WARNING
Have your STIHL dealer show you how
to operate your backpack battery.
Observe all apllicable local safety
regulations, standards and ordinances.
WARNING
Do not lend or rent your battery without
the instruction manual. Be sure that
anyone using it understands the
information contained in this manual.
WARNING
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the battery.
WARNING
Minors should never be allowed to use
this backpack battery. Bystanders,
especially children, and animals should
not be allowed in the area where it is in
use.
Safe use of a battery involves
1. the battery
2. the use of the battery.
THE BATTERY
For illustrations and definitions of the
battery see the chapter on "Main Parts".
WARNING
Risk of fire, explosion
and / or burns, including
chemical burns. Do not
disassemble, crush, heat
above 212 °F (100 °C),
expose to fire or incinerate. Never expose the
battery to microwaves or
high pressures.
Do not place the battery on or near fires,
stoves or in other high-temperature
locations. Do not place the battery in
direct sunlight when not in use or store it
inside a vehicle in hot weather. Doing so
may cause the battery to generate heat,
rupture or ignite. Using the battery in this
manner may also result in a loss of
performance and a shortened life.
In case of fire: stay clear of any vapors
or gases generated, taking wind
direction into account. If possible without
danger, remove battery from the vicinity
of the fire. In principle, cooling the
battery or extinguishing the fire with
water is possible. It is preferable to
extinguish the fire with a multipurpose
dry chemical fire extinguisher. As for any
fire, evacuate the area and fight the fire
from a safe distance. Once the fire has
been extinguished, the area should be
monitored (fire watch) in case of a flareup, until the battery has cooled
sufficiently. Contact the proper
authorities immediately for appropriate
handling and safe disposal. Restrict
access to the area until completion of
clean-up. Do not touch the burnt battery
or any spilled liquids. Use inert
absorbent to absorb spilled liquids.
Use and store the battery only within a
temperature range from
14 °F (-10 °C) and no
more than 122 °F
(+ 50 °C).
Protect the battery from direct sunlight
when it is not in use.
Immediately discontinue use of the
battery if, while using, charging or
storing, it emits smoke, an unusual
smell, feels hot or appears abnormal in
any other way.
Charge the battery before use.
If four light emitting diodes on the battery
flash red (see "Light Emitting Diodes
(LEDs) on Battery") and a rapid
sucession of short beeps sound for
several seconds (see "Acoustic Signal"),
the battery is not functioning properly –
disconnect the battery from the power
tool, take it off your back, check its
condition and contact your STIHL
servicing dealer immediately.
WARNING
If the battery emits smoke, heats up,
smells, makes noises or shows signs of
deformation, disconnect it from the
power tool, take it off your back, put it
down and immediately move a safe
distance away. Keep children and
animals away from the work area. Keep
battery away from combustible
materials.
Use the battery only with the harness
supplied – it must not be combined with
any other carrying straps (e.g. shoulder
strap, full harness, etc.).
AR 2000, AR 3000

English
6988BA001 KN
Do not place or hang the battery in an
elevated position (e.g. branches) – it
may fall down.
Never sit or stand on the battery. Never
place objects on the battery – do not
stack several batteries on top of one
another.
Protect from rain – do not
immerse in fluids.
WARNING
Do not charge or use a defective,
damaged or deformed battery. Do not
open, drop, hit or damage battery. The
battery contains safety features and
devices, which, if, damaged, may cause
the battery to generate heat, rupture or
ignite.
Never insert objects into the cooling
slots of the AP adapter that connects the
battery to the power tool.
Inspect the AP adapter, the adapter's
contacts, the contacts of the plug of the
connecting cord and the connecting
cord for damage at regular intervals. If
any damage is found, contact your
STIHL servicing dealer. Do not continue
using or charging a malfunctioning,
damaged, cracked or deformed battery,
connecting cord or AP adapter.
Never bridge the adapter's contacts and
the contacts of the plug of the
connecting cord with metallic objects
(short circuit). The battery may be
damaged by a short circuit. Keep a
battery that is not in use away from
metal objects (e.g. nails, coins, jewelry).
Do not use metal containers for
transporting batteries.
WARNING
Fluid may leak from the battery if it is
damaged or is not used properly – avoid
contact with the skin! Leaking battery
fluid can cause skin irritation and
chemical burns. In the event of
accidental contact, wash affected areas
of skin with plenty of water and soap. If
battery fluid gets in the eye(s), do not rub
your eye(s) and rinse with plenty of
water for 15 minutes at least. Also seek
medical assistance.
Accessories and Spare Parts
Only use parts and accessories that are
explicity approved for this battery by
STIHL. If you have any questions in this
respect, consult your STIHL servicing
dealer.
STIHL recommends the use of genuine
STIHL replacement parts and
accessories. They are specifically
designed to match the product and meet
your performance requirements.
THE USE OF THE BATTERY
Transporting the Battery
Disconnect the battery from the power
tool – even when carrying it for short
distances. This avoids the risk of
accidental startup.
Carry the battery by the handle or on
your back.
In vehicles: Properly secure the battery
to prevent turnover and damage.
WARNING
Special precautions must be taken when
transporting a damaged or
malfunctioning battery. To reduce the
risk of accidents, always contact your
STIHL servicing dealer before
transporting such a battery.
Cleaning the Battery
Always clean dust and dirt off the battery
– do not use any grease solvents for this
purpose.
Clean plastic surfaces with a cloth. Do
not use aggressive detergents. They
may damage the plastic.
Do not spray the battery with water.
Do not use a pressure washer to clean
your battery. The solid jet of water may
damage parts of the battery and cause
malfunctions.
Storing the Battery
Disconnect the battery from the power
tool or charger.

Recommendation: Fully charge the
battery before using it for the first time.
NConnect the charger to the power
supply – mains voltage and
operating voltage of the charger
must be the same – see
"Connecting Charger to Power
Supply".
Operate the charger only in enclosed
and dry rooms at ambient temperatures

Charging begins as soon as the
LEDs (5) on the battery glow green –
see "LEDs on Battery".
Charge time is dependent on a number
of factors, such as the battery's
condition and the ambient temperature.
The battery becomes hot during
operation. 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.
