Visible cracks in rivets and links. Whether the chain is stiff. Whether rivets and links are badly worn.
We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. � Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
