Replacing the Scraper
Before each season, inspect the scraper for wear. If the
thickness of the scraper bottom is less than 1/16”
(0.16 cm), replace the scraper (Fig. 10).

Note: The running time and the roughness of the driveway
or the sidewalk determines the scraper wear rate.
1. Stop the engine and wait for all moving parts to stop.
2. Drain gasoline from fuel tank; refer to Emptying the
Fuel Tank on page 11.
3. Tip snowthrower forward onto its front housing.
4. Remove three carriage bolts and three flange nuts that

bolts and flange nuts. Position the bolt heads on the
inside of the housing (Fig. 11).
Replacing the Drive Belt
Inspect the drive belt before each season, and replace it if
it is worn or damaged. After extended use, the drive belt
may wear and require replacement. If, after adjusting the
control bar, the drive belt continues to slip under a heavy
load or the rotor does not turn, check to see if the belt is
severely worn.
1. Stop the engine and wait for all moving parts to stop.
2. Drain gasoline from fuel tank. Refer to Emptying the
Fuel Tank on page 11.
3. Tip the snowthrower on its right side.
4. Remove three self tapping screws, three capscrews, a
washer, and three nuts that secure the left side cover to
the snowthrower frame (Fig. 12).

the cable.
6. Slip the belt off the idler pulley (Fig. 13).
7. Move the idler pulley and slip the belt from the rotor
pulley, the idler pulley, and the engine pulley.
8. Loop the belt around the rotor pulley and the engine
pulley first without slipping the belt between the rotor
pulley and the brake.
9. Move the idler pulley and slide the belt between the
rotor pulley and the brake arm (Fig. 13).
10. Release the idler pulley, and slip the belt under the
idler pulley (Fig. 13)
