SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Disconnect spark plug wire and ground against engine before performing any repairs or maintenance.
Augers
The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. See Figure 13. If you hit a foreign object or ice jam, the snow thrower is so designed that the bolts will shear.
•If the augers do not turn, check to see if the bolts have sheared and replace if necessary. Two replacement shear bolts (shown in Figure 13 inset) and hex lock nuts have been provided with the snow thrower. Please note that lock nuts cannot be threaded onto a bolt by hand. This type of nut is used where vibration occurs. So you will have to use a set of wrenches to tighten these hardware. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.
