7. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than
7.1
NEGATIVE (NEG, N, –) post.
Attach at least a 24-inch long 6-gauge (AWG) insulated battery cable to NEGATIVE (NEG, N, –) battery post.
7.2
7.3 Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
Position yourself and free end of cable as far away from battery as possible – then connect NEGATIVE
7.4
(BLACK) charger clip to free end of cable.
Do not face battery when making final connection.
7.5
When disconnecting charger, always do so in reverse sequence of connecting procedure and break first
7.6
connection while as far away from battery as practical.
A marine (boat) battery must be removed and charged on shore. To charge it on board requires
7.7
equipment specially designed for marine use.
8. GROUNDING AND AC POWER CORD CONNECTIONS
This battery charger is for use on a nominal 120 volt circuit. The charger must be grounded, to reduce
8.1
the risk of electric shock. 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 fit the receptacle (outlet). Do not
use with an ungrounded system.
DANGER: Never alter the AC cord or plug provided – if it does not fit the outlet, have a proper grounded
8.2
outlet installed by a qualified electrician. An improper connection can result in a risk of an electric shock
or electrocution.
USING AN EXTENSION CORD
8.3
The use of an extension cord is not recommended. If you must use an extension cord, follow these guidelines:
• Pins on plug of extension cord must be the same number, size, and shape as those of plug on charger.
• Ensure that the extension cord is properly wired and in good electrical condition.
• Wire size must be large enough for the AC ampere rating of charger, as specified:
Length of cord (feet)
AWG* size of cord
*AWG-American Wire Gauge
9. ASSEMBLY INSTRUCTIONS
Remove all cord wraps and uncoil the cables prior to using the battery charger.

10. CONTROL PANEL

DIGITAL DISPLAY
The Digital Display gives digital indication of voltage and % of charge. It also gives Cool Down time
remaining during Engine Start. When chosen by the Display Button, the display will show the battery
Voltage or % of charge under certain conditions. First, when connected to a battery but not charging, both
options are available. When charging begins, the display will automatically change to the Voltage option,
and display On to indicate charging has started and then either 6 or 12, the voltage type of the battery
determined by the charger. If the battery voltage is low, the display will continue to show On until the voltage
type is determined. % of charge is an option only after the voltage type, 6 or 12 is determined, and also only
for the Charge rate. When the battery is fully charged, indicated by the Charged/Maintaining (green) LED lit,
the display and all other LEDs will turn off to conserve energy during Maintain mode.
DISPLAY BUTTON
Use this button to set the function of the digital display to one of the following:
Battery % – The Digital Display shows an estimated charge percentage of the battery connected to
the charger battery clamps.
Voltage – The Digital Display shows the voltage at the charger battery clamps, in DC volts.
