Despite all of the safety precautions, caution must always be taken when handling batteries. The following
points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are
used. Incorrect handling of the battery pack can cause cell damage.
• Avoid dangerous environments – Do not charge the
battery pack in rain, snow or in damp or wet locations.
Do not use the battery pack or charger in the presence
of explosive atmospheres (gaseous fumes, dust or flam-
mable materials) because sparks may be generated when
inserting or removing the battery pack, which could lead
to a fire.
• Charge in a well-ventilated area – Do not block the
charger vents. Keep them clear to allow for proper ven-
tilation. Do not allow smoking or open flames near a
charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery charg-
ing is -4°F to 113°F. Do not charge the battery outside in
freezing weather; charge it at room temperature.
• Maintain charger cord – When unplugging the char-
ger, pull the plug, not the cord, from the receptacle to
reduce the risk of damage to the electrical plug and cord.
Never carry the charger by its cord or yank it by the cord
to disconnect it from the receptacle. Keep the cord away
from heat, oil and sharp edges. Make sure the cord will
not be stepped on, tripped over or subjected to dam-
age or stress when the charger is in use. Do not use the
charger with a damaged cord or plug. Replace a dam-
aged charger immediately.
• Do not use an extension cord unless it is absolutely
necessary – Using the wrong, damaged or improperly
wired extension cord poses a risk of fire and electric
shock. If an extension cord must be used, plug the char-
ger into a properly wired 16 gauge or larger extension
cord with the female plug matching the male plug on the
charger. Make sure that the extension cord is in good
electrical condition.
• Charger is rated for 120 volt AC only – The charger
must be plugged into an appropriate receptacle.
• Use only recommended attachments – Use of an at-
tachment not recommended or sold by WEN Products
may result in risk of fire, electric shock or personal in-
jury.
• Unplug charger when not in use – Make sure to re-
move battery packs from unplugged chargers.
BATTERY & CHARGER SAFETY WARNINGS
WARNING! To reduce the risk of electric shock,
always unplug the charger before performing any
cleaning or maintenance. Do not allow water to
flow into the charger. Use a Ground Fault Circuit
Interrupter (GFCI) to reduce shock hazards.
• Do not burn or incinerate battery packs – Battery
packs may explode, causing personal injury or dam-
age. Toxic fumes and materials are created when battery
packs are burned.
• Do not crush, drop or damage battery packs – Do not
use the battery pack or charger if they have sustained a
sharp blow, been dropped, run over or have been dam-
aged in any way (i.e. pierced with a nail, hit with a ham-
mer, 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 are damaged,
call WEN customer service at 1-800-232-1195 for as-
sistance.
• Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth.
If a damaged battery pack leaks battery chemicals, use
rubber or neoprene gloves to safely dispose of it. If skin
is exposed to battery fluids, wash the affected area with
soap and water and rinse with vinegar. If eyes are ex-
posed to battery chemicals, immediately flush with wa-
ter for 20 minutes and seek medical attention. Remove
and dispose of contaminated clothing.
• Store your battery pack and charger in a cool, dry
place – Do not store the battery pack or charger where
temperatures may exceed 104 °F, such as in direct sun-
light or inside a vehicle or metal building during the
summer.
• Do not 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 cir-
cuit, such as paper clips, coins, keys, screws, nails and
other metallic objects. A short-circuited battery pack
poses a risk of fire and severe personal injury.
