Checking wear out on cutting equipment
Chain:
Visible cracks in rivets and links
Whether the chain is stiff.
Whether rivets and links are badly worn.
Replace the saw chain if it exhibits any of the points above.
We recommend you compare the existing chain with a new chain to decide how badly the
existing chain is worn.
When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
Bar:
Check regularly:
Whether there are burrs on the edges of the bar.
Remove these with a file if necessary.
Whether the groove in the bar has become badly worn.
Replace the bar if necessary.
Whether the tip of the bar is uneven or badly worn. If a
hollow form on the bottom side of the bar tip, due to
running with a slack chain.
To prolong the life of the bar you should turn it over daily.
