AMP OWNER’S MANUAL

BATTERY CHARGER & MAINTAINER 12

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.

GENERAL BATTERY SAFETY

1. Before you use your battery charger, be sure to read all
instructions and cautions printed on:

• Battery Charger

• Battery

• Vehicle or unit using battery

2. Use battery charger on LEAD ACID type rechargeable batteries

only, such as used in autos, trucks, tractors, airp lanes, vans, RV's
trolling motors, etc. Charger is not intended to supply power to
low-voltage electrical system other than in an automotive
application.
WARNING: Do no use battery charger for charging drycell
batteries that are commonly used with home applianc es. These
batteries may burst and cause injury to persons and damage to
property.

3. Use only attachments recommended or sold by manufacturer. Use

of non-recommended attachments may result in fire, electric
shock, or injury.

4. When disconnecting the battery charger, pull by the plug not by

the cord. Pulling on the cord may cause damage to cord or plug.

5. Locate battery power cord so it cannot be stepped on,
tripped over, or subjected to damage or stress.

6. Do not operate charger with damaged cord or plug. Have
cord replaced immediately.

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
professional for inspection and repair.

8. Do not disassemble charger. Take it to a qualified professional
when service or repair is required. Incorrect reassembly may
result in electric shock or fire.

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

VOLT

10. Do not use an extension cord unless absolutely necessary.
Use of an improper extension cord could result in fire or electric
shock. If an extension cord must be used, make sure that:

• Pins on plug of extension cord are the same number, size, and

shape as those of plug on charger.

• Extension cord is properly wired and in good electrical

condition.

• Wire size is large enough for AC ampere rating of charger, as

specified below:

Length of cord (feet): 25 50 100 150
AWG size of cord: 18 18 18 16

11. Always charge battery in a well ventilated area.
NEVER operate in a closed-in or restricted area without adequate
ventilation.
WARNING: Risk of explosive gas.

12. Locate charger as far away from battery as DC charger
cables permit.

13. Do not expose charger to rain or snow.

14. NEVER charge a frozen battery. If battery fluid (electrolyte)

is frozen, bring into a warm area to thaw before charging. 15.
NEVER allow battery acid to drip on charger when reading
specific gravity or filling battery.

16. NEVER set a battery on top of charger.

17. NEVER place charger directly above battery being charged.

Gases from battery will corrode and damage charger.

18. NEVER touch the battery clips together when the charger
is energized.

19. NEVER crank engine with charger attached to battery, and
120 volt line.

PERSONAL PRECAUTIONS AND SAFETY

1. WARNING: Wear complete eye protection and clothing
protection, when working with lead-acid batteries.

2. Make sure someone is within range of your voice or close

enough to come to your aid when you work with or near a
lead-acid battery. '

3. Have plenty of fresh water and soap nearby for use if

battery acid contacts skin, clothing, or eyes. If battery acid
contacts skin or clothing, wash immediately with soap and
water.

4. Avoid touching your eyes while working with a battery.

Acid particles (corrosio n) may get into your eyes! If acid
enters your eye, immediately flood eye with running cold
water for at least 10 minutes. Get medical attention
immediately.

5. Remove all personal metal items such as rings, bracelets,

GROUND AND AC POWER CORD CONNECTIONS

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 plugge d into an outlet that is properly inst alled
and grounded in accordance with all local codes and
ordinances.

This battery charger is designed for use on a nominal
120volt circuit and has a grounded plug that looks like the plug
illustrated FIGURE 1 (A). This plug should be used in a
grounded outlet. The plug pins must fit the receptacle (outlet).

ADAPTER: A temporary adapter, as shown in FIGURE 1
(B) and (C), may be used to connect the charger plug to a two
pole receptacle (outlet) as shown FIGURE 1 (B).

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.

6. Take care not to drop a metal tool or other metal onto the
battery. Metal may cause sparking or short circuit the
battery or another electrical devise. Sparking may cause
an explosion.

7. Always operate battery charger in an open well ventilated
area.

8. NEVER smoke or allow a spark or flame in the v i ci ni ty of
the batter

or engine. Batteries generate explosive gases!

NOTE: The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.

DANGER: NEVER alter the AC cord or plug provided. If it will not fit outlet, have proper outlet installed by a qualified electrician.

Improper connection can result in a risk of an electric shock. DANGER: Before using an 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.

PREPARING TO CHARGE

1. 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.

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

3. Clean battery terminals. Be careful to keep corrosion from
coming in contact with eyes.
Keep the battery terminals clean and ti ght. Use terminal
protectors to prevent corrosion.

4. If battery has rem ovable filler vent s, check periodically to
make sure batter y electrolyt e (liquid) cover s the plates. If
liquid is down, add water to bring l evel up. Thi s also help s
purge excessive gas from the cell s.
NOTE: DO NOT OVERFILL (OVERFILLING COULD RESULT
IN DAMAGE).

5. Study all battery manufacturer's specific precautions such
as removing or not removing cell caps while charging, and
recommended rates of charge.

6. DO NOT use for parallel charging. Charger is designed to
charge / maintain one 12 volt battery.

CHARGER LOCATION PRECAUTION

Never place charger directly above battery being charged;

gases from battery could damage charger.

Never allow battery acid to drip on charger when reading

specific gravity or filling battery.

Do not operate charger in a closed-in area or restrict

ventilation in any way.

Do not set battery on top of charger.
