How to use

Select the file size that matches your chain's specifications, secure the chainsaw or chain in a stable position and follow the cutter’s angle when sharpening.

Count strokes to keep both sides uniform and check the depth gauges and overall tooth profile regularly. After sharpening, remove filings and test the chain on wood at low speed before regular use.

Use appropriate personal protective equipment—gloves and eye protection—when sharpening chains. Maintain the correct filing angle and pressure to avoid over-filing. Combine regular sharpening with periodic professional maintenance and replacement of worn components to ensure safe and efficient saw operation.
