Checking wear on cutting equipment
Saw chain
Li-ion
Li-ion
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.

GENERAL SAFETY PRECAUTIONS
•
If the guide bar groove is abnormally worn or can be
turned backwards and forwards on the shaft an
abnormal amount. 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.
