I. Install the Wind Deflector

II. Adjust the Drive Belt

III. Notes

1. Do not rotate the diesel generator by pulling or prying the fan during use, as this may cause serious personal injury or damage to the fan blades. The fan blades are rotating parts, and improper operation may lead to blade detachment or personal entanglement accidents.

2. Do not attempt to repair broken, bent blades or blades lacking balance weights, as this will damage the dynamic balance of the fan. Once the dynamic balance is destroyed, the fan will generate severe vibration during operation, which may affect the overall stability of the generator set and even cause damage to other components.

3. Do not try to increase the air supply capacity by bending the blades. Bending the blades will increase the stress on the blade material, leading to fatigue damage of the blades and even sudden breakage during operation, which poses a great safety hazard.

4. The fan of the Cummins diesel generator set adopts a double-layer supporting plate manufactured by stamping and riveting. During the operation of the diesel generator, the direction of the fan assembly should be predicted according to the principle that the concave arc surface of the fan blade is the wind-pressing surface, consistent with the rotation direction of the fan. Never install the fan in the wrong direction; otherwise, the non-wind-pressing surface of the fan blade will become the wind-pressing surface, which will significantly reduce the air volume of the fan and affect the heat dissipation effect of the radiator, further leading to overheating of the generator set.
