Never operate a chain saw with a dull or damaged chain.
If the chain requires excessive pressure to cut or produces
dust instead of wood chips then inspect the cutters for dam-
age.
When sharpening the chain the objective will be to maintain
the same angles and profiles throughout its life as when it was
new.
Inspect the chain for damage or wear every time you refuel
your chain saw.
