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.

nStop the engine before setting the chain ten- sion.

nSlightly loosen the clutch cover lock knob by pressing in and rotating counterclockwise.

nHold the tip of the guide bar up and turn the chain tensioning dial 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.

nRetension 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 (UT10526 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.

CAUTION:

A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next use.
