ADJUSTING THE CHAIN TENSION
See Figures 44 - 46.
WARNING:
Never touch or adjust the chain while the engine
is running. The saw chain is very sharp. Always
wear protective gloves when performing main-
tenance on the chain.
 Stop the engine before setting the chain ten-
sion.
 Make sure the bar mounting nuts are loosened
to finger tight.
 Turn the chain tensioning screw clockwise to
increase tension the chain.
NOTE: A cold chain is correctly tensioned when
there is no slack on the underside of the guide
bar, the chain is snug, and it can be turned by
hand without binding.
 Retension the chain whenever the flats on the
drive links hang out of the bar groove.
NOTE: During normal saw operation, the tem-
perature of the chain increases. The drive links
of a correctly tensioned warm chain will hang
approximately 0.050 in. out of the bar groove.
The tip of the supplied combination wrench can
be used as a guide to help determine the correct
warm chain tension.
NOTE: New chains tend to stretch; check
the chain tension frequently and tension as
required.
CAUTION:
A chain tensioned while warm may be too tight
upon cooling. Check the "cold tension" before
next use to avoid possible injury.
