MAINTENANCE
Sharpening the Chain
When the cutting edges of the blade become dull, they can be re- sharpened with a few strokes of a file.
In order to keep the blade in balance, all cutting edges must be sharpened equally.
In addition, inspect the chain for correct adjustment (more frequently with a new chain). The chain should feel snug but still pull freely. See Figure 36. Refer to page 16 for adjustment procedures.
Sharpening Instructions (Fig.37)
IMPORTANT!
File all cutters to the same angle and depth! Unequal filing may cause the saw to vibrate or cut erratically!
1.Using a 4.5 mm round file, sharpen all cutters to a 30° angle. Make sure that one fifth (20%) of the file’s diameter is always held above the cutter’s top plate.
NOTE:
For consistent filing angles, use a filing guide such as Oregon® p/n 31692 or equivalent.
2.After all cutters are sharpened, use a depth gauge joiner (Oregon® p/n 106738 or equivalent) to measure the height of each depth gauge.
3.As required, lower the depth gauges to a height of 0.020 inch. Use a flat file; (Oregon® p/n 12211 or equivalent).
4.After all depth gauges have been adjusted, use a flat file to round each depth gauge leading edge to its original curvature and angle.
