1. Batteries generate explosive gases during normal operation. Use in
well-ventilated area.
2. Consider having someone close enough or within the range of your
voice to come to your aid when you work near a battery.
3. Do NOT smoke, strike a match, or cause a spark in vicinity of battery or
engine. Avoid explosive gas, ames and sparks.
4. Remove all personal jewelry, such as rings, bracelets, necklaces, and
watches while working with a vehicle battery. These items may produce
a short circuit that could cause severe burns.
5. Be extra cautious to reduce risk of dropping a metal tool onto the
battery. It might spark or short-circuit a battery or other electrical hard-
ware which may cause explosion or re.
6. Wear complete eye protection, hand and clothing protection. Avoid
touching eyes while working near a battery.
7. Study all battery manufacturer’s specic precautions such as removing
or not removing cell caps while charging and recommended rates of
charge.
8. Clean battery terminals before connected with the charger. Be careful to
keep corrosion from coming in contact with eyes.
9. When it is necessary to remove a battery from vehicle to charge, always
remove grounded terminal from battery rst. Make sure all accessories
in the vehicle are off in order to prevent an arc.
IMPORTANT SAFETY INSTRUCTIONS
SAFETY PRECAUTIONS FOR WORKING IN THE VICINITY OF A
BATTERY
WARNING! Read and understand all Important Safety and Operating
instructions before using this charger. In addition, read and follow all battery
and vehicle manufacturer’s instructions and cautionary markings.

USER’S MANUAL PAGE 3WBC-250
10. This product is NOT intended to supply power to an extra-low-voltage
electrical system or to charge dry-cell batteries. Charging dry-cell
batteries may burst and cause injury to persons and property.
11. NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
12. If battery electrolyte contacts skin or clothing, wash immediately with
soap and water. If electrolyte enters eye, immediately ood eye with
running clean cold water for at least 15 minutes and get medical
attention immediately.
SAFETY PRECAUTIONS FOR USING THE CHARGER
1. Do NOT place the charger in the engine compartment or near moving
parts or near the battery; place as far away from them as DC cable
permits. NEVER place a charger directly above a battery being charged;
gases or uids from battery will corrode and damage charger.
2. Do NOT cover the charger while charging.
3. Do NOT expose to rain or wet conditions.
4. Connect and disconnect DC output only after setting AC cord from
electric outlet.
5. Use of an attachment not recommended or sold by the manufacturer
may result in a risk of re, electric shock or injury to persons.
6. Do not overcharge batteries by selecting the wrong charge mode.
7. To reduce the risk of damage to electric plug and cord, pull by the plug
rather than the cord when disconnecting charger.
8. To reduce risk of electric shock, unplug charger from outlet before
attempting any maintenance or cleaning.
9. Operate with caution if the charger has received direct hit of force or
been dropped. Have it checked and repaired if damaged.

10. Any repair must be carried out by the manufacturer or an authorized
repair agent in order to avoid danger.
GROUNDING AND AC POWER CORD CONNECTIONS
This battery charger is for use on a nominal 120 volt circuit. The plug must
be plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances. The plug pins must t
the receptacle (outlet). Do not use with an ungrounded system. Use of an
adapter plug is not recommended; an adaptor plug should not be used.
USING AN EXTENSION CORD
The use of an extension cord is not recommended. If you must use an
extension cord, follow these guidelines:
1. Pins sockets on the extension cord plug must be the same number,
size, and shape as those of plug on charger.
2. Ensure that the extension cord is properly wired and in good electrical
condition.
3. Wire size must be large enough for the AC ampere rating of the charger,
as specied on the next page:

DISPLAY BUTTON
Digital display LED indicator Description
Battery-voltage Voltage LED lit
When the charger is NOT charging
a battery, the display will show the
battery VOLTAGE (Voltage value /
Alternator% value / OFF in turn by
pressing DISPLAY button). When
charging BATT-06V or BATT-12V
is shown by pressing DISPLAY
button.
Battery - % Battery % LED
lit
When in charging, the digital
display shows an estimated charge
percentage of the battery con-
nected to the charger’s battery
clamps. If battery voltage is too low,
the display will show LO instead of
percentage.
Alternator - % Alternator %
LED lit
The digital display shows an
estimated output percentage of
the vehicle’s charging system
connected to the charger’s battery
clamps, compared to a properly
functioning system. The alternator
percent range is from 0% to 100%.
Readings below 0% (13.2 volts) will
read LO and readings above 100%
(14.6 volts) will read HI. If you get a
HI or LO reading, have the
electrical system checked by a
qualied technician.
