It must not be used for any other
purpose because of the increased risk of
accidents and damage to the machine.
Guide to Using this Manual Safety Precautions and
Working Techniques
Special safety precau-
tions must be observed
when working with this
power tool because of its
high torque and the high
speed of the auger in cer-
tain applications, and
because the augers have
sharp edges.
It is important you read
and understand the
instruction manual before
first use and keep the
manual in a safe place for
future reference. Non-
observance of the
instruction manual may
result in serious or even
fatal injury.

Before drilling, make sure there are no
buried power cables or supply pipes in
the work area (e.g. for gas, water,
electricity):
–Contact your local utility company
for information on cable and pipe
locations.
–Where necessary, confirm actual
location with cable detectors and/or
by carefully dug trenches.
Only use drilling tools and accessories
that are explicity approved for this power
tool by STIHL or are technically
identical. If you have any questions in
this respect, consult a servicing dealer.
Use only high quality parts and
accessories in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
Never attempt to modify your unit 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
the power tool. The solid jet of water
may damage parts of the power tool.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Avoid clothing that could get caught on
branches or brush or moving parts of the
machine. Do not wear a scarf, necktie or
jewelry.
Wear steel-toed safety boots with non-
slip soles.
Wear a safety hard hat where there is a
danger of head injuries from falling
objects.
STIHL offers a comprehensive range of
personal protective clothing and
equipment.
Transporting the Power Tool
Always turn off the engine.
The power tool should be carried by two
persons by the handle frame.
Remove the auger before transporting
the power tool long distances. Toreduce
the risk of burn injury, carry the unit by
the handle frame with hot parts of the
machine (e.g. gearbox, muffler) away
from your body.
Allow the unit to cool down before
transporting it by vehicle.
Transporting in a vehicle: Properly
secure your power tool to prevent
turnover, fuel spillage and damage.
Fueling
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 well-
ventilated areas. If you spill fuel, wipe
the machine immediately – if fuel gets on
your clothing, change immediately.
Clothing must be sturdy
but allow complete free-
dom of movement. Wear
snug-fitting clothing, an
overall and jacket combi-
nation, do not wear a
work coat.
Tie up and confine long
hair (e.g. with a hair net,
cap, hard hat, etc.).
Wear safety glasses or
other suitable eye protec-
tion. Wear hearing
protection, e.g. earplugs
or ear muffs.
Wear heavy-duty work
gloves made of durable
material (e.g. leather).
Gasoline is an extremely
flammable fuel. Keep
clear of naked flames. Do
not spill any fuel – do not
smoke.
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.

BT 360

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
Unfold the handle frame and make sure
it is properly locked in the working
position – see "Assembling the
Machine".
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.
–Stop switch on powerhead must
move easily to STOP and stop
switch on handlebar must move
easily to 0.
–Smooth action of throttle lever – it
must return automatically to idle
position.
–Throttle cable properly positioned –
see "Assembling the Machine",
"Fitting the Throttle Cable".
–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.
–Check that handle hoses on
handlebars and coating on throttle
lever are in good condition.
To reduce the risk of personal injury, do
not operate your power tool if it is
damaged or not properly assembled.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Do not start the engine with the auger in
the spindle. The machine must be
operated by 2 persons and may be
started only when it is held steady by the
operating crew.
Do not allow other persons in the work
area – even when starting.
Start the engine as described in the
instruction manual.
Note that the drilling spinde continues to
rotate for a short period after you let go
of the throttle trigger (flywheel effect).
To reduce the risk of injury, never use
drilling tools or augers that are longer
than 1 meter.
Place the unit on level ground, make
sure you have secure footing, hold the
unit securely.
Check idle speed setting: The drilling
tool must not rotate when the engine is
idling with the throttle lever released.
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
The machine is operated by two
persons. They must hold the handle
frame firmly with both hands
Make sure you always have good
balance and secure footing.
Wrap your fingers and thumbs around
the handles.

