GASOLINE ENGINE CONTROLS
See Figure B.2 for the location of the following fea- tures.
1.FUEL SHUTOFF VALVE: Stops the flow of gasoline from the fuel tank to the carburetor. Should be closed whenever you are finished using the WEL- DANPOWER 125. Must be opened before you start the engine.
2.FUEL TANK AND CAP: Holds 1.6 gallon (6.0 liters) of unleaded gasoline. Contains a 50 micron fuel filter molded at the outlet port.
NOTE: If you use any other alternate fuel tank or supply, be sure to use a recommended in- line fuel filter.
3.MUFFLER: Reduces engine noise output. Does not serve as a spark arrester. See SPARK ARRESTER in the Installation section of this man- ual.
4.ROCKER STOP SWITCH/OIL GARD® LIGHT: Stops the engine by grounding the ignition circuit. Glows red when engine oil level is low.
5.AIR CLEANER: Filters intake air to the carburetor. See ENGINE MAINTENANCE in the Maintenance section of this manual for details about the specif- ic type of air cleaner to use.
6.IDLER CONTROL SWITCH: (Not shown. See item 10, Figure B.1.) Adjusts the running speed of the engine. The switch has two positions, HIGH and AUTO. In HIGH, the engine runs continuously at high idle. In AUTO, the idler control works as follows:
Welding: The engine accelerates to high speed when the electrode touches the work and strikes a welding arc. The engine returns to low idle approximately 12 seconds after welding stops, as long as no auxiliary power is being drawn.
Auxiliary Power: The engine accelerates to high speed when power is drawn at the receptacles for lights or tools. The engine returns to low idle approximately 12 seconds after demand for auxil- iary power stops.
