Auger Paddle

Inspection

The paddles are thick, rubber parts bolted to the edges of the auger. 
The paddles are subject to wear, and should be inspected and 
replaced if worn beyond the service limit.

1. Park the snow blower on a flat, 

level surface. Disconnect the 
spark plug cap and turn the 
fuel valve OFF so the engine 
cannot be accidentally started. 
Tilt the snow blower back 
enough to raise the auger 
housing.

2. Inspect the paddles on the 

auger and make sure they are in good condition and securely 
attached.

3. Measure the distance 

between the edge of the 
rubber paddle to the edge of 
the metal auger support.

AUGER PADDLE SERVICE 
LIMIT: 
5/8 in (15 mm)

Auger paddle replacement 
should only be done by a 
servicing Honda snow blower 
dealer. If the paddles are worn 
out, the scraper blade may also 
need replacement.

Scraper Blade

Inspection

1. Turn the engine switch and fuel valve 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 

"Adjustment"

 

below.

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 in (1 ~ 3 mm)

If the ground clearance is 
not within the 
specification, adjust the 
scraper blade. See 

Adjustment 

on this page

.

4. Tilt the snow blower back 

and measure the 
thickness of the scraper 
blade. Replace the 
scraper blade if it is less 
than 1/16 in (2 mm) thick. 
See 

Replacement

 on this 

page.

Adjustment

1. Turn the engine switch and 

fuel valve to the OFF 
position and disconnect the 
spark plug cap so the 
engine cannot be 
accidentally started. 

2. Tilt the snow blower 

forward to provide access 
to the underside of the 
scraper blade.

3. Loosen (don’t remove) the 

three flange nuts on the 
scraper blade. 

4. Move the scraper blade 

down slightly. Tighten the 
self-locking nuts and recheck the clearance. 

Repeat the procedure as needed to get the necessary clearance. If 
you cannot set the ground clearance within 1/16 ~ 1/8 in, replace 
the scraper blade.

Replacement

The scraper blade wears with normal use and must be replaced when 
it reaches the service limit. The scraper blade thickness and 
adjustment determine the clearance between the rubber paddles and 
the ground.
A new scraper blade can be purchased from a servicing Honda 
dealer. See 

page 20

 for scraper blade and hardware part numbers.

1. Turn the engine switch and fuel valve to the OFF position (

page 7

and disconnect the spark plug cap so the engine cannot be 
accidentally started.

2. Tilt the snow blower forward to provide access to the underside of 

the scraper blade.

3. Remove the three flange nuts, flat washers, and the scraper blade.

4. Install the new scraper blade, reusing the bolts, washers, and nuts.

5. Adjust the scraper blade. See 

Adjustment
