6. Operating Instructions
6.1. Turning On/Off
Press the On/Off switch located on the front of the clipper to turn it on. Press it again to turn it off.
6.2. Adjusting Blade Length
The blade lever on the side of the clipper allows for fine adjustment of the cutting length without a guide comb. Move the lever up or down to select your desired blade length for tapering and blending.
6.3. Selecting Speed
The clipper features two speeds: Normal and Turbo. The LCD display will indicate when Turbo mode is active. Consult the product's specific controls for switching between these modes, typically a dedicated button or a double-press of the power button.
6.4. Hair Cutting Techniques
For best results, ensure hair is clean and dry. Use the appropriate guide comb for the desired length. Start with a longer comb if unsure. Move the clipper against the direction of hair growth for an even cut. For detailed styling, refer to professional hair cutting guides.

7. Maintenance
Regular cleaning and maintenance will prolong the life of your clipper and ensure optimal performance.
7.1. Cleaning the Blades
- Turn off the clipper and remove any attached guide comb.

- Do not rinse the clipper under water unless explicitly stated as waterproof. The KM-1990 is not washable.
7.2. Lubrication (Oiling)
After each use, or at least once a month, apply a few drops of clipper oil (not included, but commonly available) to the blades. This helps maintain cutting efficiency and prevents rust.

- Turn the clipper on for a few seconds to distribute the oil.
- Wipe off any excess oil with a soft cloth.
