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.
Determine the voltage of the battery by referring to the vehicle owner’s manual 

3.11 

and make sure that the output voltage selector switch is set to the correct 

voltage. If the charger has an adjustable charge rate, charge the battery in the 

lowest rate first.

Make sure that the charger cable clips make tight connections.
