Maintenance Schedule

(1) These parts may require more frequent inspection and replacement under heavy use.
(2) These items should be serviced by an authorized Honda servicing dealer unless you have the proper tools and are mechanically 

proficient. Refer to the Honda shop manual for service procedures. See “Honda Publications” on 

page 20

 for ordering information.

Failure to follow this maintenance schedule could result in non-warrantable failures.

Oil Change

Change the oil after the initial 5 hours of use. Thereafter, change the 
oil every 6 months or 50 hours of use. Change the oil more frequently 
when used under heavy load. See “Engine Oil Recommendations” o
the following page for recommended oil properties.

Drain the used oil while the engine is warm. Warm oil drains quickly 
and completely.

1. Place the snow blower on a level surface.
2. Place a suitable container below the drain bolt to catch the used 

oil, and then remove the oil filler cap/dipstick and the drain plug.
Allow the oil to drain completely.

3. Reinstall the drain plug using a new drain plug washer.
4. After draining, take the oil to your local recycling center or service 

station. Do not throw it in the trash, pour it on the ground, or pour 
it down a drain.

5. With the engine in a 

level position, fill 
with the 
recommended oil. 
Do not overfill. Allow 
a couple of minutes 
for the oil to settle in 
the engine, and 
then measure the oil 
level (

page 5

). 

NOTICE

Using nondetergent 
oil can shorten the 
engine’s service life, 
and using 2-stroke 
oil can damage the 
engine.

6. Screw in the oil filler 

cap/dipstick 
securely.
