2 Safety Precautions
2 Safety Precautions
This special chain saw shall be used only by persons who are trained in special cutting and working techni- ques. Due to the special handle design (closely spaced handles) there is an increased risk of injury using this kind of saw (cut injuries due to uncontrol- led reactive forces of the chain saw). Special safety precautions must be observed to reduce the risk of per- sonal injury when working with a chainsaw because of the very high chain speed and very sharp cutters. It is important that you read the instruction manual before first use and keep it in a safe place for future reference. Non- observance of the instruction manual may result in seri- ous or even fatal injury.
2.1 General
Observe all applicable local safety regulations, standards and ordinances.
The use of noise emitting power tools may be restricted to certain times by national or local regulations.
If you have not used this model before: Have your dealer or other experienced user show you how to operate your machine or attend a special course in its operation.
Minors should never be allowed to use a chain- saw. Exceptions to this rule are young persons older than 16 who have been trained in special cutting techniques with the tree surgery saw.
Keep bystanders, especially children, and ani- mals away from the work area.
The user is responsible for avoiding injury to third parties or damage to their property.
Do not lend or rent your chain saw without the instruction manual. All users must be specially trained in tree surgery work with a tree surgery saw and be familiar with this model and its oper- ation.
To operate a chain saw 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 chainsaw.
Do not operate the chain saw if you are under the influence of any substance (drugs, alcohol) which might impair vision, dexterity or judgment.

English
To reduce the risk of accidents or injury, put off the work in poor weather conditions (rain, snow, ice, wind).
Persons with pacemakers only: The ignition sys- tem of your chainsaw produces an electromag- netic field of a very low intensity. This field may interfere with some pacemakers. To reduce health risks, STIHL recommends that persons with pacemakers consult their physician and the pacemaker manufacturer before operating this power tool.
2.2 Intended Use
Tree surgery chainsaws are special chainsaws with a handle on the top especially for tree sur- gery and cutting tasks in the crowns of living trees.
Tree maintenance tasks may only be carried out with appropriate safeguards (e. g. lift bucket, per- sonal protective equipment, fall arrest system).
The chainsaw may be used for cutting wood and wooden objects only.
The ring serves to secure the chainsaw on a chainsaw stop featuring overload protection and to transport the saw into the tree at the strap or using a rope.
Do not the chainsaw for any other purpose ­ risk of accidents!
They are not for typical tree felling or cutting fire- wood. Conventional chainsaws with wider spaced handles must be used for these tasks.
Never attempt to modify your chainsaw 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.
2.3 Clothing and Equipment
Wear proper protective clothing and equipment. Clothing must be sturdy and snug-fit- ting, but allow complete freedom of movement. Wear snug-fitting clothing with cut-retardant pads for feet, legs, hands and forearms ­ an overall, not a loose-fitting jacket.
Avoid clothing that could get caught on branches, brush or moving parts of the machine. Do not wear a scarf, necktie or jewelery. Tie up and confine long hair (headscarf, cap, hard hat, etc.).

English

Wear suitable safety shoes ­ with cutretardant material, non-slip soles and steel toe caps.

WARNING
To reduce the risk of eye injuries, wear tight-fitting safety goggles con- forming to standard EN 166. Make sure that the safety goggles fit cor- rectly.
Wear a face shield and make sure it fits cor- rectly.
Wear “personal” hearing protection ­ for exam- ple, ear defenders.
Wear a hard hat with a chin strap wherever there is any risk of falling objects.
Wear sturdy protective gloves made of a resistant material (e.g. leather) ­ with cut-retardant material.
STIHL can supply a comprehensive range of per- sonal protective clothing and equipment.
Use a personal fall arrest system.
Use only certified equipment that is suitable for the application concerned.
Check the condition of the equipment before use and replace broken parts.
2.4 Transporting
Always stop the engine, engage the chain brake and fit the chain guard (scabbard) before carry- ing the saw short distances. This avoids the risk of the chain running unintentionally.

Always carry the saw by the control handle ­ with the hot muffler away from your body ­ the guide bar must point to the rear. To reduce the risk of serious burn injuries, avoid touching hot parts of the machine, especially the surface of the muf- fler.

