The blower is designed for single­handed operation with either the right or
left hand on the control handle.

When working with the blower, always
wrap your fingers tightly around the
handle, keeping the control handle
cradled between your thumb and
forefinger. Keep your hand in this
position to have your machine under
control at all times.

To reduce the risk of stumbling and loss
of control, do not walk backward while
operating the machine.

Special care must be taken in slippery
conditions (wet ground, snow) and in
difficult, overgrown terrain. Watch for
hidden obstacles such as tree stumps,
roots and ditches to avoid stumbling. For
better footing, clear away fallen
branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.

Working Conditions

WARNING
Operate your machine outdoors under

good visibility and daylight conditions
only. Work carefully.

The power tool may be used in rain and
wetness. Dry the power tool after
finishing work.

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
with a spark 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 stop work and 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
In the event of an emergency, switch off

the motor immediately, move retaining
latch to ƒ and remove the connecting
cord.

WARNING

In order to reduce
the risk of personal
or even fatal injury
to bystanders from
blown objects
keep bystanders at
least 5 m (16 feet)
away when the
power tool is
running.

To reduce the risk of damage to
property, also maintain this distance
from such objects as vehicles or
windows.

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

Switch off the motor immediately if you
are approached.

WARNING
To reduce the risk of personal injury, do

not direct air blast towards bystanders,
since the high pressure of the air flow
can injure eyes and can blow small
objects at great speed. Do not direct
airblast towards pets.

When working in open ground and
gardens, watch out for small animals to
avoid harming them.

WARNING

The blower fan between the air intake
and output openings rotates whenever
the motor is running. In order to reduce
the risk of injury from 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

If you make a warranty claim for a

battery see STIHL AR battery instruction
manual.

Charging STIHL AP Battery

N Push the battery (1) into the

charger (2) until noticeable
resistance is felt – then push it as far
as stop.

The LED (3) on the charger comes on
when the battery is inserted – see "LED
on Charger"

Charging begins as soon as the
LEDs (4) on the battery glow green –
see "LEDs on Battery".

The charge time is dependent on a
number of factors, including battery
condition, ambient temperature, etc.,
and may therefore vary from the times
specified.

The battery heats up during operation in
the power tool. If a hot battery is inserted
in the charger, it may be necessary to
cool it down before charging. The
charging process begins only after the

battery has cooled down. The time
required for cooling may prolong the
charge time.

The battery and charger heat up during
the charging process.

AL 300, AL 500 Chargers
The AL 300 and AL 500 chargers are

equipped with a battery cooling fan.

AL 100 Charger
The AL 100 charger has no fan and

waits for the battery to cool down before
starting the charging process. The
battery is cooled by heat transfer to the
ambient air.

End of Charge
The charger switches itself off

automatically when the battery is fully
charged:

– LEDs on the battery go off.
– The LED on the charger goes off.
– The charger's fan is switched off (if

charger is so equipped)

Remove the fully charged battery from
the charger.
