How to sharpen your chainsaw chain

To sharpen your chainsaw chain you will require a chain filing guide, a depth gauge, a round file and a flat file. We stock a number of chainsaw sharpening kits to match numerous chain types. A chainsaw chain consists of two different teeth: a cutting tooth and a raker tooth – a small tooth which sits in front of the cutting tooth. The rakers job is to determine how much timber is to be cut by the cutting tooth.

Sharpening the cutting tooth:

1. Note where on the chain you start (In order not to sharpen the same tooth twice).
2. Take the chain brake off.
3. Place the filing guide over the chain so the cutting tooth is central to the guide.
4. Using a round file, file across the tooth three times directing the tooth away from you.
(Increase the amount of stroke across the tooth if the chain is very blunt)
5. Skip the next cutting tooth as it will need to be filed from the other side of the chainsaw. For every second cutting tooth repeat the same process.

Sharpening the raker tooth:

1. Place the depth gauge against the base and back of the cutting tooth and lay the gauge along the chain.
2. If the raker sticks through the gauge it needs to be filed down – simply run the flat file against the raker until it is inline with the depth gauge.
