GDP-5000H — OPERATING INSTRUCTIONS
Before Starting
1.Be sure to disconnect the electrical load and switch both main circuit breakers (60 and 180 Hz) to the “OFF” position prior to starting the engine.
2.Never start the engine with the main circuit breaker “ON”.
3.Check the lubricating oil level prior to starting the engine. Make sure the generator is level. The oil level must be maintained between two notches on the dipstick.
4.When there is not enough lubricating oil, fill the crankcase with high grade motor oil. Use a high quality detergent oil classified SC, SD or SE. (See Table 4 on page 13)
CAUTION:
zNEVER start the engine when the oil level is below the lower mark on the dipstick.
zCheck the fuel level on the fuel gauge. When fuel is low, fill the fuel tank with clean fresh unleaded automotive gasoline.
zIf gasoline spillage occurs, completely wipe up the spilled gasoline.
Starting
1.Open the fuel cock located below the fuel tank.The fuel starts to flow when the fuel cock is turned downward.
2.Place the idle control switch in the “ON” (up) position.
3.Close the choke. Adjust the opening of the choke valve according to operating conditions. When the engine is warm or the air temperature is high, close the choke valve halfway or open it all the way.
4.Confirm that both main circuit breakers (60 and 180 Hz) on the generator control box are in the “OFF” position.
5.Set the operation switch to the “ON” position and grasp the starting knob and slowly pull it out. The resistance becomes hardest at a certain position, corresponding to the compression point. Rewind the rope a little from that point and pull out sharply.
6.If the engine fails to start, repeat the procedure.
CAUTION:
zDO NOT pull the starter rope all the way to the end.
zDO NOT release the starter rope after pulling. Allow it to rewind as soon as possible.
Warm up
1.When the engine starts, open the choke slowly.
2.Run the engine at low speed for 3 minutes without load until the engine warms up.
3.Turn the idle control switch to the "OFF" (down) position and check the voltage by referring to the voltmeter on the control box.
CAUTION:
DO NOT change the engine speed control lever which has been set at the factory prior to shipping.
1.Check the generator for abnormal noise and smells.Then connect the load to the receptacles of the generator.
2.Switch both main circuit breakers (60 and 180 Hz) to the “ON” position and turn the idle control switch to the “ON” (down) position for normal (load) engine operation.
Operation
Check the voltage by referring to the voltmeter on the control box. When the voltmeter indicates 120 volts, 120 volts from the 120V receptacles and 240 volts from the 240V receptacle can be obtained at the same time. Refer to Figure 1, Controls and Indicators, item 7 on page 10.
Stopping the Engine
CAUTION:
NEVER stop the engine suddenly while running at high speeds.
1.Remove the load from the generator. Place the circuit breaker in the “OFF” position (See Figure. 3 on page 9). Run the engine
2.Turn the START/STOP switch to the “STOP” position.
3.Never stop the engine suddenly while running at high speed.
4.After the engine has stopped, close the fuel cock.
