WARNING = RISK OF EXPLOSIVE GASES
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BAT-
TERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY
OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT
EACH TIME BEFORE USING YOUR CHARGER, YOU READ THIS MANUAL
AND FOLLOW THE INSTRUCTIONS EXACTLY.
To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity
of battery. Review cautionary markings on these products and on engine.

reproductive harm. Wash hands after
handling.
• Read all instructions and cautions
printed on the battery charger, battery,
and vehicle or equipment using bat-
tery.
• Use charger only on lead-acid type
rechargeabte batteries, such as those
used in cars, trucks, tractors, air-
planes, vans, RVs, trolling motors, etc.
This charger is not intended to supply
power to a low voltage electrical
system other than in a starter-motor
application.
• Never use charger for charging dry
cell batteries that are commonly used
with home appliances like radios, ste-
reos, remote controls, etc. These bat-
teries may burst and cause personal
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 electri-
cal shock.
o
WARNING: 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 wilt 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.

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.
• Wear complete eye and clothing
protection when working with lead-
acid batteries.
Make 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 at-
tention.
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 medi-
cal attention.
• Remove all personal metal items
from your body such as rings, brace-
lets, necklaces and watches, while
working with a lead-acid battery. A bat-
tery 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 the 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.

enough for its length and for the AC
ampere rating, as specified in the chart

It is important that you read and follow these guidelines while you are preparing to
charge the battery.
• Make sure that you have a 12 volt
lead-acid battery. Determine voltage of
battery by referring to vehicle owner's
manual orthe battery markings. Charge
battery initially at charger's lowest
rate.
• Clean the batteryterminals. Becareful to
keep corrosion from getting inor around
your eyes or on your hands.
• Wearsafetygtasses. See additionat"Per-
sonal Safety Precautions" on page 4.
• Ifrequired, for batteries with removable
vent caps, add distilled water to each cell
until the battery acid reaches the level
recommended bythe manufacturer. This
wilt help purge excessive gases from the
cells. Be careful not tooverfill. Ifyou have
a sealed battery with non-removable
vent caps, no action is necessary.
• Take time to read all of the battery
manufacturer's specific precautions,
such as removing or not removing vent
caps white charging, and recommended
rates of charge.
• Be sure that the area around the bat-
tery is well ventilated while it is being
charged. Gas can be forcefully blown
away by using a piece of cardboard or
other nonmetallic material as a fan.
• If it is necessary to remove the battery
from the vehicle to charge it, always
remove the grounded terminal from the
battery first. Turn off all vehicle acces-
sories to avoid sparks from occurring.
• NOTE: A marine (boat) battery installed
in a boat must be removed and charged
on shore.
