Stihl MS 461 Instruction Manual page 53

To sharpen the carbide-tipped saw
chain, use only the USG universal
sharpener with a diamond wheel. When
doing so, proceed according to the USG
Instruction Manual.
The angles must be identical for all
cutters in the saw chain. Varying angles:
Rough, uneven running of the saw
chain, increased wear – even to the
point of saw chain breakage.
All cutters must be equally long.
With varying cutter lengths, the cutter
heights also vary and cause rough
running of the saw chain and chain
breakage.
All cutters must be ground down
