•

Check that the oil channel in the bar is not obstructed. 
Clean if necessary.

•

Check that the oil channel in the gear housing is 
clean. Clean if necessary.

•

Check that the bar tip sprocket turns freely. If the chain 
lubrication system is still not working after carrying out 
the above checks you should contact your service 
workshop.

Check the chain daily for:

•

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.

When the length of the cutting teeth has worn down to 
only 4 mm the chain must be replaced.

Regularly check the degree of wear on the drive sprocket. 
Replace if wear is excessive.

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 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.
