IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - This manual contains important safety and
operating instructions for battery charger Models AC532710.
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
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.

8
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 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.

9
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.

10
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

11
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
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.

12
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
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.
