Generator Operation, LOW OIL Shutdown | Campbell Hausfeld GW4500

GW4500

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.

Generator Operation

(FRONT PANEL SWITCH MUST BE SET TO GENERATOR POSITION)

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.

8.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.

Repeated cycling of the circuit breaker

indicates a problem and may cause damage to the welder / generators or load devices. Do not operate the welder / generators if repeated cycling of the circuit breaker occurs.
