To examine the cutting equipment
1. Make sure that there are no cracks in rivets and
links and that no rivets are loose. Replace if it is
necessary. (Fig. 148)
2. Make sure that the saw chain is easy to bend.
Replace the saw chain if it is rigid.
3. Compare the saw chain with a new saw chain to
examine if the rivets and links are worn.
4. Replace the saw chain when the longest part of the
cutting tooth is less than 4 mm/0.16 in. Also replace
the saw chain if there are cracks on the cutters. (Fig.
149)
To do a check of the guide bar
1. Make sure that the oil channel is not blocked. Clean
if it is necessary. (Fig. 144)
2. Examine if there are burrs on the edges of the guide
bar. Remove the burrs using a file. (Fig. 150)
3. Clean the groove in the guide bar. (Fig. 145)
4. Examine the groove in the guide bar for wear.
Replace the guide bar if it is necessary. (Fig. 151)
5. Examine if the guide bar tip is rough or very worn.
(Fig. 152)
6. Make sure that the bar tip sprocket turns freely and
that the lubricating hole in the bar tip sprocket is not
blocked. Clean and lubricate if it is necessary. (Fig.
