Tools required:    4 mm (5/32 in.) Round File, Flat File, Depth Gauge        

 

 

 

 

Dull or damaged cutters will result in poor cutting performance, 

increased vibration, and premature saw chain failure.

Always stop engine and disconnect spark plug wire before servic-

ing guide bar and saw chain. Always wear gloves when filing saw 

chain, otherwise serious personal injury may result.

1.  Set round file (A) in cutter at 30° angle. One fifth (1/5) of the file 

should be exposed above top cutter edge.

2.  Keep file horizontal in cutter and file in one direction.

3.  File until cutter top and side bevel edges are sharp without nicks.

4.  Place depth gauge tool (B) firmly on top of cutter with .025 in. slot 

and  end against front cutter raker. File cutter raker with flat file 

until flush with top of depth gauge.

5.  Finish cutter sharpening by rounding front raker edge (C) with flat 

file.

6.  Properly filed cutter is as shown.

7.  Apply clean oil and rotate saw chain slowly to wash away filings.

8.  If saw chain is coated or clogged with resin, clean in kerosene, 

then soak in oil.
