Daily Cleaning

• After cutting off the power supply, remove the fan blades and filter screen. Wipe off dust with a soft cloth; for oil stains, clean with a neutral detergent and air-dry thoroughly.
• Clean dust on the motor housing and air vents to avoid accumulation affecting heat dissipation.

Lubrication Maintenance

• Inspect the motor bearings every 6-12 months and add special lubricating oil (such as sewing machine oil or motor-specific oil).
• Avoid using thick greases like butter, as they may cause adhesion and hinder rotation.

Regular Inspection

• Check for damage to the power cord and plug, and ensure terminal connections are tight. Replace or fasten immediately if any issues are found.
• Observe the motor’s operation after startup. If there is abnormal noise, excessive vibration, or irregular speed, cut off the power and inspect promptly.
• For long-term non-use, clean and store in a dry place to prevent coil moisture damage from humid environments.
