Every season lubricate the auger bearings and the bearings on the side of the frame with light oil. See Figure

Drive and Shifting Mechanism
Lubricate at least once a season or after 25 hours of operation. Remove the rear cover, lubricate any chains,

other components as a result of doing so will not be covered by your snow thrower’s warranty.
