Sharpening the Chain
■■When the cutting edges of the blade become dull, they can be
■■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. Refer to adjustment procedures.
CAUTION!
Keep the chain sharp and properly adjusted.
WARNING!
The saw chain is very sharp. Wear gloves to protect your hands when work- ing with or around the saw chain.
Sharpening Instructions
IMPORTANT!
File all the 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.
2.After all cutters are sharpened, use
a depth gauge joiner (A) to measure the height of each depth gauge.
3.As required, lower the depth gauges to a height of 0.025 inch. Use a flat file.
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.
NOTE:
For consistent filing angles, use a filing guide.
NOTE:
See specification page for replacement bar and chain specs.
