Checking wear on cutting equipment
A. Saw chain
Check the saw chain daily
for:
• Visible cracks in rivets
and links.
• Whether the chain is
stiff.
• Whether rivets and links
are badly worn.
Use a new chain to
compare the wear on the
old one.
When the length of the
cutting teeth has worn
down to only 4 mm the
chain must be replaced.
C. 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 one side of the bar tip
this is due to a slack
chain.
• To prolong the life of the
bar you should turn it
over daily.
