3. Keep plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes. Avoid touching eyes while working near a lead-acid battery. If battery
acid contacts skin or clothing, wash immediately with soap and water. If acid enters the
eyes, immediately flood eyes with running cold water for at least 10 minutes and get medical
attention immediately.
4. NEVER smoke or allow a spark or flame in the vicinity of a lead-acid battery or vehicle
engine.
5. Use caution to reduce the risk of dropping a metal tool onto a lead-acid battery. The
tool may spark or short circuit the battery or other electrical part that may cause an
explosion.
6. 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 other metal item, causing a severe burn.
7. Use the Battery Charger for charging lead-acid batteries only. This Battery Charger 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. Dry-cell
batteries may burst and cause serious personal injury and/or property damage. NEVER
charge a frozen battery.
Preparing To Charge:
1. If it is necessary to remove the battery from a vehicle to charge, always remove the
grounded terminal from the battery first. Make sure all accessories in the vehicle are off,
so as not to cause an arc.
2. Make sure the area around the battery is well ventilated while the battery is being
charged.
3. Clean the battery terminals prior to charging the battery.
4. Add distilled water in each cell until the battery acid reaches the level specified by the
battery manufacturer. This helps purge excessive gas from the cells. Do not overfill. For
a battery without cell caps, carefully follow the battery manufacturer’s recharging instruc
tions.
5. Determine the voltage of the battery by referring to the vehicle owner’s manual, con-
firm it is 12 volt.
Charger Location:
1. Always locate the Battery Charger as far away from the battery as the Charger’s DC
cables permit.
2. Never place the Battery Charger directly above the battery being charged. Gases from
the battery will corrode and damage the Battery Charger.
3. Never allow battery acid to drip on the Battery Charger.
