7.RECOIL STARTER: Manual, rope-type starter. The handle position allows easy starting from either ground level or pickup-truck level.

8.OIL DRAIN PLUG: Permits convenient draining of engine oil during maintenance. Both sides of the engine are equipped with an oil drain plug.

9.OIL FILL PLUG: Permits convenient filling of engine oil during maintenance. Both sides of the engine are equipped with an oil fill plug.

ENGINE OPERATION

WARNING

DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the POWER-ARC 4000 is 3750 RPM, no load. Do NOT adjust the governor screw on the engine. Severe personal 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 Operating and Maintenance Instructions manual that is shipped with the POWER-ARC 4000.

BEFORE STARTING THE ENGINE

CHECK AND FILL THE ENGINE OIL LEVEL:

1. Place the machine on a level surface.

2.Open the oil fill plug.

3.Fill (if necessary) until oil flows out the top of the fill plug hole.

4.Replace the fill plug and tighten securely.

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. Turn the Rotary Stop Switch to the “ON” position.

FOR A “COLD” ENGINE:

1.Open the fuel shutoff valve on the bottom of the fuel tank.

2.Place the choke lever in the “CHOKE” position.

3.Pull slightly on the recoil starter handle until resistance is felt.