2 Safety Precautions
In vehicles: Properly secure your saw to prevent turnover, fuel spillage and damage.
2.5 Cleaning
Clean plastic parts with a cloth. Harsh detergents can damage the plastic.
Clean the dust and dirt off the machine ­ do not use any grease solvents for this purpose.
Clean the ventilation slots if necessary.
Do not use a high-pressure cleaner to clean the machine. The hard jet of water can damage parts of the machine.
2.6 Accessories
Only use those tools, guide bars, chains, chain sprockets, accessories or technically equivalent components that have been approved by STIHL for this machine. If you have any questions in this respect, consult a servicing dealer. Use only high quality tools and accessories. Otherwise, there may be a risk of accidents and damage to the machine.
STIHL recommends the use of genuine STIHL tools, guide bars, chains, chain sprockets and accessories. They are specifically designed to match your model and meet your performance requirements.
2.7 Refuelling
Gasoline is an extremely flammable fuel ­ keep clear of naked flames and fire ­ do not spill any fuel ­ no smok- ing.
Switch off the engine before refuelling.
Never refuel the machine while the engine is still hot ­ the fuel may spill over ­ risk of fire!
Open the fuel filler cap carefully so that any excess pressure is relieved gradually and fuel does not splash out.
The machine may only be refuelled in a well ven- tilated place. Clean the machine immediately if fuel is spilled. Do not spill fuel over your clothing ­ contaminated clothing must be changed imme- diately.
The machines can be equipped with the follow- ing filler caps as standard:
Cliplock filler cap (bayonet-type) Place the cliplock filler cap (bayonettype) in position, turn as far as stop and fold the cliplock down.

0458-599-0121-D

2 Safety Precautions
This helps reduce the risk of unit vibrations caus- ing an incorrectly tightened filler cap to loosen or come off and spill quantities of fuel.
Look out for leaks! Never start the engine if fuel has been spilled or is leaking ­ Fatal burns may result!
2.8 Before Starting Work
Check that your chainsaw is properly assembled and in good condition ­ refer to appropriate chapters in the User Manual. ­ Check the fuel system for leaks, paying spe-
cial attention to visible parts such as the fuel cap, hose connections and the manual fuel pump (on chainsaws with manual fuel pump). Do not start the engine if there are leaks or damage ­ risk of fire! Have your chainsaw repaired by an authorized dealer before using it again. ­ Functional chain brake, front hand guard ­ Correctly mounted guide bar ­ Correctly tensioned saw chain ­ Ring is not damaged ­ Throttle trigger and throttle trigger lockout must move easily ­ throttle trigger must return to initial position when released ­ Master control lever can be easily set to STOP, 0 or ­ Check that the spark plug boot is secure ­ a loose boot may cause sparking that could ignite combustible fumes and cause a fire! ­ Never attempt to modify the controls or safety devices. ­ Keep the handles dry and clean ­ free from oil and dirt ­ important for safely guiding the chainsaw. ­ Use chainsaw with an undamaged ring ­ Make sure there is sufficient fuel and chain lubricant in the tanks
Exclusively use the chainsaw in a safe condition ­ risk of accident!
2.9 Starting the Saw
Start the saw on level ground only. Make sure you have a firm footing. Hold the saw firmly. To reduce the risk of injury from the rotating chain, check that the cutting attachment is not touching any object or the ground .
The chainsaw is a one-person saw. Do not allow other persons in the work area ­ even when starting.
Do not attempt to start the saw when the saw chain is in a cut.
0458-599-0121-D

English
Starting the saw in a tree is very dangerous since the user may lose control of the machine ­ risk of injury. The tree surgery saw should be checked, fueled, started and warmed up by an assistant on the ground before it is transported up to the operator in the tree. Start the engine at least 3 meters from the fuel- ing spot, outdoors only. To reduce risk of chain rotation and personal injury, lock the chain with the chain brake before starting. Do not drop start the power tool ­ start the engine as described in the instruction manual.
2.10 While Working
When working in a tree, always secure the tree surgery chainsaw with a rope (tie to hinged ring) and attach it to the lifeline. Always engage the chain brake before releasing the chainsaw and allowing it to hang on the rope. Secure chainsaw with a chainsaw stop installed using the ring. Chainsaw stop must be equipped with overload protection. Suitable accessories are available from authorized dealers
H L
Hold chainsaw with both hands ­ increased risk of accident: right hand on control handle ­ even if you are left-handed. To ensure safe control, wrap your fingers tightly around both handles. One-handed operation is particularly dangerous, e.g. when cutting dry, knotty and dead wood, the chain may not enter the cut properly. The resul- tant reactive forces may cause the saw to skate or bounce on the limb and slide out of control. Increased risk of kickback ­ risk of fatal injury! Use the tree surgery chainsaw with one hand only: ­ if two-handed cutting is not possible and
5

