Safety Precautions and
Working Techniques
Special safety precautions must be observed
when working with the
pole pruner because it is
a high-speed, fast-cutting power tool with very
sharp cutters and a long
reach.
It is important that you
read the instruction manual 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.

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.
Use your pole pruner for limbing only
(removing or pruning branches). Only
cut wood or wooden objects.
Do not use your power tool for any other
purpose because of the increased risk of
accidents.
Only use guide bars, chains, chain
sprockets 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, guide bars, chains, chain
sprockets and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
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 freedom of movement. Wear
snug-fitting clothing, an
overall and jacket combination, 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.).
Wear steel-toed safety
boots with non-slip soles
and cut-retardant inserts.
WARNING
To reduce the risk of eye
injuries, wear close-fitting safety glasses in
accordance with European Standard EN 166.
Make sure the safety
glasses are a comfortable and snug fit.
Wear hearing protection, e.g. earplugs
or ear muffs.
Wear a safety hard hat with chin strap
where there is a danger of head injuries
from falling objects.
Wear heavy-duty work
gloves made of durable
material (e.g. leather).
STIHL offers a comprehensive range of
personal protective clothing and
equipment.
Transporting the Power Tool
Always shut off the engine.
Always fit the chain guard (scabbard) –
even when you carry the unit for short
distances.
HT 102, HT 103, HT 132, HT 133
3
English
Carry the power tool properly balanced
by the drive tube. To avoid serious burn
injuries, avoid touching hot parts of the
machine, especially the surface of the
muffler.
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.
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.
After fueling, tighten
down the screw-type fuel
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.
– Correctly mounted guide bar
– Correctly tensioned chain
– The stop switch 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 knob must
spring back from the g and <
positions 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.
– 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 the harness to suit your
height and reach. See chapter on
"Fitting the Harness".
To reduce the risk of accidents, do not
operate your power tool if it is damaged
or not properly assembled.
If you use a shoulder strap or full
harness: Practice removing and putting
down the machine as you would in an
emergency. To avoid damage, do not
throw the machine to the ground when
practicing.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The chain must be clear of the
ground and all other obstructions
because it may begin to run when the
engine starts.
Your power tool is designed to be
operated by one person only. To reduce
the risk of injury, do not allow other
persons within 15 meters of your own
position – even when starting.
Start the engine as described in the
instruction manual.
Note that the chain continues to run for a
short period after you let go of the
throttle trigger (flywheel effect).
Check idle speed setting: The chain
must not move when the engine is idling
with the throttle trigger released.

