• Do not crush, drop or damage battery pack – Do not
use the battery pack or charger if they have sustained
a sharp blow, been dropped, run over or have been
damaged in any way (i.e. pierced with a nail, hit with a
hammer, stepped on, etc.).
• Do not disassemble – Incorrect reassembly may pose
a serious risk of electric shock, fire or exposure to toxic
battery chemicals. If the battery or charger is damaged,
contact an authorized Snow Joe
call the Snow Joe + Sun Joe
®
1-866-SNOWJOE (1-866-766-9563) for assistance.
• Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth.
If damaged, battery chemicals will react violently with air.
Use rubber or neoprene gloves to safely dispose of the
battery. If skin is exposed to battery chemicals, wash the
affected area with soap and water. If eyes are exposed
to battery chemicals, immediately flush with water for 20
minutes and seek medical attention. Remove and dispose
of contaminated clothing.
• 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 pack and charger in a cool, dry
place – Ideally, store the battery pack at 59°F (15°C) and
charged to at least 40%. Do not store the battery pack 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 pack 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 pack supplied with your
tool is only partially charged. The battery pack has to be
fully charged before using the pruner 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 pack –
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 pack frequently. Place the battery pack in storage
only after it has been fully charged.

• Do not overload the battery pack – Protect the tool and
battery 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 pack to
cool to room temperature before recharging it.
IMPORTANT! Do not attempt to turn on the tool if the
protective cutoff has been activated. This may damage
the battery pack.
• 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 pack
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.
