IMPORTANT SAFETY INSTRUCTIONS
WARNING – RISK OF EXPLOSIVE GASES
WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES 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.
SAVE THESE INSTRUCTIONS
This manual contains important safety and operating instructions for battery charger
model SC-7500A.
• WARNING: Handling the cord on this
product or cords associated with accessories sold with this product, may
expose you to lead, a chemical known
to the State of California to cause
cancer and birth defects or other
reproductive harm. Wash hands after
handling.
• 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, airplanes, 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, stereos, remote controls, etc. These batteries may burst and cause personal
injury.
• Do not disassemble charger. Take it
to a qualied service professional if
service or repair is required. Incorrect
assembly may result in re 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.
• WARNING: Battery chargers get hot
during operation and must have proper
ventilation. Air needs to ow around
entire charger. Do not set charger on
ammable 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
uid (electrolyte) becomes frozen, bring
battery into a warm area to thaw before
you begin charging.
Never allow battery acid to drip on char-
ger when reading specic gravity or lling
battery.
Never set a battery on top of the charger.
3
Never place charger directly above battery
being charged. The gases from the battery
will corrode and damage the charger.
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 qualied professional
for inspection and repair.
Be sure to position the charger power cord
PERSONAL SAFETY PRECAUTIONS
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 leadacid 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 attention.
• Avoid touching your eyes while
working with a battery. Acid particles
(corrosion) may get into your eyes. If
this occurs, ush 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 the battery charger in
an open, well-ventilated area.
• Never smoke or allow a spark or ame
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.

BEFORE USING YOUR BATTERY CHARGER
It is important to understand your charger's requirements. This section will tell you about
your charger's electrical requirements and how to prepare a battery for charging.
PLUGGING IT IN
Your charger requires a 120V AC 2-prong
wall outlet receptacle installed according
to all local codes and ordinances.
ASSEMBLING YOUR CHARGER
Included with your battery charger are two
cord wrap cleats for storage of the clamp
cables.
To install, align the two tabs to correspond
with the two receptacles and push until you
hear a snap.
Wrap clamp cables after unplugging the
power cord from the AC wall outlet and
store your charger in a dry location.
USING AN EXTENSION CORD
The use of an extension cord is not recommended. If you must use an extension
cord, please make sure that you follow
these guidelines:
• Make sure that the pins on charger's
power cord t rmly into the extension
cord, and that the extension cord ts
rmly into the receptacle.
• Check that the extension cord is properly
wired and in good electrical condition.
• Make sure that the wire size is large
enough for its length and for the AC
ampere rating, as specied in the chart
below.
MINIMUM RECOMMENDED EXTENSION CORD
Length of Cord, in Feet 25 50 100 150
AWG* Size of Cord 18 16 12 10
*AWG=American Wire Gauge
PREPARING YOUR BATTERY TO BE CHARGED
It is important that you read and follow these guidelines while you are preparing to charge
the battery.
• Make sure that you have a 6 or 12 volt
lead-acid battery. Determine voltage of
battery by referring to vehicle owner’s
manual or the battery markings. Charge
battery initially at charger’s lowest rate.
• Clean the battery terminals. Be careful to
keep corrosion from getting in or around
your eyes or on your hands.
• Wear safety glasses. See additional “Personal Safety Precautions” on page 4.
• If required, for batteries with removable
vent caps, add distilled water to each cell
until the battery acid reaches the level
recommended by the manufacturer. This
will help purge excessive gases from the
cells. Be careful not to overll. If you 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 while charging, and recommended
rates of charge.
• Be sure that the area around the battery 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 rst. Turn off all vehicle accessories to avoid sparks from occurring.
• NOTE: A marine (boat) battery installed
in a boat must be removed and charged
on shore.
