4. Operating Instructions
Follow these steps for effective and safe operation of your Bahco PSL51 hedge shears:
- Prepare the Hedge: Remove any large branches or debris that might impede cutting with the shears.
- Positioning: Stand in a stable position, ensuring you have good balance. Avoid overstretching.
- Cutting Technique:
- Open the blades wide enough to encompass the material you wish to cut.
- Position the material as close to the pivot point of the blades as possible for maximum leverage.
- Apply steady, firm pressure to close the handles, making a clean cut.
- Avoid twisting the shears while cutting, as this can damage the blades or cause injury.
- Hedge Shaping: For a uniform hedge, work systematically, trimming small sections at a time. Step back periodically to assess your progress.
- Blade Cleaning During Use: If sap or debris builds up on the blades, clean them periodically with a damp cloth to maintain cutting efficiency.
5. Maintenance
Regular maintenance will extend the life of your Bahco PSL51 hedge shears and ensure optimal performance.
5.1 Cleaning
- After each use, clean the blades thoroughly to remove sap, dirt, and plant debris. Use a stiff brush and a damp cloth.
- For stubborn sap, use a specialized blade cleaner or a solution of warm soapy water. Dry the blades completely afterwards.
5.2 Lubrication
- Apply a few drops of light machine oil or specialized tool lubricant to the pivot point and along the cutting edges of the blades after cleaning and drying.
- Open and close the shears several times to distribute the lubricant evenly. This prevents rust and ensures smooth operation.
5.3 Sharpening
- Dull blades can tear plants and require more effort. Sharpen the blades regularly using a sharpening stone or file designed for garden tools.
- Maintain the original bevel angle of the blades. Sharpen only the cutting edge, not the flat side.
- If you are unsure about sharpening, consult a professional or refer to specific sharpening guides for bypass shears.
5.4 Storage
- Store the shears in a dry environment to prevent rust.
- Always close the blades and, if available, use a blade guard for safety during storage.
- Keep out of reach of children and unauthorized users.
6. Troubleshooting
Here are solutions to common issues you might encounter with your hedge shears:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blades feel stiff or hard to open/close. | Accumulated sap/debris, lack of lubrication, rust. | Clean blades thoroughly. Apply lubricant to the pivot point and blades. If rusty, clean with a wire brush and apply rust-inhibiting oil. |
| Blades are not cutting cleanly (tearing branches). | Dull blades, damaged blades. | Sharpen blades. Inspect for nicks or damage; if severely damaged, consider professional repair or replacement. |
| Handles feel loose. | Loose fasteners. | Check and tighten any visible screws or bolts on the handles. Do not overtighten. |
