1、检查机组表面是否清洁；其他运动部件的地脚螺母、飞轮螺钉和螺母是否松动，发现问题及时拧紧。

1. Check whether the unit surface is clean; Check whether the anchor nuts, flywheel screws and nuts of other moving parts are loose. If any problem is found, tighten them in time.

2、检查各部位间隙是否正确，特别要仔细检查各进排气门间隙和减压机构间隙是否合适。

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 the pressure reducing mechanism are appropriate.

3、将各气缸置于减压位置，转动曲轴，检查各气缸运转是否有异响，曲轴是否转动自如。同时将油泵入摩擦面，然后关闭减压机构，摇动曲轴。检查气缸是否漏气。如果摇动曲轴，很难感觉到感染，说明拧紧是正常的。

3. Place each cylinder in the pressure reducing position, rotate the crankshaft, and check whether there is abnormal sound during the operation of each cylinder and whether the crankshaft rotates freely. At the same time, put the oil pump into the friction surface, then close the pressure reducing mechanism and shake the crankshaft. Check the cylinder for air leakage. If you shake the crankshaft, it is difficult to feel the infection, indicating that tightening is normal.

4、检查供油系统状况：①检查油箱盖上的通风孔是否通畅。如果孔中有污垢，则应进行清洁。检查添加的气体是否符合要求的等级，油量是否充足，打开油路开关。②打开减压机构，摇动曲轴，各缸应有清脆的喷油声，说明喷油良好。喷油器和喷油泵的放气螺钉，用于排除油路中的空气。③检查油管及接头处是否有漏油现象，及时解决。

4. Check the condition of oil supply system: ① check whether the ventilation hole on the fuel tank cover is unobstructed. If there is dirt in the hole, clean it. Check whether the added gas meets the required grade and whether the oil quantity is sufficient, and turn on the oil circuit switch. ② Open the pressure reducing mechanism and shake the crankshaft. Each cylinder should have a clear oil injection sound, indicating that the oil injection is good. The bleed screw of the fuel injector and fuel injection pump is used to remove air from the oil circuit. ③ Check whether there is oil leakage at the oil pipe and joint, and solve it in time.

5、检查水冷系统状况：①检查水箱内的冷却水是否充足。如果水量不足，则加入足够的清洁软水。②检查接头水管是否有漏水现象，发现问题及时解决。③检查冷却水泵叶轮转动是否灵活，传动皮带是否张紧。检查传动带的松紧度，在转动的皮带中间用手推动，传动带应下压10~15mm。

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

6、检查润滑系统状况：①检查油管及管接头处是否有漏油现象，及时解决。②检查油底壳的油量，拉出曲轴箱旁的量油尺，检查油位高度是否符合端部要求，否则应加油。通常需要注意三个方面：加油的时候加太多气体泄漏到曲轴箱中，机油被稀释。C。冷却水泄漏到油中。③需要手动加油的油孔应注满油，并用油枪涂抹润滑脂。

6. Check the lubrication system: ① check whether there is oil leakage at the oil pipe and pipe joint, and solve it in time. ② Check the oil level of the oil pan, pull out the dipstick beside the crankcase, and check whether the oil level meets the end requirements, otherwise add oil. Three aspects should be paid attention to: too much gas is added to the crankcase during refueling, and the engine oil is diluted. C. Cooling water leaks into the oil. ③ The oil hole requiring manual oiling shall be filled with oil and greased with an oil gun.

7、检查启动系统状况：①用点启动瓦斯发电机组：a检查启动电池的比重是否在1.240~1.280范围内。如果比重小于1.180，则电池不足。湾。检查电源线是否正确。C。检查电池端子是否有污垢或氧化现象，应打磨清洁。d。检查起动电机与电磁保持机构的电气接触是否良好。

7. Check the starting system status: ① start the gas generator set at the point of use: a check whether the specific gravity of the starting battery is within the range of 1.240~1.280. If the specific gravity is less than 1.180, the battery is insufficient. Bay. Check whether the power cord is correct. C. Check the battery terminals for dirt or oxidation, and polish and clean them. D. Check whether the electrical contact between the starting motor and the electromagnetic holding mechanism is good.
