• Verify all connections before trial run.

4. Operation

4.1 Commissioning

• Run no-load for 5–10 minutes; check for abnormal noise, vibration, or leaks.

• Gradually apply load only after stable no-load operation.

4.2 Operating Rules

• Operate strictly within rated parameters.

• Avoid frequent start-stop under full load.

• Stop immediately if overheating, noise, or leakage occurs.

5. Maintenance

• Lifetime lubrication: No oil changes required.

• Every 6 months: Check bolt tightness and housing for leaks; clean surface dust with a dry cloth.

• Do not use high-pressure water for cleaning.

• For internal faults, contact the manufacturer’s service team.

6. Troubleshooting

• Abnormal noise: Loose mounting, misalignment, or overload.

• Oil leakage: Damaged seals; replace seals professionally.

• Excessive vibration: Loose fasteners or unbalanced load.

• Overheating: Overload or insufficient cooling; reduce load and check ventilation.