0012BA019 KN

English
­ if one hand is required for support during the cut and
­ if the chainsaw is held firmly and ­ if all parts of your body are clear of the exten-
ded swiveling range of the chainsaw.
During one-handed cutting: ­ never support yourself on the limb being cut ­ never cut with the bar nose ­ Do not try to hold falling branches
Make sure you always have a firm and secure footing. Take special care when the bark is wet ­ danger of slipping!
In the event of impending danger or in an emer- gency, switch off the engine immediately by mov- ing the master control lever/stop switch to STOP, 0 or .
Do not let the chainsaw run unattended.
Exercise caution with slippery surfaces, water, snow, ice, steep slopes, uneven ground or green wood that has just been stripped of its bark ­ danger of slipping!
Exercise caution with tree stumps, roots and ditches ­ tripping hazard!
Do not work alone ­ keep within calling distance of others who are trained in emergency proce- dures and can provide help in an emergency. Helpers at the cutting site must also wear protec- tive clothing (hard hat) and stand well clear of the branches being cut.
Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.
Take breaks when you start getting tired or feel- ing fatigue ­ risk of accidents!
Dust (e. g., sawdust), fumes and smoke pro- duced while using the machine may be hazard- ous to health. Wear a dust mask in case of dust production.
When the engine is running: Note that the saw chain continues to rotate for a short period after you let go of the throttle trigger ­ coasting effect.
No smoking when working with or near the chainsaw – risk of fire! Combustible fuel vapor may escape from the fuel system.
Check the saw chain at regular short intervals during operation or immediately if there is a noticeable change in cutting behavior: ­ Shut off the engine and wait until the saw
chain comes to a complete standstill. ­ Check condition and proper mounting.
6

2 Safety Precautions
­ Ensure that the cutting blades are sharp
Do not touch the saw chain while the engine is running. If the saw chain becomes jammed by an obstruction, switch off the engine immediately before attempting to remove the obstruction ­ risk of injury.
Always turn off the engine before leaving the chainsaw unattended.
Switch off the engine to change the saw chain. Risk of injury from the motor starting unintention- ally!
Keep highly flammable materials (e. g. wood chips, bark, dry grass, fuel) away from hot exhaust gases and hot mufflers ­ risk of fire!Muf- flers with catalytic converters can become espe- cially hot.
Never work without chain lubrication ­ monitor the oil level in the oil tank. Stop work immediately if the oil level in the oil tank is too low and top up with chain oil ­ see also “Topping up with chain oil” and “Checking chain lubricant”.
If the chainsaw 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 in particular that the fuel system has no leaks and the safety equipment is fully operative. Do not continue using a chainsaw that is not in perfect working order. In case of doubt, contact a dealer.
Make sure the idle speed setting is correct. The saw chain must not run when the engine is idling with the throttle trigger released. Check and cor- rect the idle speed setting at regular intervals. If the saw chain still moves, have your dealer check your machine and make proper adjust- ments or repairs.
The chain saw produces poisonous exhaust gases as soon as the engine starts. These gases may be colour- less and odourless and may contain unburnt hydrocarbons and benzene. Never work with the machine indoors or in poorly ventilated areas, even if your machine is equipped with a cata- lytic converter.
Ensure proper ventilation when working in trenches, hollows or other confined locations ­ risk of fatal injury from breathing toxic fumes!
If you feel sick, have a headache, vision prob- lems (e. g., your field of vision gets smaller),

hearing problems, dizziness or inability to con- centrate, stop work immediately. Such symptoms may be caused by an excessively high concen- tration of exhaust emissions ­ risk of accident!
2.11 After finishing work
Switch off the motor, engage the chain brake and attach the chain scabbard.
2.12 Storage
When the machine is not in use, it should be stored in such a way that no-one is endangered. Secure the machine against unauthorised use.
Store the machine in a safe, dry room.
2.13 Loss-proof chain scabbard
The loss-proof chain scabbard is designed espe- cially for using the chain saw in a tree.

