Cooling System - Husqvarna 565 Operator's Manual

To examine the cutting equipment for
wear
Do a visual check of the saw chain daily.
1. Make sure that there are no visible cracks in rivets
and links.
2. Examine wheather the saw chain is stiff.
3. Compare the existing saw chain with a new saw
chain to decide wheather the rivets and links are
badly worn.
4. Replace the saw chain if it exhibits any of the
conditions above.
5. Replace the saw chain when the length of the cutting
teeth has worn down to only 4 mm.
To do a check of the guide bar
Do a check of the guide bar regularly.
1. Examine whether there are burrs on the edges of the
bar. Remove burrs with a file if necessary.
2. Examine whether the groove in the bar has become
badly worn. Replace the bar if necessary.
3. Examine 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.
