Removing the Old String

When Removing the Old String from your tree pruner, it’s essential to follow these steps:

  • Locate the knot at the end of the pole that secures the old string.
  • Untie the knot carefully to release the tension on the string.
  • Slowly unwind the old string from the pruner head, ensuring it doesn’t get tangled.
  • Inspect the string for any damage or signs of wear that may require replacing it entirely.
  • Dispose of the old string properly to avoid any hazards in your workspace.

Stringing the Tree Pruner

To restring your tree pruner, follow these steps:

  • 1. Measure Replacement String:
  • Cut a piece of replacement string that matches the length of the old one.
  • 2. Thread the String:
  • Insert one end of the string through the hole in the pruner head.
  • 3. Knot the String:
  • Tie a secure knot at the end of the string to prevent it from slipping out.
  • 4. Wind the String:
  • Wind the string around the pruner head following any guides or grooves.
  • 5. Secure the String:
  • Ensure the string is tight and won’t unravel during use.

Testing and Adjusting

  • Test Cut: Try making a test cut on a small branch to check the string’s functionality. Ensure it cuts cleanly and without snagging.
  • Adjust Tension: If the cut isn’t smooth or if the string feels too loose or tight, adjust the tension accordingly.
  • Tighten or Loosen: Depending on your findings, you may need to tighten or loosen the string to achieve the desired result.
  • Fine-tuning: Make small adjustments until you find the right balance of tension for efficient cutting.
  • Regular Checks: Periodically inspect the string tension during use to prevent problems and maintain cutting performance.