Always use the pull-out ring (4) on the back of the chain saw to transport and secure the chain saw on a rope.
Never use one of the chain scabbard rings (1) to transport or secure the chain saw ­ risk of acci- dent due to falling chain saw!
2.14 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 cir-
culation (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
7

English
any of the above symptoms appear (e.g. tingling sensation in fingers), seek medical advice.
2.15 Maintenance and repairs
Always switch off the engine before any repair, cleaning or maintenance work and any work on the chain. Risk of injury if the engine starts inad- vertently!
The machine must be serviced regularly. Do not attempt any maintenance or repair work not described in the Instruction Manual. All other work should be carried out by a servicing dealer.
STIHL recommends that maintenance and repair work be carried out only by authorised STIHL dealers. STIHL dealers receive regular training and are supplied with technical information.
Use only high-quality spare parts. Otherwise, there may be a risk of accidents and damage to the machine. If you have any questions in this respect, consult a servicing dealer.
Do not modify the machine in any way ­ this may increase the risk of personal injury ­risk of acci- dents!
To reduce the risk of fire due to ignition outside the cylinder, move the master control level to STOP, 0 or before turning the engine over on the starter when the spark plug boot is removed or the spark plug is unscrewed!
Do not service or store the machine near a naked flame ­ risk of fire due to the fuel!
Check fuel cap regularly for tightness.
Use only spark plugs that are in perfect condition and have been approved by STIHL ­ see “Speci- fications”.
Check ignition lead (insulation in good condition, secure connection).
Check that the muffler is in perfect working con- dition.
Do not use the machine if the muffler is damaged or missing ­ risk of fire, damage to hearing!
Never touch a hot muffler ­ risk of burns!
The condition of the anti-vibration elements influ- ences vibration behaviour ­ inspect anti-vibration elements periodically.
Inspect chain catcher ­ replace if damaged.
Switch off the engine ­ To check the chain tension ­ To retension the chain

3 Reactive Forces ­ To replace the chain ­ For remedying malfunctions Observe sharpening instructions ­ for safe and proper handling, always keep the chain and guide bar in flawless condition. Keep the chain properly sharpened, tensioned and well lubrica- ted. Change chain, guide bar and chain sprocket in due time. Regularly check that the clutch drum is in perfect working condition. Always store fuel and chain lubricant only in the specified type of containers and ensure they are correctly labelled. Store in a dry, cool and secure place protected against light and sunlight. In the event of a chain brake malfunction, switch off the machine immediately ­ risk of injury! Con- sult a servicing dealer ­ do not use the machine until the malfunction has been remedied, see “Chain brake”.
3 Reactive Forces
The most common reactive forces that occur dur- ing cutting are: kickback, pushback and pull-in.
3.1 Dangers of kickback
Kickback can result in serious or fatal injury.
(Kickback) occurs when the saw is suddenly thrown up and back in an uncontrolled arc towards the operator.

0012BA022 KN

0458-599-0121-D

4 Working Techniques
3.2 Kickback occurs if, e. g.,

3.5 Pull-in (A)

English

001BA037 KN

001BA257 KN

A

­ when the upper quadrant of the bar nose unin- tentionally contacts wood or another solid object, e.g. when another limb is touched acci- dentally during limbing.
­ when the chain at the nose of the guide bar is pinched in the cut.
3.3 Quickstop chain brake:
This device reduces the risk of injury in certain situations ­ it cannot prevent kickback. When activated, the chain brake stops the saw chain within a fraction of a second ­ see the section “Saw chain” in this Instruction Manual.
3.4 To reduce the risk of kickback
­ Work cautiously and avoid situations which could cause kickback.
­ Hold the saw firmly with both hands and main- tain a secure grip.
­ always cut at full throttle. ­ Be aware of the location of the guide bar nose
at all times. ­ do not cut with the bar nose. ­ Take special care with small, tough limbs, they
may catch the chain. ­ never cut several limbs at once. ­ do not overreach. ­ never cut above shoulder height. ­ Use extreme caution when re-entering a previ-
ous cut. ­ Do not attempt plunge cuts if you are not
experience in this cutting technique. ­ be alert for shifting of the log or other forces
that may cause the cut to close and pinch the chain. ­ always cut with a correctly sharpened, prop- erly tensioned chain ­ the depth gauge setting must not be too large. ­ Use a low kickback chain and a narrow radius guide bar.
0458-599-0121-D

