SECTION 9: MAINTENANCE
WARNING: Disconnect the spark plug wire and ground against the 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 15. If you hit a foreign object or ice jam, the snow thrower is designed so that the shear bolts will shear.
If the augers will not turn, check to see if the hex bolts have sheared. Two replacement shear bolts and hex lock nuts have been provided with the snow thrower. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.
