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.).
0458-599-0121-D

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.
0012BA024 KN
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.
4
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),
0458-599-0121-D

2 Safety Precautions
English
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 one of the two rings to fasten the chain scabbard to the harness
for storage while working.

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)
0458-599-0121-D

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.

11 Chain Lubricant
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”.

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

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!

With varying cutter lengths, the cutter heights also vary and cause rough
running of the saw chain and chain breakage. All cutters must be filed down
equal to the
length of the shortest cutter ideally, one should have this done by a
servicing dealer using an electric sharpener

25 Maintaining and Sharpening the Saw Chain
Lay the appropriate file gauge (1) for the chain pitch on the saw chain and
press it against the cutter to be checked if the depth gauge pro- trudes
past the file gauge, the depth gauge must be reworked
Saw chains with humped drive link (2) upper part of the humped drive link
(2) (with service mark) is lowered at the same time as the depth gauge of the
cutter.
WARNING
The rest of the humped drive link must not be filed; otherwise, this could
increase the tendency of the chain saw to kick back.

The depth gauge determines the depth to which the cutter penetrates the wood
and thus the chip thickness.
a Required distance between depth gauge and cutting edge
When cutting softwood outside of the frost sea- son, the distance can be increased by up to 0.2 mm (0.008″).
