5. Operating Instructions

These side cutters are designed for precise removal of plastic parts from model kit sprues. Follow these steps for optimal results:

1. Identify the Part: Locate the plastic part you wish to remove from the sprue.
2. Position the Cutter: Place the sharp, pointed blades of the side cutter against the gate (the small connection point) that attaches the part to the sprue. Aim to cut slightly away from the part itself to avoid damaging the part.

3. Make the Cut: Gently squeeze the handles to make a clean cut. The spring mechanism will assist in opening the blades after the cut.

4. Second Cut (Optional): For a cleaner finish, you may make a second cut closer to the part's surface after the initial removal. This minimizes the remaining gate mark.
5. Finishing: Any remaining nubs can be carefully trimmed with a hobby knife or sanded smooth for a perfect finish.

6. Maintenance

Proper maintenance will extend the life and performance of your side cutters:

• Cleaning: After each use, wipe the blades clean with a soft, dry cloth to remove any plastic residue.
• Lubrication: Periodically apply a small drop of light machine oil to the pivot point and spring to ensure smooth operation.
• Storage: Store the side cutters in a dry place, preferably with a protective cap or in a tool case, to prevent damage to the blades and corrosion.
• Sharpening: The blades are factory-sharpened for optimal performance. Avoid attempting to sharpen them yourself, as this can alter the blade geometry and reduce effectiveness.

7. Troubleshooting

If you encounter issues with your side cutters, consider the following:

• Dull Cuts or Crushing:
  • Cause: Using the tool on materials other than plastic, or attempting to cut overly thick plastic gates.
  • Solution: Ensure you are only cutting appropriate plastic model parts. For very thick gates, consider making two cuts: an initial rough cut further from the part, followed by a final trim closer to the part.
• Stiff Action:
  • Cause: Accumulation of debris or lack of lubrication at the pivot.
  • Solution: Clean the pivot area and apply a small amount of light machine oil.
• Damaged Blades:
  • Cause: Accidental drops, improper use (e.g., cutting metal), or excessive force.
  • Solution: Damaged blades cannot be easily repaired. Replace the tool if blades are chipped or bent, as this affects cutting performance and safety.