Pull-in may occur when the chain on the bottom of the bar is suddenly pinched, caught or encounters a foreign object in the wood. The reaction of the chain pulls the saw forward ­ STIHL recommends retrofitting the spiked bumper when working on impervious wood and thus to securely engage the motor saw.
3.6 Pushback (B)
B
Pushback occurs when the chain on the top of the bar is suddenly pinched, caught or encoun- ters a foreign object in the wood. The reaction of the chain drives the saw straight back toward the operator ­ to avoid this risk: ­ Be alert to situations that may cause the top of
the guide bar to be pinched ­ Do not twist the guide bar in the cut
4 Working Techniques
4.1 Sawing
Do not operate your saw in the starting throttle position. Engine speed cannot be controlled with the throttle trigger in this position. Work calmly and carefully ­ in daylight conditions and only when visibility is good. Ensure you do not endanger others ­ stay alert at all times. Use the shortest possible guide bar: The chain, guide bar and chain sprocket must match each other and your saw.
9

001BA038 KN

English
Position the saw so that your body is clear of the cutting attachment.
If conditions allow, work from a lift bucket. Never work on a ladder or on any other insecure support, do not work above shoulder height. Cordon off the work area in order to reduce the risk of injuries and damage to bystanders or property (e. g. motor vehicles) from falling branches. When working with a lifeline there is a risk of cut- ting through the rope ­ to reduce the risk of fall injuries,always use double lifelines. Take special care when cutting through a limb. Hold the machine firmly to control and counteract the feed force. At the end of the cut, the chain saw is no longer supported by the cutting attach- ment in the cut. You have to take the full weight of the chainsaw since it might otherwise go out of control! Make sure your saw does not touch any foreign materials: Stones, nails, etc. may be flung off and damage the saw chain. The chain saw may kick back unexpectedly ­ risk of accident! If a rotating saw chain hits a stone or another hard object, sparks may be generated which may ignite easily flammable materials under certain conditions. Also dried-out plants and brushwood are combustible, above all in hot and dry weather. If there is a risk of fire, do not use the chain saw in the vicinity of easily combustible 10

materials, dry plants or scrub. It is mandatory that you ask the responsible forestry office about the current fire hazard.
Caution! To avoid risk of electrocu- tion, take extra precautions when cut- ting near power lines. Have the power switched off before starting cutting work in the immediate vicinity of power lines. Do not underbuck freely hanging limbs because the chain may get pinched and cause kickback and loss of control. Be careful when cutting scrub and young trees. Thin shoots can be scooped up by the chain saw and hurled towards the user. Be careful when cutting splintered wood ­ Risk of injury from ejected pieces of wood! After finishing a cut, activate the chain brake to lock the chain or shut down the engine before moving the saw to another position in the tree. Cutting techniques: Begin cutting with the chain saw at full throttle. Always pull the saw out of the cut with the chain running. ­ Cut straight through thin limbs ­ In case of thick limbs, first perform relieving cut from below (approx. 1/5 of diameter), then buck from above ­ Support and secure heavy branches with ropes. If the saw gets pinched in the cut: ­ Shut off the engine and secure the saw to the tree ­ in direction of trunk. ­ Carefully free the saw from the cut, using another saw if necessary. Limbs under tension:
Always start relieving cut (1) at compression side (A)

5 Cutting Attachment
Then make bucking cut (2) at the tension side (B) into the direction of the log ­ other- wise the chain saw may pinch or kick back
If not otherwise possible, make the bucking cut from the bottom upwards (underbuck) ­ be wary of pushback.
5 Cutting Attachment
A cutting attachment consists of the saw chain, guide bar and chain sprocket.
The cutting attachment that comes standard is designed to exactly match the chain saw.

