RECEPTACLES
Your generator is equipped with duplex 120 volt receptacle
a 120 twistlock and a 120/240 volt twistlock receptacle.
The unit is also equipped with a 15 amp circuit breaker for
the duplex 120 volt receptacles, a 15 amp circuit breaker
for the 120 volt twistlock receptacle and a 15 amp circuit
breaker for the 120/240 volt twistlock receptacle. If the cir
cuit breaker trips, unplug all electrical loads from the gen
erator. Let the circuit breaker cool down. Push circuit breaker
button to reset.
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 re
ceptacle on the panel will be converted to a 120 volt recep
tacle. 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 re
ceptacle has the ability to reach the maximum 4650 surge
wattage for inductive motors that require 4650 watts or be
low 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 formulato 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 equip
ment. 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.

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.
® 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. Batteries should not be charged
when the unit is unattended.
NOTE: Dd not use t±ifi unit to chaiga any 6-volt tatteries.Do
not use the unit to crank an engine having a discharged
tstbsty.
Extension Cord
When using an appliance or tool at a considerable distance
from the generator, a 3-wire extension cord that has a 3blade 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 Sypply
Potential hazards exist when a electrical generator is con
nected 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 genera
tor and utility power. This device should be Installed by a
licensed electrician and in compliance with all local electri
cal codes.
NOTE: When installing a Double-Throw Transfer Switch,
a minimum of 10 gauge wiring must be used.
CHARGING A BATTERY
IMPORTANT: Always use safety glasses, rubber gloves
and protective clothing while charging 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.
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 posi
tion, 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.
OFF
NOTE: The idle con mmime OFF position when
operating large motor loads (Refrigerators, freezers, etc.) or
voltage sensitive electronic equipment (TV, computers, etc.)
Engine Oil
Your unit has been shipped without oil in the engine. A
bottle of SAE 30 weight oil is included in the cart.on.
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.
Connect the battery charge cable with the red handle
to the battery post indicated by POS or (+).
