Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your grooming kit.
- Before Cleaning: Always ensure the trimmer is turned off and unplugged from the power source.
- Cleaning Blades: Use the provided cleaning brush to remove hair clippings from the blades and comb attachments. For a more thorough clean, some heads may be rinsed under running water (check product specifications for water resistance). Ensure the heads are completely dry before reattaching or storing.
- Oiling Blades: After every few uses, or if the blades feel sluggish, apply a small drop of the lubricating oil (provided) to the blades. Turn on the trimmer for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and smooth operation.
- Cleaning the Main Unit: Wipe the main unit with a dry or slightly damp cloth. Do not submerge the main unit in water.
- Storage: Store the trimmer and its accessories in a dry place, away from direct sunlight and moisture. The charging base can be used for organized storage.
