Here's a quick guide to help you select the right chain:

Determine the chain pitch:

The pitch is the distance between the drive links on the chain. You can find this measurement by measuring the distance between any three rivets, then divide by two. Common pitches include ¼”, 3/8”, and .325”.

Determine the chain gauge:

The gauge is the thickness of the drive links. You can find this measurement by measuring the thickness of the drive link. Common gauges include .043”, .050”, .058”, and .063”.

The brand and the manufacturer's number might be stamped into the drive tooth, this can also indicate (when referenced with the manufacturer) the pitch and gauge measurements.

Determine the number of drive links:

The number of drive links depends on the length of your guide bar. Count the number of drive links on your old chain, or check your chainsaw owner's manual to find the correct number.

Determine the guide bar length:

The guide bar length is the distance from the chainsaw body to the tip of the guide bar. You can find this measurement listed on the guide bar itself with additional information containing pitch, gauge and links, or in the chainsaw owner's manual.

Match the specifications:

Once you have determined the pitch, gauge, number of drive links, and guide bar length, you can select a chainsaw chain that matches these specifications. Look for a chain designed for your chainsaw model and make.

Choose the right chain type:

Chainsaw chains come in a variety of types, including full chisel, semi-chisel, and low-profile chains. The type of chain you choose will depend on your cutting needs. Full chisel chains are best for cutting hardwoods, while semi-chisel chains are more versatile and can handle a range of cutting tasks. Low-profile chains are designed for smaller chainsaws and are best suited for light-duty cutting tasks.

Choosing the correct chainsaw chain involves determining the chain pitch, gauge, number of drive links, and guide bar length, and then selecting a chain that matches these specifications. Choosing the right chain type for your cutting needs is crucial. Always prioritise safety when operating a chainsaw, and consult with a professional if you have any doubts or questions.
