2.

may burst causing personal injury and property damage.

3. Do not expose the charger to rain or snow if specifically warned on the unit not to do so.

4. 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.

5. To reduce the risk of damage to the electric plug and cord, pull by the plug rather than the cord when disconnecting the charger.

6. Make sure the cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.

7. An extension cord should not be used unless absolutely necessary. Use of a improper extension cord could result in a risk of fire and

electric shock. If an extension cord must be used, make sure:

a. That the pins on the plug of extension cord are the same number, size, and shape as those of the plug on the charger;
b. That the extension cord is properly wired and in good condition; and
c. If the length of the extension cord is less than 25 feet, use a 16AWG cord, If 50 feet- 12AWG, 100 feet-10AWG, 150 feet-8AWG.

8. Do not operate the charger with a damaged cord or plug, replace them immediately.

9. Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified

serviceman.

10. Do not disassemble the charger, take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in
risk of electric shock or fire.

11. To reduce the risk of electric shock, unplug the charger form the outlet before attempting any maintenance or cleaning. Turning off the
controls will not reduce this risk.

WARNING - RISK OF EXPLOSIVE GASES

12.
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 EACH TIME BEFORE USING
YOUR CHARGER, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY.

b. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and manufacturer

of any equipment you intend to use in vicinity of the battery. Review cautionary markings on these products and on the engine.

PERSONAL PRECAUTIONS

13.
a. Someone should be within range of your voice or close enough 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 enter eyes, immediately flood eyes 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 the battery or engine.
f. Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short circuit the battery or other electrical

parts that may cause an 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 this charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low-voltage electrical system other

than in an automotive application. Do not use this 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

14.
a. If necessary to remove battery from vehicle to charge, always remove the grounded terminal from the battery first. Make sure all

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

b. Be sure the area around the battery is well ventilated while the battery is being charged. Gas can be forcefully blown away by using

a piece of cardboard or other non-metallic material as a fan.

c. Clean the 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 the battery manufacturer. This helps purge excessive gas

from cells. Do not overfill. For a battery without cell caps, carefully follow the manufacturer's recharging instructions.

e. Study all battery manufacturer's specific precautions such as removing or not removing the cell caps while charging and the

recommended rates of charge.

f. Determine voltage of the battery by referring to the car owner's manual and make sure that the output voltage selector switch is set at

the correct voltage. If the charger has adjustable charge rate, charge the battery initially at the lowest rate.

15. CHARGER LOCATION
a. Locate the charger as far away from the battery as the DC cables permit.
b. Never place the charger directly above the battery being charged; gases from the battery will corrode and damage the charger.
c. Never allow battery acid to drop on the charger when reading the specific gravity or filling battery,
d. Do not operate the charger in a closed-in area, or restrict ventilation in any way.
e. Do not set a battery on top of the charger.

DC CONNECTION PRECAUTIONS

16.
a. Connect and disconnect the DC output clamps only after setting the charger switches to the OFF position and removing the AC cord

from the electric outlet. Never allow the clamps to touch each other.

b. Attach the DC clamps to the battery post and twist or rock back and forth several times to make a good connection. This tends to

keep the clamps from slipping off the terminals and helps to reduce the risk of sparking.

STOP/GO LITE INSTRUCTIONS

17.

When used properly, the STOP/GO LITE will indicate whether clamp connections will be correct.
Connect the positive (red) clamp to the positive (POS, P, +) battery post. Touch the contact button
of the negative (black) clamp to the other battery post. Observe the L.E.D. lights in the STOP/GO
LITE:

GREEN LIGHT: The first connection is correct. Make the second clamp connection per instructions.
RED LIGHT: The first connection made with the positive clamp to the battery is incorrect. Attach the

positive clamp to the other battery post and retest.

RED AND GREEN LIGHT: The battery charger is turned on. Turn the charger "OFF" and retest.
NO LIGHT: Check for a shorted or open battery. Clean any corrosion from the clamp jaws and the

battery post and retest. If still no light, use a voltmeter or other means to make certain you have
properly identified the polarity of the battery post. Then attach the clamps per instructions,
disregarding the STOP/GO LITE.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE. A

SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO
REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

a. Read the section "STOP/GO LITE INSTRUCTIONS" before proceeding.
b. Position the AC and DC cords to reduce the risk of damage by the hood, door, or moving engine parts.
c. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
d. Check the polarity of the battery post. The POSITIVE (POS, P, +) battery post usually has a larger diameter than the NEGATIVE

(NEG, N, -) post.

e. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in

most vehicles), see item "e". If the positive post is grounded to the chassis, see item "f".

f. For negative-grounded vehicles, connect the POSITIVE (RED) clamp from the battery charger to the POSITIVE (POS, P, +)

ungrounded post of the battery. Touch the contact button of the STOP/GO LITE to the NEGATIVE (NEG, N, -) battery post.
Interpret the light and take appropriate action. When the green light is on, connect the NEGATIVE (BLACK) clamp to the vehicle
chassis, heavy gauge metal part of the frame, or engine block, away from the battery. Do not connect to the carburetor, fuel lines, or
sheet metal body parts.

g. For positive-grounded vehicles, connect the POSITIVE (RED) clamp from the battery charger to the POSITIVE (POS, P, +) battery

post. Touch the contact button of the STOP/GO LITE to the NEGATIVE (NEG, N, -) battery post. Interpret the light and take
appropriate action. When the green light is on, disconnect the POSITIVE (RED) clamp from the battery. Attach the NEGATIVE
(BLACK) clamp to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Attach the POSITIVE (RED) clamp to the vehicle
chassis or engine away from the battery. Do not connect the clamp to the carburetor, fuel lines, or sheet-metal body parts. Connect
to a heavy gauge metal part of the frame or engine block.

h. When disconnecting the charger, turn the switches to OFF, disconnect the AC cord, remove the clamp from the vehicle chassis, and

then remove the clamp from the battery terminal.

i. See the operating instructions for length of charge information.

FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE. A SPARK NEAR THE BATTERY

19.

MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

a. Read section "STOP/GO LITE INSTRUCTIONS" before proceeding.
b. Check the polarity of the battery post. The POSITIVE (POS, P, +) usually has a larger

diameter than the NEGATIVE (NEG, N, -) post.

c. Attach at least a 24 inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE (NEG,

N, -) battery post.

d. Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) post of the battery.
e. Touch the contact button of the STOP/GO LITE to the free end of the battery cable. If the red

light comes on, reverse the connections to the battery and retest. When the green light come
on, position yourself and the free end of the cable as far away from the battery as possible, then connect the NEGATIVE (BLACK)
charger clamp to the free end of cable.

f. Do not face the battery when making the final connection.
