PRECISION DETAIL TRIMMER: Create clean lines with surgical steel blades and 5-length comb (1–5mm). For best results, trim dry hair, start on longest setting, and comb hairs outward. Ensure the comb is locked into place to prevent shifting or uneven trims. DUAL-SIDED TRIMMER: B-directional trimmer attachment removes hair fast in sensitive areas. Use the included eyebrow comb for a clean, controlled look. Make sure attachments click securely into place before use to avoid shifting or breakage. NOSE & EAR TRIMMER: Narrow blade and extended neck make it easy to trim hard-to-reach areas. Clean blades regularly to maintain performance. If trimming feels weak, check for hair buildup or replace the battery to ensure full power. 9 LENGTH & STYLE SETTINGS: Trim from skin-close to 6mm with 3 heads, an eyebrow comb, and a 5-length adjustable comb. Attach combs firmly and begin on a higher length to avoid trimming too short. Comb hair in the same direction for even results. BATTERY & CLEANING TIPS: Use 1 AA alkaline battery only—rechargeables reduce performance. If the unit won't turn on, check that the battery is inserted correctly. Clean and oil blades often; clogged or dry cutters can impair trimming or cause it to stop.