The engine requires a mixture of gasoline and engine oil.
WARNING
Avoid direct skin contact with fuel and breathing in of gasoline fumes.
9.1 STIHL MotoMix
STIHL recommends using STIHL MotoMix. This pre-blended fuel is free of benzene and lead, is distinguished by a high octane rating, and always provides the proper mixing ratio.
STIHL MotoMix uses STIHL HP Ultra two-stroke engine oil for optimum engine life.
MotoMix is not available in all markets.
9.2 Mixing fuel
NOTICE
Unsuitable fuels or a mixing ratio that deviates from the specification can lead to severe engine damage. The engine, seals, fuel lines and fuel tank may be damaged if low-quality gasoline or engine oil is used.
9.2.1 Gasoline
Use only high-quality gasoline with an octane rat- ing of at least 90 ROC ­ leaded or unleaded.
Gasoline with an alcohol component exceeding 10% can cause impaired engine performance in engines with manually adjustable carburetors and thus should not be used in these engines.
Engines with M-Tronic deliver full engine per- formance using gasoline with an alcohol compo- nent of up to 27% (E27).
9.2.2 Engine oil
If you mix the fuel yourself, use only STIHL twostroke engine oil or another high-performance engine oil classified as JASO FB, JASO FC, JASO FD, ISO-L-EGB, ISO-L-EGC or ISO-LEGD.
STIHL specifies STIHL HP Ultra two-stroke engine oil or an equivalent high- performance engine oil in order to maintain emission limits over the machine’s service life.

9.3 Storing fuel mixture

Store in approved safety fuel canisters only in a dry, cool and secure place protected against light and sunlight.
Fuel mixture deteriorates with age ­ mix only as much as needed for a few weeks. Do not store fuel mixture for longer than 30 days. The fuel mixture can become unusable more quickly if exposed to light, sunlight or low or high tempera- tures.
STIHL MotoMix however can be stored for up to 5 years without any problems. Shake the canister containing the fuel mixture
thoroughly before refueling

WARNING

Pressure may have built up in the canister ­ open it carefully.
The fuel tank and the canister in which fuel mixture is stored should be cleaned thoroughly from time to time

For automatic and reliable lubrication of the chain and guide bar ­ use only an environmen- tally compatible quality chain and bar lubricant. Rapidly biodegradable STIHL BioPlus is recom- mended.
15

0012BA005 KN %$.1

English
NOTICE
Biological chain oil must be resistant to aging (e.g. STIHL BioPlus), since it will otherwise quickly turn to resin. This results in hard deposits that are difficult to remove, especially in the area of the chain drive and chain. It may even cause the oil pump to seize.
The service life of the chain and guide bar depends on the quality of the lubricant. It is therefore essential to use only a specially formu- lated chain lubricant.
WARNING
Do not use waste oil. Renewed contact with waste oil can cause skin cancer. Moreover, waste oil is environmentally harmful.

12 Filling Chain Oil Tank
STIHL recommends use of the STIHL filling sys- tem for chain oil (special accessory). Close the filler cap
There must still be a small amount of chain oil in the oil tank when the fuel tank is empty.
If the oil tank is still partly full, the reason may be a problem in the oil supply system: Check chain lubrication, clean the oil passages, contact your servicing dealer for assistance if necessary. STIHL recommends that maintenance and repair work be carried out only by authorized STIHL dealers.
13 Checking Chain Lubrica- tion

NOTICE Waste oil does not have the necessary lubricat- ing properties and is unsuitable for chain lubrica- tion.
12 Filling Chain Oil Tank
12.1 Preparing the machine
Thoroughly clean the filler cap and the area around it to ensure that no dirt falls into the tank
Always position the machine so that the filler cap is facing upwards
Open the filler cap
12.2 Filling chain oil tank
Refill the chain oil tank every time you refuel Take care not to spill chain oil during refilling and do not overfill the tank.

The saw chain must always spin off a small amount of oil.
NOTICE
Never operate your machine without chain lubri- cation. If the saw chain runs dry, the cutting attachment may very quickly be damaged beyond repair. Before starting work, always check the chain lubrication and oil level in the tank.
Every new saw chain needs a run-in time of 2 to 3 minutes.
After the saw chain has run in, check the tension of the chain and correct if necessary ­ see “Checking the chain tension”.

14.3 Checking Operation of the Chain Brake

Before starting work: Run engine at idle speed, engage the chain brake (push hand guard towards bar nose) and open the throttle wide for no more than 3 seconds ­ the chain must not rotate. The hand guard must be free from dirt and move freely.

