  • 1) Strictly follow the Oil dipstick to add in engine oil with the oil gauge shall not exceed the upper limit or below the lower limit of the dipstick scale.
  • 2) Engine oil should be changed in the 1st time of 20 hours after new machine running, 2nd change will be 60 hours after and later, each 250 hours you need to change the engine oil.

You may find in each generator a steel data plate with information in Chinese, here comes the English information as below:


  • 1) Generator should be kept clean to avoid any dirt, water droplets, metal fragments or other debris intrusion;
  • 2) Generator MUST BE GOOD GROUNDED;
  • 3) Generator power output cable should be sufficient with enough cross-sectional area and good connected with the appliance;
  • 4) DO NOT run the generator at a overload situation;
  • 5) ALWAYS balance the phase loading level of triple phases;
  • 6) Rated output data on this plate is for THREE-PHASE generator ONLY, DO NOT use it as single-phase rated output;
  • 7) Check regularly the generator brush and lubrication of the bearing chamber to avoid unexpected abrasion;
  • 8) ALWAYS make the wire connecting in strict accordance with the wiring guidance.

Procedure of generator start up

  • 1) Disconnect the output air switch;
  • 2) Starting up the generator until the runner speed up to no-load level;
  • 3) Adjust the AVR (automatic voltage regulator) to prospective appliance voltage value;
  • 4) Connect the output air switch and then load the appliances into the generating system one by one;

Procedure of generator stop off

  • 1) Stop off all appliances to remove all electric loading;
  • 2) Disconnect the output air switch;
  • 3) Stop the generator.
