NOTICE:
Inspect the drive sprocket for wear or damage when replacing the chain. If
signs of wear or damage are present in the areas indicated, have the drive sprocket
replaced by qualified service technician.
How to Sharpen the Cutters
Be sure to file all cutters (Fig. 33) to the
specified angles and to the same length, as
fast cutting can be obtained only when all
cutters are uniform.
1. Remove the battery pack. Wear
gloves for protection.
2. Properly tension the chain prior to
sharpening. Refer to the chapter
"ADJUSTING THE CHAIN TENSION"
earlier in this manual.
3. Use a 5/32ʺ (4.0 mm) diameter
round file and holder (available
separately). Do all of your filing at
the middle position of the guide bar.
4. Keep the file level with the top plate
of the tooth. Do not let the file dip or
rock.
5. Keep a correct sharpening angle of
35° between the file and the saw
chain (see Fig. 34 & 35). Always use
a file holder (available separately)
when sharpening saw chains by
hand. File holders have markings for
the sharpening angle.
6. Using light but firm pressure,
perform a stroke towards the front
corner of the tooth. Lift the file away from the steel on each return stroke.
