9 Maintenance, Repair and Storage
► Immediately discontinue using or charging
the battery. Contact the authorities in the
event of fire or explosion.
■ To reduce the risk of a short circuit, which
could lead to electric shock, fire and explosion:
► Keep STIHL AR 1000, 2000, 3000
backpack batteries dry. Protect from
rain, water and other liquids. Attach
the rain cover to the battery before
starting work in rain or in very damp
conditions.
► If a STIHL AP or AR L battery has
been exposed to rain during work,
remove it from the product and allow
it to dry indoors. Make sure it is com‐
pletely dry before charging or using.
► Never immerse any STIHL battery in
water or other liquids.
► Never bridge the battery terminals with
wires or other metallic objects.
► Keep a battery that is not in use away from
small metal objects capable of conducting
electricity (e.g., paper clips, nails, coins,
keys).
► Store the battery indoors in a dry room.
► Never store the battery in damp or corro‐
sive environments or in conditions that
could lead to corrosion of its metal compo‐
nents.
► Never store the battery in the power tool.
► When storing the battery, maintain a charge
of 40 % to 60 % for STIHL AP series batter‐
ies and a charge of 30 % to 45 % for STIHL
AR series batteries (2 green LEDs).
► If storing the battery in the charger, discon‐
nect the charger from the outlet.
► Protect the battery from exposure to corro‐
sive agents such as garden chemicals and
de-icing salts.
► Protect the battery from exposure to con‐
ductive liquids such as salt water.
► Do not attempt to repair, open or disassem‐
ble the battery. There are no user-servicea‐
ble parts inside.
■ Leaking battery fluid is potentially harmful and
can cause skin and eye irritation, chemical
burns and other serious personal injury.
► Avoid contact with skin and eyes.
► Use an inert absorbent such as sand on
spilled battery fluid.
► In the event of accidental contact, immedi‐
ately rinse the contact area thoroughly with
mild soap and water.
► If fluid gets into your eye(s): do not rub.
Rinse water over the open eye(s) for at
least 15 minutes and seek medical atten‐
tion.

■ A battery fire can be dangerous. To reduce the
risk of severe personal injury and property
damage in the event of fire:
► Evacuate the area. Fire can spread rapidly.
Stay clear of any vapors generated and
maintain a safe distance.
► Contact the fire department.
► Although water can be used to put out a
battery fire, use of a multi-purpose dry
chemical fire extinguisher is preferable.
► Consult the fire department regarding
proper disposal of a burned battery.

Warnings and Instructions
WARNING
■ There are no user-authorized repairs for the
battery or chain saw. To reduce the risk of fire,
electric shock or other personal injury and
property damage:
► Users may carry out only the cleaning and
maintenance operations described in this
manual.
► Strictly follow the cleaning and maintenance
instructions in the appropriate sections of
this instruction manual.
► STIHL recommends that all repair work be
performed by authorized STIHL servicing
dealers.
■ Unintentional starting may result in personal
injury or property damage. To reduce the risk
of personal injury and property damage from
unintentional starting:
► Engage the chain brake by moving
the front hand guard forward to
and remove the battery before
inspecting the chain saw or carrying
out any cleaning, maintenance or
repair work, before storing, and any
other time it is not in use.
■ The bar and chain are the only user-servicea‐
ble parts of the chain saw. Proper mainte‐
nance will help maintain cutting performance
and reduce the risk of personal injury caused
by chain derailment and reactive forces.
► Wear gloves when handling the saw chain.
► Keep the chain, guide bar and sprocket
clean.
► Replace the chain and guide bar when they
become worn or damaged.
► Keep the chain sharp and at proper tension.
► Tighten all nuts, bolts and screws after
each use.
