• 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.
Checking wear on cutting equipment
Saw chain
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 5/32 inch (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.

GENERAL SAFETY PRECAUTIONS
Guide 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 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.
