To reduce the risk of a battery explosion, follow these instructions and those 2.2
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.
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
2.3
Be extra cautious to reduce the risk of dropping a metal tool onto the battery. 2.4
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
2.5
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.
NEVER charge a frozen battery.
2.6
NEVER overcharge a battery. 2.7
PREPARING TO CHARGE 3.
Risk of contact with battery acid. Battery acid is a
highly corrosive sulfuric acid.
Consider having someone close enough by to come to your aid when you work 3.1
near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts your
3.2
skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and
3.3
protective clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area with
3.4
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.
If battery acid is accidentally swallowed, drink milk, the whites of eggs or water.
3.5
DO NOT induce vomiting. Seek medical attention immediately.
If it is necessary to remove the battery from the vehicle to charge it, always
3.6
remove the grounded terminal first. Make sure all of the accessories in the
vehicle are off to prevent arcing.
Be sure the area around the battery is well ventilated while the battery is being
3.7
charged.
Clean the battery terminals before charging the battery. During cleaning, keep
3.8
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.
Add distilled water to each cell until the battery acid reaches the level specified
3.9
by the battery manufacturer. Do not overfill. For a battery without removable
cell caps, such as valve regulated lead acid batteries (VRLA), carefully follow
the manufacturer’s recharging instructions.
Read, understand and follow all instructions for the charger, battery, vehicle
3.10
and any equipment used near the battery and charger. Study all of the battery
manufacturer’s specific precautions while charging and recommended rates of
charge.
