First loosen the generator fixing screw and the belt tightness adjustment screw, push the generator against the engine to minimize the distance between the pulleys,
then put the belt, straighten it and adjust the belt To the appropriate tightness, tighten the motor mounting screws and the adjustment screws.
Preparation before starting the unit:
1. Check the lubricating oil level, coolant level and fuel quantity;
2. whether there are oil or water leaks in various pipelines and joints of oil, lubrication, cooling and other systems;
3. Check the electrical circuits for leakage hazards such as broken skin, loose ground wires and electrical circuits, and whether the unit and foundation are solid;
4. If the ambient temperature is below zero, a certain proportion of antifreeze must be added to the radiator;
p>
5. The diesel generator set is started for the first time or when restarting after a long shutdown, you must first use a hand pump to drain the air in the fuel system.

Operating procedures
1. Before you start, check whether there is enough oil in the fuel tank, each oil pipe. and seals There is no oil leak; the water in the cooling system is sufficient, clean and leak-free, and the fan belt is tight and tight.
Check that the transmission parts of the internal combustion engine and generator should be reliably connected, the output line wires should be well insulated, and all instruments should be complete and efficient .
2. After starting, it should run at low speed for 3-5 minutes. The operation can only be started oncee oil temperature and pressure are normal.
The generator should not make any abnormal noise when increasing the speed, the slip ring and commutator brushes should be in good contact, and there should be no jumps or sparks. After the operation is stable and the frequency and voltage reach the rated values, power can be supplied externally.
3. When abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting.
4. The generator power factor should not exceed 0.95 in late phase (lag). The variation range of the frequency value should not exceed 0.5 Hz.
5. Before shutdown, you must first turn off the main switches of each power branch, reduce progressicharge, then turn off the main power switch to the generator.
5. p>Return the excitation rheostat to the maximum resistance position, reduce the voltage to the minimum value, then turn off the excitation switch and the neutral point grounding switch, and finally stop the operation of the internal combustion engine.
