  4. Sikker Clamps: Spænd boltene på clamping brackets to firmly secure the mill to the chainsaw bar. Use a small ratcheting torque wrench to ensure proper torque settings (10-12 lbs max) to avoid bending the saw bar. Ensure the chain is free to move and not touching any part of the mill.
  5. Juster dybde: Use the marked inches and millimeters on the uprights to set your desired cutting thickness.
  6. Installer sikkerhedsafskærmning: Attach the polycarbonate safety guard to the mill.

5. Betjeningsvejledning

Milling lumber requires careful technique to achieve straight and even cuts. The Granberg G777 is designed for ease of use, but practice is recommended.

5.1 First Cut Setup

For the first cut, a guide rail system is essential to ensure a straight initial surface. This can be a dedicated rail system (e.g., Granberg Easy-Rails), an aluminum ladder, or a straight 2x8 board securely attached to the log.

5.2 Milling Technique

  • Start the Chainsaw: Ensure the chainsaw is running at full RPM before engaging the chain with the wood.
  • Oprethold et jævnt tryk: Apply steady, even forward pressure on the mill. Avoid forcing the saw, as this can lead to stalling, poor cut quality, and damage to the chainsaw clutch. The saw should pull itself into the log.
  • Support the Powerhead: When exiting a cut, especially at the end of the log, apply slight upward pressure on the upright handle to prevent the mill from dipping and creating an uneven finish.
  • Use Wedges: As you progress through the cut, insert wooden or plastic wedges into the kerf (the cut opening) behind the chainsaw bar. This prevents the log from closing in and pinching the bar, which can cause kickback or chain damage.
  • Monitor Sawdust: Observe the sawdust being produced. Consistent, fine sawdust indicates a good cut. Large chips or excessive dust may indicate an issue with the chain or technique.

6. Vedligeholdelse

Regular maintenance ensures the longevity and optimal performance of your Granberg G777 mill and chainsaw.

  • Rengør efter hver brug: Remove all sawdust and debris from the mill frame, clamps, and chainsaw.
  • Inspicer fastgørelseselementer: Periodically check all nuts and bolts for tightness. Re-tighten as necessary to prevent vibration and ensure structural integrity.
  • Chainsaw Maintenance: Follow your chainsaw manufacturer's guidelines for chain sharpening, bar maintenance, and engine servicing. A sharp chain is crucial for efficient and safe milling.
  • Smøring: Ensure your chainsaw's bar and chain oil reservoir is full before each use.

7. Fejlfinding

If you encounter issues during milling, consider the following common problems and solutions:

ProblemMulig årsagLøsning
Ujævne snitLoose mill fasteners, dull chain, inconsistent feed rate, improper first cut guide.Tighten all fasteners, sharpen chain, maintain steady feed, ensure first cut guide is straight and secure.
Chainsaw stalls frequentlyDull chain, forcing the saw, log pinching the bar, insufficient chainsaw power.Sharpen chain, reduce feed pressure, use wedges, ensure chainsaw meets 50cc minimum requirement.
