4. Operating Instructions
Follow these instructions for safe and effective operation of your BLACK+DECKER PH5551-QS pole hedge trimmer.
4.1 Adjusting the Telescopic Handle
The fiberglass telescopic handle allows you to extend the reach of the trimmer for high hedges. To adjust:
- Loosen the locking collar on the telescopic pole.
- Extend or retract the pole to the desired length. The maximum reach is approximately 4 meters.
- Tighten the locking collar securely to prevent the pole from slipping during use.
4.2 Adjusting the Pivoting Head
The pivoting head can be adjusted to 6 different positions to achieve various cutting angles. To adjust:
- Ensure the trimmer is disconnected from the power supply.
- Locate the head adjustment button or lever.
- Press the button/lever and rotate the head to the desired angle (-60° to +90°).
- Release the button/lever and ensure the head locks firmly into place before use.
4.3 Starting and Stopping
The trimmer features a double switch for enhanced safety:

4.4 Cutting Techniques
For best results and safety, follow these cutting techniques:
- Maintain Balance: Always maintain a firm grip with both hands and ensure stable footing.
- Sweep Motion: Use a wide, sweeping motion to cut hedges. For vertical surfaces, cut from bottom to top.
- Avoid Overloading: Do not force the trimmer through thick branches. The 22mm blade spacing is for maximum capacity; cut smaller sections if resistance is met.
- High Hedges: Utilize the telescopic handle and pivoting head to reach the top and sides of tall hedges without using a ladder. Work from a safe distance.
