snug, but it can be turned by hand without binding.
Ensure that the chain brake is not set.
NOTE: If chain is too tight, it will not rotate. Loosen
the clutch cover lock knob by pressing in and
slightly rotating counterclockwise, then rotate the
chain tensioning dial counterclockwise. Lift the
tip of the guide bar up and retighten the clutch
cover lock knob securely. Ensure that the chain
will rotate without binding.
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.
 Slightly loosen the clutch cover lock knob by
pressing in and rotating counterclockwise.
 Turn the chain tensioning dial clockwise to ten-
sion 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 .050 in. out of the bar groove.
The tip of the supplied combination wrench
(UT10546, UT10566 and UT10586 only) 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.
MAINTENANCE
A chain tensioned while warm may be too tight
upon cooling. Check the "cold tension" before
next use to avoid possible injury.
