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.
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.
Screw-type fuel cap
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.
– Check condition of harness straps
and backpack – replace damaged
or worn straps.
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 your power tool 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.
Gasoline is an extremely
flammable fuel. Keep
clear of naked flames. Do
not spill any fuel – do not
smoke.
Check for leakage. To
reduce the risk of serious
of fatal burn injuries, do
not start or run the engine
until leak is fixed.
After fueling, tighten
down the screw-type fuel
cap as securely as
possible.
BR 700

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.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
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.
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 machine 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.
To reduce the risk
of injury from
thrown objects, do
not allow any other
persons within 15
meters of your
own position.
Do not direct the air blast
towards bystanders or
animals since the air flow
can blow small objects at
great speed.
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.

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.