15m (50ft)
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
Always hold the unit firmly with both
hands – right hand on the control handle,
left hand on the drive tube – even if you
are left-handed. Wrap your fingers
around the control handle and drive
tube.
Machines with telescoping shaft: Only
extend the telescoping shaft as far as
necessary for the cutting work that
needs to be done.
During Operation
Make sure you always have good
balance and secure footing.
In the event of imminent danger or in an
emergency, switch off the engine
immediately – operate the stop switch.
This power tool is not
insulated against electric
shock. To reduce the risk
of electrocution maintain
a minimum clearance of
15 m from electric power
lines.
To reduce the risk of injury from falling
objects and thrown pieces of wood, 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).
Maintain a minimum clearance of 15 m
between the bar nose and electric power
lines. Electricity can jump considerable
distances by means of arcing. Higher
voltage increases the distance electricity
can arc. Have the power switched off
before starting cutting work in the
immediate vicinity of power lines.
To reduce the risk of injury, shut off the
engine before changing the saw chain.
Make sure the idle speed setting is
correct. The chain must not run when
the engine is idling with the throttle
trigger released.
It the chain still rotates, have your dealer
make proper adjustments or repairs.
Check and correct the idle speed setting
regularly.
Never leave a running power tool
unattended.
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.
When working at heights:
– Always use a lift bucket
– Never work on a ladder or in a tree
– Never work on an insecure support
– 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 locations, even if your model
is equipped with a catalytic converter.
To reduce the risk of serious or fatal
injury from breathing toxic fumes,
ensure proper ventilation when working
in trenches, hollows or other confined
locations.
To reduce the risk of accidents, stop
work immediately in the event of
nausea, headache, visual disturbances
(e.g. reduced field of vision), problems
with hearing, dizziness, deterioration in
ability to concentrate. Apart from other
possibilities, these symptoms may be
caused by an excessively high
concentration of exhaust gases in the
work area.
Operate your power tool so that it
produces a minimum of noise and
emissions – do not run the engine
unnecessarily, accelerate the engine
only 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 (e.g. sawdust), vapor and
smoke produced during operation may
be dangerous to health. If dust levels are
very high, wear a suitable 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.
If you use a shoulder strap, make sure
exhaust gases are diverted away from
your body since there is otherwise a risk
of fire.
Limbing
Hold the pole pruner at an angle. Do not
stand directly underneath the limb being
cut. Do not exceed an angle of 60° from
the horizontal. Watch for falling wood.
Keep the work area clear – remove
interfering limbs and brush.
Before limbing, establish a path of
escape and remove all obstacles.
Position the cutting attachment with the
hook against the branch and then
perform the cross-cut. This reduces the
risk of the pruner being jerked forward
as you start the cross-cut.
Always start the cut with the engine at
full throttle.
Always cut with a correctly sharpened,
properly tensioned chain – the depth
gauge setting must not be too large.
Do not operate your power tool in the
starting throttle position – engine speed
cannot be controlled in this position.
Perform cross-cut from the top
downward to avoid the chain pinching in
the cut.
If branch is thick or heavy, make a
relieving cut – see chapter on "Using the
Pole Pruner".
To reduce the risk of injury, take special
care when cutting branches under
tension.
Always make a relieving cut on
the compression side first and then
perform the bucking cut at the tension
side.
6
HT 102, HT 103, HT 132, HT 133
English
To reduce the risk of injury, take special
care when cutting shattered wood
because of the risk of injury from slivers
being caught and thrown in your
direction.
If on a slope, stand on the uphill side or
to one side of the branch to be cut.
Watch out for rolling branches.
Note when reaching the end of a cut that
the unit is no longer supported by the
guide bar in the cut. You have to take the
full weight of the machine since it might
otherwise go out of control.
Always pull the unit out of the cut with
the chain running.
To reduce the risk of accidents, use your
pole pruner for limbing and pruning only.
It is not designed for felling.
Make sure your saw chain does not
touch any foreign materials: Stones,
nails, etc. may be flung off and damage
the saw chain.
If the rotating chain 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 your pole pruner near combustible
materials, dry plants or scrub. Always
contact your local forest authority for
information on a possible fire risk.
Before leaving the power tool
unattended: Shut off the engine.
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 genuine
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.
HT 102, HT 103, HT 132, HT 133

English
246BA030 KN
To reduce the risk of fire, do not operate
your machine if the muffler is damaged
or missing – there is also a risk of
hearing damage.
Do not touch a hot muffler since burn
injury will result.
Shut off the engine
– before checking chain tension.
– before retensioning the chain.
– before replacing the chain.
– before rectifying problems.
Observe sharpening instructions – keep
the chain and guide bar in good
condition at all times for safe and correct
handling of the machine. The chain must
be properly sharpened, tensioned and
well lubricated.
Always change the chain, guide bar and
sprocket in good time.
Store fuel and chain lubricant in properly
labeled, safety-type canisters only.
When handling gasoline, avoid direct
contact with the skin and avoid inhaling
fuel vapor – health risk.
Using the Unit
Preparations
N Wear suitable protective clothing,
observe safety precautions.
N Adjust telescoping shaft to the
required length (HT 103, HT 133
only).
N Start the engine.
N Put on the shoulder strap.
Cutting Sequence
To allow branches to free fall, always cut
the lower branches first. Prune heavy
branches (large diameter) in several
controllable pieces.
WARNING
Never stand directly underneath the
branch you are cutting – be wary of
falling branches. Note that a branch may
spring back at you after it hits the ground
– risk of injury.
HT 102, HT 132
Always hold the shaft with your left hand
in the area of the handle hose.
The shaft should always be held at an
angle of 60° or less.
The least tiring working position is a tool
angle of 60°.
Any lesser angle may be used to suit the
situation.
Disposal
Do not throw cuttings into the garbage
can – they can be composted.
Working Techniques
Hold the control handle with your right
hand, and the shaft with your left hand.
Your left arm should be extended to the
most comfortable position.

