MAINTENANCE

nReplace the chain cover, washer and chain cover screw. Tighten the chain cover screw finger tight only. The bar must be free to move for tension adjustment.

nRemove all the slack from the chain by turning the chain tensioning screw clockwise until the chain seats snugly against the bar with the drive links in the bar groove.

nLift the tip of the guide bar up to check for sag. Release the tip of the guide bar and turn the chain tensioning screw 1/2 turn clockwise. Repeat this process until sag does not exist.

nHold the tip of the guide bar up and tighten the bar mount- ing screw securely.

nChain is correctly tensioned when there is no sag on the underside of the guide bar, the chain is snug, but it can be turned by hand without binding.

NOTE: If chain is too tight, it will not rotate. Loosen the chain cover screw slightly and turn tension adjuster 1/4 turn counterclockwise. Lift the tip of the guide bar up and retighten chain cover screw securely. Assure that the chain will rotate without binding.

nPlace the hex key back into the storage area.

CHAIN TENSION

See Figures 30 - 31.

nStop the engine before setting the chain tension. Make sure the guide bar screw is loosened to finger tight, turn the chain tensioner clockwise to tension the chain. Refer to “Replacing the Bar and Chain” earlier in this manual for additional information.

A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug, but it can be turned by hand without binding.

nChain must be re-tensioned whenever the flats on the drive links hang out of the bar groove.

nDuring normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately .050 in. (1.25 mm) out of the bar groove.

NOTE: New chain tends to stretch, check chain tension frequently and tension as required.

CAUTION:

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