move the depth wheel upward to increase depth or downward to reduce depth. The blade should just touch the ground or break the surface by no more than 5 mm (0.2 in). Tighten the wingnut securely.

What is the correct idle speed for the FC 110?

The idle speed should be set so that the cutting blade does not rotate when the engine is idling. The specified idle speed is 2,800 rpm. If the blade turns, adjust the idle speed screw (LA) counterclockwise until it stops, then another 1/2 to 3/4 turn.

How often should I clean or replace the air filter?

Clean the air filter weekly or after every refueling stop if operating in dusty conditions. Replace the filter element if it is damaged or excessively dirty. Use only a new Stihl filter element.

How do I replace the cutting blade on the FC 110?

Shut off the engine and remove the spark plug boot. Remove the blade mounting screw (left-hand thread) using the combination wrench and stop pin. Position the new blade on the thrust plate, ensuring the collar engages the mounting hole. Reinstall the thrust washer and screw, tightening firmly counterclockwise.

What spark plug does the FC 110 use?

Use a resistor-type spark plug, specifically Bosch USR 7 AC. The electrode gap should be 0.5 mm (0.02 in). Replace the spark plug after approximately 100 operating hours or if electrodes are eroded.

How do I store the Stihl FC 110 for long periods?

Drain and clean the fuel tank in a well-ventilated area. Run the engine until the carburetor is dry to prevent diaphragms from sticking. Thoroughly clean the machine, especially cylinder fins and air filter. Remove the cutting blade, clean it, and store the unit in a dry, locked location out of reach of children.

What safety features does the FC 110 have?

Key safety features include a throttle trigger lockout (must be depressed to operate), a slide control with START/STOP positions, a deflector to redirect debris away from the operator, a skirt to reduce flung objects, and a wear guard protecting the gearbox.

What is the warranty on the FC 110 emissions system?

Stihl provides a two-year emissions control system warranty for the FC 110. This covers defects in materials and workmanship on emission-related parts such as the carburetor, ignition system, fuel system, and muffler. Repairs must be performed by an authorized Stihl dealer.

Safety Precautions and Working Techniques

Because an edger is a high-speed, fast-cutting power tool, 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.

WARNING

As more fully explained later in these Safety Precautions, to reduce the risk of personal injury, make sure your unit is equipped with the proper handle, harness and deflector. Use only cutting attachments that are specifically authorized by STIHL for use on your FC 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 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. If the rotating blade comes in contact with your body, it will cut you. When it comes in contact with solid foreign objects such as rocks or bits of metal, it may fling them directly or by ricochet in the direction of bystanders or the operator. Striking such objects could damage the cutting attachment and may cause blades to crack, chip or break. Thrown objects, including broken blades, may result in serious or fatal injury to the operator or bystanders.

Use your edger only for edging in grass, weeds and soft green plants.

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 bystanders 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 edgers. Different models may have

different parts and controls. See the appropriate section of your instruction manual for a description of the controls and function of the parts of your model.

Safe use of an edger 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 disease (Raynaud's phenomenon) or carpal tunnel syndrome.

English

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 factors in the development of whitefinger 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.

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.

WARNING

To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protective glasses with adequate top and side protection complying with ANSI Z87 "+" (or your applicable national standard). If there is a risk of injury to the operator's face, STIHL also recommends that you also wear a face shield or face screen over your goggles or protective glasses.

WARNING

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 metal blades. 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 are recommended.

Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.

THE POWER TOOL

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

FC 95, FC 110

WARNING

Never modify this power tool in any way. Only attachments supplied by STIHL and expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthorized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous.

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. Check in particular that 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. In case of doubt, have it checked by your STIHL servicing dealer.

Transporting the Power Tool

WARNING

To reduce the risk of injury from loss of control and blade contact, never carry or transport your power tool with the cutting attachment moving.

It may be carried only in 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.

WARNING

Always shut off the engine and make sure that the cutting attachment has stopped before putting an edger down. When transporting it in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the unit.

