Removing the Old String

When it comes to restringing a tree pruner, the first step is to remove the old string. Here’s how you can do it effectively:

  • Locate the Pulley System: Find the pulley system on the tree pruner. This is where the string wraps around to extend and retract the cutting blade.
  • Cut the Old String: Use scissors or a knife to carefully cut the old string. Make sure to remove any knots and untangle the string from the pulley system.
  • Detach the Old String from the Blade: Unhook the old string from the blade, ensuring it’s completely free from any attachments.
  • Inspect for Any Remaining String: Double-check the entire pruner to ensure no remnants of the old string are left behind. Clean out any debris that may have accumulated.
  • Dispose of the Old String: Properly dispose of the old string to keep your working area tidy and organized.

By following these steps, you’ll successfully complete the crucial task of removing the old string from your tree pruner, setting the stage for a smooth restringing process.

Stringing the Tree Pruner

To start stringing your tree pruner, you’ll first need to cut a new piece of rope that is slightly longer than the original one you removed. Keep in mind that having extra length will give you room for adjustments later on.

Here’s a simple guide to help you string your tree pruner effectively:

  • Feed one end of the new rope through the hole in the blade where the old string was attached. Ensure it is securely knotted to prevent it from slipping out.
  • Guide the rope up towards the pulley system, making sure it follows the correct path as shown by the previous string’s markings.
  • Loop the rope over the pulley wheel and then bring it back down towards the blade. This step ensures that proper tension is maintained when cutting branches.
  • Attach the other end of the rope to the locking mechanism, making sure it is securely fastened.
  • Test the functionality of your newly strung tree pruner by engaging the rope and observing how it operates. Make any necessary adjustments to the tension for optimal performance.
