SAVE THESE INSTRUCTIONS.
1.
You may need to refer to these instructions at a later date.
CAUTION.
2. To reduce risk of injury, charge only wet cell, lead-acid, automotive type rechargeable batteries. Other types of batteries may
burst causing personal injury and 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. That wire in cord is proper size as follows: Minimum recommended AWG wire size for various length extension cords used with this
charger:
Length of Cord, Feet
AWG Size
Do not operate the charger with a damaged cord or plug, replace them immediately.
8.
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.
9.
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.
