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

2.8 Wear complete eye and body protection, including safety goggles
and protective clothing. Avoid touching your eyes while working
near the battery.
2.9 If battery acid contacts your skin or clothing, immediately wash
the area with soap and water. If acid enters your eye, immediately
ood the eye with cold running water for at least 10 minutes and
get medical attention right away.
2.10 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 rst. 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 Add distilled water to each cell until the battery acid reaches the
level specied by the battery manufacturer. Do not overll. For
a battery without removable cell caps, such as valve regulated
lead acid batteries (VRLA), carefully follow the manufacturer’s
recharging instructions.
3.5 Read, understand and follow all instructions for the charger,
battery, vehicle and any equipment used near the battery and
charger. Before charging, study all of the battery manufacturer’s
specic precautions and recommended rates of charge.
3.6 Determine the voltage of the battery by referring to the vehicle
owner’s manual and make sure that the output voltage is correct.
