Final answer:
When ordering a replacement saw chain, you need to know the pitch, gauge, and number of drive links, to ensure compatibility and performance with your saw.
Step-by-step explanation:
When ordering replacement saw chain, it is important to know three key specifications to ensure that you get a compatible and efficient chain for your saw. These specifications are:
- The pitch of the chain, which is the distance between any three consecutive rivets divided by two. This measurement determines how well the chain fits on the saw's guide bar.
- The gauge of the chain, which is the thickness of the drive links that fit into the guide bar. The gauge must match the guide bar slot size to ensure proper operation.
- The number of drive links in the chain, which correlates to the length of the chain. This ensures that the chain will properly loop around the saw's guide bar and drive sprocket.
Knowing these specifications ensures that the replacement saw chain will fit and function correctly with your saw's existing equipment, providing optimal performance and safety.
