WARNING: To reduce the risk of
explosion, explosive gases, or injury
while using your battery charger, follow
the precautions listed below:
• Read all instructions and cautions
printed on the battery charger,
battery, and vehicle or equipment
using battery.
• Use charger only on lead-acid type
rechargeable batteries, such as those
used in cars, trucks, tractors, air-
planes, vans, RV's, trolling motors,
etc. This charger is not intended to
supply power to a low voltage
electrical system.
• Use only attachments recommended
or sold by Sears. The use of attach-
ments not recommended by Sears
may result in fire, electric shock, or
injury.
• Do not disassemble charger. Take it
to a qualified service professional if
service or repair is required. Incorrect
assembly may result in fire or
electrical shock.
• To reduce risk of electrical shock,
unplug the charger from the outlet
before attempting any maintenance
or cleaning.
• Always charge battery in a well-
ventilated area.
• Battery chargers get hot during
operation and must have proper
ventilation. Air needs to flow around
entire charger.
• Do not set charger on flammable
materials like carpeting, upholstery,
paper, cardboard, etc. Charger may
damage leather and melt plastic and
rubber.
HELP US HELP YOU--
Remember:
• Place charger as far away from the
battery being charged as the charger
cables will permit.
• Do not expose charger to rain or
snow.
• Never charge a frozen battery. If
battery fluid (electrolyte) becomes
frozen, bring battery into a warm area
to thaw before you begin charging.
• Never allow battery acid to drip on
charger when reading specific gravity
or filling battery.
• Never set a battery on top of the
charger.
• Never place charger directly above
battery being charged. The gases
from the battery will corrode and
damage the charger.
• Never use charger for charging dry-
cell batteries that are commonly used
with home appliances like radios,
stereos, remote controls, etc. These
batteries may burst and cause
personal injury.
• Never touch the battery clamps
together when the charger is on. You
could cause a spark.
• Never operate charger if it has
received a hard blow, been dropped,
or otherwise damaged. Take it to a
qualified professional for inspection
and repair.
• Be sure to position the charger power
cord to prevent it from being stepped
on, tripped over, or damaged.
• Never pull out the plug by the cord
when unplugging the charger. Pulling
on the cord may cause damage to the
cord or the plug.
• Do not operate the charger if it has a
damaged power cord or plug. Have
the cord replaced.
For your own personal safety, please follow the following precautions:
• Wear complete eye and clothing
protection when working with lead-
acid batteries,
• Be sure that someone is within range
of your voice to come to your aid if
needed while you work with or are
near a lead-acid battery.
• Have plenty of fresh water and
soap nearby for use in case battery
acid contacts your eyes, skin, or
clothing. If this happens, wash
immediately with soap and water.
Then get medical attention.
• Avoid touching your eyes while
working with a battery. Acid particles
(corrosion) may get into your eyes. If
this occurs, flush eyes immediately
with running cold water for at least 10
minutes. Then immediately get
medical attention.
Remove all personal metal items
from your body such as rings,
bracelets, necklaces and watches,
while working with a lead-acid battery.
A battery can produce a short circuit
current high enough to weld a ring (or
the like) to metal, causing a severe
burn.
• Take care not to drop any metal tool
or metal object onto the battery. This
may spark or short circuit the battery
or another electrical device that may
cause an explosion.
• Always operate your battery charger
in an open, well-ventilated area.
• Never smoke or allow a spark or
flame in the vicinity of the battery or
engine. Batteries generate explosive
gases.
• Neutralize any acid spills thoroughly
with baking soda before attempting to
clean up.
