1. Open the back cover of the motor, first use a cloth to wipe off the dust, and then pour a dozen drops of sewing machine oil into the oiling hole to moisturise and maintain the bearing.
2. Keep all switch buttons in the off position to prevent the internal spring from failing due to elastic fatigue.
3. The electroplating grille can be coated with some light wax to keep it clean. Any oil that falls on the plastic fan blades and net cover must be wiped off to avoid damage caused by chemical reaction for a long time.
4. The grille and fan blades of the electric fan should be removed. First, use a soft and clean cloth with soapy water to clean the dirt on it, then rinse off the soapy liquid with clean water, and finally wipe it with a dry cloth and let it dry.
5. The action should be light and do not collide with the fan blade. If it is a plastic fan blade, it cannot be scrubbed with hot water to maintain the original angle of the fan blade, otherwise, it will affect the use. Do not use gasoline, alcohol and other liquids to scrub the parts, otherwise the paint will age, fade or even fall off and rust.
