Some special safety pre
cautions must be observed to reduce the risk of personal injury when operating this power tool because of the very high speed of its cut
ting attachment.
It is important that you read the instruction man
ual before first use and keep it in a safe place for future reference. Nonobservance of the instruction manual may result in serious or even fatal injury.
Observe all applicable local safety regulations, standards and ordinances.
If you have not used this type of power tool before: Have your dealer or other experienced user show you how it is operated or attend a special course in its operation.
Minors should never be allowed to use a power tool.
Keep bystanders, especially children, and animals away from the work area.
When the power tool is not in use, shut it off so that it does not endanger others.
Secure it against unauthorized use.
The user is responsible for avoiding injury to third parties or damage to their property.
FR 460 TC-M
Do not lend or rent your power tool without the instruction manual. Be sure that anyone using it understands the information contained in this manual.
The use of noise emitting power tools may be restricted to certain times by national or local regulations.
To operate the power tool you must be rested, in good physical condition and mental health.
If you have any condition that might be aggravated by strenuous work, check with your doctor before operating a power tool.
Persons with pacemakers only: The ignition system of your power tool produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. STIHL recommends that persons with pacemakers consult their physician and the pacemaker manufacturer to reduce any health risk.
Do not operate the power tool if you are under the influence of any substance
(drugs, alcohol) which might impair vision, dexterity or judgment.
Depending on the cutting attachment fitted, use your power tool only for cutting grass, wild growth, shrubs, scrub, bushes, small diameter trees and similar materials.
Do not use your power tool for any other purpose because of the increased risk of accidents.
Only use cutting attachments and accessories that are explicitly approved for this power tool model by STIHL or are technically identical. If you have any questions in this respect, consult a servicing dealer. Use only high quality tools and accessories in order to avoid the risk of accidents and damage to the machine.
STIHL recommends the use of genuine
STIHL tools and accessories. They are specifically designed to match the product and meet your performance requirements.
The deflector on this power tool cannot protect the operator from all objects thrown by the cutting attachment
(stones, glass, wire, etc.). Such objects may ricochet and then hit the operator.
Never attempt to modify your machine in any way since this may increase the risk of personal injury. STIHL excludes all liability for personal injury and damage to property caused while using unauthorized attachments.
Do not use a pressure washer to clean your power tool. The solid jet of water may damage parts of the power tool.
Clothing and Equipment
Wear proper protective clothing and equipment.
Clothing must be sturdy but allow complete free
dom of movement. Wear snug-fitting clothing, an overall and jacket combi
nation, do not wear a work coat.
Avoid clothing that could get caught on branches or brush or moving parts of the machine. Do not wear a scarf, necktie or jewelry. Tie up and confine long hair
(e.g. with a hair net, cap, hard hat, etc.).
English
Wear steel-toed safety boots with non-slip soles.
Sturdy shoes with non-slip soles may be worn as an alternative only when using mowing heads.
WARNING
To reduce the risk of eye injuries, wear close-fit
ting safety glasses in accordance with Euro
pean Standard EN 166.
Make sure the safety glasses are a comforta
ble and snug fit.
Wear a face shield and make sure it is a good fit. A face shield alone does not provide adequate eye protection.
Wear hearing protection, e.g. earplugs or ear muffs.
Wear a safety hard hat for thinning operations, when working in high scrub and where there is a danger of head injuries from falling objects.
Wear robust work gloves made of durable material
(e.g. leather).
STIHL offers a comprehensive range of personal protective clothing and equipment.

