BR 200 |
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 blowers. Different models may have 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.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.
Safe use of a blower 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 white finger 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 white finger 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 white finger disease. In order to reduce the
English
risk of white finger 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.
–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 handle with constant, excessive pressure. Take frequent breaks.
All the above-mentioned precautions do not guarantee that you will not sustain white finger 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 standard).
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.
Clothing must be sturdy and snug-fitting, but allow complete freedom of movement.
Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become drawn into the air intake. Secure hair so it is above shoulder level.
4
Good footing is very important. Wear sturdy boots with nonslip soles. Steel-toed safety boots are recommended.
Warning!
To reduce the risk of injury when the inhalation of dust cannot be substantially controlled use an appropriate respirator for the material being blown. For more information see the "Working conditions" section of these Safety Precautions.
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 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.
Warning!
Small particles (e.g. dust) blown through the blower tubes and nozzle can cause a static charging of the blower tubes.
This is especially true in low humidity and high dust conditions.
In order to reduce the risk of shock from static charging and subsequent injury from loss of control, STIHL offers an optional kit for use in especially dry and dusty conditions. Contact your STIHL dealer for information regarding special accessories that may be available for your product.
If your blower is properly assembled and you are still experiencing static shocks, make sure that your footwear has conductive soles and try operating your unit without gloves, which may be interfering with the conduction of the charge.
THE USE OF THE POWER TOOL
Transporting the Power Tool
Warning!
Always switch off the engine before taking the machine off your back and putting it 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 oilgasoline mixture for fuel (see the chapter on "Fuel" of your instruction manual).
BR 200
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 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 clothing. If this happens, change your clothing immediately.
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.
English
Before Starting
Warning!
Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, setting lever and momentary stop switch. 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 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 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!
To reduce the risk of injury from parts thrown by the fan wheel, check the fan housing for damage (cracks or holes that could allow foreign objects to contact the fan wheel). If any such damage is found, stop using the unit and contact your STIHL dealer for repair.
BR 200 |

English
Warning!
Adjust carrying harness to suit your size before starting work.
In an emergency, you may slip out of the harness and throw off the machine quickly. Try slipping out of the harness a number of times before using the machine in order to become accustomed to it. Do not throw off the machine while practicing as it could damage the machine.
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.
Warning!
Your power tool is a one-person
machine. To reduce the risk of eye or other injury from
thrown objects, insure that bystanders are at least 50 feet (15 m) away during use. Stop operation immediately if you are approached.
Warning!
This unit is equipped with an ignition system that is normally in operational readiness. After the setting lever is used to stop the engine, it automatically springs back to the "on" position. If the engine is warm, it may be possible to start it by simply pulling the starter rope, with no further adjustments. To reduce the risk of injury, be particularly alert to keep children away from the unit.
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!
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.
Once the engine has started, immediately blip the throttle trigger, which should cause the choke knob to move to the run position and allow the engine to slow down to idle.
During Operation
Holding and Controlling the Power
Tool
0009BA001 KN
The blower is designed for singlehanded operation with the right hand on the control handle. It should be carried as a backpack with the straps of the harness over both shoulders.
Warning!
To reduce the risk of loss of control, never carry the unit with the strap(s) over one shoulder.
Wrap your fingers tightly around the handle, keeping the control handle cradled between your thumb and forefinger. Keep your hand in this position to have your machine under control at all times.
Warning!
Special care must be taken in slippery conditions (wet ground) and in difficult, overgrown terrain. Watch for hidden obstacles such as tree stumps, roots, rocks, holes and ditches to avoid stumbling. For better footing, clear away fallen branches, scrub and cuttings. Be extremely cautious when working on slopes or uneven ground.
6 |
BR 200 |
To reduce the risk of stumbling and loss of control, do not walk backward while operating the machine.
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 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. If exhaust fumes become concentrated due to insufficient ventilation, clear obstructions 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 dust and other airborne contaminants, in particular those with a smaller particle 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 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.
Warning!
If the substance being blown is a commercial substance, review the material safety data sheet for that substance and / or consult the material manufacturer / supplier. The state of California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, etc.
English
Warning!
Breathing asbestos dust is dangerous and can cause severe or fatal illness, respiratory illness or cancer. The use and disposal of asbestos-containing products have been strictly regulated by OSHA and the Environmental Protection Agency. If you have any reason to believe that you might be blowing or otherwise disturbing asbestos, immediately contact your employer or a local OSHA representative.
Warning!
Dust with silica in its composition may contain crystalline silica. Silica is a basic component of sand, quartz, brick, clay, granite and numerous other minerals and rocks, including masonry and concrete products. Repeated and / or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory disease, including silicosis. In addition, the state of California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When encountering such materials, always follow the respiratory precautions mentioned above.
Operating Instructions
Warning!
In the event of an emergency, switch off the engine immediately – move the setting lever to †or STOP.
BR 200 |
7 |
English
Warning!
Even though bystanders should be kept away from the running power tool, never work alone. Keep within calling distance of others in case help is needed.
Stop the engine immediately if you are approached.
Warning!
To reduce the risk of personal injury, do not direct air blast towards bystanders, since the high pressure of the air flow can injure eyes and can blow small objects at great speed.
Warning!
The blower fan between the air intake and output openings rotates whenever the engine is running.
Never insert any foreign object into the air intake of the machine or into the nozzle of the blower. It will damage the fan wheel and may cause serious injury to the operator or bystanders as a result of the object or broken parts being thrown out at high speed.
Do not place the blower on the ground when operating at high speed, because small objects such as sand, grass, dust, etc. may be pulled into the air intake and damage the fan wheel. It is best to turn the machine off when putting it on the ground.
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.
Warning!
To reduce the risk of fire and burn injury, 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!
Never modify your muffler. The muffler could be damaged and cause an increase in heat radiation or sparks, thereby increasing the risk of fire and burn injury. You may also permanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only.
Catalytic converter
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, the following specific safety precautions must be observed.
Warning!
Since a muffler with a catalytic converter cools down less rapidly than conventional mufflers, 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.
Warning!
An improperly mounted or damaged cylinder housing or a damaged/deformed muffler shell may interfere with the cooling process of the catalytic converter. 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 catalytic converter is furnished with screens designed to reduce the risk of fire from the emission of hot particles. Due to the heat from the catalytic reaction, these screens will normally
8 |
BR 200 |
stay clean 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.
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 section in this instruction manual.
Please refer to the maintenance chart in this instruction manual.
Warning!
Always stop the engine and make sure that the fan 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 this instruction manual. Have such work performed by your STIHL servicing dealer only.
Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine.
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 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.
Warning!
Never test the ignition system with the 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 or the Public Resources Code to use or operate gasoline-powered tools on forest-covered, brush-covered or
English
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.
Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use.
For maintenance items please also refer to the maintenance chart in this instruction manual.
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 instruction manual.
Store fuel in an approved and properly labeled safety-type canister only. Take care when handling gasoline! For health and safety reasons, avoid direct contact with the skin and avoid inhaling fuel vapor!

