RISK OF EXPLOSIVE gASES.

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

1.10 

BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY 

OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT  

YOU FOLLOW ALL INSTRUCTIONS IN THIS MANUAL EACH TIME YOU USE  

THE CHARGER.
To reduce the risk of a battery explosion, follow all instructions in this manual and those 

1.11 

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

1.12 

arcs and sparks. If used in a garage, locate this charger 18 inches or more above  

floor level.

PERSONAL PRECAUTIONS

2. 

RISK OF EXPLOSIVE gASES.

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

2.1 

Remove personal metal items such as rings, bracelets, necklaces and watches when 

2.2 

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 

2.3 

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 

2.4 

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.
NEVER charge a frozen battery.

2.5 

NEVER overcharge a battery.

2.6 

Consider having someone close enough by to come to your aid when you work near a 

2.7 

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

2.8 

clothing or eyes.
