4.Pull the cord rapidly.

5.If the engine does not start, open the choke slight- ly (move lever upward) and pull the starter cord rapidly again.

When the engine starts, gradually open the choke to the highest, upward position.

FOR A “HOT” ENGINE:

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

2.Place the choke lever in the highest, upward position. Closing the choke of a hot engine will flood the carbu- retor and prevent starting.

3.Pull slightly on the recoil starter handle until resis- tance is felt.

4.Pull the cord rapidly.

FOR BEST ENGINE STARTING:

Do not adjust air or fuel mixtures without following the procedures in the Briggs & Stratton Operating and Maintenance Instructions manual.

Always use fresh gasoline and be sure the filter is clean and properly maintained.

If you use an alternate fuel tank or supply, be sure to install an in-line fuel filter.

Do not pull the recoil starter with the choke in the downward position more than one time. Repeated pulls on a choked engine will flood the carburetor.

If you don’t feel resistance when you pull the recoil cord, gently hit the starter housing and/or pull the cord out to its fully extended position and wiggle it rapidly. Repeat this if necessary until the clutch engages the shaft and you feel resistance when you pull the cord.

If the engine will not start, see the TROU- BLESHOOTING section of this manual.

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 pressing downward on the piercing stop switch lever.

3.Hold the lever down firmly until the engine com- pletely stops. Otherwise, the engine may restart or sputter as it stops.

4.Close the fuel shutoff valve at the bottom of the fuel tank.

FOR BEST ENGINE STOPPING:

Do not remove the rubber spark plug boot.

Be sure the piercing point on the piercing stop switch lever firmly contacts the spark plug.

Do not apply excessive force to or bend the pierc- ing stop switch lever.

WARNING

Close the fuel valve when the machine is transported to prevent fuel leakage from the carburetor. Drain the tank before transporting the machine in a vehicle.

For long periods of storage, turn off the fuel shutoff valve (lowest, downward position) 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

Any engine will use a small amount of oil during its “break-in” period. For the gasoline engine on the POWER-ARC 4000, break-in is about 12 running hours.

Check the oil frequently during break-in. Change the oil after the first 5 hours of operation. For more details, see the MAINTENANCE section of this manu- al.

CAUTION

During break-in, subject the POWER-ARC 4000 to only moderate loads. Avoid long periods running at idle. Before stopping the engine, remove all loads and allow the engine to cool several minutes.
