RISK OF EXPLOSIVE GASES.
1.10 

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.

1.11 

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.

1.12 

This charger employs parts, such as switches and circuit breakers, that tend to produce 

arcs and sparks. If used in a garage, locate this charger 18 inches (46 cm) or more 

above floor level.

2. 

PERSONAL PRECAUTIONS

RISK OF EXPLOSIVE GASES.
2.1 

NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.

2.2 

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.

2.3 

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.

2.4 

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

to a low voltage electrical system other than in a starter-motor 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.

2.5 

NEVER charge a frozen battery.

2.6 

NEVER overcharge a battery.

2.7 

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

battery.

2.8 

Have plenty of fresh water and soap nearby in case battery acid contacts your skin, 

clothing or eyes.

2.9 

Wear complete eye and body protection, including safety goggles and protective 

clothing. Avoid touching your eyes while working near the battery.

2.10 

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

water. If acid enters your eye, immediately flood the eye with cold running water for at 

least 10 minutes and get medical attention right away.

2.11 

If battery acid is accidentally swallowed, drink milk, the whites of eggs or water. DO NOT 

induce vomiting. Seek medical attention immediately.

3. 

PREPARING TO CHARGE

RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS 

A HIGHLY CORROSIVE SULFURIC ACID.
3.1 

If it is necessary to remove the battery from the vehicle to 

charge it, always remove the grounded terminal first. Make sure 

all of the accessories in the vehicle are off to prevent arcing.

3.2 

Be sure the area around the battery is well ventilated while 

the battery is being charged.

3.3 

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.

3.4 

This charger is only designed to charge AGM/VRLA batteries that do not allow for 

the battery caps to be removed. For any other type of battery, follow the battery 

manufacturer’s instruction for maintenance.
