SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, repairing, or inspecting, disengage all clutch levers and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.
Augers
The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. See Figure 16. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear.
Shear Bolts
