1. Check whether the surface of the unit is clean; check whether the nuts of foundation nuts, flywheel screws and other moving parts are loose; if any problem is found, fasten them in time.

2、檢查各部分間隙是否正確，特別應仔細檢查各進、排氣門的間隙幾減壓機構間隙是否合適要求。

2. Check whether the clearance of each part is correct, especially carefully check whether the clearance of each inlet and exhaust valve and the clearance of pressure reducing mechanism meet the requirements.

3、將各氣缸置于減壓位置，轉動曲軸檢聽各缸機件運轉聲音有沒有異常聲響，曲軸轉動是否自如，同時將機油泵進個摩擦面，然后，關上減壓機構，搖動曲軸。

3. Put each cylinder in the pressure reducing position, rotate the crankshaft, check whether there is abnormal sound in the operation of each cylinder and whether the crankshaft can rotate freely. At the same time, put the oil pump into a friction surface, then close the pressure reducing mechanism and shake the crankshaft.

檢查氣缸是否漏氣，如果搖動曲軸時，感觸感染很吃力，表示緊縮正常。

Check whether there is air leakage in the cylinder. If the crankshaft is shaken, it feels that the infection is very hard, indicating that the tightening is normal.

4、檢查燃油供給系統的情況：①檢查燃油箱蓋上的通氣孔是否順暢，若孔中有污物應清除清潔。加進的燃氣是否合適要求的牌號，油量是否充沛，并打開油路開關。②打開減壓機構搖轉曲軸，每個氣缸應有清脆的噴油聲音，表示噴油良好，若聽到噴油聲不來油，可能油路中有空氣，此時可旋松燃氣濾清器和噴油泵的放氣螺釘，以排除油路中的空氣。③檢查油管及接頭處有沒有漏油現象，發現題目及時措置解決。

4. Check the condition of the fuel supply system: ① check whether the air vent on the fuel tank cover is smooth. If there is any dirt in the air vent, clean it. Whether the added gas is suitable for the required brand, whether the oil quantity is sufficient, and turn on the oil circuit switch. ② Open the pressure reducing mechanism and rotate the crankshaft. Each cylinder should have a clear sound of fuel injection, indicating that the fuel injection is good. If the sound of fuel injection does not come, there may be air in the oil circuit. At this time, loosen the vent screw of gas filter and fuel injection pump to remove the air in the oil circuit. ③ Check whether there is oil leakage at the oil pipe and joint, and deal with the problem in time.

5、檢查水冷卻系統的情況：①檢查水箱內的冷卻水量是否充沛，若水量不足，應加足清潔的軟水。②檢查接頭水管有沒有漏水現象，發現題目及時措置解決。③檢查冷卻水泵的葉輪轉動是否靈活，傳動帶松緊是否適當。檢查傳動帶松緊，在轉動帶中部用手推壓，傳動帶被壓下10~15mm為好。

5. Check the condition of the water cooling system: ① check whether the cooling water in the water tank is sufficient. If the water is insufficient, add enough clean soft water. ② Check whether there is water leakage in the joint pipe, and deal with the problem in time. ③ Check whether the impeller of the cooling water pump rotates flexibly and whether the tightness of the drive belt is appropriate. Check the tightness of the drive belt, push it by hand in the middle of the rotating belt, and the drive belt is pressed down by 10 ~ 15mm.

6、檢查潤滑系統的情況：①檢查機油管及管接頭處有沒有漏油現象，發現題目及時措置解決。②檢查油底殼的機油量，將曲軸箱旁的量油尺抽出，不雅察機油面的高度是否合適端方的要求，不然應添加機油，對燃氣機，冬季加8號或11號燃氣機機油，夏季加14號機油。如發現油面高度在端方高度以上時，應認真闡發機油增多的啟事，通常有三個方面的事項需要注意：a.加機油時，加的過量。b.燃氣漏進曲軸箱，將機油沖稀。c.冷卻水漏進機油中。③需要人工加油的油孔，均應加注機油做用油槍加注潤滑脂。

6. Check the lubrication system: ① check whether there is oil leakage at the oil pipe and pipe joint, and deal with the problem in time. ② Check the amount of oil in the oil pan, pull out the dipstick beside the crankcase, and check whether the height of the oil surface is suitable for the requirements of the end, otherwise, add oil. For gas engine, add No. 8 or No. 11 gas engine oil in winter and No. 14 gas engine oil in summer. If it is found that the oil level is higher than the end height, the notice of oil increase should be carefully explained. There are usually three matters to be noted: A. when adding oil, add too much oil. b. The gas leaks into the crankcase and dilutes the oil. c. Cooling water leaks into the oil. ③ The oil holes that need to be filled manually should be filled with engine oil, and the grease should be filled with oil gun.

7、檢查起動系統情況：①用點起動燃氣機組：a.先查起動蓄電池電液比重是否在1.240~1.280范圍內，若比重小于1.180表明蓄電池電量不足。b.檢查電源電線是否正確。c.檢查蓄電池接線柱上有沒有積污或氧化現象，應將其打磨清潔。d.檢查起動電動機及電磁把持機構等電氣觸電接觸是否良好。

7. Check the starting system: 1. Start the gas turbine at a certain point: A. check whether the specific gravity of the starting battery is in the range of 1.240 ~ 1.280. If the specific gravity is less than 1.180, it indicates that the battery is insufficient. b. Check that the power cord is correct. c. Check whether there is dirt or oxidation on the battery terminals, and polish them clean. d. Check whether the electric contact of starting motor and electromagnetic holding mechanism is good.
