Usage:
- Caution: Do not apply excessive pressure when sharpening. Excessive downward force can cause premature stone failure. Use a back-and-forth sliding motion similar to using a round chainsaw file.
- We recommend using KOOL-GRIND lubricant to help prevent stone clogging and glazing. It also reduces heat and friction for a cooler, slower grind, helping minimize the risk of burning the chain and extending stone life.