Fuel

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

English

WARNING

Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and serious 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 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 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 on your power tool carefully so as to allow any pressure build-up in the tank to release slowly. Never remove the fuel filler cap while the engine is running.

Select bare ground for fueling and move 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 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

In order to reduce the risk of fuel spillage and fire from an improperly tightened fuel cap, correctly position and tighten the fuel cap in the fuel tank opening.

WARNING

Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities 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.

Before Starting

WARNING

Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger lockout, stop switch, cutting blade, deflector and harness. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices. Never use a power tool that is damaged or not properly maintained.

WARNING

Check fuel system for leaks, especially the visible parts, e.g., filler cap, hose connections, manual fuel pump (only for power tools equipped with a manual fuel 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

Do not attach any cutting attachment to a unit without proper installation of all required parts. Failure to use the proper parts may cause the blade to fly off and seriously injure the operator or bystanders.

WARNING

The cutting attachment must be properly tightened and in safe operating condition. Inspect for loose parts (nuts, screws, etc.) and for cracked, bent, warped or damaged blades. Replace damaged blades before using the power tool.

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

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.

WARNING

To reduce the risk of personal injury to the operator from blade contact and thrown objects, make sure your unit is equipped with the proper deflector, handle and harness.

Technical line drawing of a mechanical component with an arrow indicating direction (no text or symbols)

An arrow on the deflector shows the correct direction of rotation of the cutting blade.

The arrow on the deflector must always face away from you, so that cuttings and other debris will be diverted away from the machine and your position (see chapter "Working Techniques".)

Adjust carrying harness and hand grip to suit your size before starting work. The machine should be properly balanced as specified in your instruction manual for proper control and less fatigue in operation. To be better prepared in case of an emergency, practise releasing the unit from the harness as quickly as possible.

Starting

WARNING

Start the engine at least 10 feet (3 m) from the fueling spot, outdoors only.

For specific starting instructions, see the appropriate section of your manual. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing.

WARNING

To reduce the risk of injury from blade contact, be absolutely sure that the cutting attachment is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and move the cutting attachment.

Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle 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.)

WARNING

Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting.

WARNING

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

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 attachment, do not use your unit with incorrect idle adjustment. At correct idle speed, the cutting attachment should not move. For

English

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.

During Operation

Holding and Controlling the Power Tool

Illustration of a person holding a stringed object with black bands, no text or symbols present

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

Your right hand should grip the rear handle. This also applies to left-handers.

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

Never attempt to operate 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 attachment with your hand or any other part of 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, overgrown terrain. Watch for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. For better 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 chemicals, such as unburned hydrocarbons (including benzene) and carbon monoxide, that are known to cause respiratory problems, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury / illness from inhaling toxic fumes, never run the machine indoors or in poorly ventilated locations.

WARNING

If the vegetation being cut or the surrounding 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. Substantial or repeated inhalation of dust and other airborne contaminants, in particular those with a smaller particle size, may cause respiratory or other illnesses. Control dust at the source

where possible. Use good work practices, 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 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 near the ambient (background) level, the operator and any bystanders should wear a respirator approved by NIOSH / MSHA for the type 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 engine immediately – move the slide control / 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 ricochet a great distance.

To reduce the risk of eye and other injury 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 of damage to property, also maintain this distance from such objects as vehicles or windows. Even maintaining a minimum distance of 15 meters cannot exclude the potential danger. Any coworkers who must be in the restricted area should also wear goggles or protective glasses. Stop the engine immediately if you are approached.

WARNING

Inspect the work area: To reduce the risk of injury, remove stones, pieces of metal and other solid objects which could be thrown 15 meters or more by the cutting attachment or damage the cutting attachment and property (e.g. parked vehicles, windows).

WARNING

During cutting, check the tightness and the condition of the cutting attachment at regular short intervals with the engine and attachment stopped. If the behavior of the attachment changes during use, stop the engine immediately, wait until

the cutting attachment stops, and check the nut securing the attachment for tightness and the blade for cracks, wear and damage.

