740, 840 & 840G Snowblowers
OPERATING INSTRUCTIONS – cont’d.
9.Periodically check all bolts for tightness. The bolt holding on the fan and the bearing bolts are of particular importance.
10.Danger: Always stop blower for servicing or unplugging. The PTO should be disengaged before dismounting from the tractor.
11.CAUTION: Always check to see that both ends of the PTO shaft are securely attached as per instructions every time you are preparing to use the snowblower.
12.Shear Sprocket: The Shear Sprocket (#52) should be checked at the beginning of every season to make sure it will spin freely. With time this sprocket could corrode and seize which will not allow the shear bolt to break if something jams in the snowblower auger. Clean to loosen if necessary.
13.When replacing bearings or tightening a loose bearing collar, always tighten collar in the direction of shaft rotation using a center punch or a similar tool.
