Generator Operation

B-5	OPERATION	B-5

STOPPING THE ENGINE

1.Remove all welding and generator power loads and let the engine cool by running it for several minutes.

2.Stop the engine by placing the “ON/OFF” switch in the “OFF”(O) position.

3.Close the fuel shutoff valve.

WARNING

Close the fuel valve when the machine is trans- ported to prevent fuel leakage from the carbure- tor.

For long periods of storage, turn off the fuel shut- off valve and let the engine run until there is no more fuel in the line. Use a fuel additive such as Sta-Bil to minimize fuel gum deposits.

-------------------------------------------------------------

RUNNING THE ENGINE

The engine is set at the factory to run at high idle speed when not under load. You should not adjust this setting yourself.

BREAK-IN PERIOD

The engine will use a greater amount of oil during its “break-in” period. Check the oil frequently during break-in. For more details, see the MAINTENANCE section in the engine owner’s manual.

CAUTION

During break-in, the unit should be subjected to moderate loads. Before stopping the engine, remove all loads and allow the engine to cool sev- eral minutes.

-------------------------------------------------------------

LOW OIL SENSING

This engine has a built in sensor which responds to low oil level (not pressure). When activated, the syst- tem will shut the engine down. The engine will not restart untill sufficient oil is added. Check oil level fre- quently and add oil as required to the full mark on the dipstick. (DO NOT OVERFILL)

CAUTION

Be sure that any electrical equipment plugged into the generator’s AC power receptacles can with- stand a ±10% voltage and a ±4% frequency varia- tion. Some electronic devices cannot be powered by the BULLDOG™ 140. Refer to Table A.2, ELEC-

TRICAL DEVICE USE WITH THE BULLDOG™ 140, in the INSTALLATION section of this manual.

GENERAL INFORMATION

The BULLDOG™ 140 generator is rated at 4000 con- tinuous watts (5500 surge watts). It provides both 120 volt and 240 volt power. You can draw up to 20 amps from either side of the 120 volt duplex recepta- cle, but no more than 33.3 amps from both sides at once. Up to 16.7 amps can be drawn from the single 240 volt receptacle.

Electrical loads in watts are approximately calculated by multiplying the voltage rating of the load by the number of amps it draws. (This information is given on the load device nameplate.) For example, a device rated 120 volts, 2 amps will need 240 watts of power (120 x 2 = 240).

You can use Table B.1, GENERATOR POWER APPLI- CATIONS, to determine the wattage requirements of the most common types of loads you can power with the BULLDOG™ 140. Be sure to read the notes at the bottom of the table.

TO USE THE BULLDOG™ 140 AS AN AUXILIARY POWER SUPPLY:

1.Start the gasoline engine. See ENGINE OPERA- TION in this section of the manual and the engine owner’s manual.

2.Set the current control dial on the output control panel to “GENERATOR”. See Figure B.1.

3.Plug the load(s) into the appropriate 120 volt or 240 volt power receptacle.

NOTE: During welding, the maximum generator out- put for auxiliary loads is 100 watts.

NOTE: You can supply multiple loads as long as the total load does not exceed 5,500 surge watts or 4,000 Continuous watts. Be sure to start the largest loads first.
