Product Features
The SEYVUM Cordless Pole Hedge Trimmer is designed for efficient and convenient hedge trimming with several key features:
- Efficient Cutting Capability: Equipped with 20-inch hardened steel double-acting blades for smooth, precise cutting with minimal vibration. It can cut branches up to 5/8 inch thick.
- Telescopic Extension Pole: The pole extends from 7.5 feet to 9 feet, allowing for a total reach of up to 15 feet when combined with user height. This feature eliminates the need for a ladder for most high hedges. The pole is removable for compact storage.
- Adjustable Trimmer Head: The trimmer head can be adjusted from 0 to 135 degrees with 6 different positions, providing flexibility to trim hedges at various angles, including high branches, side branches, and low shrubs.
- Dual 2.0Ah Batteries: Includes two 2.0Ah lithium-ion batteries. Each battery provides up to 25 minutes of continuous use, allowing for extended work time by alternating batteries. The batteries feature overload, overheating, over-discharge, over-current, and over-voltage protection for enhanced durability and safety.
- Lightweight and Ergonomic Design: Weighing approximately 9.9 pounds, the trimmer is designed for ease of use. The ergonomic shoulder strap distributes weight, reducing strain on arms and shoulders. Non-slip rubber grips ensure comfortable and stable control.
- Powerful Motor: Operates at 1500 RPM for effective and quick trimming.

Setup
1. Assembly
- Connect Trimmer Head to Pole: Align the trimmer head with the extension pole. Push them together until they click securely into place. Ensure the connection is firm and there is no wobble.

2. Battery Charging and Installation
- Charge Batteries: Insert a 2.0Ah battery into the provided charger. Plug the charger into a standard electrical outlet. The indicator light on the charger will show the charging status. A full charge typically takes 2 hours.

Operating Instructions
1. Starting and Stopping the Trimmer
- To Start: Ensure the battery is installed. Press and hold the safety lock-off button, then squeeze the trigger switch.
- To Stop: Release the trigger switch. The blades will stop quickly.
2. Extending the Pole
- Loosen the locking collar on the extension pole.
- Extend the pole to the desired length (between 7.5 ft and 9 ft).
- Tighten the locking collar securely to prevent the pole from retracting during use.
3. Adjusting the Trimmer Head Angle
- With the trimmer off and the battery removed, locate the angle adjustment button/lever on the trimmer head.
- Press the button/lever and adjust the head to one of the 6 available positions (0-135 degrees).
- Release the button/lever and ensure the head locks firmly into the chosen position before use.
4. Trimming Techniques
- General Trimming: Use a sweeping motion, moving the trimmer blades along the hedge. Cut small amounts at a time.
- High Hedges: Use the extended pole and adjust the head angle to comfortably reach the top and sides. Work from top to bottom.
- Side Trimming: Hold the trimmer with the blades parallel to the hedge side. Move steadily along the length.
- Thick Branches: The trimmer can cut branches up to 5/8 inch. Do not force the blades through thicker material.
