NOTE
It is not necessary to remove the chain cover to adjust
the chain tension.
2. Turn the chain tension screw behind the bar and
chain clockwise to increase the chain tension.
3. Turn the chain tension screw counterclockwise to
decrease the chain tension.
4. When the chain is at the wanted tension, tighten the
chain cover.
9.2 SHARPEN THE CUTTERS
Sharpen the cutters if chain does not go into wood
easily.
NOTE
We recommend that a service center, which has
an electric sharpener, perform important sharpening
work.
1. Clamp Bar.
2. Sharpen the cutters corner with a 5/32 in. (4 mm)
diameter round file .
3. Sharpen the top plate, side plate and depth gauge
with a flat file.
4. File all the cutters to the specified angles and the
same length.
NOTE
During the process:
• Keep the file flat with the surface to be sharpened.
• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the
surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to
the other side.
Replace the chain if:
• The length of the cutting edges is less than 1/5 in. (5
mm).
• There is too much space between the drive links
and the rivets.
• The cut speed is slow.
