BAR DRIVECASE COVER BAR NUT WARNING: Fig. 10 Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.
MAINTENANCE Place the bar onto the bar stud so that the chain tensioning pin fits into the chain tensioning pin hole. Fit the chain over the sprocket and into the bar groove. The cutters on the top of the bar should face toward the bar tip, in the direction of the chain rotation. Replace the drive case cover and reinstall the bar nut. Tighten the bar nut finger tight only; the bar must be free to move for tension adjustment.

Make sure the guide bar nut is loose to finger tight, turn the chain tensioning screw clockwise to tension the chain. Refer to Replacing the Bar and Chain for additional information. FLATS A cold chain is correctly tensioned when there is no slack on the underside of the guide bar and the chain is snug, but can be turned by hand without binding. Fig.
