operation
After diesel generator installed, you can put into power, before each start, at least the following items should be checked
1.whether unit surface and around has debris
2.keep the into and exhaust channel of the engine room is smooth
3.the cooling liquid tank is normal
4.the air filter indicator directs normal
5.lubricating oil level is within normal range
6.the fuel valve is open, the supply of fuel to engine is normal
7.battery cables are connected correctly
8.power load device is ready,when the generator directly with the load, breaking the air switch before start.
