5.
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 6 mm.
6.
When the chain is at the wanted tension, tighten
the lock nuts.
10.2 SHARPEN THE CUTTERS
Sharpen the cutters if chain does not go into wood
easily.
We recommend that a service center, which has
an electric sharpener, perform important sharpening
work.
1.
Tensioning chain.
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.
English
3-6 mm
NOTE
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 1/5 in. (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.
10.3 GUIDE BAR MAINTENANCE
Make sure that the bar is turned over periodically to
keep symmetrical wear on the bar.
1.
Lubricate the bearings on the nose sprocket (if
present) with the syringe (not included).
