2. PERSONAL PRECAUTIONS

2.1 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 and clothing protection. Avoid
touching eyes while working near battery.

2.2 If battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters eye,
immediately flush eye with running cold water for at
least 10 minutes and get medical attention immediately.

2.3 NEVER smoke or allow a spark or flame in vicinity of

battery or engine.

2.4 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.

2.5 When working with a lead-acid battery, remove
personal metal items such as rings, bracelets,
necklaces, watches, etc. 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.

2.6 Use charger for charging a Lead-Acid Battery only.
It is not intended to supply power to a low voltage
electrical system other than in a starter-motor
application. Do not use battery charger for charging
dry-cell batteries that are commonly used with home
appliances. These batteries may burst and cause injury
to persons and damage to property.

2.7 NEVER charge a frozen battery.

2.8 The charger design for charging 18 Ah. Lead Acid
batteries maximum.

3. PREPARING TO CHARGE

3.1 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.

3.2 Clean battery terminals. Be careful to keep corrosion
from coming into contact with eyes. Add distilled water
in each cell until battery acid reaches level specified by
battery manufacturer. This helps purge excessive gas
from cells. Do not overfill. For a battery without caps,
carefully follow manufacturer's recharging instructions.

3.3 Study all battery manufacturer's specific precautions
such as removing or not removing cell caps while
charging and recommended rates of charge.

3.4 Determine voltage of battery by contacting battery
manufacturer and make sure it matches output rating of
battery charger.

4. CHARGER LOCATION

4.1 Locate charger as far away from battery as dc cables
permit.

4.2 Never place charger directly above battery being
charged; gases from battery will corrode and damage
charger.

4.3 Never allow battery acid to drip on charger when
reading gravity or filling battery.

4.4 Do not operate charger in a closed-in area or restrict
ventilation in any way.

4.5 Do not set a battery on top of charger.

5. DC CONNECTION PRECAUTIONS

5.1 Connect and disconnect DC output terminals only after
removing charger from AC outlet.

5.2 Never allow DC output terminals to touch each other.

5.3 If problems arise connecting the output leads, solicit the
aid of your Dealer from whom you purchased this
product or the charger manufacturer for finding a
suitable connection device for your application.

6. FOLLOW THESE STEPS WHEN BATTERY IS
INSTALLED IN VEHICLE. A SPARK NEAR BATTERY
MAY CAUSE BATTERY EXPLOSION. TO REDUCE
RISK OF A SPARK NEAR BATTERY:

6.1 Position AC and DC cords to reduce risk of damage by
hood, door or moving engine part.

6.2 Stay clear of fan blades, belts, pulleys, and any other
parts that can cause injury to persons.

6.3 Check polarity of battery posts POSITIVE (POS.,P,+)
post usually has larger diameter than NEGATIVE -
(NEG.,N,-).

6.4 Determine which post of battery is grounded
(connected) to chassis. If negative post is grounded (as
in most vehicles), see paragraph 6.5. If positive post is
grounded, see paragraph 6.6.

6.5 For negative-grounded vehicle, first connect POSITIVE
(RED) clip from charger to POSITIVE (POS.,P,+)
ungrounded post of battery. Then connect NEGATIVE
(BLACK) terminal to vehicle chassis or engine block
away from battery.

6.6 For positive-grounded vehicle, connect NEGATIVE
(BLACK) clip from charger to NEGATIVE (NEG.,N,-)
ungrounded post of battery. Connect POSITIVE (RED)
clip to vehicle chassis or engine block away from
battery keeping the battery terminal well-removed
therefrom.

6.7 Do not connect any charger clips to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy
gauge metal part of the frame or engine block.

6.8 When disconnecting charger, turn switches (if supplied)
to off, disconnect charger from AC power, remove clip
from vehicle chassis, and then remove clip from battery
terminal. See operating instructions for length of charge
information.

6.9 Made sure the 6V 12V selection switch position is
correct. Do not select 12V position to charge the 6V
Battery. Do not select 6V position to charge the 12V
Battery.

7. FOLLOW THESE STEPS WHEN BATTERY IS
OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY
MAY CAUSE BATTERY EXPLOSION. TO REDUCE
RISK OF A SPARK NEAR BATTERY:

7.1 Check polarity of battery posts. POSITIVE (POS.,P,+)
battery post usually has a larger diameter than
NEGATIVE (NEG.,N,-) post. Some batteries are
equipped with 'Wing- Nut' terminals allowing for easy
placement of the terminals to these posts.

7.2 Attach at least a 24-inch long 18-gauge (AWG)
insulated battery cable to NEGATIVE (NEG.,N,-) battery
post.

7.3 Connect POSITIVE (RED) charger terminal to
POSITIVE (POS.,P,+) post of battery.

7.4 Position yourself and free end of cable as far away
from battery as possible - then connect NEGATIVE
(BLACK) terminal to free end of cable.

7.5 Do not face battery when making final connection.

7.6 When disconnecting charger, always do so in reverse
sequence of connecting procedure and break first

on shore. To charge it on board requires equipment

specially designed for marine use.

connection while as far away from battery as practical

7.7 A marine (boat) battery must be removed and charged

7.8 Switch select to 6V position for charge 6V Battery.

7.9 Switch select to 12V position for charge 12V Battery.

8. OPERATING INSTRUCTIONS

Once the connection instructions have been followed,
the Light Emitting Diode (L.E.D.) lights when A.C.
Power is present. Red Light present at 12V charge
mode, Yellow Light present at 6V charge mode, The

Yellow L.E.D. lights to indicate ‘ Charging Mode’ and
that a proper connection to the battery has been made.

The battery charges to approximately 14.4Vdc at 12V
switch selection, charges to 7.2Vdc at 6V switch

selection, and then transitions into the‘ Float Mode’
where the White L.E.D. turns GREEN and the

regulating voltage reduces to a lower level. The Float
Mode allows the charger to effectively be left connected
to your batteries, over the course of a season, without
overcharging your batteries, and maintains the full
charge on your batteries. A regular, periodic check on
your charging system, if left unattended and powered,
is still recommended (just as you would with any

electrical appliance). The ‘ Float Mode ’ also
contains a special charging waveform, that pulses

power into your batteries, and helps to peak the power
into your battery. Also, while in this mode, if the charger
senses a load that has activated, the charger recycles

to the ‘ Charging Mode’ to start charging again, up
to the 14.4Vdc level at 12V switch selection, 7.2V level

at 6V switch selection

9. PROTECTION DEVICES AND MEASURES

9.1 OVERLOAD PROTECTION

The charger employs the use of a ‘ Solid State Circuit

Interrupter’ that opens under severe overload. This
condition may occur if attempting to charge any

severely discharged or heavily sulfated battery. Once
the Interrupter opens, the charger will stop charging for
a short period and then resume charging automatically
and the yellow. L.E.D. will be OFF, until resume
charging. Overloading could be due to an external load,
remove the load condition prior to attempting to
recharge the battery.

9.2 REVERSE BATTERY / OVERLOAD CONDITION.
The charger has reverse battery and short circuit
protection. If a reverse battery condition exists (White
L.E.D. will turn RED, only, while output leads are
connected backwards), simply unplug charger from AC
power and properly remake the connections as
described in this manual.

10. MAINTENANCE

Store in clean, dry place. Occasionally clean the case
and cords with a dry cloth.