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.
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 with a manually adjustable carburetor and should not be used in such engines.
The ethanol content in gasoline affects engine running speed – it may be necessary to readjust the carburetor if you use fuels with various ethanol contents.
BR 200 |
11 |
English
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 only STIHL two-stroke engine oil or equivalent high-quality two-stroke engine oils that are designed for use only in air cooled two-cycle engines.
We recommend STIHL HP Ultra 2-Cycle Engine Oil since it is specially formulated for use in STIHL engines.
Do not use BIA or TCW rated (twostroke water cooled) mix oils or other 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 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".

Engine Management
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.

Adjusting the Carburetor
The carburetor comes from the factory with a standard setting.
This setting provides an optimum fuel-air mixture under most operating conditions.
With this carburetor it is only possible to adjust the high speed screw within fine limits.
Standard Setting
9928BA012 AM
N Shut off the engine.
NCheck the air filter and replace it if necessary.
NCheck that the throttle cable is properly adjusted – readjust if necessary – see chapter on "Adjusting the Throttle Cable".
NHave the spark arresting screen (not all markets) checked – see “Inspection and Maintenance by Dealer"
NTurn high speed screw (H) counterclockwise as far as stop (no more than 3/4 turn).
English
NTurn the low speed screw (L) carefully clockwise as far as stop, then turn it back 1 turn.
N Start and warm up the engine.
Adjusting Idle Speed
Engine stops while idling
N Check the standard setting.
NTurn the idle speed screw (LA) slowly clockwise until the engine runs smoothly.
9928BA013 AM
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) slowly counterclockwise until the engine runs and accelerates smoothly.
Erratic idling behavior
Idle setting is too rich:
NTurn the low speed screw (L) clockwise until the engine runs and accelerates smoothly.
It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L).

English
Fine Tuning for Operation in Mountains or at Sea Level
A slight correction of the setting may be necessary if engine power is not satisfactory when operating at high altitude or at sea level.
N Check the standard setting. N Warm up the engine.
At high altitude
NTurn high speed screw (H) clockwise (leaner) – no further than stop.
If the setting is too lean there is a risk of engine damage due to
insufficient lubrication and overheating.
At sea level
NTurn high speed screw (H) counterclockwise (richer) – no further than stop.
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

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

If engine running behavior is unsatisfactory even though the air filter is clean and the carburetor is properly adjusted, the cause may be the muffler.
Have the muffler checked for contamination (carbonization) by your servicing dealer.
STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.
To help prolong the wear life of the starter rope, observe the following points:
NPull the starter rope only in the direction specified.
NDo not pull the rope over the edge of the guide bushing.
NDo not pull out the rope more than specified.
NDo not allow the starter grip to snap back, guide it back into the housing slowly – see chapter on "Starting / Stopping the Engine."
Have a damaged starter rope replaced by your dealer before it breaks completely. STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.
