I was almost done sharpening my chain when I noticed a raker broken off. Should I keep that tooth sharp or dull it?
First, take this as a 'heads-up'/warning; clean and inspect the rest of the entire chain very thoroughly, especially in the damaged area; discard the whole chain if it is an 'off-brand' or any doubt - check the bar channel for any sign of a nick or deformation. Examine the exposed break surface. Try to find the cause.
If all good - One raker missing; sharpen as usual, you'll never know it in the log.
Always wear the proper protective equipment!!!!
