1、 Preparation before start-up of natural gas generator set: check and adjust the condition of the whole unit before start-up. The connection and fixation of each component must be correct. The cooling water system of the engine and the electric starting system are connected stably without dripping and loosening. The switch is flexible. The lubrication system is in good condition. The fuel supply system and ignition system are confirmed to be normal. Otherwise, it can be started only after maintenance and adjustment are correct 。

二、啟動(dòng)后的怠速運(yùn)行：準(zhǔn)備正常后，打開燃?xì)忾y門，接上啟動(dòng)電源，打開鑰匙，按下按鈕，-可啟動(dòng)機(jī)組。當(dāng)機(jī)組啟動(dòng)后，注意機(jī)油壓力表，有正常的機(jī)油壓力，萬萬不可粗心大意。啟動(dòng)后要怠速運(yùn)行一段時(shí)間，一是用以觀察各處、各部件的運(yùn)行情況是否異常，有無異常聲響，有問題處理、解決。怠速運(yùn)轉(zhuǎn)也是用來使機(jī)器升溫，冬季，這升溫很重要，將利于機(jī)器的使用。

2、 Idle running after starting: after preparing for normal operation, open the gas valve, connect the starting power supply, open the key, and press the button, - the unit can be started. When the unit starts, pay attention to the oil pressure gauge, there is normal oil pressure, never be careless. If there is abnormal operation of each part, observe whether there is abnormal operation for a period of time. Idle running is also used to make the machine warm up. In winter, this temperature rise is very important, which will be conducive to the use of the machine.

三、正常的負(fù)載輸出：當(dāng)經(jīng)怠速觀察，且機(jī)組已達(dá)到了溫度（觀察水溫表即可）就可以操縱電調(diào)“油門”將機(jī)組升速到標(biāo)定的工作轉(zhuǎn)速，調(diào)整機(jī)組的電壓和頻率都達(dá)到標(biāo)定值，則可向外界合閘，輸出負(fù)載。為了合閘時(shí)外界有負(fù)載使用，建議合閘前交將空車的轉(zhuǎn)速（頻率）稍稍偏高些。負(fù)載變化時(shí)，注意調(diào)速“油門”手柄，即電子調(diào)速器的電位器，適應(yīng)輸出，使得電壓和頻率的穩(wěn)定。

3、 Normal load output: when the idle speed is observed and the unit has reached the temperature (just observe the water temperature meter), the electric adjustment "throttle" can be operated to speed up the unit to the rated working speed, and the voltage and frequency of the unit are adjusted to reach the calibration value, then the machine can be switched on to the outside to output the load. In order to use the external load when closing, it is suggested that the speed (frequency) of the empty car be slightly higher before closing. When the load changes, pay attention to the speed control "throttle" handle, that is, the potentiometer of the electronic governor, to adapt to the output, so that the voltage and frequency are stable.
