Determine the Correct String Length

To determine the correct string length for your Corona tree pruner, measure the length of the old string you removed.

  • Measure from the tip of the blade to the base of the handle.
  • Add a few extra inches for knotting.
  • Cut the new string to this calculated length.

Remember, having the right string length ensures smooth operation and avoids tangles.

Stringing the Tree Pruner

When stringing your tree pruner, here’s what you need to do:

  • Thread: Pass the new string through the hole adjacent to the blade.
  • Knot: Secure the string by tying a tight and secure knot at the end.
  • Tension: Ensure the string is taut but not overly tight to allow movement.

Avoid knots or tangles by following these simple steps:

  1. Pass Through: Thread the string through the designated path smoothly.
  2. Knot Securely: Tie a strong knot, ensuring it won’t unravel during use.
  3. Check Tension: Adjust the string tension for optimal cutting performance.

Remember, a properly strung tree pruner ensures smooth and efficient operation.
