●
When the cutting edge has visible damage;
●
When the saw swings from side to side in the wood, this condition is caused by
uneven polishing of the chain or only one side is damaged.
Polish the chain frequently to remove only a small amount of material at a time, usually
with a file of two or three strokes.
---
Use a special round file for polishing the chain with a diameter of 4mm. Do not use a
normal round file.
---
The file should only be polished forward and in one direction. Do not make the file
touch the material when pulling back.
---
First polish the shortest saw blade and then unify the length of the blade with the
length of the other saw blades in the chain.
---
Operate the file as shown.
---
After finishing the chain polishing, rinse off the grinding dust and particles on the
chain.
Clean bar:
Debris and sawdust can build up in the guide sleeve, causing clogging and impeding the
supply of lubricating oil. Be sure to remove debris and sawdust when sanding or rep
lacing the chain.
