Q. Do these wheels require any preparation to use?
A. Yes. The edges of these wheels are square and must be rounded before use. Rounding is done using a Dressing Stick, and is checked using the Grinding Wheel Radius Check Tool.
Q. How do determine what pitch my chain is?
A. To determine the pitch of a chain, measure the distance between the centers of any three consecutive rivets and divide by 2. A result of .375" means 3/8 pitch. Or, make it simple and use our Pitch-N-Gauge Saw Chain Check Tool.
