(40 °C).
Allow the charger to cool down normally
– do not cover it.
Never bridge the contacts of the charger
with metallic objects (e.g. nails, coins,
jewelry) – short circuit. The charger may
be damaged by a short circuit.
In the event of smoke or fire in the
charger, disconnect it from outlet
immediately.
WARNING
To reduce the risk of electric shock or
short circuit, do not insert any objects
into the charger's cooling slots.
WARNING
The charger heats up during the
charging process. Do not operate on an
easily combustible surface (e.g. paper,
texiles) or in an easily combustible
environment – risk of fire.
WARNING
Do not operate in a hazardous location,
i.e. in a location where there are
combustible liquids (fumes), vapors or
dusts. Chargers can produce sparks,
which may ignite the dust or vapors –
risk of explosion.

Working Conditions
WARNING
Operate your machine outdoors under
good visibility and daylight conditions
only. Work carefully.
The motor is not water
proof. Never work with
the power tool in the rain
or in wet or very damp
locations.
Do not leave the machine outdoors in
the rain.
WARNING
Static electricity may build-up while
blow-sweeping large quantities of very
dusty material and suddenly discharge
in certain unfavorable conditions (e.g.
very dry work area.
WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. Control dust at the source
where possible. Use good work
practices, such as operating the unit so
that the wind or operating process
directs any dust raised by the power tool
away from the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
-
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
WARNING
If the substance being blown is a
commercial substance, review,
understand and follow all warnings and
instructions contained on the label and
in the material safety data sheet for that
substance and/or consult the material
manufacturer/supplier. The state of
California and some other authorities,
for instance, have published lists of
substances known to cause cancer,
reproductive toxicity, etc.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal illness,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be blowing or
otherwise disturbing asbestos,
immediately contact EPA, your
employer or a local OSHA
representative.
WARNING
Dust with silica in its composition may
contain crystalline silica. Silica is a basic
component of sand, quartz, brick, clay,
granite and numerous other minerals
and rocks, including masonry and
concrete products. Repeated and/or
substantial inhalation of airborne
crystalline silica can cause serious or
fatal respiratory disease, including
silicosis. In addition, the state of
California and some other authorities
have listed respirable crystalline silica as
a substance known to cause cancer.
When encountering such materials,
always follow the respiratory
precautions mentioned above.
Pay attention to the direction of the wind,
i.e., do not work against the wind.
Operating Instructions
WARNING

contact with the blower fan, never
operate your blower without a properly
mounted blower tube or with a damaged
intake screen.
WARNING
Never insert any foreign object into the
air intake of the machine or into the
nozzle of the blower. It will damage the
blower fan and may cause serious injury
to the operator or bystanders as a result
of the object or broken parts being
thrown out at high speed.
Do not place the blower on the ground
when operating at high speed, because
small objects such as sand, grass, dust,
etc. may be pulled into the air intake and
damage the fan wheel. It is best to turn
the machine off when putting it on the
ground.
After Finishing Work
Always clean dust and dirt off the power
tool – do not use any grease solvents for
this purpose.
MAINTENANCE, REPAIR AND
STORING

Description of Operation Using the Unit
The power tool is operated with a
rechargeable battery. Use only STIHL
chargers to recharge the battery.
Data exchange
The power tool, battery and charger
communicate with each other. The
charger charges the battery and the
battery supplies the necessary power
only if the data exchange functions
properly. For this reason you should
operate your power tool only with the
approved STIHL batteries and STIHL
chargers.
Your blower is designed for one-handed
operation. It can be carried by the
control handle in either the right or left
hand.
Watch out for small animals when blowsweeping in open areas, yards and
gardens.
Nozzles
WARNING
To reduce the risk of injury, operate the
unit only with a properly mounted
nozzle.
The round nozzle is particularly suitable
for use on uneven surfaces (e.g. fields
and lawns).
The fan nozzle (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 and similar materials from flat
surfaces.
Mounting the nozzle
N Push the nozzle (1) onto the blower
tube (2) – the lug (3) must engage
the groove (4).
N Lock the nozzle (1) by rotating it in
