Safety Instructions

To reduce the risk of electric shock, injury, or fire, always follow these basic safety precautions:

  • Keep the appliance dry. Do not use it near water or while bathing/showering.
  • Do not immerse the trimmer in water. The blades are water-resistant for rinsing, but the main body is not fully waterproof.
  • Keep out of reach of children.
  • Always inspect the trimmer and attachments for damage before use. Do not use if damaged.
  • Use only the provided USB charging cable.
  • Unplug the trimmer before cleaning.
  • Do not operate if the trimmer is not working properly, has been dropped, or damaged.

Setup

Charging the Trimmer

  1. Connect the USB charging cable to the trimmer's charging port.
  2. Plug the other end of the USB cable into a compatible power source (e.g., car charger, laptop, power bank, or 5V wall adapter).
  3. Allow approximately 3 hours for a full charge. A full charge provides up to 180 minutes of continuous use.

Operating Instructions

General Trimming

  1. Ensure the trimmer is fully charged.
  2. Press the power button to turn on the trimmer.
  3. For longer lengths, attach a guide comb. For a close trim (0.1mm), use without a comb.
  4. Hold the trimmer with the blade flat against the skin or at a slight angle, moving against the direction of hair growth.
  5. Use smooth, even strokes.
  6. Turn off the trimmer after use by pressing the power button.

Detailing and Edging

The precision T-blade is ideal for defining hairlines, shaping beards, and trimming sideburns. Use the trimmer without a guide comb for the sharpest lines and closest cuts.

Maintenance

Cleaning the Blades

  2. Remove any attached guide comb.
  3. Use the included cleaning brush to remove loose hairs from the blade area.
  4. The blades are water-resistant and can be rinsed quickly under running water. Do not submerge the entire trimmer.
  5. Allow the blades to air dry completely before reattaching any combs or storing.

Cleaning the Trimmer Body

Wipe the aluminum body of the trimmer with a dry cloth. Do not use abrasive cleaners or immerse the body in water.
