so could result in damage to equipment plugged into the unit and possible injury to the individual.

All engines have a tendency to slow down when a load is applied. When the electrical load is connected to the generator, the engine is more heavily loaded, and as a result the speed drops slightly. This slight decrease in speed, together with the voltage drop within the generator itself, results in a slightly lower voltage when the generator is loaded to its full capacity than when it is running with no load. The slight variation has no appreciable effect in the operation of motors, lights and most appliances. Electronic equipment and clocks will be affected if correct RPM is not maintained.

Output voltage should be checked periodically to ensure continued proper operation of the generating plant and appliances, it can be checked with a portable meter. Frequency can be checked by using an electric clock with a sweep second hand. Timed against a wrist watch or a stop watch the clock should be correct within +/- 2 seconds per minute. All speed setting adjustments should be done by a qualified technician.

BEFORE STARTING

1.Make sure the generator is positioned on a firm level surface.

2.Check the crankcase for oil and maintained at a proper level.

3.Check fuel level and fill tank 7/8 full with diesel fuel. Never fill fuel tank completely to the top. Always wipe up and remove any spilled diesel fuel.

4.Make sure that the exhaust fumes are directed away from people.

ELECTRIC START OF ENGINE

1.Disconnect all loads to generator.

2.Turn gas line valve to ON position.

3.Turn the ignition key to the START position.

4.If the engine does not start after 10 seconds,

wait 15 seconds before attempting to start

again.

5.If the engine will not start consult the trouble shooting table (page 10).

MANUAL START OF ENGINE

1.Disconnect all loads to generator.

2.Turn fuel line valve to ON position.

3.Turn the ignition key to the RUN position.

4.Grasp the recoil handle and pull until a

strong

resistance is felt.

5.Let the recoil handle return to the initial position.

6.Push down the decompression lever. The

lever

is located on top of the engine and is colored RED.

7.Pull out the recoil handle briskly with both hands.

8.If the engine will not start consult the trouble shooting table (page 10).

ENGINE SHUTDOWN

1.Disconnect all loads from generator.

2.Turn the ignition key to the OFF position.

3.Turn the fuel valve to the OFF position.

ENGINE CARE

Refer to your Yanmar Owner’s Manual for proper care and maintenance.

Refer to your Yanmar Owners manual for fuel and oil information.

IMPORTANT: It is possible that the fuel line will need to be bled the first time the fuel tank is filled.

NOTE: When changing the oil on a hot engine, the oil might overshoot the oil drain hole on the
