Maintenance & Adjustments SB2040 Snowblower Maintenance & Adjustments Maintenance Schedule I When Notes E m t e chains Every two (2)hours use chainsaw oil Apply grease to antifriction ring As needed use general purpose grease Apply grease to bushings As needed use general purpose grease Apply grease to worm gear Inspect and adjust PTO spring tension As needed use general purpose grease adjust tension if needed Each use Adjustments You can be seriously injured by the fan or auger blades.
Maintenance & Adjustments SB2040 Snowblower Height Adjustment Lever Effort You may vary the amount of effort required to raise the blower head with the height adjustment lever. This is done by lengthening or shortening the exposed threads on the two counterbalance spring adjustment bolts. This balances the weight of the blower head against the springs, making the blower head easier (or harder) to lift with the height adjustment lever.
I Maintenance & Adjustments SB2040 Snowblower Other Maintenance Items Shear bolt Replacement The auger and discharge fan both have special shear bolts that are designed to break if either the auger or fan are put under an excessive load.
