WORKING IN THE 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 YOU 

FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.

To reduce the risk of a battery explosion, follow these instructions and those published 

by the battery manufacturer and the manufacturer of any equipment you intend to use  

in the vicinity of the battery. Review the cautionary markings on these products and on 

the engine.

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.

Be extra cautious, to reduce the risk of dropping a metal tool onto the battery. It might 

spark or short-circuit the battery or other electrical part that may cause an explosion.

Use this charger for charging LEAD-ACID batteries only. It is not intended to supply 

power to a low voltage electrical system. 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.

NEVER charge a frozen battery.

Consider having someone nearby to come to your aid when you work near a  

lead-acid battery. Have plenty of fresh water and soap nearby in case battery acid 

contacts your skin, clothing or eyes.

If battery acid contacts your skin or clothing, immediately wash the area with soap and

at least 10 minutes and get medical attention right away. If battery acid is accidentally 

swallowed, drink milk, the whites of eggs or water. DO NOT induce vomiting. Seek 

medical attention immediately.

Remove all cord wraps and uncoil the cables prior to using the battery charger. 

If it is necessary to remove the battery from the vehicle to charge it, always remove

prevent arcing.

Clean the battery terminals before charging the battery. During cleaning, keep airborne 

corrosion from coming into contact with your eyes, nose and mouth. Use baking soda 

and water to neutralize the battery acid and help eliminate airborne corrosion. Do not 

touch your eyes, nose or mouth.
