specification when the holders are installed with the three holes
facing up.
Replacement
The scraper must be replaced if it is worn abnormally or the service
limit is exceeded.
1. Turn the engine switch off and drain the fuel tank.
2. Lift the handle so that the auger housing faces down.

scraper, and remove the scraper.
4. Install a new scraper into the auger housing securely.
5. Install the self-locking nuts, collars and holders, then tighten the self-
locking nuts securely.
Check that all holders are installed in the same direction.
Be sure that there is no clearance between the scraper and ground
when the snowthrower is placed on the ground, and that the auger
rubber-to-ground clearance is correct, then tighten the self-locking
nuts.
Correct clearance: 0 2 mm (0 0.079 in)
