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:
7.1 Check polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has a larger
diameter than NEGATIVE (NEG, N, –) post.
7.2 Attach at least a 24-inch-long 6-gauge
(AWG) insulated battery cable to
NEGATIVE (NEG, N, –) battery post.
7.3 Connect POSITIVE (RED) charger clip 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) charger clip
to free end of cable.
7.5 Do not face battery when making nal
connection.
7.6 When disconnecting charger, always do
so in reverse sequence of connecting
procedure and break rst connection
while as far away from battery as
practical.
7.7 A marine (boat) battery must be removed
and charged on shore. To charge it on
board requires equipment specially
designed for marine use.
8. GROUNDING AND AC POWER CORD CONNECTIONS
8.1 This battery charger is for use on a nominal
120 volt circuit and has a grounded plug.
The charger must be grounded, to reduce
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 t the receptacle (outlet). Do not
use with an ungrounded system.
8.2 DANGER: Never alter the AC cord or
plug provided – if it does not t the outlet,
have a proper grounded outlet installed
by a qualied electrician. An improper
connection can result in a risk of an
electric shock or electrocution.
NOTE: Pursuant to Canadian
Regulations, use of an adapter plug
is not allowed in Canada. Use of an
adapter plug in the United States is not
recommended and should not be used.
8.3 USING AN EXTENSION CORD
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
specied:
Length of cord (feet) 25 50 100 150
AWG* size of cord 16 14 14 12
*AWG-American Wire Gauge
9. ASSEMBLY INSTRUCTIONS
9.1 Remove all cord wraps and uncoil the cables prior to using the battery charger.
10. CONTROL PANEL
DIGITAL DISPLAY
The Digital Display gives a digital
indication of voltage, % of charge or
time. The display will show the battery
VOLTAGE when the charger is not
charging a battery. When it goes
into charging mode, the display will
automatically change to ON (to show
charging has started) and then show the
percent-of-charge of the battery being
charged and either 6 or 12 (the battery
voltage determined by the charger). If you
manually stop the charging process (by
pressing the START/STOP button) before
the battery is fully charged, the display will
show OFF.
NOTE: During charging, the display will
go into sleep mode and will not show the
percentage of charge or voltage of the
battery. To turn the display back on, press
any button.
LED INDICATORS
Digital Display LEDs:
% – The digital display shows an
estimated charge percentage of the battery
connected to the charger’s battery clamps.
Voltage – The digital display shows the
voltage at the charger battery clamps, in
DC volts.
