See «Technical Specifications» for the details which apply to your chain.
It is very difficult to file a chain saw correctly without the proper aids. We recommend the use of a file guide to ensure maximum cutting efficiency with the least tendency to kickback.
Filing cutters
To file cutters correctly, a ROUND FILE and a FILE GUIDE are required. Look under «Technical Specifications» for the correct file diameter and file guide for your saw and chain.
•File only with the chain properly tensioned. A loose chain wiggles, making it difficult to file.
•Always file from the inside of each cutter towards the outside. Lift the file on the return stroke.
•File the cutters on one side first. Then turn the saw around and file the cutters on the other side.
•Make certain that all cutters are of equal length. When the horizontal length is down to 3 mm (1/8"), the chain is worn out and must be discarded.
