The depth gauge setting becomes smaller when the cutter is sharpened.
After sharpening the cutters, check the depth gauge setting and lower it if necessary.
Check the depth gauge setting with a filing gauge that matches the chain pitch.
Place the file gauge on the saw chain. If the depth gauge is higher than the filing gauge, it must be lowered.
Remove the filin gauge from the chain and then file down the depth gauge until it is level with the filing gauge.
File the top of the depth gauge parallel to the service mark - but do not lower the highest point of the depth gauge in this process. Take care not to touch the freshly sharpened cutter with the flat file.