English
Transporting the Power Tool
Turn off the engine before transporting the unit over distances of more than about 50 meters.
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.
To reduce the risk of cut injuries, fit transport guard on the cutting attachment, even when carrying the tool for short distances – see also
"Transporting the Unit".
To reduce the risk of seri
ous burn injuries, avoid touching hot parts of the machine, including the gearbox housing.
Transporting by 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.
Always shut off the engine before refueling.
Do not fuel a hot engine – fuel may spill and cause a fire.
–
Place the power tool with the support frame on the ground, filler opening faces away from back padding – see "Fueling".
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 fuel tank cap as securely as possible.
This reduces the risk of unit vibrations causing the fuel cap to loosen or come off and spill quantities of fuel.
To reduce the risk of serious or fatal burn injuries, check for fuel leakage. If fuel leakage is found, do not start or run the engine until leak is fixed.
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.
–
Use only an approved combination of cutting attachment, deflector and handle. All parts must be assembled properly and securely.
–
The stop switch / slide control must move freely.
–
Check smooth action of choke knob, throttle trigger lockout and throttle trigger – the throttle trigger must return automatically to the idle position. The choke lever must spring back from the
}
position to the run position
F
when the throttle trigger lockout and throttle trigger are squeezed.
–
Check that the spark plug boot is secure – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.
4 FR 460 TC-M
–
Check cutting tool or attachment for correct and secure assembly and good condition.
–
Check protective devices (e.g. deflector for cutting attachment, 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).
–
Never attempt to modify the controls or 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".
–
Check condition of carrying system and the straps - replace if damaged or worn.
To reduce the risk of accidents, do not operate your power tool if it is damaged or not properly assembled.
For emergencies: Practice quickly opening the fastener on the waist belt, loosening the shoulder straps and setting down the unit. To avoid damage, do not throw the unit to the ground when practicing.
Starting the Engine
Start the engine at least 3 meters from the fueling spot, outdoors only.
Place the powerhead on firm ground in an open area. Make sure you have good balance and secure footing. Hold the powerhead securely. The cutting attachment must be clear of the ground and all other obstructions because it may begin to run when the engine starts.
Observe information in chapter on
"Starting / Stopping the Engine".
Your power tool is a one-person unit. To reduce the risk of injury from thrown objects, do not allow other persons within a radius of 15 meters of your own position – even when starting.
To reduce the risk of injury, avoid contact with the cutting attachment.
Do not drop start the power tool – start the engine as described in the instruction manual.
English
Note that the cutting attachment continues to run for a short period after you let go of the throttle trigger – flywheel effect.
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. To reduce the risk of injury, put the powerhead on your back only after starting and making sure the cutting attachment is not rotating.
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 – even if you are left-handed.
During Operation
Make sure you always have good balance and secure footing.
FR 460 TC-M 5
English
In the event of impending danger or in an emergency, switch off the engine immediately – move the stop switch / slide control in the direction of 0.
15m (50ft)
To reduce the risk of personal injury from thrown objects, 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 regularly. If the cutting attachment continues to rotate when the engine is idling, have the machine checked by your servicing dealer. STIHL recommends an authorized STIHL servicing dealer.
Take special care in slippery conditions
(ice, wet ground, snow) – on slopes or uneven ground.
Watch out for obstacles: Roots and tree stumps which could cause you to trip or stumble.
Never work on a ladder or in a tree.
Never operate your power tool with one hand.
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.
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 loca
tions, even if your model is equipped with a cata
lytic converter.
Ensure proper ventilation when working in trenches, hollows or other confined locations. This reduces the risk of serious or fatal injury from breathing toxic fumes.
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 when working.
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 the work area is very dusty or smoky, wear a respirator.
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, consult your servicing dealer.
Do not operate your power tool in the starting throttle position – engine speed cannot be controlled in this position.
To reduce the risk of injury from thrown objects, never operate the unit without the proper deflector for the type of cutting attachment being used.
6 FR 460 TC-M
Inspect the work area:
Stones, pieces of metal or other solid objects can be thrown and cause per sonal injury or damage the cutting attachment and property (e.g. parked vehicles, windows).
-
Special care must be taken when working in difficult, over-grown terrain.
When cutting high scrub, under bushes and hedges: Keep cutting attachment at a 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 wait for the cutting attachment to come 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 changing the cutting attachment.
The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gearbox housing.
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.
Using metal cutting attachments
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.
FR 460 TC-M
English
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 injury from 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.
If a rotating metal cutting attachment makes contact with a rock or other solid object there is a risk of sparking which may cause easily combustible material to catch fire under certain circumstances. Dry plants and scrub are also easily combustible, especially in hot and dry weather conditions. If there is a risk of fire, do not use metal cutting attachments near combustible materials, dry plants or scrub. Always contact your local forest authority for information on a possible fire risk.
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 attachment to come off and hit the operator or bystanders at high speed and result in serious or fatal injuries.
7
English
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 from unintentional engine startup, always shut off the engine and disconnect the spark plug boot before performing any repairs, maintenance or cleaning work. –
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.
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.
Some of the following symbols are applied to the outside of the deflector to indicate the approved combination of cutting attachment and deflector.

