B. PERSONAL PRECAUTIONS AND SAFETY
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,
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 devise. 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!
C. GROUND AND AC POWER CORD CONNECTIONS
Charger should be grounded to reduce the risk of electric shock.
Charger is equipped with an electric cord having an equipment
grounding 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.
FIGURE 1 GROUNDING METHODS

SCREW
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.
"Use of adapter plug not allowed in Canada"
D. PREPARING TO CHARGE
1. Make sure you have a 12 volt or a 6 volt lead-acid battery
and select battery charger switch 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 excessive 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 removing 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 accessories 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 use.
E. CHARGER LOCATION PRECAUTIONS
Never place charger directly above the battery being charged,
gases from battery could damage the charger.
Never operate charger in a closed in area, or restrict ventilation
in any way.
Never allow battery acid to drip on the charger when reading
specific gravity of filling battery.
Do not set battery on top of the charger.
