5. Operating Instructions
5.1 Powering On/Off
Press the power button located on the front of the trimmer to turn it on or off.
5.2 Adjusting the Blade Lever
The trimmer features an adjustable blade lever for fine-tuning cutting lengths without a comb. Move the lever up for a shorter cut and down for a longer cut. This allows for precise blending and fading.
5.3 Trimming Techniques
- For general trimming: Attach the desired guide comb. Hold the trimmer with the blade flat against the hair and move it against the direction of hair growth.
- For outlining and detailing: Remove the guide comb. Use the edge of the T-blade to create sharp lines around the neckline, sideburns, and beard.
- For zero-gap cutting: The T-blade can be adjusted for an ultra-close cut. Exercise caution when performing zero-gap cuts to avoid skin irritation.
