SERVICING YOUR HONDA SNOWTHROWER
Scraper Bar
The scraper bar wears with normal use and must be replaced when it
reaches its service limit. The scraper bar 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 bar and
verify it contacts the ground
evenly. If not, adjust it.
3. Tilt the snowthrower back and
measure the thickness of the
scraper bar. Replace the
scraper bar if it less than 1/16
inch (2 mm) thick.
