ENGINE OPERATION

WARNING

DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the WELDANPOWER 125 is 3750 RPM, no load. Do NOT adjust the governor screw on the engine. Severe per- sonal injury and damage to the machine can result if it is operated at speeds above the maximum rated speed.

Read and understand all safety instructions included in the Briggs & Stratton Owner’s Manual that is shipped with the WELDANPOWER 125.

BEFORE STARTING THE ENGINE

CHECK AND FILL THE ENGINE OIL LEVEL:

1. Place the machine on a level sur- face.

2.Clean around the oil fill, then remove the dipstick.

3.Fill (if necessary) to full mark on the dipstick. Do NOT screw in the dipstick to check.

4.Replace the dipstick and tighten securely. For more details on checking and filling the oil, see ENGINE MAINTENANCE in the Maintenance sec- tion of this manual.

CHECK AND FILL THE ENGINE FUEL TANK:

1.Remove the fuel tank cap.

2.Fill the tank to allow approximately 1/4 inch (5 mm) of tank space for fuel expansion. DO NOT FILL THE TANK TO THE POINT OF OVERFLOW.

3.Replace the fuel tank cap and tighten securely.

NOTE: The engine will operate satisfactorily on any gasoline meant for automotive use. A mini- mum of 87 octane is recommended. DO NOT MIX OIL WITH THE GASOLINE.

Use clean, fresh, lead-free gasoline. Leaded gasoline may be used if lead-free is not available. However, lead-free gasoline leaves fewer combustion deposits and gives longer valve life. For engine protection from fuel deposits, use Briggs & Stratton Gasoline Additive, part number 5041. Purchase gasoline in quantities that will be used within 30 days, to assure freshness.

NOTE: We DO NOT recommend using gasoline that contains alcohol, such as gasohol. However, if gasoline with alcohol is used, it MUST NOT contain more than 10% Ethanol and MUST be removed from the engine during storage. DO NOT use gasoline containing Methanol.

STARTING THE ENGINE

NOTE: Remove all loads connected to the AC power receptacles before starting the gasoline engine.

FOR A “COLD” ENGINE:

1.Open the fuel shutoff valve on the bottom of the engine, below the recoil starter. Rotate the lever 1/4 turn so that it is in the vertical position and the pointer is on “O.” See Figure B.3.

2.Move the choke control to the left. See Figure B.3.
