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.

Always remove the power tool from your
back and put it on the ground before
refueling. Fuel the unit only when it is
standing on the ground.

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.

Check for leakage. To
reduce the risk of serious
of fatal burn injuries, do
not start or run the engine
until leak is fixed.

Screw-type tank cap

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.

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.

– Throttle trigger must move freely

and spring back to the idle position
when released.

– The setting lever must move easily

to STOP or 0

– The blower tubes must be properly

assembled.

– Keep the handles dry and clean –

free from oil and dirt – for safe
control of the power tool.

– 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 the safety devices in any way.
– Check condition of blower housing.
A worn blower housing (cracks, nicks,

chips) may result in an increased risk of
injury from thrown foreign objects. If the
blower housing is damaged, consult
your dealer – STIHL recommends you
contact a STIHL servicing dealer.

To reduce the risk of accidents, do not
operate the unit if it is not properly
assembled and in good condition.

For emergencies: Practice quickly
opening the fastener on the waist belt,
loosening the shoulder straps and
setting down the unit.

Starting the Engine

Start the engine at least 3 meters from
the fueling spot, outdoors only.

Your power tool is designed to be
operated by one person only. Do not
allow other persons in the work area –
even when starting.

Do not drop start the power tool – start
the engine as described in the
instruction manual.

Place the power tool on level ground,
make sure you have secure footing, hold
the power tool securely.

As soon as the engine starts, the air flow
may throw small objects (e.g. stones) in
your direction.

During Operation

In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the setting lever
to STOP or 0.

BR 700

English

0009BA001 KN

To reduce the risk
of personal injury
from thrown
objects, 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).

Do not direct the air blast
towards bystanders or
animals since the air flow
can blow small objects at
great speed – risk of
injury.

When blow-sweeping (in open ground
and gardens), watch out for small
animals to avoid harming them.

Never leave a running machine
unattended.

Take special care in slippery conditions
– damp, snow, ice,
on slopes and uneven ground.

Watch out for obstacles: Be careful of
refuse, tree stumps, roots and ditches
which could cause you to trip or stumble.

Never work on a ladder or any other
insecure support.

Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.

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 accidents, take a
break in good time to avoid tiredness or
exhaustion.

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 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.

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 dust levels are very high, always wear
a suitable respirator.

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.

After finishing work, put the unit down on
a level, non-flammable surface. To
reduce the risk of fire, do not put it down
near easily combustible materials (e.g.
wood chips, bark, dry grass, fuel).

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 Work". 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.

Using the Blower

The unit is carried as a backpack. Hold
and control the blower tube with your
right hand on the control handle.

Walk slowly forwards as you work –
observe the nozzle outlet at all times –
do not walk backwards – risk of
stumbling.

BR 700

English

Always shut off the engine before taking
the unit off your back.

Working Technique

To minimize blowing time, use a rake
and broom to loosen dirt particles before
you start blowing.

Recommended working technique to
minimize air pollution:

– If necessary, dampen the surface to

be cleaned in order to avoid creating
too much dust.

– Do not blow particles in the direction

of bystanders, in particular in the
direction of children, pets, open
windows or freshly washed
vehicles. Take special care in such
situations.

– Remove the blow-swept debris in

rubbish bins – do not blow it onto the
neighbor's land.

Recommended working technique to
minimize noise:

– Operate your power tool at

reasonable times only – not early in
the morning, late at night or during
midday rest periods when people
could be disturbed. Observe local
rest periods.

– Operate blowers at the lowest

engine speed necessary to
accomplish the task.

– Check your blower before starting

work. Pay special attention to the
muffler, air intakes and air filter.

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:

– Keeping your hands warm
– Work breaks

The period of usage is shortened by:
– Any personal tendency to suffer

from poor circulation (symptoms:

frequently cold fingers, itching).

– Low outside temperatures.
– Gripping force (a tight grip hinders

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 since there is otherwise a
risk of fire from uncontained sparking.

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.
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.

Fuel

This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.

Your engine requires a mixture of high­quality premium gasoline and high­quality 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.

10

BR 700

English

452BA123 KN

002BA447 KN

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 air­cooled 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.
