Saw chain sharpening
NOTE:
Never saw with a blunt chain. The saw chain is
blunt if you have to push the product into the tree and the
chips are very small.
Have your chain (3) sharpened professionally at an authorised
>
service centre or sharpen the chain yourself using a proper
sharpening kit. Also observe the sharpening instructions
supplied with the sharpening kit.
WARNING!
Only sharpen the saw chain yourself if you
are trained and have experience! Use proper tools to
sharpen the saw chain!
The height difference between the
>
tooth and the ridge is the cutting
depth. When sharpening the saw
chain (3) you have to consider the
following points (Fig. 50).
