Generac Portable Products 7500EXL Extended Life Generator
Operating Automatic Idle Control
This switch is designed to greatly improve fuel
economy. When this switch is turned ON, the engine
will only am at its normal high governed engine speed
when an electrical load is connected. When an
electrical load is removed, the engine will run at a
reduced speed. With the switch
OFF, the engine will
run at the normal high engine speed. Alw ays have
the sw itch OFF w hen starting and stopping the
engine.
Battery Safety_____________________
A
A
DANGER: Storage batteries give off explosive
hydrogen gas while recharging. An explosive
mixture will remain around the battery for a
long time after it has been charged. The
slightest spark can ignite the hydrogen and
cause an explosion, which can shatter the
battery and cause blindness or other injury.
DANGER: Do Not permit smoking, open
flame, sparks or any other source of heat
around a battery. Wear protective goggles,
rubber apron and rubber gloves when working
around a battery. Battery electrolyte fluid is an
extremely caustic sulfuric acid solution that can
cause severe burns. If spill occurs flush area
with clear water immediately.
Charging a Battery
Your generator has the capability of recharging a
discharged 12 Volt automotive or utility style storage
battery.
Do Not use the unit to charge any 6 Volt
batteries. Do Not use the unit to crank an engine
having a discharged battery.
To recharge 12 Volt batteries, proceed as follow s;
• Check fluid level in all battery cells. If necessary,
add ONLY distilled water to cover separators in
battery cells.
Do Not use tap w ater.
• If the battery is equipped with vent caps, make sure
they are installed and are tight.
• If necessary, clean battery terminals.
• Connect battery charge cable connector plug to
panel receptacle identified by the words
“12-VOLTS D.C.”.
• Connect battery charge cable clamp with red handle
to the positive (+) battery terminal {Figure 7).
Figure 7 — Battery Charge Cable Connection
• Connect battery charge cable clamp with black
handle to the negative (-) battery terminal,
(Figure 7).
• Start engine. Let the engine run while battery
recharges.
• When battery has charged, shut down engine
NOTE: Use an automotive hydrometer to test battery
state of charge and condition. Follow the hydrometer
manufacturer’s instructions carefully. Generally, a
battery is considered to be at 100% state of charge
when specific gravity of its fluid (as measured by
hydrometer) is 1.260 or higher.
