Transporting in a vehicle: – Properly secure your power tool to
prevent turnover, fuel spillage and damage.
Fueling
Always shut off the engine before refueling.
Do not fuel a hot engine – fuel may spill and cause a fire.
Always remove the power tool from your back and put it on the ground before refueling. Fuel the unit only when it is standing on the ground.
Open the fuel cap carefully to allow any pressure build-up in the tank to release slowly and avoid fuel spillage.
Fuel your power tool only in well­ventilated areas. If you spill fuel, wipe the machine immediately – if fuel gets on your clothing, change immediately.
Screw-type fuel cap
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.
Check the fuel system for leaks,
paying special attention to visible parts such as the tank cap, hose connections and the manual fuel pump (on machines so equipped). If there are any leaks or damage, do not start the engine – risk of fire. Have your machine repaired by a servicing dealer before using it again.
Throttle trigger must move freely
and spring back to the idle position when released.
The setting lever must move easily
to STOP or 0
The blower tubes must be properly
assembled.
Keep the handles dry and clean –
free from oil and dirt – for safe control of the power tool.
Check that the spark plug boot is
secure – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.
Never attempt to modify the controls
or the safety devices in any way.
Check condition of blower housing. Check condition of harness straps
and backpack – replace damaged or worn straps.
A worn blower housing (cracks, nicks, chips) may result in an increased risk of injury from thrown foreign objects. If the blower housing is damaged, consult your dealer – STIHL recommends you contact a STIHL servicing dealer.
To reduce the risk of accidents, do not operate your power tool if it is not properly assembled and in good condition.
For emergencies: Practice quickly opening the fastener on the waist belt, loosening the shoulder straps and setting down the unit.
Starting the Engine
Start the engine at least 3 meters from the fueling spot, outdoors only.
Your power tool is designed to be operated by one person only. Do not allow other persons in the work area – even when starting.
Do not drop start the power tool – start the engine as described in the instruction manual.
Place the power tool on level ground, make sure you have secure footing, hold the power tool securely.
As soon as the engine starts, the air flow may throw small objects (e.g. stones) in your direction.
Gasoline is an extremely flammable fuel. Keep clear of naked flames. Do not spill any fuel – do not smoke.
Check for leakage. To reduce the risk of serious of fatal burn injuries, do not start or run the engine until leak is fixed.
After fueling, tighten down the screw-type fuel cap as securely as possible.

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.
To reduce the risk of damage to property, also maintain this distance from other objects (vehicles, windows).
When blow-sweeping (in open ground and gardens), watch out for small animals to avoid harming them.
Never leave a running machine unattended.
Take special care in slippery conditions – damp, snow, ice, on slopes and uneven ground.
Watch out for obstacles: Be careful of refuse, tree stumps, roots and ditches which could cause you to trip or stumble.
Never work on a ladder or any other insecure support.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
Work calmly and carefully – in daylight conditions and only when visibility is good. Stay alert so as not to endanger others.
To reduce the risk of accidents, take a break in good time to avoid tiredness or exhaustion.
To reduce the risk of serious or fatal injury from breathing toxic fumes, ensure proper ventilation when working in trenches, hollows or other confined locations.
To reduce the risk of accidents, stop work immediately in the event of nausea, headache, visual disturbances (e.g. reduced field of vision), problems with hearing, dizziness, deterioration in ability to concentrate. Apart from other possibilities, these symptoms may be caused by an excessively high concentration of exhaust gases in the work area.
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.
If dust levels are very high, always wear a suitable respirator.
Operate your power tool so that it produces a minimum of noise and emissions – do not run the engine unnecessarily, accelerate the engine only when working.
After finishing work, put the unit down on a level, non-flammable surface. To reduce the risk of fire, do not put it down near easily combustible materials (e.g. wood chips, bark, dry grass, fuel).
If your power 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 – see also "Before Starting Work". Check the fuel system in particular for leaks and make sure the safety devices are working properly. Do not continue operating your power tool if it is damaged. In case of doubt, consult your servicing dealer.
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.
To reduce the risk of injury from thrown objects, do not allow any other persons within 15 meters of your own position.
Do not direct the air blast towards bystanders or animals since the air flow can blow small objects at great speed.
Your power tool produces toxic exhaust fumes as soon as the engine is running. These fumes may be colorless and odorless and contain unburned hydrocarbons and benzol. Never run the engine indoors or in poorly ventilated loca­tions, even if your model is equipped with a cata­lytic converter.

Always shut off the engine before taking the unit off your back.
Working Technique
To minimize blowing time, use a rake and broom to loosen dirt particles before you start blowing.
Recommended working technique to minimize air pollution:
If necessary, dampen the surface to
be cleaned in order to avoid creating too much dust.
Do not blow particles in the direction
of bystanders, in particular in the direction of children, pets, open windows or freshly washed vehicles. Take special care in such situations.
Remove the blow-swept debris in
rubbish bins – do not blow it onto the neighbor's land.
Recommended working technique to minimize noise:
Operate your power tool at
reasonable times only – not early in the morning, late at night or during midday rest periods when people could be disturbed. Observe local rest periods.
Operate blowers at the lowest
engine speed necessary to accomplish the task.
Check your blower before starting
work. Pay special attention to the muffler, air intakes and air filter.
Vibrations
Prolonged use of the power tool may result in vibration-induced circulation problems in the hands (whitefinger disease).
No general recommendation can be given for the length of usage because it depends on several factors.
The period of usage is prolonged by:
Keeping your hands warm Work breaks
The period of usage is shortened by: – Any personal tendency to suffer
from poor circulation (symptoms: frequently cold fingers, itching).
Low outside temperatures. Gripping force (a tight grip hinders
circulation).
Continual and regular users should monitor closely the condition of their hands and fingers. If any of the above symptoms appear (e.g. tingling sensation in fingers), seek medical advice.
Maintenance and Repairs
Service the machine regularly. Do not attempt any maintenance or repair work not described in the instruction manual. Have all other work performed by a servicing dealer.
STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. STIHL dealers are
regularly given the opportunity to attend training courses and are supplied with the necessary technical information.
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.
STIHL recommends the use of genuine STIHL replacement parts. They are specifically designed to match your model and meet your performance requirements.
To reduce the risk of injury, always shut off the engine before carrying out any maintenance or repairs or cleaning the machine. – Exception: Carburetor and idle speed adjustments.
Do not turn the engine over on the starter with the spark plug boot or spark plug removed since there is otherwise a risk of fire from uncontained sparking.
Do not service or store your machine near open flames.
Check the fuel filler cap for leaks at regular intervals.
Use only a spark plug of the type approved by STIHL and make sure it is in good condition – see "Specifications".
Inspect the ignition lead (insulation in good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to hearing, do not operate your machine if the muffler is damaged or missing.
Do not touch a hot muffler since burn injury will result.
