5. Operating Instructions
Operating your hedge trimmer is straightforward. Follow these steps for effective trimming:
- Grip: Hold the trimmer firmly with both hands, one on the front handle (which includes the front switch lever) and the other on the rear handle, ensuring your fingers are on the trigger switch.
- Start: To activate the trimmer, simultaneously press the front switch lever (all around the front handle) and the trigger switch. The dual-switch design ensures safety.
- Trimming: Guide the 22-inch dual-action blade along the hedges or shrubs. The trimmer operates at up to 2800 SPM (Strokes Per Minute) and can cut branches up to 3/4 inch thick.
- Movement: Use a smooth, sweeping motion for even cuts. The lightweight design (5.25 lbs) and ergonomic handle allow for precise control and reduced fatigue during extended use.
- Stop: Release either the front switch lever or the trigger switch to stop the trimmer.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your hedge trimmer:
- Blade Cleaning: After each use, clean the blades of any sap, leaves, or debris. Use a stiff brush and a mild cleaning solution if necessary.
- Blade Lubrication: Apply a light coat of machine oil or blade lubricant to the blades to prevent rust and ensure smooth operation. The blades have undergone anti-rust treatment for extended life.
- Blade Sheath: Always re-attach the blade sheath when the trimmer is not in use or during storage to protect the blades and prevent accidental injury.
- Battery Care: Store batteries in a cool, dry place. Avoid extreme temperatures. Do not store fully discharged batteries for extended periods.
- General Cleaning: Wipe down the body of the trimmer with a damp cloth to remove dirt and dust.