During Operation
Good and clear communications
between the operators reduces the risk
of injury. Instructions and directions may
be given only by the person who is
controlling the throttle lever.
The auger may jam in the hole,
especially when working in rocky ground
or ground with a heavy root structure. In
such a case the power tool may begin to
rotate around the jammed auger – shut
off the engine immediately.
Always keep feed pressure and auger
speed at a level that suits conditions and
clear the hole frequently by lifting the
auger slightly.
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the stop switch
on the powerhead to STOP or the stop
switch on the handlebar to 0.
Note that the drilling spinde continues to
rotate for a short period after you let go
of the throttle trigger (flywheel effect).
Do not touch a hot muffler – operate the
machine only with the muffler guard
securely mounted in position.
Do not allow any other persons in the
work area. To reduce the risk of injury,
keep a sufficiently safe distance away
from other persons.
Make sure that the idle speed is properly
adjusted: The drilling tool must stop
rotating, after a brief delay, when you
release the throttle lever. If the drilling
tool continues to rotate when the engine
is idling, have the machine checked by
your servicing dealer. Check and correct
the idle speed setting regularly.
Take special care in slippery conditions
– damp, snow, ice, on slopes or uneven
ground.
Watch out for obstacles: Roots, tree
stumps or holes which could cause you
to trip or stumble.
Make sure you always have good
balance and secure footing.
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.
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.
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, have the
unit checked by your servicing dealer.
Do not operate your saw with the
starting throttle lock engaged.
When taking the auger out of the hole,
lift the machine vertically so that the tool
comes out straight without canting.
To reduce the risk of
injury, keep work
area around power
tool clear of
obstacles.
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These fumes
may be colorless and
odorless and contain
unburned hydrocarbons
and benzol. Never run
the engine indoors or in
poorly ventilated loca-
tions, even if your model
is equipped with a cata-
lytic converter.

To reduce the risk of injury, do not touch
the auger or drilling spindle unless the
engine is stopped and the auger is at a
standstill.
Hold the machine firmly in order to
control sudden jolts and reactive forces
– keep feed pressure relatively low.
Cover and clearly mark boreholes.
To reduce the risk of injury, shut off the
engine before changing the auger.
To avoid serious burn injuries, avoid
touching hot parts of the machine,
especially the muffler.
Before leaving the power tool
unattended: Shut off the engine.
Check condition of augers regularly.
Replace damaged or dull augers
immediately.
The power tool is designed to produce
the best results when the vibrations felt
by the user are lowest. If you notice an
increase in vibrations while you are
working, reduce speed on the throttle
lever to achieve greater drilling
efficiency.
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 unit. If you have any
questions in this respect, consult a
servicing dealer.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury,always shut
off the engine before carrying out any
maintenance or repairs or cleaning the
machine. – Exception: Carburetor and
idle speed adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed unless the stop switch on
the powerhead is on STOP or the stop
switch on the handlebar is on 0 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.
Avoid contact with electri-
cal cables or wires – risk
of electric shock.
Work particularly care-
fully in rocky ground or
ground with a heavy root
structure.

Your engine requires a mixture of
gasoline and engine oil.
WARNING
For health reasons, avoid direct skin
contact with gasoline and avoid inhaling
gasoline vapor.
STIHL MotoMix
STIHL recommends the use of STIHL
MotoMix. This ready-to-use fuel mix
contains no benzol or lead, has a high
octane rating and ensures that you
always use the right mix ratio.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil for an extra long
engine life.
MotoMix is not available in all markets.
Mixing Fuel
NOTICE
Unsuitable fuels or lubricants or mix
ratios other than those specified may
result in serious damage to the engine.
Poor quality gasoline or engine oil may
damage the engine, sealing rings, hoses
and the fuel tank.
Gasoline
Use only high-quality brand-name
gasoline with a minimum octane rating
of 90 – leaded or unleaded.
If your machine is equipped with a
catalytic converter, you must use
unleaded gasoline.
NOTICE
A few tankfuls of leaded gasoline will
greatly reduce the efficiency of the
catalytic converter.
Gasoline with an ethanol content of
more than 10% can cause running
problems in engines with a manually
adjustable carburetor and should not be
used in such engines.
Engines equipped with M-Tronic deliver
full power when run on gasoline with an
ethanol content of up to 25% (E25).
Engine oil
Use only high-quality two-stroke engine
oil – preferably STIHL HP, HP Super or
HP Ultra, which are specially formulated
for use in STIHL engines. HP Ultra
guarantees high performance and a
long engine life.
These engine oils are not available in all
markets.
Use only STIHL 50:1 two-stroke engine
oil for the fuel mix in models with a
catalytic converter.
Mix Ratio
STIHL 50:1 two-stroke engine oil: 50
parts gasoline to 1 part oil
Examples
NUse a canister approved for storing
fuel. Pour oil into canister first, then
add gasoline and mix thoroughly.
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.
NThoroughly shake the mixture in the
canister before fueling your
machine.
WARNING
Pressure may build up in the canister –
open it carefully.

