GENERATOR CAPACmTY
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 should
always be calculated when matching a generators
wattage capacity to the appliance or tool.
There are two types of electrical appliances that
can be powered by your generator:
A. Items such as radios, light bulbs, television
sets, and microwaves have a "resistive load".
Starting wattage and running wattage are the
same.
B. Items such as refrigerators, air compressors,
washer, dryer, and hand tools that use an
electrical motor have an "inductive load".
Inductive load appliances and tools require
approximately 2 to 4 times the listed 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: Some inductive appliances and tools wiii list
on the motor name plate, the starting and running
voltage and amperage requirements. Use the follow-
ing formula to convert voltage and amperage to
wattage: (Volts X Amp = Watts}
* Always start your largest electric motor first, and
then plug in other items, one at a time.
The guide 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 from
a generator:
o Use of extension cords directly from the genera-
tor 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 8-dot recep-
tacle that accepts the tool's plug MUST be used in
order to reduce the risk of electrical shock. 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.
An extension cord that is hot
to the touch is overmoaded.
Repair or replace damaged extension cords
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.

CARBURETOR
The carburetor of your generator is pre-set at the fac-
tory. The carburetor shouid not be tampered with. If your
generator is used at an aititude in excess of 4000 feet
performance may be affected. If so consult with your
nearest Craftsman Service Center regarding high altitude

If you are going to store your generator for more than
30 days, use the following information as a guide to
prepare the generator for storage.
Engine Preparation
* Add fuel stabilizer to fuel tank to minimize the
formation of fuel gum deposits during storage.
Run engine at bast 10 minutes after adding
stabilizer to allow it to enter the fuel system.
Disconnect the spark plug wire and remove the
spark plug.
Add one teaspoon of oil through the spark plug
hob.
Place rag over spark plug hob and pull the recoil a
few times to lubricate the combustion chamber.
Replace the spark plug, but do not connect the
spark plug wire.
NOTE-" If a fuel stabilizer is not used, all gasoline must
be drained from the tank and carburetor to prevent gum
deposits from forming on these parts and causing pos-
sible malfunction of the engine.
