The housing protects the internal components of the reducer, while the output flange and shaft provide the output connection. The worm gear and shaft work together to provide the reduction in speed and torque.

The performance of the reducer depends on correct installation, lubrication, and maintenance. For Shaft Mounting, it is important to ensure that the shaft and the gear unit hole are clean and free of burrs. Apply a suitable amount of lubricating oil to the shaft and hole to help with assembly and prevent friction corrosion. Slide the device onto the drive shaft, and install the key on the shaft. For Foot Mounting, install the equipment securely on a sturdy structure. Install the output extension shaft as required. The connection between the shafts should use an elastic coupling, and the deviation of the shafts should be within the range of the coupling. When installing belt pulleys or sprockets on two shafts, install them as close to the gearbox as possible. Do not hit the shaft when installing or removing transmission components, as this will damage the bearing.

For oil change, gearboxes with sizes 870 and 871 are lifetime lubricated but require oil changes in explosive environments. Gearboxes of all other sizes require oil changes according to the equipment's operating temperature. New gearboxes should have half of the oil changed after 1000 hours of operation, one year, or at the end of their designated service life. Maintenance should be performed in accordance with the manufacturer's recommendations.

| Problem | Cause | Solution |
|---|---|---|
| Oil Leakage | Worn-out seals or overfilling of lubricant | Replace the seals or reduce the amount of lubricant |
| Overheating | Excessive loading or inadequate lubrication | Reduce the loading or increase lubrication |
| Abnormal Noise | Worn-out or damaged gears or bearings | Replace the gears or bearings |
| Severe Vibration | Misalignment or unbalanced loading | Correct the alignment or balance the loading |
| Decrease in Output Torque | Worn-out or damaged gears or bearings | Replace the gears or bearings |
| Difficulty in Shifting Gears | Improper lubrication or damage to the shift fork or gear | Change the lubricant or replace the shift fork or gear |
| Sudden Stop in Operation | Damage to the output shaft or gear | Replace the output shaft or gear |
| Excessive Noise in Operation | Worn-out or damaged bearings or gears | Replace the bearings or gears |
