WARNING
1.6
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.
1.7 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 and on
the engine.
2. PERSONAL PRECAUTIONS
WARNING
2.1 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.
2.2 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.
2.3 Use this charger for charging LEAD-ACID batteries only. It is not intended to supply
power to a low voltage electrical system. 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.
2.4 NEVER charge a frozen battery.
2.5 Consider having someone nearby to come to your aid when you work near a
lead-acid battery. Have plenty of fresh water and soap nearby in case battery acid
contacts your skin, clothing or eyes.
2.6 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. 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
BATTERY ACID IS A HIGHLY CORROSIVE SULFURIC ACID.
3.1 Remove all cord wraps and uncoil the cables prior to using the battery charger.
3.2 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.
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. This
charger is equipped with Auto Voltage Detection of 6 or 12 volts.
3.7 Make sure that the charger cable clips make tight connections.
3.8 Included with your charger are two cord wrap cleats for storage of the clip cables. To install,
align the two tabs with the two receptacles on the back of the charger and push until you
hear a snap.
