KombiSystem Guide to Using this Manual Safety Precautions and
Working Techniques
In the STIHL KombiSystem a number of
different KombiEngines and KombiTools
can be combined to produce a power
tool. In this instruction manual the
functional unit formed by the
KombiEngine and KombiTool is referred
to as the power tool.
Therefore, the separate instruction
manuals for the KombiEngine and
KombiTool should be used together for
the power tool.
Always read and and make sure you
understand both instruction manuals
before using your power tool for the first
time and keep them in a safe place for
future reference.
Pictograms
All the pictograms attached to the
machine are shown and explained in this
manual.

WARNING
Warning where there is a risk of an
accident or personal injury or serious
damage to property.
NOTICE
Caution where there is a risk of
damaging the machine or its individual
components.
Engineering improvements
STIHL's philosophy is to continually
improve all of its products. For this
reason we may modify the design,
engineering and appearance of our
products periodically.
Therefore, some changes, modifications
and improvements may not be covered
in this manual.
The machine should only be provided or
loaned to people familiar with this model
and its operation. The KombiEngine and
KombiTool user manuals should always
be handed over with the machine.
Use your pole pruner for limbing only
(removing or pruning branches). Saw
wood and wooden objects only.
The machine must not be used for any
other purposes – risk of accidents!
Only use guide bars, saw 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 your dealer.
Use only high quality parts and
accessories. in order to avoid the risk of
accidents and damage to the machine.
Special safety precautions must be observed
when working with the
pole pruner because it
operates at a very high
chain speed, has very
sharp cutters and a long
reach.
Both user manuals (KombiEngine and KombiTool)
must be read through
attentively before using
the unit for the first time
and kept in a safe place
for future reference. Noncompliance with the user
manuals may cause serious or even fatal injury.

See also notes on "Before Starting" in
the user manual of the KombiEngine you
are using.
Holding and guiding the machine
Make sure you always have good
balance and secure footing.
Always hold your power tool firmly with
both hands:
Right hand on control handle, left hand
on the loop handle or handle hose, even
if you are left-handed. Wrap your fingers
and thumbs around the handles.
With the KM 94 R KombiEngine, always
use the handle hose of the KombiTool
as the left handle.
While working
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch/button to 0 or STOP.
This power tool is not
insulated. Keep at least
15 m away from electric
power lines – Danger of
fatal electric shock!
Do not allow other persons within a
radius of 15 m of your own position due
to falling branches and ejected wood
particles – Risk of injury! This distance
must also be maintained in relation to
objects (vehicles, window panes) – risk
of property damage!
Keep the bar nose at least 15 m away
from electric power lines . Electric
current may also arc over from highvoltage cables at greater distance. Have
the power switched off before starting
work in the immediate vicinity of power
lines.
Ensure that the engine idling speed is
correct. The saw chain must not move
when the throttle trigger has been
released.
Check and correct the idle speed setting
at regular intervals. If the saw chain still
rotates, have your dealer check your
machine and make proper adjustments
or repairs – see the user manual of the
KombiEngine.
Take special care in slippery, wet
conditions, in snow and on slopes,
uneven ground, etc. – Risk of slipping!
The gear head becomes
hot during operation. To
reduce the risk of burn
injury, do not touch the
gear housing!
Watch out for obstacles: tree stumps,
roots – risk of tripping or stumbling!
Make sure you always have good
balance and secure footing.
When working at heights:
– Always use a lift bucket
– Never use the machine while
standing on a ladder or in a tree
– Never work on an insecure support
– Never use the machine with just one
hand
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 feeling fatigue – risk of accidents!

