| SN | SYMPTOMS | Probable Cause of Failure | Remedial Action |
| 01 | Low air pressure at outlet | 1. Low air pressure
2. incomplete opening of ball valve
3. Air leakages in the system
| 1. Ensure inlet air pressure at 5 Kg/cm2
2. Open the ball valve completely and replace if required
3. Arrest the air leakages in the system
|
| 02 | Unusual sound in the system | 1. Failure of bearings on the shaft
2. Improper alignment of coupling
3. Failure of bearings of the motor
4. Fasteners may got loosen
| 1. Lubricate the bearing and replace it
2. Align the coupling between motor and shaft properly
3. Replace the bearings of the motor
4. Tight the loosen fasteners
|
| 03 | cone assembly not rotating in rated speed | 1. Motor may not rotating in rated speed
2. Coupling alignment is not in proper way.
3. Belt tension may be reduced.
4. Key way of the coupling may be damaged
| 1. Check the rated speed of the Motor
2. Align the coupling between motor and shaft properly.
3. Adjust the Belt tension
4. Replace the Key way of the coupling
|
| 04 | cone assembly not cleaned completely | 1. Dry grease stick to cone assembly
2. Motor may Rotating at low speed (Low RPM)
3. Air pressure may be less
| 1. Clean the dry grease manually
2. Ensure the speed of the motor
3. Air pressure should be 5 kg/cm2
|
| 05 | Slipping of cone assembly from shaft | 1. Allen screw threads may be worn out
2. Internal threading of the shaft may be worn out
3. Improper locking of cone assembly
| 1. Replace the worn out screws
2. Provided new threading to the shaft
3. Lock the Cone assembly tightly
