ADJUSTING THE CHAIN TENSION
See Figures 43 - 45.
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 tension.
Make sure the bar mounting nuts are loosened
to finger tight.
Turn the chain tensioning screw clockwise to
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
tie straps hang out of the bar groove.
NOTE: During normal saw operation, the tem-
perature of the chain increases. The tie straps
of a correctly tensioned warm chain will hang
approximately .050 in. out of the bar groove.
The tip of the 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.
