6 Battery Safety
– Never expose the battery to microwaves or high 
pressures.
– Never insert objects into the battery’s cooling slots.
■ High temperatures may cause the battery to generate 
heat, rupture, leak, ignite or explode, resulting in severe or 
fatal personal injury and property damage. Exposure to 
temperatures outside the recommended temperature 
range may also reduce battery life and performance.
■ To reduce the risk of personal injury and property damage 
in the event the battery emits smoke, an unusual smell or 
feels unusually hot while using, charging or storing:
– Immediately discontinue using or charging the 
battery. Prepare to 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:
– Never bridge the battery terminals with wires or 
other metallic objects.
– Keep a battery that is not in use away from metal 
objects (e.g., paper clips, nails, coins, keys).
– Never transport or store the battery in a metal 
container.
– Store the battery indoors in a dry room.
– Never store the battery in damp or corrosive 
environments or in conditions that could lead to 
corrosion of its metal components.
– Never store the battery in the blower or charger.
– Protect the battery from exposure to corrosive 
agents such as garden chemicals and de-icing salts.
– Do not attempt to repair, open or disassemble the 
battery. There are no user-serviceable parts inside.
■ Leaking battery fluid can cause skin and eye irritation or 
chemical burns.
– Avoid contact with skin and eyes.
– Use an inert absorbent such as sand on spilled 
liquids.
– In the event of accidental contact, immediately 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 attention.
■ 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 the burned battery.
■ Dropping the battery could result in personal injury or 
property damage. To prevent the battery from falling 
during removal:
– Place the blower on a level surface.
– Position your hand behind the battery while pressing 
the locking lever. Use care when ejecting the 
battery.
– Use and store the battery only within an 
ambient temperature range of 14 °F to 
122°F (-10°C to 50°C).
– Never store the battery in direct sunlight 
or inside a vehicle in hot weather.
– Keep the battery dry. Protect it from rain, 
water, liquids and damp conditions.
– Never immerse the battery in water or 
other liquids.
