 Turn the chain tensioning screw clockwise until
the flats on the tie straps of the chain contact
the bar, making sure the drive links are seated
inside the bar groove.
 Retighten the bar mounting nuts securely.
 Release the tip of the guide bar and verify the
chain is now correctly tensioned using the
guidelines above.
NOTE: If the chain is too tight and will not
rotate, loosen the chain cover screw slightly,
then turn the chain tensioning screw 1/4 turn
counterclockwise. Lift up the tip of the guide bar,
retighten the chain cover screw securely, then
verify the chain will now rotate without binding.
NOTE: New chains tend to stretch; check the
chain tension frequently and tension as required.
NOTICE:
A chain tensioned while warm may be too tight
upon cooling. Check the "cold tension" before
next use to avoid possible injury.
