FULL POWER SWITCH
Your Craftsman generator has a full power switch on the
control panel. This switch has two positions: 120 VOLT
ONLY, and 120/240 VOLT.
120 Position
When placed in the 120 position, (Shown below) every
receptacle on the panel will be converted to a 120 volt
receptacle. 240-volt power is not available. This position
allows full capacity of the generator to be received by
using all 120-volt receptacles. While in the 120 position,
each receptacle has the ability to reach the maximum 7500
surge wattage for inductive motors that require 7500 watts
or below to start.
GENERATOR CAPACITY
Exceeding the rated capacity of your generator can
result in serious damage to your generator and connected electrical devices. You should observe the
following to prevent overloading the unit:
• Starting and running wattage requirements must be
calculated to match your generator wattage capacity.
• Resistive load appliances such as light bulbs, TV’s
and microwaves, have the same starting and running
wattage. The wattage used for calculating the capacity
can usually be found on each of these appliances.
Some inductive appliances and tools will list on the motor
name plate, the starting and running voltage and amperage requirements. Use the following formula to convert
voltage and amperage to wattage:
(Volts X Amp = Watts)
Inductive load appliances and tools such as refrigerators, air compressors and washers require approximately
2 to 4 times the listed running wattage for starting the
equipment. This initial load only lasts for a few seconds
on start-up but is very important when figuring your total
wattage to be used.
NOTE: Always start your largest electric motor first, and
then plug in other items, one at a time.
The guide below is provided to assist you in determining
the appliances and tools that can be ran with the wattage capacity of your generator.

120/240V
120/240 Position
When in the 120/240 position, (Shown Below) only half of
the 5800 watts can be received when using the 120-volt
receptacles and the 120/240-volt twistlock receptacle will
be converted to allow the full 5800 watts to be received
from this one receptacle. Also in this position, the 120volt receptacles will only reach a maximum of 3750 surge
watts.

OBTAINING ELECTRICITY FROM
GENERATOR
There are basically two ways to obtain electricity form a
generator:
• Use of extension cords directly form the generator
to the appliance, lights, tools, etc.
• Use of a double-throw transfer switch installed
directly to the main electrical supply outside of the
house.
Extension Cord
When using an appliance or tool at a considerable distance from the generator, a 3-wire extension cord that has
a 3-blade grounding plug and 3-slot receptacle that accepts the tool’s plug should be used. A cord of adequate
size must be used. A minimum of 12 gauge wire size with
at least a 20 amp draw can be used. When amperage
exceeds 20 amps a 10 gauge wire size should be used.
Connecting Generator To Main Electrical
Supply
Potential hazards exist when a electrical generator is connected to the main electrical supply coming into the house.
It is at that point that the generator could feed back into
the utility company’s system causing possible electrocution of workers who are repairing electrical lines. To avoid
back feeding of electricity into utility systems, a double-
throw transfer switch should be installed between the
generator and utility power. This device should be installed
by a licensed electrician and in compliance with all local
electrical codes.
NOTE: When installing a Double-Throw Transfer Switch,
a minimum of 10 gauge wiring must be used.
• Start the engine. Let it run while the battery charges.
• When the battery is fully charged, stop the engine
and disconnect the battery charge cables from the
panel and battery.
NOTE: Do not use the unit to charge any 6-
volt batteries.Do not use the unit to crank an engine having
a discharged battery.
BEFORE STARTING ENGINE
CAUTION: Always check engine oil level before
every start. Running engine low of oil or out of oil
could result in serious damage to the engine.
Automatic Idle Control
The automatic idle control switch, when in the ON
position, allows the engine to run at lower speed when
there is no load on the generator. This will lower the
engine noise, save on fuel consumption and engine life.
When in the OFF position the engine will run at 3600
RPM’s continuous with or without a load.
ON OFF
IDLE CONTROL
NOTE: The idle control must be in the OFF position when
operating large motor loads (Refrigerators, freezers, etc.)
or voltage sensitive electronic equipment (TV, computers,
etc.)
CHARGING A BATTERY
Your generator has the capability of recharging a 12-volt
storage or automotive battery. To recharge a 12-volt
battery, proceed as follows:
• First, check the fluid level in all of the battery cells.
Add distilled water if necessary. Do not use tap
water.
• Clean battery posts if necessary.
• Connect battery charge cables to panel receptacle.
• Connect the battery charge cable with the red
handle to the battery post indicated by POS or (+).
• Connect the battery charge cable with the black
handle to the battery post indicated by NEG or (-).
Engine Oil
Your unit has been shipped without oil in the engine. A
bottle of SAE 30 weight oil is included in the carton.
Remove oil dip stick located on the side of engine. The
oil dip stick is clearly marked with a line that tells you
when unit has enough oil. Do not fill above this point.
Pour slowly.
CLEAN
DIPSTICK
NOTE: When adding oil to the engine crankcase in the
future, use a high quality detergent oil classified “For
Service SF, SG, SH” rated SAE 30 weight. Use no
special additives. Select the oil’s viscosity grade according to you expected operating temperatures.
11 — ENG
Air cooled engines run hotter than automotive engines.
The use of multi-viscosity oil such as (10W-30, etc.) in
ambient temperatures above 40°F (4°C) will result in higher
than normal oil consumption. If multi-viscosity oil is used,
check the oil level more frequently to prevent any posssible
engine damage due to lack or lubrication.
Use of SAE30 oil below 40°F (4°C) will result in hard starting and possible engine damage due to inadequate lubrication.
Low Oil Shutdown
Your Craftsman generator engine is equipped with Low
Oil Shutdown. Low Oil Shutdown is a safetydevice
designed to protect your engine from damage in the
event the oil level in the crankcase is low.
If while the engine is running, the oil gets low, it will
automatically shut itself down and will not restart until
the oil is added. If the oil is low before start-up, the
generator will not start until oil is added.
To Start Your Generator
CAUTION: Never run engine indoors or in enclosed,
poor ventilated areas, engine exhaust contains carbon monoxide, an ordorless and deadly gas.
Make sure the fuel shutoff valve is turned to the open position.
OPEN
• Remove gas cap
• Add unleaded gasoline, slowly, to fuel tank.
• Do not overfill.
• On the engine there is a choke/run lever. Place lever
to the choke position.
CLOSE
NOTE: The Low Oil Shutdown mechanism is very
sensitive. You must fill the engine to the full mark on the
dipstick to inactivate this safety device.
Gasoline
Your generator engine is 4 cycle. Use unleaded fuel
only. Never mix oil with gasoline.
CAUTION: Never fill fuel tank completely. Fill tank
to 1/2" below the bottom of the filler neck to provide
space for fuel expansion. Wipe any fuel spillage from
engine and equipment before starting engine.
WARNING: Never fill fuel tank indoors. Never fill fuel
tank when engine is running or hot. Do not smoke
when filling fuel tank.
Use clean, fresh, regular unleaded gasoline with a minimum of 85 octane. Do not mix oil with gasoline. If unleaded fuel is not available, leaded fuel may be used.
CHOKE