14.4 Chain Brake Maintenance

The chain brake is subject to normal wear. It is necessary to have it serviced and maintained regularly by trained personnel. STIHL recom- mends that you have servicing and repair work carried out exclusively by an authorized STIHL servicing dealer. Maintain the following servicing intervals:

Full-time usage: Part-time usage:

every 3 months every 6 months

15 Winter Operation

Remove chain sprocket cover ­ see “Mounting the bar and chain”

0012BA033 KN

0011BA006 KN

Pull the hand guard towards the front handle until there is an audible click ­ the chain brake is disengaged.
NOTICE
Always disengage chain brake before accelerat- ing the engine (except when checking its opera- tion) and before starting cutting work.
High revs with the chain brake engaged (chain locked) will quickly damage the powerhead and chain drive (clutch, chain brake).
The chain brake is also activated by the inertia of the front hand guard if the kickback force of the saw is high enough: The hand guard is acceler- ated toward the bar nose.
The chain brake will operate only if the hand guard has not been modified in any way.

Set shutter to “winter operation” r
In the “winter operation” setting, heated air is drawn in from around the cylinder and mixed with cold air. This prevents air filter and carburetor icing.

back to the run position F. Refit the spark plug ­ see “Spark Plug”. Hold and start your saw as described.
17 Operating Instructions
17.1 During the 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 unnecessarily high loads dur- ing the break-in period. As all moving parts have to bed in during the break- in period, the frictional resistances in the shortblock are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.
17.2 During work
NOTICE
Open the throttle only when the chain brake is off. Running the engine at high revs with the chain brake engaged (chain locked) will quickly damage the engine and chain drive (clutch, chain brake).
17.2.1 Check chain tension frequently
A new saw chain must be retensioned more fre- quently than one that has been in use already for an extended period.
17.2.2 Chain cold
Tension is correct when the chain fits snugly against the underside of the bar but can still be pulled along the bar by hand. Retension if neces- sary ­ see “Tensioning the Saw Chain”.
17.2.3 Chain at operating temperature
The chain stretches and begins to sag. The drive links must not come out of the bar groove on the underside of the bar ­ the chain may otherwise jump off the bar. Retension the chain ­ see “Ten- sioning the Saw Chain”.

NOTICE
The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings.
17.2.4 After a long period of full-throttle oper- ation
After a long period of full-throttle operation, allow engine to run for a while at idle speed so that the heat in the engine can be dissipated by flow of cooling air. This protects engine-mounted com- ponents (ignition, carburetor) from thermal over- load.
17.3 After finishing work
Slacken off the chain if you have retensioned it at operating temperature during work.
NOTICE
Always slacken off the chain again after finishing work. The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings.
17.3.1 Short-term storage Wait for engine to cool down. Keep the machine with a full tank of fuel in a dry place, well away from sources of ignition, until you need it again. 17.3.2 Long-term storage See “Storing the machine”

­ replace after using two saw chains or sooner ­ if the wear marks (arrows) on the sprocket are
deeper than approx. 0.5 mm since this would reduce the life of the chain. You can use a gauge (special accessory) to check the depth of the wear marks.
Using two saw chains in alternation helps pre- serve the chain sprocket.
STIHL recommends use of original STIHL chain sprockets in order to ensure optimal functioning of the chain brake.
Have the chain sprocket replaced by an author- ized dealer. STIHL recommends that mainte- nance and repair work be carried out only by authorised STIHL dealers.
25 Maintaining and Sharpen- ing the Saw Chain
25.1 Sawing effortlessly with a prop- erly sharpened saw chain
A properly sharpened saw chain cuts through wood effortlessly even with very little pushing.
Never use a dull or damaged saw chain ­ this leads to increased physical strain, increased vibration load, unsatisfactory cutting results and increased wear. Clean the saw chain Check the saw chain for cracks and damaged
rivets Replace damaged or worn chain components
and adapt these parts to the remaining parts in terms of shape and level of wear ­ rework accordingly
Carbide-tipped (Duro) saw chains are especially wear-resistant. For an optimal sharpening result, STIHL recommends STIHL servicing dealers.

25 Maintaining and Sharpening the Saw Chain
WARNING Compliance with the angles and dimensions lis- ted below is absolutely necessary. An improperly sharpened saw chain ­ especially depth gauges that are too low ­ can lead to increased kickback tendency of the chain saw ­ risk of injury!