WARNING

A loose blade may vibrate, crack, break or come off the edger, which may result in serious or fatal injury. Make sure that the cutting attachment is properly tightened. Use the wrench supplied or one of sufficient length to obtain the proper torque. If the blade loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. If the blade continues to loosen, see your STIHL dealer. Never use an edger with a loose cutting attachment.

WARNING

Replace a cracked, bent, warped, damaged, dull or worn out blade immediately, even if damage is limited to superficial cracks. Such attachments may shatter at high speed and cause serious or fatal injury.

WARNING

When using your edger, avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the power tool to kick out or could cause damage to the blade.

WARNING

If a rotating metal blade strikes a rock or other hard object, sparks may be created, which can ignite flammable materials under certain circumstances.

English

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 metal blades 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 metal blade.

WARNING

If the blade or deflector becomes clogged or stuck, always shut off the engine and make sure the cutting attachment has stopped before cleaning. Grass, weeds, etc. should be cleaned off the blade at regular intervals.

WARNING

To reduce the risk of unintentional rotation of the cutting attachment and injury, always shut off the engine before replacing the cutting attachment.

WARNING

The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing when it is hot.

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

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

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. If your gas/oil mix ratio is correct (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 experience loss of performance and you suspect a clogged screen, have your muffler maintained by a STIHL servicing dealer. Some state or federal laws or regulations may require a properly maintained spark arrestor for certain uses. See the "Maintenance, Repair and 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 catalytic 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 conventional mufflers when the engine returns to idle or is shut off. To reduce the risk of fire and burn injuries 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 cutting attachment and instructions on proper mounting see the chapter on "Replacing the Cutting Blade" in your instruction manual.

WARNING

To reduce the risk of severe or fatal injury from blade contact and / or loss of control, never attempt to use a metal blade on an FC model for which it is not authorized.

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 parts for maintenance and repair. Use of 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 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 blades.

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 detachable 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 spark plug boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire.

WARNING

Do not operate your power tool if the muffler is damaged, missing or modified. 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 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 governmental entities/agencies, such as 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 attachments 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.

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.

English

Using the Unit

Line drawing of a person using a tool to clean or sweep debris on a paved surface (no text or symbols)

Your power edger is designed to produce sharp contoured borders around lawns and flower beds. It will cut almost all types of grass, weeds and soft green plants.

Preparations

If the work area is very dry, spray it lightly with water: this softens the soil and ensures that less dust is created. Slightly damp green plants are easier to cut.

WARNING

Clear away all obstacles and solid objects from the work area.

●Plan the best route for edging. Always hold and operate your edger on the right-hand side of your body.

WARNING

Do not adjust the deflector.

The deflector has been set at the factory so that the arrow on the deflector and the open side point away from the

operator. This ensures that cuttings and other debris are directed away from the power tool and operator.

Edging

• Start the engine.
  ●Start the cut at no less than half throttle and continue cutting at full throttle.
  ●Hold and guide your power tool so that the blade is vertical.
  ●Cut steadily so that the engine is not lugged down – do not apply force.
  ●Operate at no more than a normal walking pace.
  ●Do not push the blade into the ground.

●Always walk forwards when cutting, do not pull the unit towards you.
●Cut at a steady pace to avoid having to make several passes.

●Use the gunning sight (1) to line the blade up with the edge of the bed.

●Fit the screw (6) in the shaft counterclockwise and tighten it down firmly.

Fuel

This engine is certified to operate on unleaded gasoline and the STIHL two-stroke engine oil at a mix ratio of 50:1.

Your engine requires a mixture of high-quality gasoline and two-stroke air cooled engine oil.

Use mid-grade unleaded gasoline with a 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.), but magnesium castings and 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.

If your power tool shows an incorrect idle 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 (two-stroke water cooled) mix oils or other mix oils that state they are for use in both 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 container on the ground before filling. 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, 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.

Operating Instructions

During break-in period

A factory-new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.

During Operation

After a long period of full throttle operation, allow the engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload.

After Finishing Work

Storing for a short period: Wait for the engine to cool down. Empty the fuel tank and keep the machine in a dry place, well away from sources of ignition, until you need it again. For longer out-of-service periods – see "Storing the Machine".

