STIHL offers a comprehensive range of personal protective clothing and equipment.
Transporting the Power Tool
Always shut off the engine before carrying the unit long distances.
Carry the unit in the normal working position: Power tool on your back, left hand on the loop handle and the right hand on the control handle – even if you are left-handed – cutting attachment lowered close to ground. Fit transport guard on metal cutting attachments to avoid the risk of injury from blade contact
Avoid touching hot parts of the machine, especially the muffler and gear housing – you could suffer serious burns.
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.
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.
Your power tool comes standard with either a screw-type or bayonet-type fuel cap.
After fueling, tighten down the screw-type fuel cap as securely as possible.
Insert the fuel cap with hinged grip (bayonet-type cap) correctly in the opening, turn it clockwise as far as stop and fold the grip down.
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.
Use only an approved combination
of cutting attachment, deflector and handle. All parts must be assembled properly and securely.
Slide control / stop switch must
move easily to STOP or 0
Smooth action of throttle trigger
lockout and throttle trigger – the throttle trigger must return automatically to the idle position.
Check that the spark plug boot is
secure – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.
Cutting tool or attachment: Check
for correct and secure assembly and good condition.
Check protective devices (e.g.
deflector for cutting tool, rider plate) for damage or wear. Always replace damaged parts. Do not operate your machine with a damaged deflector or worn rider plate (lettering and arrows no longer legible).
Wear heavy-duty gloves.

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 seri-
ous of fatal burn injuries, do not start or
run the engine until leak is fixed.
FR 480 C
English

Never attempt to modify the controls
or the safety devices in any way.
Keep the handles dry and clean –
free from oil and dirt – for safe control of the power tool.
Adjust straps and loop handle to suit
your height and reach – see chapter on "Fitting the Backpack".
To reduce the risk of personal injury, do not operate your power tool if it is damaged or not properly assembled.
For emergencies: Practise 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.
Select firm ground in an open area. Make sure you have good balance and secure footing. Power tool on your back. The cutting attachment must be clear of the ground and all other obstructions because it may begin to run when the engine starts.
Your power tool is designed to be operated by one person only. Do not allow other persons within 15 meters of your own position – even when starting.
Start the engine only as described in the instruction manual.
Check idle speed setting: The cutting attachment must not rotate when the engine is idling with the throttle trigger released.
To reduce the risk of fire, keep hot exhaust gases and hot muffler away from easily combustible materials (e.g. wood chips, bark, dry grass, fuel).
Holding and Controlling the Power Tool
Make sure you always have good balance and secure footing.
Carry the powerhead on your back.
Always hold the drive tube firmly with both hands on the handles – right hand on control handle and left hand on loop handle – and always keep the drive tube on the right side of your body – left­handers, too.
During Operation
In the event of impending danger or in an emergency, switch off the engine immediately by moving the slide control / stop switch to STOP or 0.
To reduce the risk of personal injury , do not allow any other persons within a radius of 15 meters of your own position. To reduce the risk of damage to property, also maintain this distance from other objects (vehicles, windows).
The correct engine idle speed is important to ensure that the cutting attachment stops rotating when you let go of the throttle trigger. Check and correct the idle speed setting at regular intervals. If the cutting attachment still rotates at idle speed, have your dealer make proper adjustments or repairs.
Take special care in slippery conditions – damp, snow, ice, on slopes or uneven ground.
Watch out for obstacles: Roots, tree stumps or holes which could cause you to trip or stumble.
Make sure you always have good balance and secure footing.
Never work on a ladder or in a tree.
Never operate your unit with one hand.
To reduce the risk of injury, avoid contact with
the cutting attachment.
Note that the cutting attachment continues to run for a short period after you let go of the throttle trigger – fly-
wheel effect.

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 accidents, take a break in good time to avoid tiredness or exhaustion.
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 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.
Operate your power tool so that it produces a minimum of noise and emissions – do not run the engine unnecessarily, accelerate the engine only for cutting.
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.
The dusts, vapor and smoke produced during operation may be dangerous to health. If dust levels are very high, wear a suitable respirator.
The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gearbox housing.
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". 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, have the machine checked by your servicing dealer.
Special care must be taken when working in difficult, over-grown terrain.
When cutting high scrub, under bushes and hedges: Keep cutting tool at minimum height of 15 cm to avoid harming small animals.
Before leaving the power tool unattended: Shut off the engine.
Check the cutting attachment at regular short intervals during operation or immediately if there is a noticeable change in cutting behavior:
Turn off the engine. Hold the unit
firmly and press the cutting attachment into the ground to bring it to a standstill.
Check condition and tightness, look
for cracks.
Check sharpness.
Replace damaged or dull cutting
attachments immediately, even if they have only superficial cracks.
Clean grass and plant residue off the cutting attachment mounting at regular intervals – remove any build up of material from the cutting attachment and deflector.
To reduce the risk of injury, shut off the engine before replacing the cutting attachment.
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.
To reduce the risk of injuryfrom thrown objects, never operate the unit without the proper deflector for the type of cutting attachment being used.
Inspect the work area: Stones, pieces of metal or other solid objects can be thrown and cause per­sonal injury or damage the cutting attachment and property (e.g. parked vehicles, windows).
FR 480 C
English

