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 damage.
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.
