The red collet goes to the positive terminal, while the black goes to the negative. NEVER reverse the
collets when charging.
DO NOT use if wires are damaged.
Make sure the charger is kept on a level surface. DO NOT allow it to shake or vibrate while in use.
Someone should be within range of your voice or close enough to come to your aid when you work near
a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while working with a battery
acid. Acid particles or corrosion may get into eyes. Immediately flood eye with running cold water for at
least 10 minutes and get medical attention immediately.
If battery acid contacts skin or clothing, wash immediately with soap and water.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit
battery or other electrical part that may cause explosion.
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
the like to metal, causing a severe burn.
IMPORTANT SAFETY INFORMATION

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.
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.
Clean battery terminals with a mixture of baking soda and hot water. Be careful to keep corrosion from
coming in contact with eyes.
Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
Determine voltage of battery by referring to car owner’s manual and make sure that output voltage
selector switch is set at correct voltage.
Locate the charger as far away from the battery as DC cables permit.
NEVER place the charger directly above the battery being charged; gases from the battery will corrode
and damage the charger.
NEVER allow battery acid to drip on the charger when reading specic gravity or lling the battery.
DO NOT operate the charger in a closed area or restrict ventilation in any way.
DO NOT set a battery on top of the charger.
Locate the charger at least 18” above the floor.
DO NOT place the charger where rain, snow, or other moisture could drip on it.
Charger should be grounded to reduce risk of electric shock. Charger is equipped with an electric cord
having an equipment-grounding conductor and grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER – Never alter AC cord or plug provided – if it will not fit outlet, have proper outlet installed by a
qualified electrician. Improper connection can result in a risk of an electric shock.
CAUTION: Connect and disconnect DC output clips only after setting any switches with an OFF position
to off and removing AC power cord from electric outlet. Never allow clips to touch each other.
To reduce explosion risk, never connect both clips directly to the battery. When making each connection,
twist or rock clip back and forth several times to make a good connection and to reduce the risk of a clip
slipping off and creating a spark. Do not twist or rock clip on the battery after the second clip connection
is made.

PRINCIPLE OPERATION
1. Before charging, clear the storage battery and carefully check its initial voltage.
2. When charging, the current lies on the type of storage battery which is generally about 10% of the max
current of the battery.
TIME: Upon the type of storage battery, the formula is: Charging Type = Battery Current / Charging
Current
Additionally, when the charging times go by, the charging current will drop so the actual charging time
should be 1/4 times longer than theoretical. This machine can refresh one or more batteries simultaneously
as shown below. The charging time will then expand.
CHARGING A BATTERY THAT IS INSTALLED IN A VEHICLE
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than
NEGATIVE (NEG, N, –) post.
4. Determine which post of battery is grounded (connected) to the chassis. If the negative post is grounded
to the chassis (as in most vehicles), see Figure 1 and instruction 5a. If the positive post is grounded to the
chassis.
5a. For NEGATIVE GROUNDED vehicle, connect POSITIVE (Red) clip
from the battery charger to the POSITIVE (POS, P,+) ungrounded post of
the battery.
5b. For POSITIVE GROUNDED vehicle, connect the NEGATIVE (Black)
clip from the battery charger to the NEGATIVE (NEG, N, –) ungrounded
post of the battery.
7. When disconnecting charger, turn all switches with an OFF position to off, disconnect AC cord, remove
clip from vehicle chassis, and then remove clip from battery terminal.
6. Connect the remaining battery charger clip to the vehicle chassis or engine
block, as far away from the battery as possible. Do not connect the clip to
carburetor, fuel lines, or sheet metal body parts. Connect to a heavy gauge
metal part of the frame or engine block.
8. Refer to the Operating Instructions for information on setting selector switches. Be sure to refer to the
instructions for your model of charger.
OPERATION

CHARGING A BATTERY OUTSIDE OF THE VEHICLE
1. Check polarity of battery posts. POSITIVE (POS, P,+) battery post usually has a larger diameter than
NEGATIVE (NEG, N,–) post.
2. Attach a cable (not provided) to the NEGATIVE (NEG, N, –) battery post. This cable must be a minimum
of 24” long, and of a wire gauge that is no lighter than the wire gauge of the charger’s output cables (battery
cables and booster cables work well).
3. Connect POSITIVE (RED) charger clip to POSITIVE(POS, P, +) post of battery.
4. Position yourself and the free end of the cable (installed in step #2) as FAR away from the battery as
possible. FACING AWAY FROM THE BATTERY, connect the NEGATIVE (Black) charger clip to the free
end of the cable.
5. When disconnecting charger, always do so in reverse sequence of connecting procedure and break rst
connection while as far away from battery as practical.
FOR CLASS BOOSTER
1. Choose appropriate voltage (12V or 24V) and connect the charging collets.
2. Turning on switch 1 to 1, 2 or 3 is slow charge, while to 4, 5 or 6 is quick charge. Quick charging time
usually is 1 hour, controlled by a timer.
3. When starting the engine of a vehicle, rst turn on the switch 1 to “start”, wait for 2 minutes and start the
engine for 4-5 seconds. If the engine will not start for 3-4 times, wait for 10 minutes and repeat the operation
mentioned above.
