Personal Safety Precautions
For your own personal safety, please follow the following precautions:
•
Wear complete eye and clothing
protection when working with lead-
acidbatteries.
•
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
severeburn.
•
Be sure that someone is within range
of your voice to come to your aid if
needed while you work with or are near
alead-acidbattery.
•
•
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.
•
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.
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.
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.

recommended rates of charge.
•
Make sure that you have a 12 volt or 6
volt lead-acid battery. Set the selector
switch to match the voltage rating of
the battery to be charged.
•
•
•
Wear safety glasses. See additional
"PersonalSafetyPrecautions"on
page4.
•
•
Clean the battery terminals. Be careful
to keep corrosion from getting in or
aroundyoureyes.
Be sure that the area around the
battery is well ventilated while it is
beingcharged.
For batteries with removable cell caps,
if required by the manufacturer, add
distilled water to each cell until the
battery acid reaches the level
recommended. This will help purge
excessive gases from the cells. Be
careful not to overfill. If you have a
sealed battery without cell caps, no
action is necessary. Continue to the
next step listed below.
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
accessories to avoid sparks from
occuring.
NOTE: A marine battery installed in a boat
must be removed and charged on shore.

Take time to read all battery
manufacturer’s specific precautions,
such as removing or not removing cell
USING YOUR BATTERY CHARGER
To obtain the best results from your battery charger, you must know how to use it
properly. This section will tell you how to set the controls, how to charge a battery in or
out of a vehicle, and how to use the engine start feature.
SETTING THE CONTROLS
All controls are located on the front of
the charger. Follow these instructions to
obtain the correct charge level for your
battery.
• Use the right switch to select a charge
rate—2 AMP charge, 12 AMP charge,
or 75 AMP ENGINE START.
Battery Voltage:
SELECTOR SWITCHES:
Your charger has three switches:
Select the voltage of your battery. The
most common applications will be 12
volt.
• Use the left switch to match the
battery voltage—either 6 or 12 volt.
• Use the center switch to select a
charge type—MANUAL, AUTOMATIC
DEEP CYCLE or AUTOMATIC
REGULAR.
6 VOLT
12 VOLT

AMMETER:
Charge Type:
The ammeter indicates the measured
amount of amperes being drawn by the
battery. When you first start charging a
battery, the reading will be high, with
the needle near 12 using the 12 amp
charging rate.
• Use the MANUAL setting only if you
check the charging progress frequently.
The charger will not stop charging when
the battery reaches full charge, possibly
damaging the battery if left on too long.
You must monitor and unplug the
charger when battery is fully charged.
•
In the MANUAL setting, as the battery
charges, the needle will fall to about 5
to 6 amps, indicating a charged
battery.
• Use the AUTOMATIC DEEP CYCLE
setting for all deep cycle battery
charging. The charger will automatically
stop charging when the battery reaches
full charge and begin charging again
when battery requires.
•
In both AUTOMATIC settings, the
needle will fall to zero and the
charger will shut off when the
charger’s control circuit senses a full
charge. A freshly charged battery’s
voltage will drop shortly after charging
stops, and the charger, if left con-
nected, may resume charging. This
off-and-on cycling will continue until
the battery’s voltage no longer drops
enough to restart the charger.
• Use the AUTOMATIC REGULAR
setting for all but deep cycle batteries.
The charger will automatically stop
charging when the battery reaches
full charge and begin charging again
when battery requires.
• A severely discharged battery may not
have enough charge to start the
control circuit in an AUTOMATIC
setting. In this case, charge on
MANUAL until the battery has enough
charge to accept an AUTOMATIC
setting.
•
At the 2 amp charging rate you will
notice very little needle movement.
When cranking the engine while using
the ENGINE START feature, the needle
will swing into the Start (red) area of the
scale.

large batteries.The lower the charge
rate, the longer it will take to charge the
battery.
LED INDICATOR:
• Use the 12 AMP rate setting for
automotive, deep cycle and other large
batteries.
The green LED INDICATOR will glow
when the charger senses that the
battery has reached a full charge.
• Use the 75 AMP ENGINE START setting
only to assist in cranking the engine.
• When using the MANUAL charge rate,
stop charging when the LED glows and
the AMMETER needle is about 5 to 6
amps in the 12 Amp setting.
