Initial Inspection:
- Remove the pruner from its packaging.
- Check the blades for sharpness and ensure they open and close smoothly.

It is recommended to apply a light coat of oil to the blades and pivot point before the first use to ensure optimal performance and prevent rust.
3. Operating Instructions
The Corona BP 4250 Bypass Hand Pruner is designed for precise and clean cuts on live green wood and smaller dry branches. Follow these guidelines for effective and safe operation:
General Pruning Tips:
- Choose the Right Tool: Use bypass pruners for live wood to make clean cuts that heal quickly. For dead or woody material, consider anvil pruners or loppers for larger branches.
- Make Clean Cuts: Position the pruner with the cutting blade closest to the main stem or branch you are preserving. This ensures a clean cut that minimizes damage to the plant.
- Cut at an Angle: For optimal plant health, make cuts at a slight angle just above a bud or branch union.
- Avoid Over-cutting: Do not attempt to cut branches thicker than the pruner's 1-inch capacity. For larger branches, use loppers or a pruning saw to prevent damage to the tool and injury to yourself.
- Safety First: Always wear appropriate hand protection (gloves) when pruning. Keep fingers clear of the blades.

4. Maintenance
Regular maintenance will extend the life and performance of your Corona BP 4250 Bypass Hand Pruner. Proper care ensures the blades remain sharp and the tool operates smoothly.
Cleaning:
- After each use, clean sap and debris from the blades using a stiff brush and warm, soapy water.
- For stubborn sap, use a specialized sap remover or rubbing alcohol.
- Thoroughly dry the blades and all metal parts to prevent rust.
Sharpening:
- The MAXFORGED steel blades are resharpenable. Use a sharpening stone or diamond file designed for pruning tools.
- Follow the original bevel angle of the blade when sharpening. Sharpen only the cutting edge, not the flat side.
- Sharpen regularly to maintain optimal cutting performance.
Lubrication:
- Apply a few drops of light machine oil to the pivot point and spring mechanism after cleaning and drying.
- Open and close the pruner several times to distribute the oil.
Storage:
- Store the pruner in a dry place to prevent rust.
- Always engage the locking mechanism before storing to prevent accidental injury.
