7. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE

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

8. GROUNDING AND AC POWER CORD CONNECTIONS

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 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 outlet installed
by a qualified 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.

9. ASSEMBLY INSTRUCTIONS

9.1 Remove all cord wraps and uncoil the cables prior to using the battery charger.

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 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.
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
specified:
Length of cord (feet)
AWG* size of cord
*AWG-American Wire Gauge
RATE SELECTION
Use this button to select one of the following:
• 6<>2A CHARGE/MAINTAIN –
For charging small and large batteries. Not
recommended for industrial applications.
The charger will automatically adjust the
charging current, based on battery size,
in order to charge the battery completely,
efficiently and safely.
• 10A BOOST – This setting may be
used for a quick boost, prior to using
the engine start setting. Do not use this
setting to charge your battery.
• 50A ENGINE START – Provides
additional amps for cranking an engine
with a weak or run-down battery. Always
use in combination with a battery.
