AUTOMATIC-RESET CIRCU IT BREAKER prevents overload
damage to the charger.

INTRODUCTION

HOW BATTERIES CHARGE

A charger DOES NOT FORCE current into a battery - it makes a
limited amount of current available and the battery draws as much

of it as it needs, up to or slightly greater than the OUTPUT AMP

rating of the charger.

The closer a battery is to zero-charge ("dead"), the more charging

current it will want to draw. When charging begins on a "dead"
battery, a charger!s ammeter (if so equipped) will register toward

the high amps end of the scale and fall toward the zero end as the

battery becomes more fully charged. KEEP IN MIND: the
ammeter registers the amount of amperage being drawn from the

charger by the battery, not what the charger is capable of
delivering.

One would expect a battery to draw zero amps when it reaches
100% of charge. But at 100% of charge, the battery will continue

to draw a low level of current and convert it into heat within the
battery. If left connected to a MANUAL charger after reaching

100% of charge, the battery acid will begin to boil, resulting in

overcharging and possible battery damage.

But the Sears #71614 battery charger is FULLY-AUTOMATIC.

When full charge is reached, it will completely shut off the
charging current to the battery. If the battery were to discharge for
some reason, the charger will automatically resume charging the

battery until full charge is reached again.

SPARK PREVENTION

MAKE SURE NO SPARKS OR FLAMES OCCUR NEAR THE

BATTERY, especially during charging. It takes very little to ignite

the explosive gasses produced by a lead-acid battery. Read,

understand, and follow the SAFETY INSTRUCTIONS section of

this manual before attempting to work with or near a lead-acid

battery,

IMPORTANT SAFETY INSTRUCTIONS

control(s) to their "OFF" position(s) alone will not remove all
electricity from the charger.

EXPLOSION HAZARDS

WARNING! - RISK OF EXPLOSIVE GASSES!

Working Jnthe vicinity of a lead-acid battery is dangerous.

Batteries generate explosive gasses during normal operations
and, at an even higher level, during charging. If anything is
allowed to ignite these gasses, the battery may explode, sending

pieces of the battery and extremely caustic battery acid out in all

directions and with extreme force. Since just the slightest spark is
sufficient to ignite these gasses, it is of UTMOST IMPORTANCE

that you read this manual and follow the instructions exactly,

before using your battery charger each time.

BATTERY EXPLOSION CAN KILL, INJURE, AND

CAUSE PROPERTY DAMAGE! To reduce the risk of battery

explosion, read, understand, and follow these instructions,those

published by the battery manufacturer, and those of the

manufacturerof any equipment you intendto use near the battery.
Review cautionary markingson these productsand on the engine.
If unable to determine the battery manufacturerer's requirements

for charging,always charge the battery withthe cell caps in place.

Inaddition,make certain that anyone else that uses this

equipment, or is a bystander inthe vicinityof a chargingbattery,
understandand follow these safety instructionsas well.

NEVER smoke or allow a spark or flame in the vicinity of the

battery or engine.

NEVER operate the battery charger in a closed-in area or restrict

ventilation in any way.

NEVER charge a frozen battery as battery explosion can result.

NEVER connect BOTH battery charger clamps DIRECTLY to the

twoposts of the same battery. SEE OPERATING

INSTRUCTIONS FOR PROPER CONNECTION PROCEDURES.

NEVER charge batteries other than a LEAD-ACID type.
Especially, DO NOT use for charging dry-cell batteries that are

IMPORTANT SAFETY INSTRUCTIONS

commonly used with toys and home appliances. These batteries
may burst and cause injury to persons or damage property.

NEVER allow the DC output clamps to touch each other.

ALWAYS be extra cautious to reduce the risk of dropping a metal
object, such as a too!, onto or near the battery. Doing so could

produce a spark or short circuit the battery or other electrical part

that could cause an explosion.

ALWAYS make sure the area around a battery is well ventilated
while it is being charged. Gas can be forcefully blown away by
using a piece of cardboard or other non-metalic material as a fan.

ALWAYS make sure that theAC _wercord is unplugged from the

AC outlet or extension cord BEFORE connecting or disconnecting
the battery charger clamps to the battery to prevent arcing or burning.

ALWAYS locate the batter){, charger as far away from the battery

as the DC output cables w_l! permit.

ALWAYS twist or rock charger clamps back and forth several times

on the battery post and the 6ther point of connection at the time of
initial connection. This helps keep the clamps from slipping off their
points of connection which helps reduce the risk of sparking.

NOTE: DO NOT rock the clamp connected to the battery post
AFTER the second connection (at a point away from the battery)
is made or sparking may occur at the battery post.

FIRE HAZARDS

FIRE CAN KILL, INJURE, AND CAUSE PROPERTY

DAMAGE! _

NEVER use an attachment not recommended or sold by the battery

charger manufacturer for use with your specific model charger.

NEVER dissassemble the battery charger; take it to qualified

service personnel when service or repair is needed.

BA'I-rERY ACID HAZARDS

BATTERY ACID CAN CAUSE SERIOUS INJURY AND

PROPERTY DAMAGE!

ALWAYS have someone within range of your voice and close

enough to quickly come to your aid when working near a lead-acid
battery.

ALWAYS have plenty of fresh water and soap nearby in case

battery acid contacts eyes, skin, Orclothing.

ALWAYS wear complete eye and clothing protection and avoid

touchingeyes while working with a battery,

ALWAYS act QUICKLY if contact with battery acid is made. If

acid contacts skin or clothing, wash IMMEDIATELY with soap and

water. If acid enters eye, IMMEDIATELY flood eye with running
cold water for at least 10 minutes and get medical attention

IMMEDIATELY.

SHORT CIRCUIT HAZARDS

ELECTRICAL SHORT CIRCUITS CAN INJURE!

ALWAYS remove personal metal items such as rings, bracelets,

and watches when working with a lead-acid battery. A lead-acid
battery can produce a short circuit current high enough to weld a
ring orthe like to metal causing a severe burn.
