English The use of noise emitting power tools may be restricted to certain times by national or local regulations. Do not operate your power tool if any of its components are damaged. Do not use a pressure washer to clean your power tool. The solid jet of water may damage parts of the power tool. Accessories and replacement parts Only use parts and accessories that are explicitly approved for this power tool by STIHL or are technically identical.
English Transporting in a vehicle: – Properly secure your power tool to prevent turnover, fuel spillage and damage. Fueling Gasoline is an extremely flammable fuel. Keep clear of naked flames. Do not spill any fuel – do not smoke. This reduces the risk of unit vibrations causing the fuel cap to loosen or come off and spill quantities of fuel. Before Starting Check that your power tool is properly assembled and in good condition – refer to appropriate chapters in the instruction manual.
English During Operation In the event of impending danger or in an emergency, switch off the engine immediately by moving the setting lever to STOP or 0. Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted. To reduce the risk of fire, do not smoke while operating or standing near your power tool. Note that combustible fuel vapor may escape from the fuel system.
English 0009BA001 KN Using the Blower The machine is carried as a backpack. Hold and control the blower tube with your right hand on the control handle. Walk slowly forwards as you work – observe the nozzle outlet at all times – do not walk backwards – risk of stumbling. Always shut off the engine before taking the machine off your back. Working Technique Vibrations To minimize blowing time, use a rake and broom to loosen dirt particles before you start blowing.
English Only use high-quality replacement parts in order to avoid the risk of accidents and damage to the machine. If you have any questions in this respect, consult a servicing dealer. Shut off the engine before rectifying problems. Assembling the Unit Mounting the Control Handle STIHL recommends the use of genuine STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements.
English Mounting the Hose Clamps and Pleated Hose Mounting the Blower Tubes 5 2 BR 500 1 Depending on your size and reach: Push blower tube (1) up to the appropriate mark on the blower tube (2). N Rotate the blower tube (1) in the direction of the arrow and engage it in the appropriate slot (3). N N Push the hose clamp (1) (with retainer for throttle cable) onto the elbow (3) – the positioning marks must face to the left.
English Mounting the nozzle Adjusting the Control Handle Wear Mark on Nozzle 452BA111 KN 1 N Push the nozzle (1) onto the blower tube (2) and engage it on the lugs (3).

Fitting the Transport Aid When storing or transporting the machine: 1 N Rotate the nozzle (1) in the direction of the arrow until the lugs (3) are covered.
English Adjusting the Throttle Cable Fitting the Harness It may be necessary to correct the adjustment of the throttle cable after assembling the machine or after a prolonged period of operation. N Secure the blower tube to the handle on the backplate. Adjust the throttle cable only when the unit is completely and properly assembled. N Adjust the harness straps so that the backplate fits snugly and securely against your back.
English Loosening the harness straps Fuel Your engine requires a mixture of gasoline and engine oil. 373BA004 KN WARNING N Lift the tabs of the sliding adjusters. For health reasons, avoid direct skin contact with gasoline and avoid inhaling gasoline vapor. STIHL MotoMix STIHL recommends the use of STIHL MotoMix. This ready-to-use fuel mix contains no benzol or lead, has a high octane rating and ensures that you always use the right mix ratio.
English Storing Fuel Filling up with fuel Fueling Store fuel only in approved safety-type fuel canisters in a dry, cool and safe location protected from light and the sun. Fuel mix ages – only mix sufficient fuel for a few weeks work. Do not store fuel mix for longer than 30 days. Exposure to light, the sun, low or high temperatures can quickly make the fuel mix unusable. Take care not to spill fuel while fueling and do not overfill the tank.
English Winter Operation Information Before You Start 3 NOTICE 452BA086 KN 4 At temperatures below 10°C: N Swing the shutter (4) to the winter position (r). N Tighten down the screw (3) firmly. N Refit the filter cover and air filter element. At temperatures above 20°C: 1 Base plate (BR 600) – Intake screen between backplate and engine Positions of Setting Lever The power tool is equipped with different types of control handle.
English Ignition is interrupted, engine stops. The setting lever (1) is not locked in this position. It springs back to position “F”. The ignition is switched on again. Fixed throttle Starting / Stopping the Engine Starting the Engine N 452BA115 KN Position “†” Observe safety precautions. NOTICE 2 0416BA013 KN 1 N Start your unit on a clean, dust-free surface only to ensure that no dust is sucked in.

English 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 helps protect enginemounted components (ignition, carburetor) from thermal overload. Replacing the Air Filter Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.
English Erratic idling behavior, engine stops even though setting of LA screw has been corrected, poor acceleration Standard Setting Adjusting the Carburetor N Shut off the engine. Machines without Adjustable Carburetor N Check the air filter and clean or replace if necessary. On certain machine versions it is no longer necessary to adjust the carburetor. Such machines have no setting symbol on the shroud.
English Checking the Spark Plug N If the engine is down on power, difficult to start or runs poorly at idle speed, first check the spark plug. N Fit a new spark plug after about 100 operating hours – or sooner if the electrodes are badly eroded. Install only suppressed spark plugs of the type approved by STIHL – see "Specifications". Removing the Spark Plug N Installing the spark plug A 2 N Clean dirty spark plug. N Check electrode gap (A) and readjust if necessary – see "Specifications".
English Storing the Machine For periods of 3 months or longer N Drain and clean the fuel tank in a well ventilated area. N Dispose of fuel properly in accordance with local environmental requirements. N Run the engine until the carburetor is dry – this helps prevent the carburetor diaphragms sticking together. N Thoroughly clean the machine – pay special attention to the cylinder fins and air filter.
