NOTE: If engine still fails to start after 3 pulls, check for
proper oil level in crankcase.This unit is equipped with a
low oil device. See engine manual.
Refer to the engine owner's manual for more
detailed starting instructions.

Connecting Electrical Loads

• Let engine stabilize and warm up for a few minutes after
starting.
• Plug in and turn on the desired 120 and/or 240 Volt AC,
single phase, 60 Hz electrical loads.
• DO NOT connect 240 Volt loads to the 120 Volt duplex
receptacles.
• DO NOT connect 3–phase loads to the generator.
• DO NOT connect 50 Hz loads to the generator.
• DO NOT OVERLOAD THE GENERATOR. See
"Don't Overload the Generator" on page 11.

Stopping the Engine

• Unplug all electrical loads from generator panel
receptacles. NEVER start or stop engine with electrical
devices plugged in and turned ON.
• Let engine run at no-load for several minutes to stabilize
the internal temperatures of engine and generator.
• Move the engine switch to "Off" position.
• Move the fuel valve to the "Off" position.

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.
PowerBoss 4,500 Watt Contractor Generator
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 7).
Figure 7 — Battery Connections
• 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.

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.
