Before first use, fully charge the main clipper by plugging it into a power outlet; the charge light will indicate its status. Install the required batteries into the mini trimmer and nose trimmer (Info needed: specific battery type). To begin clipping, select the appropriate colour-coded guide comb and securely snap it onto the clipper blade. Ensure the blades are clean and lightly oiled before each use for optimal performance. After each use, turn off the device and carefully remove the guide comb. The clipper blade can be easily snapped off for thorough cleaning. Rinse the detached blade under running water to remove hair clippings, then allow it to air dry completely before reattaching. For the mini trimmer and nose trimmer, gently brush away hairs after use. Store all components in a dry, safe place away from direct sunlight. This kit is generally compatible with standard household power outlets for charging and is designed for personal grooming use.
