RBSK OF ELECTROCUTBON AND FBRE .(cont'd}
HAZARD
Operation of generator in rain, wet,
icy, or flooded conditions.
Use of worn damaged, undersized
or ungrounded extension cords.
Piacing generator on or against
higHy conductive surface, such as
a steei waikway or metai roof.
WHAT COULD HAPPEN
Water is an excellent conductor of ebc-
tricity! W/ater which comes in contact
with electrically charged components
can transmit electricity to the frame and
other surfaces, resulting in electrical
shock to anyone contacting them.
Contact with worn or damaged exten-
sion cords could result in electrocution.
Use of undersize extension cords could
result in overheating of the wires or at-
tached items, resulting in fire.
Use of ungrounded cordsets could pre-
vent operation of circuit breakers and
result in electrical shock.
Accidental leakage of electrical current
could charge conductive surfaces in
contact with the generator.
HOW TO PREVENT iT
Operate generator in a clean, dry,
well ventilated area. Make sure
hands are dry before touching unit.
Inspect extension cords before use
and replace with new cord if re-
quired.
Use proper size (wire gauge) cordset
for application see chart in the As-
sembly section of this manual
Always use a cordset having a
grounding wire with an appropriate
grounding plug. DO NOT use an
ungrounded plug.
Place generator on low conductiv-
ity surface such as a concrete
slab.
Improper connection of items to
generator.
Exceeding the load capacity of the gen-
erator by attaching too many items, or
items with very high load ratings to it
could result in overheating of some
items or their attachment wiring result-
ing in fire or electrical shock.
Operation of unit when damaged, or
with guards or paneb removed.
Attempting to use the unit when it has
been damaged, or when it is not func-
tioning normally could result in fire or
electrocution.
Removal of guarding could expose
electrically charged components and
result in electrocution.
MGP670040 4 -- ENG
ALWAYS operate generator a
minimum of six feet from any
conductive surface.
Read the load rating chart and in-
structions in the Wattage Calcula-
tion section. Make sure that the
summation of electrical loads for all
attachments does not exceed the
load rating of the generator.
Do not operate generator with me-
chanical or electrical problem. Have
unit repaired by an Authorized Ser-
vice Center.
Do not operate generator with pro-
tective guarding removed.
READ AND UNDERSTAND ALL WARNINGS BEFORE
ATTEMPTBNG TO OPERATE GENERATOR°
RiSK OF FiRE
HAZARD
Attempting to fill the fuel tank while
the engine is running.
Sparks, fire, hot objects
Improper storage of fuel
Inadequate ventilation for genera-
tor
Tampering with factory set engine
speed settings.
WHAT COULD HAPPEN
Gasoline and gasoline vapors can
become ignited by coming in contact
with hot components such as the
muffler, engine exhaust gases, or from
an electrical spark.
Cigarettes, sparks, fires, or other hot
objects can cause gasoline or gaso-
line vapors to ignite.
Improperly stored fuel could lead to
accidental ignition. Fuel improperly
secured could get into the hands of
children or other unqualified persons.
Materials placed against or near the
generator or operating the generator
in areas where the temperature
exceeds 104 ° R ambient (such as
storage rooms or garages) can
interfere with its proper ventilation
features causing overheating and
possible ignition of the materials or
buildings.
Engine speed has been factory set to
provide safe operation. Tampering
with the engine speed adjustment
could result in overheating of attach-
ments and could cause a fire.
HOW TO PREVENT iT
Turn engine off and allow it to cool
before adding fuel to the tank.
Equip area of operation with a fire
extinguisher certified to handle
gasoline or fuel fires.
Add fuei to tank in weii ventilated
area. Make sure there are no
sources of ignition near the
generator.
Store fuel in a OSHA approved
container designed to hold gaso-
line. Store container in secure
location to prevent use by others.
Operate generator in a clean, dry,
weii ventilated area a minimum of
four feet from any building, object
or waii. DO NOT OPERATE UNiT
iNDOORS OR iN ANY CON=
FINED AREA.
Never attempt to "speed=up" the
engine to obtain more perfor-
mance. Both the output voltage
and frequency wiil be thrown out
of standard by this practice,
endangering attachments and the
user.
Overfilling the fuel tank -
fuel spillage.
Spilled fuel and its vapors can be-
come ignited from hot surfaces or
sparks.
5 -- ENG lvlGP670040
Use care in filling the tank to avoid
spilling fuel. Make sure fuel cap is
secured tightly and check engine
for fuel leaks before starting
engine. Move generator away
from refueling area or any spillage
before starting engine. Allow for
fuel expansion. Keep maximum
fuel level 1Ainch below the tip of
the fuel tank. Never refuel with the

LOW OIL SHUTDOWN
Your Craftsman generator engine is equipped with Low
Oil Shutdown. Low Oil Shutdown is a safety device
designed to protect your engine from damage in the
event the oil [eve[ in the crankcase is low.
If while the engine is running, the oil gets low, it wi[[
automatically shut itself down and wi[[ not restart until
the oil is added. If the oil is low before start-up, the
generator wi[[ not start until oil is added.
NOTE: The Low Oil Shutdown mechanism is very sensi-
tive. You must fi[[ the engine to the fuji mark on the dip-
stick to inactivate this safety device.

GENERATOR CAPACITY
Exceeding the rated capacity of your generator can
result in serious damage to your generator and con-
nected 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 too[.
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 watt-
age to be used.
