IMPORTANT SAFEGUARDS

IMPORTANT SAFETY INSTRUCTIONS

“1. SAVE THESE INSTRUCTIONS” - This manual contains important safety and
operating instructions.

Do not expose charger to rain or snow.2.

Use of an attachment not recommended in this manual may result in a risk of re, 3.
electric shock, or injury to persons.

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS -6.
Charger should be grounded to reduce risk of electric shock. Charger is equipped
with an electric cord having an equipment-grounding conductor and a grounding
plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.

DANGER - Never alter AC cord or plug provided - if it will not t outlet, have
proper outlet installed by a qualied electrician. Improper connection can result in a

risk of an electric shock.
This battery charger is for use on a nominal 120-volt circuit, and has a grounding
plug that looks like the plug illustrated in (A), below. A temporary adapter, which
looks like the adapter illustrated in (B), may be used to connect this plug to a two­pole receptacle as shown in (B) if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet can be

installed by a qualied electrician.

DANGER - Before using adapter as illustrated, be certain that center screw
of outlet plate is grounded. The green-colored rigid ear or lug extending from

adapter must be connected to a properly grounded outlet- make certain it is
grounded. If necessary, replace original outlet cover plate screw with a longer
screw that will secure adapter ear or lug to outlet cover plate and make ground
connection to grounded outlet.

Do not operate this charger with a damaged cord or plug – replace the cord or plug 7.
immediately.

Do not operate charger if it has received a sharp blow, been dropped, or otherwise 8.

damaged in any way; take it to a qualied serviceman.

Do not disassemble charger; take it to a qualied serviceman when service or 9.

repair is required. Incorrect reassembly may result in a risk of electric shock or

re.

To reduce risk of electric shock, unplug charger from outlet before attempting any 10.
maintenance or cleaning.

WARNING - RISK OF EXPLOSIVE GASES.11.

Working in the vicinity of a lead-acid battery is dangerous. Batteries generate a.
explosive gases during normal battery operation. For this reason, it is of utmost

Page 3For technical questions, please call 1-800-444-3353.SKU 67855

importance that each time before
using your charger, you read this
and follow the instructions exactly.

To reduce the risk of the battery b.
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.

Use this charger for charging h.
LEAD-ACID batteries only. It is not
intended to supply power to a low
voltage electrical system other than
in an automotive 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.

NEVER charge a frozen battery.i.

PERSONAL PRECAUTIONS12.

Someone should be within range of a.
your voice, or close enough to come
to your aid, when you work near a
lead-acid battery.

Have plenty of fresh water and soap b.
nearby in case battery acid contacts
skin, clothing, or eyes.

Wear complete eye protection and c.
clothing protection. Avoid touching
eyes while working near battery.

If battery acid contacts skin or d.
clothing, wash immediately with
soap and water. If acid enters eye,

immediately ood with running cold

water for at least 10 minutes and get
medical attention immediately.

NEVER smoke or allow a spark or e.

ame in vicinity of battery or engine.

Be extra cautious to reduce risk of f.
dropping a metal tool onto battery. It
might spark or short-circuit battery or
other electrical part that may cause
an explosion.

Remove personal metal items such g.
as rings, bracelets, necklaces, and
watches when working near a lead­acid battery. A lead-acid battery can
produce a short-circuit current high
enough to weld a ring or a similar
metal object, causing a severe burn.

PREPARING TO CHARGE 13.
BATTERY

If it becomes necessary to remove a.
the battery from the vehicle to
charge, always remove grounded

terminal from battery rst. Make

sure all accessories in the vehicle
are off, so as not to cause an arc.

Be sure area around battery is well b.
ventilated while battery is being
charged. Gases can be forcefully
blown away, by using a piece of
cardboard or other non-metallic
material such as a fan.

Clean battery terminals. Be careful c.
to keep corrosion from coming in
contact with eyes.

Add distilled water in each cell until d.

battery acid reaches level specied

by battery manufacturer. This helps
purge excessive gas from cells. Do

not overll. For a battery without cell

caps, carefully follow manufacturer’s
recharging instructions.

Study all battery manufacturer’s e.

specic precautions such as

removing or not removing cell caps
while charging and recommended
rates of charge.

Determine voltage of battery by f.
referring to car owner’s manual

Page 4 For technical questions, please call 1-800-444-3353. SKU 67855

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 LOCATION14.

Locate charger as far away from a.
battery as the DC cable permits.

Never place charger directly above b.
battery being charged; gases from
battery will corrode and damage
charger.

Never allow battery acid to drip on c.

charger when lling battery.

Do not operate charger in a closed-d.
in area or restrict ventilation in any
way.

Do not set a battery on top of e.
charger.

DC CONNECTION PRECAUTIONS15.

Connect and disconnect DC output a.
clips only after removing AC cord
from electric outlet. Never allow
clips to touch each other.

Attach clips to battery and chassis b.
as indicated in the following steps
(16 and 17):

Follow these steps when battery is 16.
installed in vehicle. A spark near
battery may cause battery explosion.
To reduce risk of a spark near battery:

Position AC and DC cords to reduce a.
the risk of damage by hood, door, or
moving engine parts.

Stay clear of fan blades, belts, b.
pulleys, and other parts that can
cause injury to persons.

Check polarity of battery posts. c.
POSITIVE (POS, P, +) battery post

usually has larger diameter than
NEGATIVE (NEG, N, -) post.

Determine which battery post d.
is grounded (connected) to the
chassis. If negative post is
grounded to chassis (as in most
vehicles), see (e). If the positive
post is grounded to the chassis, see
(f).

For negative-grounded vehicle, e.
connect POSITIVE (RED) clip from
battery charger to POSITIVE (POS,
P, +) ungrounded post of battery.
Connect NEGATIVE (BLACK) clip
to vehicle chassis or engine block
away from battery. Do not connect
clip to the carburetor, fuel lines, or
sheet-metal body parts. Connect
to a heavy gauge metal part of the
frame or engine block.

For positive-grounded vehicle, only f.
connect NEGATIVE (BLACK) clip
from battery charger to NEGATIVE
(NEG, N, -) ungrounded post of
battery. Connect POSITIVE (RED)
clip to vehicle chassis or engine
block away from battery. Do not
connect clip to the carburetor, fuel
lines, or sheet-metal body parts.
Connect to a heavy gauge metal
part of the frame or engine block.

When disconnecting charger g.
disconnect AC cord, remove clip
from vehicle chassis, and then
remove clip from battery terminal.

See operating instructions for length h.
of charge information.
