Stopping the Engine

• Unplug all electrical loads from generator panel

receptacles. Never start or stop engine with electrical
devices plugged in and turned on.

• Put the idle control switch in the “Off” position.

• Let engine run at no–load for 30 seconds to stabilize the

internal temperatures of engine and generator.

• Move run/stop switch to “Stop”.

• Close the fuel shut–off valve.

Operating Automatic Idle Control

This switch 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 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. Always have the switch off when starting and
stopping the engine.

Charging a Battery

WARNING!

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, resulting in
blindness or other serious injury.

WARNING!

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.

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 follows:

• Check fluid level in all battery cells. If necessary, add

ONLY distilled water to cover separators in battery cells.
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 9).

• Connect battery charge cable clamp with black handle

to the negative (–) battery terminal (Figure 9).

• 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.
