1. Important Safety Instructions
Always read and understand this manual before operating the hedge trimmer. Failure to follow instructions can result in serious injury or property damage.
- Personal Protective Equipment (PPE): Always wear safety goggles, gloves, and appropriate clothing to protect against flying debris and sharp blades.
- Dual Safety Lock: The trimmer is equipped with a dual safety lock mechanism to prevent accidental activation. Both the safety buttons and the power switch must be engaged simultaneously to operate the tool.
- Blade Guard: Always use the blade guard when the trimmer is not in use or during transport.
- Clear Work Area: Ensure the work area is clear of bystanders, children, and pets.
- Inspect Before Use: Before each use, inspect the trimmer for any damage, loose parts, or dull blades. Do not operate a damaged tool.
- Branch Size: This hedge trimmer is designed for soft branches up to 1/2 inch diameter and can cut through branches up to 2/3 inches thick (blade gap). For thicker or hardwood branches, use specialized tools like pruning shears or a mini chainsaw to avoid damaging the trimmer's motor or blades.
- Avoid Forcing: Do not force the tool through thick branches. If a branch gets stuck, immediately disconnect the battery to prevent engine damage.
- Secure Grip: Maintain a firm, non-slip grip on both handles during operation.

4. Operating Instructions
The DocSmart 20'' Cordless Hedge Trimmer is designed for efficient and precise trimming of hedges and bushes.
- Powering On: To start the trimmer, simultaneously press the safety buttons on the handle and then squeeze the power switch. Release the safety buttons once the blades begin to move.
- 180° Rotatable Head: The trimmer features a 180° rotatable head for enhanced maneuverability and comfort. To adjust the head, press the rotation button (usually located near the main handle) and rotate the blade assembly to your desired angle (e.g., 90° left, horizontal, 90° right). Release the button to lock it in place. This feature is particularly useful for shaping hedges in tight areas or for vertical trimming.
- Trimming Technique: Hold the trimmer firmly with both hands. Use a sweeping motion to cut through branches. For best results, cut small amounts at a time. Avoid overreaching or cutting above shoulder height.
- Blade Performance: The 20.67-inch 65Mn steel blade operates at up to 3000 RPM, providing sharp, clean cuts. It is ideal for soft branches up to 1/2 inch in diameter.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your hedge trimmer.
- Blade Care: After each use, clean the blades of any sap, debris, or plant residue. Apply a thin layer of liquid oil to the blades to protect them from rust and reduce wear and tear.
- Battery Charging: The 2000mAh batteries provide approximately 120 minutes of working time on a full charge. Recharge batteries as needed. Store batteries in a cool, dry place away from direct sunlight.
- Storage: Always attach the blade guard before storing the hedge trimmer. Store the tool in a dry, secure location out of reach of children.