English
Risk of Kickout (Blade Thrust) with Metal
Cutting Attachments
Grass Cutting Blade
WARNING
When using metal cut
ting attachments 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.
Use the brushcutter like a scythe (sweep it to the right and left) at ground level when cutting grass and thinning young stands.
The risk of kickout is greatest when the black area of the rotating cutting attachment comes into contact with a solid object.
Use for grass and weeds only – sweep the brushcutter in an arc like a scythe.
WARNING
Improper use may damage the grass cutting blade – risk of injury from thrown parts.
Resharpen the grass cutting blade according to instructions when it has dulled noticeably.
Brush Knife
For cutting matted grass, wild growth and scrub and thinning young stands with a stem diameter of no more than
2 cm – do not cut thicker stems – risk of accidents.
To cut wild growth and scrub, lower the brush knife down onto the growth to achieve a shredding effect – always keep the cutting attachment below hip level during this process.
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.
Warning! Improper use of a brush knife may cause it to crack, chip or shatter – risk of injury from thrown parts.
10 FR 460 TC-M
To reduce the risk of injury it is essential to take the following precautions:
–
Avoid contact with stones, rocks, pieces of metal and other solid foreign objects.
–
Never cut wood or shrubs with a stem diameter of more than 2 cm – use a circular saw blade for such work.
–
Inspect the brush knife at regular short intervals for signs of damage.
Do not continue working with a damaged brush knife.
–
Resharpen the brush knife regularly and whenever it has dulled noticeably, and have it balanced if necessary (STIHL recommends a
STIHL servicing dealer).

Fuel
Your engine requires a mixture of gasoline and engine oil.
WARNING
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.
STIHL MotoMix uses STIHL HP Ultra two-stroke engine oil for an extra long engine life.
MotoMix is not available in all markets.
Mixing Fuel
NOTICE
Unsuitable fuels or lubricants or mix ratios other than those specified may result in serious damage to the engine.
Poor quality gasoline or engine oil may damage the engine, sealing rings, hoses and the fuel tank.
Gasoline
Use only high-quality brand-name gasoline with a minimum octane rating of 90 – leaded or unleaded.
If your machine is equipped with a catalytic converter, you must use unleaded gasoline.
NOTICE
A few tankfuls of leaded gasoline will greatly reduce the efficiency of the catalytic converter.
Gasoline with an ethanol content of more than 10% can cause running problems in engines with a manually adjustable carburetor and should not be used in such engines.
Engines equipped with M-Tronic deliver full power when run on gasoline with an ethanol content of up to 25% (E25).
Engine oil
Use only high-quality two-stroke engine oil – preferably STIHL HP, HP Super or
HP Ultra, which are specially formulated for use in STIHL engines. HP Ultra guarantees high performance and a long engine life.
These engine oils are not available in all markets.
Use only STIHL 50:1 two-stroke engine oil for the fuel mix in models with a catalytic converter.

Operating Instructions Air filter
3
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-ofservice periods – see "Storing the
Machine".
General Information
The filter has a very long service life.
Do not remove the filter cover or replace the air filter as long as there is no noticeable loss of power.
Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.

Filter Element for Winter Operation
Maintenance and care of the special filter element for winter operation are described in the chapter on "Winter
Operation".
M-Tronic Winter Operation
General Information
The M-Tronic controls fuel feed and ignition timing electronically in all operating conditions.
M
-
Tronic guarantees simple and fast starts. The engine is started in the
Start
}
position irrespective of climatic conditions or engine temperature. After starting, the Start
}
position can be maintained until the engine runs smoothly.
M-Tronic ensures optimum engine power at all times, very good acceleration and automatic adjustment to suit changing conditions.
For this reason there is no need to change the carburetor setting – the carburetor has no adjusting screws.
If the usual good running behavior and engine power are not reached after an extreme change in operating conditions, contact your servicing dealer for assistance.
STIHL recommends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer.
