near a lead-acid battery.
2.2 Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
2.3 Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
2.4 If battery acid contacts skin or clothing, wash immediately with soap and water.
If acid enters eye, immediately ood eye with running cold water for at least 10
minutes and get medical attention immediately.
2.5 NEVER smoke or allow a spark or ame in vicinity of battery or engine.
2.6 Be extra cautious, to reduce risk of dropping a metal tool onto battery. It might spark
or short-circuit battery or other electrical part that may cause explosion.
2.7 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.
2.8 Use the charger for charging only 6V and 12V LEAD-ACID (STD, AGM or GEL)
rechargeable batteries. It is not intended to supply power to a low voltage electrical
system other than in a starter-motor application. Do not use 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.
2.9 NEVER charge a frozen battery.
3. PREPARING TO CHARGE
3.1 If necessary to remove battery from vehicle to charge, always remove grounded
terminal from battery rst. Make sure all accessories in the vehicle are off, so as
not to cause an arc.
3.2 Be sure area around battery is well ventilated while battery is being charged.
3.3 Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
3.4 Add distilled water in each cell until battery acid reaches level specied by battery
manufacturer. Do not overll. For a battery without removable cell caps, such as valve
regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
3.5 Study all battery manufacturer’s specic precautions while charging and
recommended rates of charge.
3.6 Determine voltage of battery by referring to car owner’s manual and make
sure that output voltage selector switch is set at correct voltage (if applicable).
If charger has adjustable charge rate, charge battery initially at lowest rate.
