Assessing the Problem

To successfully fix your tree pruner, you need to first identify the issue at hand. Here’s how to assess the problem effectively:

  • Inspect the Blades: Check if the blades are dull, damaged, or misaligned. This can affect the pruner’s performance.
  • Look for Rust: Rust can hinder the cutting ability of the pruner. Make sure to examine the blades and joints for any signs of corrosion.
  • Check the Handles: Ensure that the handles are not loose or damaged. The handles play a crucial role in the overall functionality of the pruner.
