WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES

GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. FOR THIS REASON,

IT IS IMPORTANT THAT YOU FOLLOW THESE INSTRUCTIONS EACH TIME YOU USE
THE CHARGER.

To reduce the risk of a battery explosion, follow these instructions and those published
by the manufacturer of the battery and any equipment you intend to use in the vicinity
of the battery. Review the cautionary markings on these products and on the engine.

65, this product contains chemicals known to

the State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling.

• Use the battery charger on LEAD-ACID and
AGM-type rechargeable batteries with
recommended rated capacities of 12Ah (6V)

and 22-59Ah (12V), as used in automobiles,
trucks, tractors, airplanes, vans, RVs, trolling
motors, etc. This charger is not intended to

supply power to low-voltage electrical

systems, other than in a motor-starting

application.
WARNING: Do not use battery charger with

dry cell batteries that are commonly used with
home appliances. These batteries may burst
and cause injury or damage to property.

• Use only attachments recommended or sold
by the battery charger’s manufacturer. Use
of non-recommended attachments may

result in a re, electric shock or injury.

• Locate the battery charger’s power cord so

it cannot be stepped on, tripped over, or

subjected to damage or stress.

• Do not operate the charger if it has received

a sharp blow, been dropped, or otherwise
damaged in any way. Take it to a qualied

professional for inspection and repair.

• Do not disassemble the charger. Take it to a
qualied professional when service or repair
is required.

• Keep out of reach of children.

• To reduce the risk of electric shock, unplug

the charger from the outlet before
attempting any maintenance or cleaning.

• Do not use an extension cord.

• Always charge the battery in a well-

ventilated area

• Do not set the charger on ammable
materials, such as carpeting, upholstery,

WARNING: RISK OF EXPLOSIVE GAS.

• Operate the charger as far away from the
battery as DC charger cables permit.

• Do not expose the charger to rain or snow.

• NEVER charge a frozen battery.

• NEVER set a battery on top of the charger.

• NEVER place the charger directly above a

battery being charged. Gases from the
battery will corrode and damage the charger.

• NEVER touch the battery clamps together
when the charger is energized.

• When disconnecting the battery charger, pull

PERSONAL SAFETY PRECAUTIONS

• Wear complete eye protection and

protective clothing when working near

lead-acid batteries. Always have someone
nearby for help.

• Have plenty of fresh water, soap and baking
soda nearby for use, in case battery acid
contacts your eyes, skin, or clothing. Wash
immediately with soap and water and seek

medical attention.

• If battery acid comes in contact with eyes,
ush eyes immediately for a minimum 10

minutes and get medical attention.

• Neutralize any acid spills thoroughly with

baking soda before attempting to clean up.

• Remove all personal metal items from your

body, such as rings, bracelets, necklaces

and watches. A battery can produce a short
circuit current high enough to weld a ring to

metal, causing a severe burn.

• NEVER smoke or allow a spark or ame in
the vicinity of the battery or engine.

• Do not drop a metal tool onto the battery.

• If it is necessary to remove the battery from

the vehicle to charge it, always remove the