Cross-cut
To avoid pinching the bar in the cut,
position the cutting attachment with the
housing against the branch and then
perform the cross-cut from the top
downwards.
Relieving cut
N To do this, apply the cutting
attachment and pull it across the
bottom of the branch in an arc as far
as the bar nose.
N Perform the cross cut (2) – position
the bar with the housing against the
branch.
Flush-cutting thick branches
Cutting above obstacles
The machine's long reach makes it
possible to prune branches that are
overhanging obstacles, such as rivers or
lakes. The tool angle in this case
depends on the position of the branch.
Cutting from a lift bucket
To avoid tearing the bark on thick
branches, always start by performing a
relieving cut (1) on the underside of the
branch.
HT 102, HT 103, HT 132, HT 133
If branch diameter is more than
10 cm (4 in), first
N perform undercut (3) and then
cross-cut at a distance of about
20 cm/8 in (A) from the final cut.
Then carry out the flush-cut (4),
starting with a relieving cut and
finishing with a cross-cut.
The machine's long reach enables
cutting to be performed next to the trunk
without the risk of the lift bucket
damaging other branches. The tool
angle in this case depends on the
position of the branch.

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 pole pruner.
– The pitch (t) of the saw chain (1),
chain sprocket and the nose
sprocket of the Rollomatic guide bar
must match.
– The drive link gauge (2) of the saw
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
Chain Scabbard
The scope of supply includes a bar
scabbard that matches the cutting
attachment.
If guide bars of different lengths are
mounted to the pole pruner, always use
a chain scabbard of the correct length
which covers the complete guide bar.
The length of the matching guide bars is
marked on the side of the chain
scabbard.

Storing Fuel
Store fuel only in approved safety-type
fuel canisters in a dry, cool and safe
location protected from light and the sun.
Fuel mix ages – only mix sufficient fuel
for a few weeks work. Do not store fuel
mix for longer than 30 days. Exposure to
light, the sun, low or high temperatures
can quickly make the fuel mix unusable.
STIHL MotoMix may be stored for up to
2 years without any problems.
N Thoroughly shake the mixture in the
canister before fueling your
machine.
WARNING
Pressure may build up in the canister –
open it carefully.
N Clean the fuel tank and canister
from time to time.
Dispose of remaining fuel and cleaning
fluid properly in accordance with local
regulations and environmental
requirements.

Fueling
Preparations
N Before fueling, clean the filler cap
and the area around it to ensure that
no dirt falls into the tank.
N Position the machine so that the
tank cap faces up.
Opening the Tank Cap
Filling Up with Fuel
Take care not to spill fuel while fueling
and do not overfill the tank.
STIHL recommends you use the STIHL
filler nozzle for fuel (special accessory).
N Fill up with fuel.
Closing the Tank Cap
N Place the cap in the opening.
N Turn the cap clockwise as far as
stop and tighten it down as firmly as
possible by hand.
Chain Lubricant
For automatic and reliable lubrication of
the chain and guide bar – use only an
environmentally compatible quality
chain and bar lubricant. Rapidly
biodegradable STIHL BioPlus is
recommended.
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 formulated chain
lubricant.
WARNING
Do not use waste oil. Renewed contact
with waste oil can cause skin cancer.
Moreover, waste oil is environmentally
harmful.
N Turn the cap counterclockwise until
it can be removed from the tank
opening.
N Remove the tank cap.
14
NOTICE
Waste oil does not have the necessary
lubricating properties and is unsuitable
for chain lubrication.

Checking Chain Lubrication
The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate your machine without
chain lubrication. If the chain runs dry,
the whole cutting attachment will be
irretrievably damaged within a very short
time. Always check chain lubrication and
the oil level in the tank before starting
work.
Every new chain has to be broken in for
about 2 to 3 minutes.
After breaking in the chain, check chain
tension and adjust if necessary – see
"Checking Chain Tension".

Maintaining and Sharpening
the Saw Chain
Cutting effortlessly with a correctly
sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
N Clean the chain.
N Check the chain for cracks in the
links and damaged rivets.
N Replace any damaged or worn
parts of the chain and match the
new parts to the shape and size of
the original parts.
Carbide-tipped saw chains (Duro) are
particularly wear resistant. STIHL
recommends you have your chain
resharpened by a STIHL servicing
dealer.
WARNING
It is absolutely essential to comply with
the angles and dimensions specified
below. If the saw chain is incorrectly
sharpened – and in particular if the depth
gauge is set too low – there is an
increased risk of kickback, with resulting
risk of injury.
The saw chain cannot be locked in place
on the guide bar. Therefore, it is best to
remove the chain from the bar and
resharpen it on a workshop sharpening
tool (FG 2, HOS, USG).
Chain pitch
The chain pitch (a) is marked on the
depth gauge end of each cutter.
Mark (a) Chain pitch

3 or 3/8 3/8 9,32
Select file diameter according to chain
pitch – see table “Sharpening Tools”.
You must observe certain angles when
resharpening the chain cutter.

