IMPORTANT SAFETY INSTRUCTION
WARNING: RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. 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 manufacturers of the battery and any equipment you intend to
use in the vicinity of the battery. Review the cautionary markings on these
productions and on the engine.
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 fire,

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 qualified professional for
inspection or repair.
•Do not disassemble the charger. Take it to a qualified professional when
service or repair is required.
•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 flammable materials, such as carpeting,
upholstery, paper, cardboard, etc.
•Never smoke or allow sparks or flames in the vicinity of the battery or
engine.
WARNING: RISK OF EXPLOSIVE GAS.
•Operate the charger as far away from the battery as DC charger cables
permit. 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 overcharge a 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 clips together when the charger is energized.
•When disconnecting the battery charger, pull by the plug, not by the cord.
Pulling on the cord may cause damage to the cord or plug.
•Do not operate the charger with damaged cord or plug.
•NEVER allow battery acid to drop onto the charger.
PERSONAL SAFETY PRECAUTIOUS
•Wear complete eye and clothing protection 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, skins, or clothing. Wash immediately with
soda and water and seek medical attention.

•If battery acid comes in contact with eyes, flush eyes immediately for a
minimum of 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.
•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 grounded terminal first.
ASSEMBLY INSTRUCTIONS
Remove all cord wraps and uncoil the cables prior to using the battery charger.
This battery charger is for use on a nominal 120 volt circuit.
USING AN EXTENSION CORD
Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the
next heavier gage. The smaller the gage number, the heavier the cord.
PREPARING TO CHARGE
1. Determine voltage of battery to be maintained by referring to the vehicle
manual.
2. If it is necessary to remove battery from vehicle to charge, or to clean
terminal, always remove grounded terminal from battery first. Make sure all
accessories in the vehicle are off, so as not to cause an arc.
3. Clean battery terminals. Do not allow corrosion to come in contact with
eyes.
4. Add distilled water in each cell until battery acid reaches level specified by
battery manufacturer. This helps purge excessive gas from cells. Do not
overfill. For a battery without cell caps (maintenance free), carefully follow
manufacturer's charging instructions.
5. Study all battery manufacturer's specific precautions, such as removing or
not removing cell caps while charging, and recommended rates of charge.

6. Remove battery completely from boat/airplane or any confined area before
charging. Area around battery should be well ventilated while battery is
being charged. Do not operate while an enclosed area.
CAUTION: This battery charger does not detect, diagnose or analyze the
condition of the battery. Attempting to charge/maintain a battery with an
abnormal condition can further damage the battery. If in doubt, have the battery
checked by a qualified professional prior to using this unit.
IMPORTANT: Do not start the vehicle with the charger connected to the AC
outlet, or it could result in damage to the charger.
CHARGER LOCATION
1. Locate battery charger as far away from battery as cables permit.
2. Charge above freezing temperature and below40 degree Celsius(C) (104
degree Fahrenheit).
3. NEVER place battery charger directly above battery being charged; gases
from battery will corrode and damage charger.
4. NEVER allow battery acid to drip on battery charger when reading gravity or
filling battery.
5. NEVER operate battery charger in a closed-in area or restrict ventilation in
any way.
6. Marine batteries must be removed and charged on shore. To charge it on
board requires equipment specially designed for marine use. This unit is
NOT designed for such use.
7. Do not set a battery on top of battery charger.
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE AN EXPLOSION. TO
REDUCE RISK OF A SPARK NEAR THE BATTERY: CONNECT AND DISCONNECT
DC OUTPUT CLAMPS AND RING TERMINALS ONLY AFTER REMOVING AC
CORD FROM ELECTRIC OUTPUT.
Connection Precautious
1. Disconnect AC cord from electric outlet before connecting or disconnecting
DC clamps.
2. Never allow clamps to touch each other.
