CHARGER LOCATION PRECAUTIONS
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!
PERSONAL PRECAUTIONS AND SAFETY

GROUND AND AC POWER CORD CONNECTIONS

GROUNDING
SCREW
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
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"
Never place charger directly above the battery being charged,
gases from battery could damage the charger.
Never allow battery acid to drip on the charger when reading
specific gravity of filling battery.
Never operate charger in a closed in area, or restrict ventila-
tion in any way.
Do not set battery on top of the charger.
E.
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 bat-
tery without cell caps, carefully follow manufacturer's re-
charging 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 us-
ing a piece of cardboard or other non-metallic material as a
fan.
6. If necessary to remove battery from vehicle to charge, al-
ways 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.
