Safety Precautions and
Working Techniques
Because this KombiEn- gine is the engine for a high-speed power tool, 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 manuals and the safety precautions of your KombiEngine and KombiTool 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 with- out the instruction manuals. Be sure that anyone using it understands the infor- mation contained in these manuals.
Use your power tool only for the applications described in the instruction manual of the KombiTool you are using.
English
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 your power tool run unattended. When it 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 power tools. Different models may have different parts and controls. See the appropriate section of your
KombiEngine and KombiTool instruction manuals for a description of the controls and the function of the parts of your model.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.

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 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 – not while using KombiTool BG-KM – 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 the risk of serious or fatal injury, persons with a pacemaker should consult their physician and the pacemaker manufac- turer before operating this tool.
Proper Clothing
Warning!
To reduce the risk of injury, the operator should wear proper protective apparel.
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.

KM 110 R, KM 130 R |
Avoid loose-fitting jack- ets, 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.
For further instructions on proper clothing see the safety precautions in the instruction manual of the KombiTool you are using.
THE POWER TOOL
For illustrations and definitions of the power tool parts see the chapter on "Main Parts."
Warning!
Never modify this power tool in any way. Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL KombiEngine 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.
KM 110 R, KM 130 R
THE USE OF THE POWER TOOL
Transporting the Power Tool
Warning!
Always switch off the engine and make sure the working tool has stopped before putting a power tool down. When transporting your power tool in a vehi- cle, properly secure it to prevent turnover, fuel spillage and damage to the power tool.
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 combustible 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 refu- eling. 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 dur-
ing 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 cloth- ing. If this happens, change your clothing immediately.

English
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.
001BA220 KN
To do this with this STIHL cap, raise the grip on the top of the cap until it is upright 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
NIf the cap does not drop fully into the opening when the positioning marks line up and/or if the cap does not tighten properly when twisted, the base of the cap may be prematurely rotated (in relation to the top) to the closed position. Such misalignment can result from handling, cleaning or an improper attempt at tightening.

tioned for installation |
001BA226 KN |
NTo return the cap to the open position for installation, turn the cap (with the grip up) until it drops fully into the tank opening. Next, twist the cap counterclockwise as far as it will 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.

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 attachment, 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.
Warning!
Never operate your power tool if it is damaged, improperly adjusted or main- tained, 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 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.
Starting
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 KombiEngine and KombiTool manuals.
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 loss of control, be absolutely sure that the working tool 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 working tool.
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.
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.
English
See also the safety precautions on Starting in the instruction manual of the
KombiTool.
Important Adjustments
Warning!
To reduce the risk of personal injury from loss of control or contact with the running working tool, do not use a power tool with incorrect idle adjust- ment. At correct idle speed, the working tool should not move. For directions on how to adjust idle speed, see the appro- priate 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
002BA057 KN
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.
KM 110 R, KM 130 R |
7 |
English
Warning!
To reduce the risk of injury from loss of control, never work on a ladder or on any other insecure support.
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 gen-
erates 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!
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 and other airborne contaminants, in par- ticular those with a smaller particle size, 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 associations with respect to dust ("particulate mat- ter"). 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!
Never modify your muffler. Any modifi- cation 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 cyl- inder housing or a damaged/deformed muffler shell may interfere with the cool- ing 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 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. If your gas/oil mix ratio is correct
8 |
KM 110 R, KM 130 R |
(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 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.
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
KM 110 R, KM 130 R
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 section of your KombiEngine and KombiTool instruction manuals. Please refer to the maintenance charts respectively the maintenance notes in these manuals.
Warning!
Always stop the engine and make sure that the working tool 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 KombiEngine and
KombiTool instruction manuals. Have such work performed by your STIHL servicing dealer only.
English
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 terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose con- nection between spark plug boot and the ignition wire connector in the boot may create arcing that could ignite com- bustible fumes and cause a fire.
Warning!
Never test the ignition system with the ignition wire 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 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 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 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.
9
English
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.
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 this manual.

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 (twostroke 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 3 months 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 enginemounted 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".

–The low speed screw (L) is 3/4 turn open.
N Start and warm up the engine.
NAdjust idle speed with the idle speed screw (LA) so that the cutting attachment does not move.
Adjusting Idle Speed
It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw
(L).
NWarm up the engine for about 3 minutes.
Engine stops while idling
NTurn the idle speed screw (LA) slowly clockwise until the engine runs smoothly – the cutting attachment must not move.
Cutting attachment runs when engine is idling
NTurn the idle speed screw (LA) counterclockwise until the cutting attachment stops running and then turn the screw about another 1/2 to 3/4 turn in the same direction.
If the working tool or cutting attachment continues to run when the engine is idling, have your machine checked and repaired by your servicing dealer.
Erratic idling behavior, engine stops even though setting of LA-screw has been corrected, poor acceleration
Idle setting is too lean:
NTurn the low speed screw (L) counterclockwise, no further than stop, until the engine runs and accelerates smoothly.
Erratic idling behavior
Idle setting is too rich
NTurn the low speed screw (L) clockwise, no further than stop, until the engine runs and accelerates smoothly.
Version B: Fine Tuning
A slight correction of the setting of the high speed screw (H) may be necessary if engine power is not satisfactory when operating at high altitude, sea level or after changing the working tool.
Rule of thumb:
Turn the high speed screw (H) about one quarter turn for every 1000m (3300 ft) change in altitude.
KM 110 R, KM 130 R
Conditions for adjustment
NCarry out the standard setting without disturbing the high speed screw (H).
NWarm up the engine for about 3 minutes.
N Open the throttle wide.
At high altitude
NTurn the high speed screw (H) clockwise (leaner), no further than stop, until there is no further noticeable increase in engine speed.
At sea level
NTurn the high speed screw (H) counterclockwise (richer), no further than stop, until there is no noticeable increase in engine speed.
It is possible that maximum engine speed may be reached with the standard setting.

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
N Move the slide control to STOP-0.
