2. PERSONAL PRECAUTIONS
RISK OF EXPLOSIVE GASES.
WARNING
2.1 NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
2.2 Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead-acid or lithium ion battery. These batteries can
produce a short-circuit current high enough to weld a ring or the like to metal,
causing a severe burn.
2.3 Be extra cautious, to reduce the risk of dropping a metal tool onto the battery. It might
spark or short-circuit the battery or other electrical part that may cause an explosion.
2.4 Use this charger for charging 12V lead-acid, calcium, gel and AGM-type rechargeable
batteries with rated capacities of 40-230Ah, and 24V lead-acid, calcium, gel and AGM-type
rechargeable batteries with rated capacities of 60-230Ah. It is not intended to 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
or lithium ion batteries used in cell phones, laptops, power tools, etc. These batteries may
burst and cause injury to persons and damage to property.
2.5 NEVER charge a frozen battery.
2.6 Consider having someone nearby to come to your aid when you work near a lead-acid battery.
2.7 Have plenty of fresh water and soap nearby, in case battery acid contacts your skin,
clothing or eyes.
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 flood 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
WARNING WARNING
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 specified 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.
3.5 Read, understand and follow all instructions for the charger, battery, vehicle 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.
3.6 Determine the voltage of the battery by referring to the vehicle owner's manual 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.
3.7 Make sure that the charger cable clips make tight connections.
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 first. Make sure all
of the accessories in the vehicle are off, to prevent arcing.
