How to Sharpen a Chainsaw with the Granberg G1012XT

Sharpening a chainsaw using the Granberg G1012XT involves a combination of a 12-volt high-speed grinder and precision file adjustment. This method merges the speed of a grinder with the accuracy of manual filing. Here’s a step-by-step guide to effectively use the G1012XT for sharpening your chainsaw:

1. Understand the Setup

The G1012XT is equipped with various adjustment features:

  • Tooth Length Adjustment: Located near the grinding stone, this adjusts the cutting length of each tooth.
  • Grinding Stone Height Adjustment: This screw adjusts the height of the stone. Each number on its circumference represents ten thousandths of an inch.
  • Top Plate Angle Adjustment: Adjusted using the top plate and a wingnut underneath, it sets the angle of sharpening.

2. Choosing the Right Grinding Stone

  • Select a stone that matches your chain type. For example, a 7/32 inch (5.5 mm) stone is ideal for 3/8 and 404 ripping chains.
  • Ensure the stone aligns correctly with the tooth. It should barely touch the tooth and fit within the arc of the sharpened portion.

3. Positioning the Stone

  • Bring the stone in close to the chain. It should just miss the inside of the tooth’s arc, only making contact for sharpening.
  • Adjust the height to ensure the stone is sharpening across the top edge and into the gullet of the tooth. You might need to lower the stone slightly for proper contact.

4. Sharpening Process

  • Begin sharpening by lightly touching the stone to the chain, focusing on not over-sharpening.
  • Move to the next tooth of the same angle, ensuring consistent removal across all teeth.
  • A well-maintained chain usually needs just a few strokes to return to its original sharpness.

5. Ensuring Consistent Tooth Length

  • Consistency in tooth length is crucial for preventing the chain from cutting in a curve.
  • Use a simple screw and nut device or a vernier caliper to measure and compare the length of the teeth.
  • Adjust the tooth length accordingly to ensure uniformity across the chain.

Tips for Using the Granberg G1012XT

  • Always wear protective gear while sharpening.
  • Regularly check the condition of the grinding stone.
  • After sharpening, test the chain for even cutting performance.
  • Maintain a steady hand and avoid applying excessive pressure.

By following these steps and tips, you can efficiently sharpen your chainsaw using the Granberg G1012XT, ensuring precise and consistent results every time.
