Setup and Installation
Proper installation of the replacement spring is crucial for the functionality of your pruning tool.
Required Tools:
- Small flathead screwdriver or pliers (for removing old spring)
- Safety glasses
- Clean cloth
Installation Steps:
- Safety First: Ensure the pruning tool is clean and free of debris. Wear safety glasses to protect your eyes.
- Remove Old Spring: If an old spring is present, carefully locate its attachment points. Use a small flathead screwdriver or pliers to gently disengage and remove the worn or broken spring. Note its orientation for correct replacement.
- Clean Area: Clean the area where the spring sits to remove any dirt or rust that could impede the new spring's function.
- Position New Spring: Take the Corona 6880-5 replacement spring. Identify the correct orientation. Typically, one end of the spring hooks into a designated hole or notch on one handle, and the other end hooks into a corresponding point on the other handle or blade mechanism.
- Attach Spring: Carefully attach one end of the spring first. Then, using gentle pressure, stretch the spring slightly to attach the other end to its designated point. Ensure the spring is securely seated and not under excessive tension that could cause it to dislodge.
- Test Functionality: Once installed, slowly open and close the pruning tool several times to ensure the spring operates smoothly and the blades return to the open position automatically. Check for any binding or unusual resistance.
- Final Check: Confirm all parts are secure and the tool functions correctly before use.
Operating Instructions
The 6880-5 spring works automatically within your TP 6881 pruning tool. After each cutting action, the spring will expand, pushing the handles apart and returning the blades to an open position, ready for the next cut. This mechanism reduces manual effort and speeds up repetitive pruning tasks.
Proper Usage:
- Always use the pruning tool for its intended purpose (cutting branches within its capacity).
- Avoid forcing the tool through overly thick or hard material, as this can damage the spring or other components.
- Keep fingers clear of the blades during operation.
Maintenance
Regular maintenance will prolong the life of your replacement spring and pruning tool.
- Cleaning: After each use, clean the spring and surrounding areas of the tool to remove sap, dirt, and debris. A damp cloth is usually sufficient. For stubborn residue, use a mild solvent.
- Lubrication: Periodically apply a light coat of rust-inhibiting oil to the spring and pivot points of the tool to ensure smooth operation and prevent corrosion.
- Inspection: Regularly inspect the spring for signs of wear, deformation, or rust. Replace the spring if it appears damaged or if the tool's automatic opening function becomes sluggish or fails.
- Storage: Store the pruning tool in a dry place to prevent rust and corrosion.