STIHL saw chains are sharpened to a
filing angle of 30°. Exceptions are
ripping chains with a filing angle of 10°.
Ripping chains have an X in their
designations.
B Side plate angle
The correct side plate angle is obtained
automatically if you use the prescribed
file holder and file diameter.

Ripping chain, e.g.
10 75
63 PMX, 36 RMX
The angles must be the same on all
cutters. If the angles are uneven: Chain
will run roughly, not in a straight line,
wear quickly and finally break.
File holder
N Use a file holder
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.
Use only special saw chain sharpening
files. Other files have the wrong shape
and cut.
For checking angles
Use a STlHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal tool for
checking the filing and side plate angles,
depth gauge setting, cutter length and
groove depth. It also cleans the guide
bar groove and oil inlet holes.
File correctly
N Select sharpening tools according
to chain pitch.
N If you use an FG 2, HOS or USG
sharpener: Remove the chain from
the bar and sharpen according to
the instructions supplied with the
tool.
N Clamp the bar in a vise if necessary.
N Sharpen the chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
N Hold the file horizontally (at a right
angle to the side of the guide bar)
and file according to the angles
marked on the file holder. Rest the
file holder on the top plate and depth
gauge.
N Always file from the inside to the
outside of the cutter.
N The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
N Avoid touching the tie straps and
drive links with the file.
N Rotate the file at regular intervals
while filing to avoid one-sided wear.
N Use a piece of hardwood to remove
burrs from the cutting edge.
N Check angles with the filing gauge.
All cutters must be the same length.

If the cutters are not the same length,
they will have different heights. This
makes the chain run roughly and can
cause it to break.
N Find the shortest cutter and then file
all other cutters back to the same
length. It is best to have this work
done by a servicing dealer on an
electric grinder.
Depth gauge setting
The depth gauge determines the height
at which the cutter enters the wood and
thus the thickness of the chip removed.
a Specified distance or setting
between depth gauge and cutting
edge.
This setting may be increased by 0.2
mm (0.008") for cutting softwood in the
mild weather season – no frost.

Lowering depth gauges
The depth gauge setting is reduced
when the chain is sharpened.
N Use a filing gauge to check the
setting every time you sharpen the
chain.
N Place a filing gauge (1) that
matches the chain pitch on the
chain and press it against the cutter
– if the depth gauge projects from
the filing gauge, the depth gauge
has to be lowered.
Saw chains with humped drive link (2) –
upper part of humped drive link (2) (with
service mark) is lowered along with the
depth gauge.
WARNING
The other parts of the humped drive link
must not be filed since this may increase
the kickback tendency of the power tool.
N File down the depth gauge until it is
level with the filing gauge.
N File the top of the depth gauge
parallel to the stamped service
marking (see arrow) – but do not
lower the highest point of the depth
gauge in this process.
WARNING
The kickback tendency of the machine is
increased if the depth gauges are too
low.

thoroughly.
N Before a long out-of-service period,
clean the chain and store it in a welloiled condition.
N Place the filing gauge on the chain –
the highest point of the depth gauge
must be level with the filing gauge.

Operating Instructions
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
NOTICE
Do not make the mixture leaner to
achieve an apparent increase in power –
this could damage the engine – see
"Adjusting the Carburetor".
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove – the chain may otherwise
jump off the bar. Retension the chain –
see "Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
gear shaft and bearings.
After long period of full-throttle operation
Allow 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 engine-mounted components
(ignition, carburetor) from thermal
overload.
After Finishing Work
N Slacken off the chain if you have
retensioned it at operating
temperature during cutting work.
NOTICE
Always slacken off the chain after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the gear shaft and
bearings.
Storing your saw for a short period
Fit the chain scabbard and allow engine
to cool down. To avoid condensation, fill
the fuel tank and keep the machine in a
dry place, well away from sources of
ignition, until you need it again.

you replace the chain – this helps
avoid one-sided wear, especially at
the nose and underside of the bar.
N Regularly clean the oil inlet hole (1),
the oilway (2) and the bar
groove (3).
N Measure the groove depth – with the
scale on the filing gauge (special
accessory) – in the area used most
for cutting.
The drive link tangs will otherwise
scrape along the bottom of the groove –
the cutters and tie straps will not ride on
the bar rails.

– after using two saw chains or
sooner
– if the wear marks (a) on the sprocket
are deeper than approx. 0.5 mm
(0.02 in) since this would reduce the
life of the chain. You can use a
gauge (special accessory) to check
the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL chain sprockets.
English
The chain sprocket is driven via a friction
clutch. Have the chain sprocket replaced
by a servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
