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 that you
read the instruction man-
ual before first use and
keep it in a safe place for
future reference. Non-
observance of the
instruction manual may
result in serious or even
fatal injury.

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 power tool only for drilling
holes in soil and wood – depending on
the drilling tool mounted. Select drilling
axis so that the auger brake lever is
always in a position to be activated by
the operator's thigh.
Do not use your power tool for any other
purpose.
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 tools and
accessories. in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of genuine
STIHL tools and accessories. They are
specifically designed to match the
product 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 unit. The solid jet of water may
damage parts of the unit.
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 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.
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 sturdy shoes with
non-slip soles.
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).

Transporting the Power Tool
Always turn off the engine.
Remove the auger before transporting
the power tool long distances. To reduce
the risk of burn injury, carry the unit by
the handle frame with hot parts of the
machine (e.g. gearbox) away from your
body.
In vehicles: 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.
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
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.
–Slide control / stop switch must
move easily to STOP or 0.
–Auger brake in good working order.
–Smooth action of throttle trigger and
throttle trigger lockout – throttle
trigger must return automatically to
idle position.
–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.
To reduce the risk of accidents, 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.
Place the unit on level ground, make
sure you have secure footing, hold the
unit securely. Check that the drilling tool
is not touching the ground or any other
object since it may begin to rotate when
the engine starts.
Your power tool is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when starting. To reduce the risk of
injury, avoid contact with the drilling tool.
Do not drop start the power tool – start
the engine as described in the
instruction manual.
Check idle speed setting: The drilling
tool must not rotate when the engine is
idling with the throttle trigger 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).
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.
Check for leakage. To
reduce the risk of serious
of fatal burn injuries, do
not start or run the engine
until leak is fixed.

BT 130

Holding and Controlling the Unit
Always hold the power tool firmly with
both hands on the handles.
Make sure you always have good
balance and secure footing – auger
brake lever against your left thigh.
Wrap you fingers and thumbs tightly
around the handles – left hand on the
control handle.
During Operation
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch to 0 or STOP.
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.
The correct engine idle speed is
important to ensure that the drilling tool
stops rotating when you let go of the
throttle trigger. 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
(ice, wet ground, snow), 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.
Ensure proper ventilation when working
in trenches, hollows or other confined
locations. This reduces the risk of
serious or fatal injury from breathing
toxic fumes.
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.
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.
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, consult
your servicing dealer.

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.

BT 130

Do not operate your power tool in the
starting throttle position – engine speed
cannot be controlled in this position.
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 and engage the auger brake
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.
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, 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 slide control /
stop switch is on STOP or 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).
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.

Check the condition of the muffler.
To reduce the risk of fire and damage to
hearing, do not operate your machine if
the muffler is damaged or missing.
Do not touch a hot muffler since burn
injury will result.
Vibration behavior is influenced by the
condition of the AV elements – check the
AV elements at regular intervals.
Maintenance, replacement, or repair of
the emission control devices and
systems may be performed by any
nonroad engine repair establishment or
individual. However, if you make a
warranty claim for a component which
has not been serviced or maintained
properly or if nonapproved replacement
parts were used, STIHL may deny
coverage.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of the instruction
manual.

The correct throttle cable setting is a
prerequisite for the correct operation of
the warm start, idling and full throttle.
Only set the throttle cable when the
machine is fully installed – the control
handle must be in the working position.

The STIHL 4-MIX engine features
mixture lubrication and must be run on a
fuel mixture of gasoline and engine oil.
It operates otherwise on the 4-stroke
principle.
This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your engine requires a mixture of high-
quality premium gasoline and high-
quality two-stroke air-cooled engine oil.
Use premium branded unleaded
gasoline with a minimum octane rating
of 89 (R+M)/2.
Note: Models equipped with a catalytic
converter require unleaded gasoline. A
few tankfuls of leaded gasoline can
reduce the efficiency of the catalytic
converter by more than 50%.
Fuel with a lower octane rating may
result in preignition (causing "pinging")
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of the piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
high-quality fuels!

Fuels with different percentages of
ethanol are being offered. Ethanol can
affect the running behaviour of the
engine and increase the risk of lean
seizure.
Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
with a manually adjustable carburetor
and should not be used in such engines.
Engines equipped with M-Tronic can be
run on gasoline with an ethanol content
of up to 25% (E25).
Use only STIHL two-stroke engine oil or
equivalent high-quality two-stroke air-
cooled engine oils for mixing.
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STIHL engines.
Do not use BIA or TCW (two-stroke
water cooled) mix oils!
Use only STIHL 50:1 heavy-duty engine
oil or an equivalent quality two-stroke
engine oil for the fuel mix in models
equipped with a catalytic converter.
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapour.
The canister should be kept tightly
closed in order to avoid any moisture
getting into the mixture.
The fuel tank and the canister in which
fuel mix is stored should be cleaned
from time to time.
Fuel mix ratio
Only mix sufficient fuel for a few days
work, not to exceed 30 days of storage.
Store in approved safety fuel-canisters
only. When mixing, pour oil into the
canister first, and then add gasoline.
Dispose of empty mixing-oil canisters
only at authorized disposal locations.
Preparing the machine
NBefore fueling, clean the filler cap
and the area around it so that dirt
cannot fall into the tank
NAlways position the machine so that
the filler cap is facing upwards

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 the auger is jammed in the drilling hole
NSwitch off the engine immediately
NSet the slide control to STOP-0
NSet the activating lever to A – the
auger brake is activated
NTurn the whole auger
counterclockwise to the left until the
auger is released again
