4.Pull the cord rapidly.

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

When the engine starts, gradually open the choke to the “RUN” position. To open the choke fully, requires an engine warm-up period of several seconds to several minutes depending on the temprature. After starting the engine, first open the choke (toward RUN) until the engine just begins to run smoothly. Then open the choke in small steps, allowing the engine to accept small changes in speed and load, until the choke is fully open (in RUN). During engine warm-up the equiptment can be operated.

FOR A “HOT” ENGINE:

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 turning the Rotary Stop Switch on top of the engine to the “OFF” position.

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.

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 carbure- tor 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:

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

Close the fuel valve when the machine is trans- ported to prevent fuel leakage from the carbure- tor. Drain the tank before transporting the machine in a vehicle.

For long periods of storage, turn off the fuel shut- off 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

The engine will use a greater amount of oil during its “break-in” period. The 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 the engine owner’s manual.

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 min- utes.
