Generator Operation - Campbell Hausfeld GW4502 Operating Instructions And Parts Manual

Pre-Operation (Continued)
LOW OIL SHUTDOWN
A low oil shutdown switch is provided
to protect the engine and welder /
generators on most extended run
models. When engine oil level drops
too low for proper engine operation,
the low oil shutdown switch causes the
engine to shut off. If oil level is low
when attempting to start the welder /
generators engine, the low oil level
shutdown switch prevents the engine
from starting. If engine does not start,
check oil level.
NOTE: It is important to keep the
welder / generator unit on a level
surface. The oil level shutdown switch
can prevent the engine from starting
even if oil level is sufficient, when the
welder / generators unit is placed on an
uneven surface.

LOAD DEVICES
1. All load devices and extension cords
should use three prong terminals.
Refer to Table 2 for extension cord
and cable size requirements.
2. Allow the engine to run for 2-
3 minutes before applying any
electrical loads.
3. The 120 volt receptacles are rated
for 20 amps and may be used in any
combination of 120 volt loads and
also with 240 volt loads through
the 240 volt receptacles.
The 240 volt receptacles, found on
some welder / generators, are rated
for 20 amps and may be used in any

combination of 240 volt loads and
also with 120 volt loads through
the 120 volt receptacles.
The 120/240 volt twist lock
receptacle, found on some welder /
generators, is rated for 20 amps and
may be used in any combination of
120 volt and 240 volt loads.
4. Individual receptacles should not
be loaded beyond the amperage
rating.
5. Total combined load through any
combination of receptacle must
not exceed the rated load limits of
the welder / generator. Refer to the
identification plate on the welder /
generators for amp and wattage
specifications.
6. Always shut off and remove loads
before starting or shutting off the
welder / generator engine.
7. When plugging multiple electrical
load devices into the welder /
generators receptacles, be sure to
connect and activate the highest
power draw item first. Allow
the welder / generator engine to
stabilize, then connect and activate
the next highest power draw
device. The smallest power draw
device should be connected to the
receptacle and activated last.
NOTE: Power draw can be calculated
by multiplying volts and amps. The
resulting number is wattage.
Never exceed the posted maximum
wattage for the welder / generator
or any individual receptacle. Refer to
owner's manuals and product tags to
determine the wattage of all electrical
load devices.

If actual watt ratings are not available,
the Power Usage Chart, see Table 1, may
be used as a general guideline.
Remember that devices which generate
heat during operation such as heaters,
incandescent light bulbs, motors and
hair dryers have a higher power draw
than devices which generate little heat
during operation such as florescent
bulbs, radios, and clocks.
Long power cords and extension cords
also draw additional power. Keep cords
at minimum possible length.
Refer to Table 2 for maximum limits for
lengths of extension cords.

Circuit protection is provided by a
circuit breaker. The circuit breaker
opens when the welder / generator
load exceeds its maximum capacity
or a short circuit occurs. If the
circuit breaker opens, perform the
following procedures to correct the
problem:
a. Shut off and disconnect all
electrical loads.
b. Attempt to determine the cause
of the electrical problem -
overloading or short circuit.
c. Do not use any devices that have
short circuits. Avoid overloading
the welder / generator.
d. Press the circuit breaker
pushbutton to reset the circuit
breaker.
