Operating Automatic Idle Control
This control is designed to greatly improve fuel economy.
When this switch is turned “ON”, the engine will only
run at its normal high governed engine speed when an
electrical load is connected. When the electrical load is
removed, the engine will run at a reduced speed. With
the switch “Off ”, the engine will run constantly at high
engine speed. Always have the switch “Off ” when
starting and stopping the engine.
Battery Safety
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. Such an
explosion can shatter the battery and cause
blindness or other serious 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 generator to charge any 6 Volt batteries. Do Not
use the generator to crank an engine having a discharged
battery.
To recharge 12 Volt batteries, proceed as follows:
• Check fluid level in all battery cells. If necessary, add
ONLY distilled water to each cell. Do Not use tap
water.
• 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 10).
• Connect battery charge cable clamp with black handle
to the negative (–) battery terminal (Figure 10).
• 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.
