Sharpening saw chain

Depending on the pitch of your chain, the diameter of the round file must be selected.
Read the label on the outside of the division of the depth.

Remove the value of the chain pitch in the table below.

Each partition is assigned a specific chain round files diameter. With your STIHL dealer you will find a selection of quality appropriate files.

Transfer the file by holding the handle with one hand and take with the other hand over the file on the forward stroke the tooth. Begin at the topping tooth and place the file in the incisor so that they can be guided to pressure from the inside to the outside of the incisor along.

Always file at a 90 ° angle to the guide rail. The file uses only the forward stroke - lift off file when returning. File rotate slightly at regular intervals in order to avoid a one-sided wear of the file.

STIHL saw chains are sharpened with standard 30 ° sharpening angle - parallel to the service marking the sharpening angle.

Run the file so that a quarter of the file diameter extends beyond the tooth roof.
File down the straightening teeth, until a perfect cutting edge is present.

Recognise reflections on the cutting edge of the tooth is not sharp.

Only when no reflections occur, you can be sure of a well sharpened tooth.
After you file all of the teeth to the same length, turn the saw around 180 ° and file all of the cutting teeth on the other side. Bring all the teeth to the length of the targeted tooth

The depth gauge is reduced when sharpening the saw tooth. Once all sharpened, you have to check the depth gauge and adjust if necessary.

Simply create the file gauge on the chain. It extends beyond the depth gauge on the doctrine, it must be reworked.

Depth-rework flush to file gauge.

With saw chains drive link, the hump is processed simultaneously with the depth gauge.

Be careful not to touch the freshly sharpenedtooth with a flat file. To increase the depth gauge is a low risk of kickback.