Cleaning the Air Filter

If there is a noticeable loss of engine power

●Turn the choke knob to
●Take out the screw (1) and remove the filter cover (2).
●Clean away loose dirt from around the filter.
●Grip the filter element (3) at the cutout (arrow) in the filter housing (4) and remove it.
●Fit a new filter element. As a temporary measure you can knock it out on the palm of your hand or blow it out with compressed air. Do not wash.
●Replace damaged parts.

Installing the filter

●Install the filter element in the filter housing and fit the cover.
- Insert the screw and tighten it down firmly.

Engine Management Adjusting the Carburetor

Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware.

The carburetor of the machine has been adjusted for optimum performance and fuel efficiency in all operating states at the factory.

Setting the idle speed

Engine stops when idling

• Let the engine warm up for approx. 3 min
• Slowly turn idle speed screw (LA) clockwise until the engine runs smoothly – the cutting attachment must not rotate

Cutting attachment turns when idling

●Turn the idle speed screw (LA) slowly counterclockwise until the cutting attachment stops moving – then turn another 1/2 to 3/4 turn in the same direction

WARNING

If the cutting attachment continues to keep rotating in idle even after adjustment, have the machine checked by a servicing dealer.

English

Spark Arresting Screen in Muffler

In some countries the muffler is equipped with a spark arresting screen.

• If the engine is down on power, check the spark arresting screen in the muffler.
  ●Wait for the muffler to cool down.
• Move the slide control to STOP-0.

Technical line drawing of a mechanical component with no visible text or symbols

●Take out the screw (1).

●Take out the screws (2) and remove the shroud (3).

●Take out the screw (4).
●Lift the spark arresting screen (5) and pull it out.
●Clean the spark arresting screen. If the screen is damaged or heavily carbonized, fit a new one.
●Refit the spark arresting screen.
●Insert the screw and tighten it down firmly.
●Fit the shroud.

Spark Plug

If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug.

Fit a new spark plug after approx. 100 operating hours or earlier if the electrodes are badly eroded.

Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation.

Removing the spark plug

- Move the slide control to STOP-0.

●Pull off the spark plug boot (1).
●Unscrew the spark plug.

Checking the Spark Plug

●Clean dirty spark plug.
- Check electrode gap (A) and readjust if necessary – see chapter "Specifications."
●Use only resistor type spark plugs of the approved range.

Rectify problems which have caused fouling of spark plug:

– too much oil in fuel mix,
– dirty air filter,
– unfavorable running conditions, e.g. operating at part load.

WARNING

To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press spark plug boot (1) snugly onto spark plug terminal (2) of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug boot and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

Installing the spark plug

●Screw home the spark plug, fit the boot and press it down firmly.

Storing the Machine

For periods of 3 months or longer

●Drain and clean the fuel tank in a well ventilated area.
●Dispose of fuel properly in accordance with local environmental requirements.
- Run the engine until the carburetor is dry – this helps prevent the carburetor diaphragms sticking together.
●Thoroughly clean the machine – pay special attention to the cylinder fins and air filter.
- Remove, clean and inspect the cutting blade.
●Store the machine in a dry, high or locked location, out of the reach of children and other unauthorized persons.

STIHL Incorporated California Exhaust and Evaporative Emissions Control Warranty Statement

For California only

Your Warranty Rights and Obligations

The California Air Resources Board (CARB) and STIHL Incorporated are pleased to explain the emission control system warranty on your 2015 and later small off-road equipment engine.

In California, new equipment that uses small off-road engines must be designed, built, and equipped to meet the State's stringent anti-smog standards. STIHL Incorporated must warrant the emissions control system on your small off-road engine for the period listed below provided there has been no abuse, neglect or improper maintenance of your small off-road engine.

Your emissions control system may include parts such as the carburetor or fuel-injection system, the ignition system, and catalytic converter. Also included may be hoses, belts, connectors or other emission-related assemblies.

