Scraper Blade - Honda HS520A Owner's Manual

SCRAPER BLADE

The scraper blade wears with normal use and must be replaced when
it reaches its service limit. The scraper blade thickness and adjustment
determine the clearance between the rubber paddles and the ground.
Inspection
1. Turn the engine switch to the OFF position and disconnect the
spark plug cap so the engine cannot be accidentally started.
2. Examine the scraper blade and verify it contacts the ground evenly.
If it does not, adjust the scraper blade. See "Scraper blade
adjustment" on page 30.
3. Measure the distance between
the ground and lowest point on
the rubber paddle on the auger.
The paddle ground clearance
should be 1/16 ~ 1/8 inches
(1 ~ 3 mm).
If the ground clearance is not
within the specification, adjust
the scraper blade. See "Scraper
blade adjustment" on page 30.
4. Tilt the snowthrower back and
measure the thickness of the
scraper blade. Replace the
scraper blade if it is less than
1/16 inch (2 mm) thick. See
"Scraper blade replacement" on
page 30.
