1. SAVE THESE INSTRUCTIONS –
This manual contains important safety and
operating instructions for this battery charger.
2. Do not expose charger to rain or snow.
3. Use of an attachment not recommended or sold
by the battery charger manufacturer may result in
a risk of fire, electric shock, or injury to persons.
4. To reduce risk of damage to electric
plug and cord, pull by plug rather than
cord when disconnecting charger.
5. An extension cord should not be used unless
absolutely necessary. Use of improper extension
cord could result in a risk of fire and electric shock.
If an extension cord must be used, make sure:
a. That pins on plug of extension cord
are the same number, size, and shape
as those of plug on charger;
b. That extension cord is properly wired
and in good electrical condition; and
c. That wire size is large enough for AC ampere
rating of charger as specified in Table A.

* If the input rating of a charger is given in watts rather than in
amperes, the corresponding ampere rating is to be determined by
dividing the wattage rating by the voltage rating – for example:

7. Do not operate charger if it has received a sharp
blow, been dropped, or otherwise damaged in
any way; take it to a qualified serviceman.
8. Do not disassemble charger; take it to a
qualified serviceman when service or repair
is required. Incorrect reassembly may
result in a risk of electric shock or fire.
9. To reduce risk of electric shock, unplug charger
from outlet before attempting any maintenance or
cleaning. Turning off controls will not reduce this risk.
10. 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.
11. 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 flood eye with
running cold water for at least 10 minutes
and get medical attention immediately.
e. NEVER smoke or allow a spark or flame
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.
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

12. PREPARING TO CHARGE
13. CHARGER LOCATION
14. DC CONNECTION PRECAUTIONS
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.
a. If necessary to remove battery from vehicle
to charge, always remove grounded terminal
from battery first. Make sure all accessories in
the vehicle are off, 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 cell until battery
acid reaches level specified by battery
manufacturer. Do not overfill. 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
specific precautions while charging and
recommended rates of charge.
f. Determine voltage of battery by referring to vehicle
owner’s manual and make sure it matches output
rating of battery charger. If charger has adjustable
charge rate, charge battery initially at lowest rate.
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 specific gravity or filling 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.
a. Connect and disconnect DC output clips only
after setting any charger switches to “off” position
and removing AC cord from electric outlet.
Never allow clips to touch each other.
b. Attach clips to battery and chassis as indicated
in 15(e), 15(f), and 16(b) through 16(d).
15. 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 cables 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) 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 carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy
gauge metal part of the frame or engine block.
f. For positive-grounded vehicle, 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 carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy
gauge metal part of the frame or engine block.
g. When disconnecting charger,
disconnect AC cord, remove clip from
vehicle chassis, and then remove
clip from battery terminal.
h. See operating instructions for
length of charge information.
16. 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 clip 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 clip to free end of cable.
e. Do not face battery when making final connection.
