CHAINSAW PARTS ADVICE - CHAIN & BARS
Chainsaw chain cutter depth gauge
If your chainsaw chain is not cutting properly but the cutters look and feel sharp you will probably need to file a bit off the rakers which are just in front of the cutting edge and keep the cutters from taking to much wood .
The rakers over time will end up sticking up too high as the tooth gets filed down and back. A quick check to see how sharp your chainsaw chain is would be to lightly brush the top of your fingernail across the point of the cutter and if it cuts into the nail a little it is sharp.
The depth gauge fits over the chainsaw chain similar to the file guide but only has a slot for the raker to protrude through. Using a flat file you file the raker flush with the gauge. The depth gauge as with the file guide must be matched to your saw chain to the manufacturers specifications. It is important to get this correct because if you take to much off, your chainsaw will be chattering and hard to hang on to when cutting. This can be dangerous and if you take to little the chain will cut as if it is dull.
