English

The user is responsible for avoiding
injury to third parties or damage to their
property.

Do not lend or rent your unit without the
instruction manual. Be sure that anyone
using it understands the information
contained in this manual.

In some countries the operation of noise
emitting power tools is restricted by local
regulations. Observe country-specific
requirements and regulations.

Do not use a pressure washer to clean
the unit. The solid jet of water may
damage parts of the unit.

Accessories and Spare Parts

Only use parts and accessories that are
explicitly 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 unit.

STIHL recommends the use of genuine
STIHL replacement parts. 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.

Physical Condition

To operate the unit 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. To
reduce health risks, STIHL recommends
that persons with pacemakers consult
their physician and the pacemaker
manufacturer before operating this tool.

Do not operate the power tool if you are
under the influence of any substance
(drugs, alcohol) which might impair
vision, dexterity or judgment.

Applications

The blower is designed for blow­sweeping leaves, grass, paper and
similar materials, e.g. in gardens, sports
stadiums, car parks and driveways. It is
also suitable for blow-sweeping forest
paths.

The vacuum shredder is designed for
picking up dry leaves and other
lightweight, loose and non-combustible
materials.

Do not use your po we r tool for any other
purpose because of the increased risk of
accidents.

Do not operate or store your power tool
at temperatures below -10°C – exposure
to low temperatures may damage
machine components.

Personal Protective Equipment

Wear proper protective clothing and
equipment.

Clothing must be sturdy
but allow complete free­dom of movement. Wear
snug-fitting clothing, an
overall and jacket combi­nation, do not wear a
work coat.

Avoid any clothing, scarves, neckties,
jewellery or anything that could get into
the air intake. 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 and
hearing protection, e.g.
earplugs or ear muffs.

Transporting the Unit

Always stop the engine.

Transporting in a vehicle:

– Properly secure your power tool to

prevent turnover, fuel spillage and
damage.

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.

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.

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.

– Stop switch must move easily to 0

– Check that the spark plug boot is

secure – a loose boot may cause
arcing that could ignite combustible
fumes and cause a fire.

– Check condition of blower wheel

and blower housing – see chapter
on "Using the Unit".

– A worn blower housing (cracks,

nicks, chips) may result in an
increased risk of injury from thrown
foreign objects.

– If either the blower wheel or blower

housing is damaged, consult your
dealer – STIHL recommends you
contact a STIHL servicing dealer.

– Never attempt to modify the controls

or safety devices in any way.

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

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.

Holding and Controlling the Unit

Always hold the power tool firmly in your
hand.

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

During Operation

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

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

To reduce the risk
of injury from
thrown objects, do
not allow any other
persons within a
radius of 5 meters
of your own
position.

Never leave a running machine
unattended.

Take special care in slippery conditions,
on slopes or uneven ground.

Watch out for obstacles such as 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.

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.

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

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).

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.

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.

The dust that occurs during operation
may be harmful 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 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 Vacuum Attachment

For specific assembling instructions,
see appropriate chapter in this manual.

BG 55, BG 65, BG 85, SH 55, SH 85

English

The suction tube must be properly
mounted and the catcher bag mounted
and closed when you use the unit in the
vacuum mode.

Hold the unit firmly at all times with both
hands on the two handles. Wear the
catcher bag shoulder strap over your left
shoulder, not across your chest. This
enables you to quickly remove the
power tool and catcher bag in an
emergency.

To reduce the risk of per­sonal injury from fire,
never attempt to pick up
hot or burning sub­stances (e.g. smoldering
ashes, glowing
cigarettes).

To reduce the risk of fatal
injury from fire or explo­sion, never attempt to
pick up combustible fluids
(e.g. gasoline) or materi­als soaked in
combustible fluids.

Switch off the
engine before
opening the intake
screen. The intake
screen must
always be closed
and secured when
the suction tube is
not mounted to
reduce the risk of
injury from con­tact with rotating
components. This
can also result in
damage to the
engine.

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 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 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).

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.

Using the Unit

Using the Blower

Your blower is designed for one-handed
operation. It must be carried by the
control handle in the right hand.

WARNING

Operate the unit only with a properly
mounted blower tube.

The round nozzle is particularly suitable
for use on uneven surfaces (e.g. fields
and lawns).

The fan nozzle (either included with unit
or available as special accessory)
produces a broad and powerful
airstream at ground level. It can be
aimed and controlled very accurately.
This nozzle is highly effective for blow­sweeping sawdust, leaves, grass
cuttings, etc. on paved surfaces.

Watch out for small creatures when
blow-sweeping in open areas, yards and
gardens.

In noise-sensitive areas, operate your
unit at the lowest possible engine speed.

If necessary, dampen the surface to be
cleaned in order to avoid creating too
much dust.

Using the Vacuum Shredder

Your vacuum shredder is designed for
two-handed operation. Hold and operate
the unit with your right hand on the
control handle and your left hand on the
assist handle.

Wear the catcher bag shoulder strap
over your left shoulder, not across your
chest. This enables you to quickly
remove the power tool and catcher bag
in an emergency.

WARNING

Operate the unit only with a properly
mounted suction tube and catcher bag.
