- Squeeze the trigger on the rear handle to start the blades. The blades will stop quickly when the trigger is released.
Trimming Techniques
For best results and safety, follow these trimming guidelines:
- Hold the trimmer at a slight angle to the hedge, moving it in a sweeping motion.
- Cut through branches up to 1/2-inch thick. Avoid forcing the blades through thicker material.
- For vertical cuts, begin at the bottom and sweep upwards.
- For horizontal cuts, hold the blade flat and sweep across the top of the hedge.
- Maintain a firm grip with both hands to ensure control and reduce fatigue.
