• Risk of short circuit – A battery pack will short circuit if
a metal object makes a connection between the positive
and negative contacts on the battery pack. Do not place a
battery pack near anything that may cause a short circuit,
such as paperclips, coins, keys, screws, nails and other
metallic objects. A short‑circuited battery pack poses a risk
of fire and severe personal injury.
• Store your battery packs and charger in a cool, dry
place – Ideally, store the battery packs at 59°F (15°C) and
charged to at least 40%. Do not store the battery packs or
charger where temperatures may exceed 105ºF (40.5ºC),
such as in direct sunlight or inside a vehicle, or where
temperatures may drop below 41°F (5°C).
NOTE: Prevent the battery packs from freezing. Battery
packs that were stored below 32°F (0°C) for more than 60
minutes must be discarded.
• Charge before use – The battery packs supplied with your
tool is only partially charged. The battery packs have to be
fully charged before using the snow blower for the first time.
• Battery Aging – Lithium‑ion batteries are subject to a
natural aging process. A battery pack must be replaced at
the latest when its capacity falls to just 80% of its capacity
when new. Weakened cells in an aged battery pack are no
longer capable of meeting the high power requirements
needed for the proper operation of your tool, and therefore
pose a safety risk.
• Do not exhaustively discharge the battery packs –
A complete discharge will damage the battery cells. The
most common cause of exhaustive discharge is lengthy
storage. Stop working as soon as the performance of a
battery falls noticeably or the electronic protection system
triggers. For optimum battery performance, charge the
battery packs frequently. Place the battery packs in storage
only after it has been fully charged.
• Do not overload the battery packs – Protect the tool and
batteries from overloading. Overloads will quickly result in
overheating and cell damage inside the battery housing
even if it is not apparent externally. For safety reasons, the
integrated protective cutoff will activate to switch off the
equipment. After regular use, allow the battery packs to
cool to room temperature before recharging them.
IMPORTANT! Do not attempt to turn on the tool if the
protective cutoff has been activated. This may damage the
battery packs.
• Outlet voltage – Please check the data marked on the
rating label of the battery charger. Be sure that the voltage
of the power supply matches that marked on the rating
label. Never connect it to a different mains voltage. Never
modify the plug in any way. Do not use any adapter plugs
with grounded tools.
• Charger use – Do not use the supplied battery charger to
charge other types of battery packs or tools.
• Do not overcharge battery packs – Unplug the charger
when not in use. Frequently overcharging the battery packs
will result in cell damage. Do not leave batteries charging
for days on end.
• Battery pack abnormalities – Do not use batteries that
have suffered swelling or deformation or those that exhibit
other atypical symptoms (gassing, hissing, cracking, etc.).
• Electrostatic discharge – When handling batteries, be
wary of electrostatic charge. Electrostatic discharges can
damage the electronic protection system and the battery
cells. To avoid electrostatic discharges, never touch the
battery terminals.
