4. Maintenance suggestions
4.1) Please keep the area around the handle clean and dry
4.2) When there is dust and dirt inside or outside the handle, please wipe it with a small amount of alcohol, but avoid a large amount of alcohol or moisture from penetrating into the bearing. The inside of the handle cannot be filled with oil (the bearings will become too hot to use), nor can it be filled with water (the bearings will rust and be damaged)
4.3) You can use an air gun for cleaning, but be aware that the gas emitted by the air gun may contain moisture. Be sure to avoid water vapor blowing into the bearing to prevent rust.
