GENERAL SAFETY PRECAUTIONS
Checking wear on cutting equipment
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 4
mm (0,16 inch) the chain must be replaced.
Chain drive sprocket
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive.
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.
