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.
When the length of the cutting teeth has worn down to only 4
mm the chain must be replaced.
Chain drive sprocket
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive.
Vibration damping system
Check regularly that the vibration damping element is free
from cracks. Check regularly the degree of wear to the rubber
dampers. Replace them if worn.
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 forms on the underside of the bar tip this is due to
running with a slack chain.
To prolong the life of the bar you should turn it over daily.
WARNING! A faulty cutting attachment may
increase the risk of accidents.