Where a warrantable condition exists, STIHL Incorporated will repair your small off-road equipment engine at no cost to you including diagnosis, parts and labor.

Manufacturer's Warranty Responsibilities

This emissions control system is warranted for two years in California. If any emissions-related part on your equipment is defective, the part will be repaired or replaced by STIHL Incorporated free of charge.

Owner's Warranty Responsibilities

As the small off-road equipment engine owner, you are responsible for performance of the required maintenance listed in your instruction manual. STIHL Incorporated recommends that you retain all receipts covering maintenance on your small off-road equipment engine, but STIHL Incorporated cannot deny warranty solely for the lack of receipts or your failure to ensure the performance of all scheduled maintenance.

As the small off-road equipment engine owner, you should however be aware that STIHL Incorporated may deny you warranty coverage if your small off-road equipment engine or a part has failed due to abuse, neglect, or improper maintenance or unapproved modifications.

You are responsible for presenting your small off-road equipment engine to a STIHL servicing dealer as soon as the problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have any questions regarding your warranty rights and responsibilities, please contact a STIHL customer service representative at 1-800-467-8445 or you can write to

STIHL Inc., 536 Viking Drive, P.O. Box 2015, Virginia Beach, VA 23450-2015.

Coverage by STIHL Incorporated

STIHL Incorporated warrants to the ultimate purchaser and each subsequent purchaser that your small off-road equipment engine is designed, built and equipped, at the time of sale, to meet all applicable emission regulations.

STIHL Incorporated also warrants to the initial purchaser and each subsequent purchaser that your engine is free from defects in materials and workmanship which cause the engine to fail to conform to applicable emission regulations for a period of two years.

Defects Warranty Period

The warranty periods will begin on the date the utility equipment engine is purchased by the initial purchaser. If any emission-related part on your engine is defective, the part will be replaced by STIHL Incorporated at no cost to the owner.

Add-on or modified parts that are not exempted by CARB may not be used. The use of any non-exempted add-on or modified parts will be grounds for disallowing a warranty claim. STIHL Incorporated will not be liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.

English

The warranty on emissions-related parts will be interpreted as follows:

1. Any warranted part that is not scheduled for replacement as required maintenance in the written instructions required in the Emission Warranty Parts List (see below) must be warranted for the warranty period defined in Subsection COVERAGE BY STIHL INCORPORATED, see above. If any such part fails during the period of warranty coverage, it must be repaired or replaced by the manufacturer according to Subsection (4) below. Any such part repaired or replaced under the warranty must be warranted for the remaining warranty period.
2. Any warranted part that is scheduled only for regular inspection in the written instructions required by the Emission Warranty Parts List (see below) must be warranted for the warranty period defined in Subsection COVERAGE BY STIHL INCORPORATED, see above. A statement in such written instructions to the effect of "repair or replace as necessary" will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty must be warranted for the remaining warranty period.
3. Any warranted part that is scheduled for replacement as required maintenance in the written instructions required by the Emission Warranty Parts List (see below) must be warranted for the period of time prior to the first scheduled replacement point for

that part. If the part fails prior to the first scheduled replacement, the part must be repaired or replaced by the engine manufacturer according to Subsection (4) below. Any such part repaired or replaced under warranty must be warranted for the remainder of the period prior to the first scheduled replacement point for the part.

1. Repair or replacement of any warranted part under the warranty must be performed at a warranty station at no charge to the owner.
2. Notwithstanding the provisions of Subsection (4) above, warranty services or repairs will be provided at all manufacturer distribution centers that are authorized to service the subject engines.
3. The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective, provided that such diagnostic work is performed at a warranty station.

Warranty Work

STIHL Incorporated shall remedy warranty defects at any authorized STIHL servicing dealer or warranty station. Any such work shall be free of charge to the owner if it is determined that a warranted part is defective. Any manufacturer approved or equivalent replacement part may be used for any warranty maintenance or repairs on emission-related parts and must be provided without charge to the owner. STIHL Incorporated is liable for damages to other engine components caused by the failure of a warranted part still under warranty.