Do not continue using or attempt to repair damaged or cracked cutting attachments by welding, straightening or modifying the shape (out of balance).
This may cause parts of the cutting blade to come off and hit the operator or bystanders at high speed and result in
serious or fatal injuries.
When using mowing heads
Equip the deflector with the additional components specified in the instruction manual.
Use only the deflector with properly mounted line limiting blade to ensure the mowing lines are automatically trimmed to the approved length.
To reduce the risk of injury, always turn off the engine before adjusting the nylon line of manually adjustable mowing heads
Using the unit with over-long nylon cutting lines reduces the motor's operating speed. The clutch then slips continuously and this causes overheating and damage to important components (e.g. clutch, polymer housing components) – and this can increase the risk of injury from the cutting attachment rotating while the engine is idling.
When using metal cutting tools
STIHL recommends the use of original STIHL metal cutting attachments. They are specifically designed to match your model and meet your performance requirements.
Metal cutting attachments rotate at very high speed. The forces that occur act on the machine, the attachment and the material being cut.
Sharpen metal cutting attachments regularly as specified.
Unevenly sharpened metal cutting attachments cause out-of-balance which can impose extremely high loads on the machine and increase the risk of breakage.
Dull or improperly sharpened cutting edges can put a higher load on the cutting attachment and increase the risk of injuryfrom cracked or broken parts.
Inspect metal cutting attachments for cracks or warping after every contact with hard objects (e.g. stones, rocks, pieces of metal). To reduce the risk of injury, remove burrs and other visible build-ups of material (use a file) because they may become detached and be thrown at high speed during operation.
To reduce the above-mentioned risks when using a metal cutting attachment, never use a metal cutting attachment with a diameter larger than specified. It must not be too heavy. It must be manufactured from materials of adequate quality and its geometry must be correct (shape, thickness).
To reduce the risk of injury, a metal cutting attachment not manufactured by STIHL must not be heavier, thicker, have a different shape or a diameter larger than the largest metal cutting attachment approved by STIHL for this power tool model.
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:
Hand protection (wearing warm
gloves)
Work breaks
The period of usage is shortened by:
Any personal tendency to suffer
from poor circulation (symptoms: frequently cold fingers, tingling sensations).
Low outside temperatures.
The force with which the handles
are held (a tight grip restricts 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 original 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 enginebefore carrying out any maintenance or repairs or cleaning the machine. – Exception: Carburetor and idle speed adjustments.
To reduce the risk of fire caused by unconfined sparking outside the cylinder, do not press the starter switch if the spark plug boot has been removed or the spark plug unscrewed.
To reduce the risk of fire, 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.
Vibration behavior is influenced by the condition of the AV elements – check the AV elements at regular intervals.
Symbols on Deflectors
An arrow on the deflector shows the correct direction of rotation of the cutting attachments.
Mowing Head with Nylon Lines
For trimming around fence posts, trees, etc. – less risk of damaging tree bark.
STIHL Polycut Mowing Head with Polymer Blades
For mowing unobstructed edges of meadows (without posts, fences, trees or similar obstacles).
Check the wear limit marks!
Use deflector in combination with mowing heads only. Do not use metal cutting attachments.
To reduce the risk of injury, never use steel wire in place of the nylon cutting line.
002BA331 KN
FR 480 C
English

If one of the wear limit marks on the PolyCut mowing head is worn through (arrow): Do not continue using the mowing head. Install a new one. There is otherwise a risk of injury from thrown parts of the head.
It is important to follow the maintenance instructions for the Polycut mowing head.
Risk of Kickout (Blade Thrust) with Metal Cutting Attachments
When using metal cutting attachments (grass cutting blade, brush knife) there is a risk of kickout when the rotating blade comes into contact with a solid object such as a tree trunk, branch, tree stump, rock or similar. The machine is thrown to the right or to the rear – opposite to the attachment's direction of rotation.
The risk of kickout is greatest when the black area of the rotating cutting attachment comes into contact with a solid object.
Grass Cutting Blade
Use for grass and weeds only – sweep the brushcutter in an arc like a scythe.
Resharpen the grass cutting blade according to instructions when it has dulled noticeably.
Brush Knife
Suitable for cutting matted grass, wild growth and scrub, thinning young stands with a maximum stem diameter of 2 cm. To reduce the risk of personal injury, never attempt to cut thicker wood.
To cut wild growth and scrub, lower the brush knife down onto the growth to achieve shredding effect – do not use the cutting attachment above waist height.
Exercise extreme caution when using this method of cutting. The higher the cutting attachment is off the ground, the greater the risk of injury from cuttings being thrown sideways.
Use the brushcutter like a scythe (sweep it to the right and left) at ground level when cutting grass and thinning young stands.
Warning! Improper use of a brush knife may cause it to crack, chip or shatter – risk of injury from thrown parts.
To reduce the risk of injury it is essential to take the following precautions:
