Installed by a qualified electrician. Improper connection can result in a risk of an electric
shock.
This battery charger is for use on a nominal 117-volt circuit, and has a grounding plug
that looks like the plug illustrated In sketch A In Figure 1. A temporary adapter, which looks
like the adapter illustrated in sketches B and C, may be used to connect this plug to a two-
pole receptacle as shown In sketch B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet can be installed
by a qualified electrician.
DANGER - Before using adapter as illustrated, be certain that center screw of outlet plate
is grounded. The green colored rigid ear or lug extending from adapter must be connected
to a properly grounded outlet - make certain it is grounded. If necessary, replace original
outlet cover plate screw with a longer screw that will secure adapter ear or lug to outlet
cover plate and make ground connection to grounded outlet.
Use of an adapter is not allowed in Canada. It a grounding type receptacle is not available,
do not use this appliance until the proper outlet is installed by a qualified electrician.

J. OPERATION INSTRUCTIONS
This battery charger is equipped with a self-resetting circuit breaker. This device protects
the charger from temporary overloads. In the event of an overload, the circuit breaker
will trip open, and after a short cooling off period will reset automatically. This process
is known as cycling and can be recognized by an audible clicking sound.
K. OUTPUT VOLTAGE SELECTOR SWITCH
Set output voltage selector switch to match voltage of battery to be charged. For models
without voltage selector switch make sure voltage of battery matches that of the charger.
Battery charger models having a voltage selector switch are for charging a 6 or a 12 Volt
battery. Those having no voltage switch are intended for charging a 12 Volt battery only.
