IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains important safety
and operating instructions for battery charger Model AC532713.
1. Do not expose charger to rain or snow.
2. Use of an attachment not recommended or sold by the battery charger
manufacturer may result in a risk of re, electric shock, or injury to persons.
3. To reduce risk of damage to electric plug and cord, pull by plug rather than
cord when disconnecting charger.
4. An extension cord should not be used. Use of improper extension cord could
result in a risk of re and electric shock.
5. Do not operate charger with damaged cord or plug – replace the cord or
plug immediately.
6. Do not operate charger if it has received a sharp blow, been dropped, or
otherwise damaged in any way; take it to a qualied serviceman.
7. Do not disassemble charger; take it to a qualied serviceman when service
or repair is required. Incorrect reassembly may result in a risk of electric shock
or re.
8. To reduce risk of electric shock, unplug charger from outlet before
attempting any maintenance or cleaning. Turning o controls will not reduce
this risk.
WARNING – RISK OF EXPLOSIVE GASES.
a) 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 YOU FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
b) 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 marking on these
products and on engine.
PERSONAL PRECAUTIONS
a) Consider having someone close enough by to come to your aid when you
work near a lead-acid battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes
while working near battery.
d) If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters eye, immediately ood eye with running cold water for at

5
least 10 minutes and get medical attention immediately.
e) NEVER smoke or allow a spark or ame in vicinity of battery or engine.
f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It
might spark or short-circuit battery or other electrical part that may cause
explosion.
g) Remove personal metal items such as rings, bracelets, necklaces, 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 or the like to
metal, causing a severe burn.
h) Use charger for charging a LEAD-ACID battery only. It is not intended to
supply power to a low voltage electrical system other than in a starter-motor
application. Do not use battery charger for charging dry-cell batteries that
are commonly used with home appliances. These batteries may burst and
cause injury to persons and damage to property.
i) NEVER charge a frozen battery.
PREPARING TO CHARGE
a) If necessary to remove battery from vehicle to charge, always remove
grounded terminal from battery rst. Make sure all accessories in the vehicle
are o, so as not to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact
with eyes.
d) Add distilled water in each Standard wet cell until battery acid reaches level
specied by battery manufacturer. Do not overll. For a battery without
removable cell caps, such as valve regulated lead acid batteries, carefully
follow manufacturer’s recharging instructions.
e) Study all battery manufacturer’s specic precautions while charging and
recommended rates of charge.
f) Determine voltage of battery by referring to car owner’s manual and make
sure that output voltage selector switch is set at correct voltage. If charger
has adjustable charge rate, charge battery initially at lowest rate.
CHARGER LOCATION
a) Locate charger as far away from battery as dc cables permit.
b) Never place charger directly above battery being charged; gases from
battery will corrode and damage charger.
c) Never allow battery acid to drip on charger when reading electrolyte specic
gravity or lling battery.
d) Do not operate charger in a closed-in area or restrict ventilation in any way.
e) Do not set a battery on top of charger.

6
DC CONNECTION PRECAUTIONS
a) Connect and disconnect dc output Battery Clamps only after setting any
charger switches to“o”position and removing ac cord from electric outlet.
Never allow Battery Clamps to touch each other.
b) Attach Battery Clamps to battery and chassis as indicated.
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK
NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
a) Position ac and dc cords to reduce risk of damage by hood, door, or moving
engine part.
b) Stay clear of fan blades, belts, pulleys, and other parts that can cause injury
to persons.
c) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has
larger diameter than NEGATIVE (NEG, N,–) post.
d) Determine which post of battery is grounded (connected) to the chassis. If
negative post is grounded to chassis (as in most vehicles), see (e). If positive
post is grounded to the chassis, see (f).
e) For negative-grounded vehicle, connect POSITIVE (RED) Battery Clamp from
battery charger to POSITIVE (POS, P, +) ungrounded post of battery. Connect
NEGATIVE (BLACK) Battery Clamp to vehicle chassis or engine block away
from battery. Do not connect Battery Clamp to carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy gage metal part of the frame or
engine block.
f) For positive-grounded vehicle, connect NEGATIVE (BLACK) Battery Clamp
from battery charger to NEGATIVE (NEG, N, –) ungrounded post of battery.
Connect POSITIVE (RED) Battery Clamp to vehicle chassis or engine block
away from battery. Do not connect Battery Clamp to carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy gage metal part of the frame or
engine block.
g) When disconnecting charger, turn switches to o, disconnect AC cord,
remove Battery Clamp from vehicle chassis, and then remove Battery Clamp
from battery terminal.
h) See operating instructions for length of charge information.
FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK
NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF
A SPARK NEAR BATTERY:
a) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has
a larger diameter than NEGATIVE (NEG, N, –) post

Cleaning
Unplug the charger before cleaning it with a damp cloth. Use only mild cleaning agents,
no solvents or corrosive chemicals.
Storage
If the charger is not to be used for an extended period, it should be unplugged and
stored in a dry and dust-free location and out of reach of children.
CARE AND MAINTENANCE:
b) Attach at least a 24-inch-long 6-gauge (AWG) insulated battery cable to
NEGATIVE (NEG, N, –) battery post.
c) Connect POSITIVE (RED) charger Battery Clamp to POSITIVE (POS, P, +) post
of battery.
d) Position yourself and free end of cable as far away from battery as possible –
then connect NEGATIVE (BLACK) charger Battery Clamp to free end of cable.
e) Do not face battery when making nal connection.
f) When disconnecting charger, always do so in reverse sequence of
connecting procedure and break rst connection while as far away from
battery as practical.
g) A marine (boat) battery must be removed and charged on shore. To charge
it on board requires equipment specially designed for marine use.
