1. WARNING: Wear complete eye protection and clothing
protection, when working with lead-acid batteries.
2. Make sure someone is within range of your voice or close
enough to come to your aid when you work with or near a
lead-acid battery.
3. Have plenty of fresh water and soap nearby for use if battery
acid contacts skin, clothing, or eyes. If battery acid contacts
skin or clothing, wash immediately with soap and water.
4. Avoid touching your eyes while working with a battery. Acid
particles (corrosion) may get into your eyes! If acid enters
your eye, immediately flood eye with running cold water for
at least 10 minutes. Get medical attention immediately.
5. Remove all personal metal items such as rings, bracelets,

Charger should be grounded to reduce the risk of electric shock.
Charger is equipped with an electric cord having an equipment ground-
ing conductor and a grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accordance with all local
codes and ordinances. This battery charger is designed for use on a
nominal 120 volt circuit and has a grounded plug that looks like the plug
illustrated in FIGURE 1 (A). This plug should be used in a grounded
outlet. The plug pins must fit the receptacle (outlet).
ADAPTER: A temporary adapter, as shown in FIGURE 1 (B) and (C),
may be used to connect the charger plug to a two pole receptacle
(outlet), as shown in FIGURE 1 (B).
NOTE: The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
DANGER: Never alter the AC cord or plug provided. If it will not fit outlet, have a proper outlet installed by a qualified electrician. Improper connection can
result in a risk of an electrical shock. DANGER: Before using an adapter, as illustrated, be certain that the center screw of the outlet plate is grounded.
The green-colored rigid ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If necessary,
replace original outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet cover plate and make ground connection to
grounded outlet.

1. Make sure that the voltage of the battery and the charger match.
Select battery charger switch, if this model has one, accordingly.
2. Clean battery terminals. Take care to keep corrosion from coming in
contact with your eyes.
3. If required, add distilled water in each cell until battery acid reaches
levels specified by battery manufacturer. This helps purge exces-
sive gas from cells. Do not overfill. For a battery without cell caps,
carefully follow manufacturer's recharging instructions.
4. Study all battery manufacturer's specific precautions, such as re-
moving or not removing cell caps while charging, and recommended
rates of charge.
5. Be sure area around battery is well ventilated while battery is being
charged. Gas can be forcefully blown away by using a piece of
cardboard or other non-metallic material as a fan.
6. If necessary to remove battery from vehicle to charge, always
remove grounded terminal from battery first. Make sure all accesso-
ries in the vehicle are off, so as not to cause an arc.
7. A marine (boat) battery must be removed and charged on shore. To
charge it on board requires equipment specially designed for marine

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.
6. Take care not to drop a metal tool or other metal onto the
battery. Metal may cause sparking or short circuit the battery
or another electrical device. Sparking may cause an
explosion.
7. Always operate battery charger in an open well ventilated
area.
8. NEVER smoke or allow a spark or flame in the vicinity of the
battery or engine. Batteries generate explosive gases!
