Know your Chainsaw!

The ins and outs of chainsaws, the know how to know which chainsaw you are dealing with.

Length of the Chain

You need to know how long your chain is! The number of dive links determines the length of your chain, remember the chain stretches in its lifetime. The diagram shows the drive link, it is the tooth on the inside of the chain loop; it sits inside the groove of the guide bar. The easiest way to count them is to take the chain off the saw. Sometimes these drive links may have a code stamped into them,  this will vary by chain manufacturer but it will identify the chain type for you.

Chain Pitch

If there is no marking on the drive links you will need to work out the pitch of the chain. The pitch is the distance between three of the chain ‘rivets’ divided by two.

1/4″ is the smallest, 3/8″ is the most popular, 3/4” is the largest. The drive sprocket must be the same pitch as the chain.