Work calmly and carefully – in daylight
conditions and only when visibility is
good. Proceed with caution, do not put
others in danger.
Dust (e. g., sawdust), fumes and smoke
produced while using the machine may
be hazardous to health. If dust levels are
high, wear a suitable respirator.
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.
Opening the throttle while the saw chain
is blocked increases the load and
reduces engine speed. The clutch then
slips continuously and this causes
overheating and damage to important
components (e.g. clutch, polymer
housing components) – and this can
increase the risk of injury from the saw
chain moving while the engine is idling.
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". Make sure the safety
devices are working properly. Never use
a power tool that is no longer safe to
operate. In case of doubt, contact a
dealer.
To reduce the risk of injury, switch off the
engine before changing the saw chain.
If you use a harness, ensure that the
exhaust gas flow is diverted away from
your body – Risk of fire!
Limbing
Hold the power tool 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 sawing branches, establish an
escape route and remove all obstacles.
0000003462_002
When performing the separating cut,
position the bar against the branch near
the hook. This will prevent the power tool
from making jolting movements when
you start the separating cut.
Start the cut with the saw chain at full
throttle.
Always cut with a correctly sharpened,
properly tensioned saw chain – the
depth gauge setting must not be too
large.
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".
Exercise extreme caution when sawing
branches under tension – Risk of injury!
Always make a relieving cut on the
compression side first and then perform
the bucking cut at the tension side.
Be careful when cutting splintered wood
– Risk of injury from ejected pieces of
wood!
If working on a slope, always stand uphill
or to the side of the branch which is to be
sawn. Watch out for rolling branches.
HT-KM

English
Note when reaching the end of a cut that
the power tool is no longer supported by
the guide bar in the cut. The user must
bear the weight of the machine – risk of
loss of control!
Always pull the power tool out of the cut
with the saw chain running.
Use the power tool for limbing and
pruning only, not for felling – Risk of
accidents!
Keep the saw chain away from any
foreign objects: Stones, nails, etc. may
be ejected and damage the saw chain.
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 your pole pruner near
easily flammable materials, dry plants or
scrub. It is mandatory that you ask the
responsible forestry office about the
current fire hazard.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the KombiTool and
KombiEngine instruction manuals. 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,always shut
off the enginebefore carrying out any
maintenance or repairs or cleaning the
machine. – Exception: Carburetor and
idle speed adjustments.
Stopping 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 saw. The chain must be
properly sharpened, tensioned and well
lubricated.
Always change the chain, guide bar and
sprocket in good time.
Store chain lubricant in properly
labelled, safety-type canisters only.

the branch. To do this, position the
cutting attachment and guide it
down to the bar nose in an arc.
N Perform the cross-cut (2) – position
the bar with the hook against the
branch and then perform the crosscut
0000003462_003
Flush-cutting thick branches
If the branch diameter is more than
10 cm (4 in), first
N perform the 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
To avoid pinching the bar in the cut,
position the cutting attachment with the
hook against the branch and then
perform the cross-cut from the top

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.
NOTICE
Waste oil does not have the necessary
lubricating properties and is unsuitable
for chain lubrication.

Operating Instructions Taking Care of the Guide Bar
During Operation
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 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 for a long period
See chapter on "Storing the Machine"

N Turn the bar over – every time you
sharpen the chain and every time
you replace the chain – this helps
avoid one-sided wear, especially at
the nose and underside of the bar

Storing the Machine Checking and Replacing the
Chain Sprocket
For periods of 30 days or longer
N Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
N If you use a biological chain and bar
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
N If the KombiTool is removed from
the KombiEngine and stored
separately: Fit the protective cap on
the drive tube to avoid dirt getting
into the coupling.
N Store the machine in a dry, high or
locked location – out of the reach of
children and other unauthorized
persons.
N Remove chain sprocket cover, saw
chain and guide bar
Replace the chain sprocket
– replace 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
service life of the saw chain. You
can use a gauge (special
accessory) to check the depth of the
wear marks
Using two saw chains in alternation
helps preserve the chain sprocket.
STIHL recommends the use of original
STIHL chain sprockets.

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
0000097198_001
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
inch mm
7 1/4 P 6,35
1 or 1/4 1/4 6,35
6, P or PM 3/8 P 9,32
2 or 325 0.325 8,25
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.
Filing and side plate angles

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.
Cutter shapes Angle (°)

63 PS3, 26 RS, 36 RS3
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.

between depth gauge and cutting
edge.
This setting may be increased by 0.2

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.

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.
