Scraper
If the scraper is deformed or improperly adjusted, the snowthrower
will not clear the snow evenly.
REPLACEMENT INTERVAL:
Replace the scraper every 5 years, or whenever the auger rubbers are
replaced. Replace the scraper also if it becomes too deformed to clear
the snow evenly.
To prevent accidental starting, turn the engine switch to the OFF
position and disconnect the spark plug cap.
Inspection
1. Place the snowthrower on a level ground.
2. Measure the thickness of the scraper.
Replace the scraper if its thickness is less than:
2 mm (0.079 in)
3. Measure the auger rubber-to-ground clearance.
It should be:
0 2 mm (0 0.079 in) − −
If the clearance is out of the specification, adjust the scraper (see
page. 41 ).
0 2 mm (0 0.079 in) − −
