Operating Instructions
The Makita DUH523Z is designed for ease of use and efficient trimming.
- Starting the Trimmer: To start the trimmer, depress the safety lock-off button and then squeeze the trigger switch. The blades will begin to move.
- Trimming Technique:
- Hold the trimmer firmly with both hands.
- Maintain a stable stance.
- Move the trimmer smoothly along the hedge, allowing the blades to cut through the branches.
- For best results, use a sweeping motion, cutting small amounts at a time.