so that its tip pierces the ground and
stays upright.
NWith the engine running at idle
speed, position the powerhead on
the upright auger bit. Make sure the
end of the auger properly engages
the drilling spindle's coupling.
NLock the auger in the drilling spindle
by rotating the clamp ring (1) one
quarter turn counterclockwise.
During break-in period
A factory-new machine should not be
run at high revs (full throttle off load) for
the first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
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. For longer out-of-service periods
– see "Storing the Machine".
Working with shaft extension (special
accessory)
Do not fit the shaft extension until the full
length of the auger is in the hole.
WARNING
Starting a hole with the shaft extension
fitted increases the risk of personal
injury because the unit is then at chest
height and cannot be controlled
properly. For the same reason the shaft
extension must be removed before the
auger is pulled out of the hole.
Inspection by a specialist
If the machine is used commercially, it
must be inspected at least once a year
by a specialist.
Specialists are persons with the
technical training and experience
necessary to assess the safe working
condition of the earth auger.

If it is dirty or damaged:
NUnscrew the end cover (5) with
wingnut.
NRemove and replace the main filter.
Always install a new auxiliary filter
together with the new main filter.
NInspect the auxiliary filter (6) – if it is
dirty, knock it out on the palm of
your hand – if it is damaged, install a
new one.
When removing the auxiliary filter take
care to ensure that no dirt falls into the
intake.
NClean the filter box – reassemble all
filter components.
NRefit the filter cover.
NTighten down the screw.

General Information
This setting provides an optimum fuel-air
mixture under most operating
conditions.
Readjust idle
Engine stops while idling
NTurn the idle speed screw (LA)
clockwise until the drilling spindle
begins to rotate – then back it off 1/2
a turn.
Drilling spindle rotates when engine is
idling
NTurn the idle speed screw (LA)
counterclockwise until the drilling
spindle stops rotating – then turn it
another 1/2 turn in the same
direction.
NIf the engine is down on power,
difficult to start or runs poorly at idle
speed, first check the spark plug.
NFit a new spark plug after about 100
operating hours – or sooner if the
electrodes are badly eroded. Install
only suppressed spark plugs of the
type approved by STIHL – see
"Specifications".
Removing the Spark Plug
NMove the stop switch on the
powerhead to STOP.
NMove the stop switch on the
handlebar to 0.
NPull boot off the spark plug.
NUnscrew the spark plug.
Checking the spark plug
NClean dirty spark plug.
NCheck electrode gap (A) and
readjust if necessary – see
"Specifications".
NRectify the problems which have
caused fouling of the spark plug.
Possible causes are:
–Too much oil in fuel mix.
–Dirty air filter.
–Unfavorable running conditions.
WARNING
If the spark plug comes with a
detachable adapter nut (1), screw the
adapter onto the thread and tighten it
down firmly to reduce the risk of arcing
and fire.

Installing the Spark Plug
NScrew the spark plug (3) into the
cylinder and fit the boot (2) (press it
down firmly).
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor is properly
adjusted, the cause may be the muffler.
Have the muffler checked for
contamination (carbonization) by your
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
Use a mildly alloyed gear oil (see
"Special Accessories") for lubrication of
the gearbox.
Checking Oil Level / Refilling
NCheck the oil level regularly – once
a week in normal operating
conditions.
NRemove the auger.
NPosition the gearbox vertically so
that the drilling spindle is horizontal
and the throttle trigger is at the top.
NTake out the inspection plug (1).
NCheck the oil level – it must come up
to the bottom edge of the hole.
If the oil level does not reach the bottom
edge of the hole, top up with oil.
NTake out the filler plug (2).
NFill up with oil as far as the bottom
edge of the inspection hole.
NRefit the inspection and filler plugs
with sealing rings and tighten them
