It is not necessary to remove the sprocket cover to
adjust the chain tension.
3. Turn the chain tension adjuster clockwise to
increase the chain tension.
4. Turn the chain tension adjuster counterclockwise to
decrease the chain tension.
5. When the chain is at the wanted tension, tighten the
sprocket cover nuts.
6. Pull the chain in the middle of the guide bar at the
bottom away from the bar. The gap between the
chain guide and the guide bar should be between 3
mm and 4 mm.
12.2 SHARPEN THE CUTTERS
Sharpen the cutters if it is not easy for the chain to go
into the wood.
We recommend that your dealer, which has an electric
sharpener, perform important sharpening work.
Figure 18-21.
1. Tensioning chain.
2. Sharpen the cutters corner with a 4.5 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.
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 5 mm.
•
There is too much space between the drive links
and the rivets.
•
The cut speed is slow
•
Sharpening the chain many times but it does not
increase the cutting speed. The chain is worn.

Make sure that it is turned over periodically to keep
symmetrical wear on the bar.

screw-driver, for example.
2. Clean the lubrication holes.
3. Remove burr from the edges and level the cutters
with a flat file.
Replace the bar if:
•
the groove is not fit with the height of the drive links
(which must never touch the bottom).
•
the inside of the guide bar is worn and make the
chain lean to one side.
