Engine Oil Recommendations
Oil is a major factor affecting performance and service life. Use a
high quality 4-stroke automotive detergent oil.
SAE 5W-30 is
recommended for general
use. Other viscosities shown
in the chart may be used
when the average
temperature in your area is
within the indicated range.
The SAE oil viscosity and
service classification are on
the API label on the oil container. Honda recommends that you use
API service category SJ or later oil or equivalent.

SPARK PLUG SERVICE

To ensure proper engine operation, the spark plug must be properly
gapped and free of deposits.
1. Open the spark plug access
panel, then remove the
spark plug cap. Use a
commercially available
spark plug wrench or socket
to remove the spark plug.
2. Inspect the spark plug.
Replace it if the electrodes
are worn or if the insulator is
cracked, chipped, or fouled
with deposits. Make sure
that the spark plug washer
is in good condition.
NOTICE
Use only the recommended spark plugs or equivalent. Spark plugs
which have an improper heat range may cause engine damage.
A replacement spark plug may be purchased from a servicing Honda
snowthrower dealer.
SPARK PLUG: BPR5ES (NGK) or W16EPR-U (DENSO)
3. Measure the plug gap with a
feeler gauge. Correct as
necessary by bending the side
electrode.
PLUG GAP: 0.70 ~ 0.80 mm
4. Thread the spark plug in by hand
to prevent cross-threading.
5. After the spark plug is seated,
tighten with a spark plug wrench
to compress the washer.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug,
tighten 1/8 to 1/4 turn after the spark plug seats.
NOTICE
The spark plug must be securely tightened. An improperly
tightened spark plug can become hot and may damage the engine.
6. Connect the spark plug cap.
7. Close the spark plug access panel.

Clutch Lever Free Play
Inspection
Move the clutch lever until
you feel resistance from the
cable. Measure the distance
as shown.
CLUTCH LEVER
DISTANCE:
190 ~ 205 mm
Adjustment
1. Pull the spring cover [1]
up to expose the tension
spring. Change the
position of either the
cable or spring on the
metal plate so the clutch
lever distance is correct.
Moving the spring makes
a 6 mm change, while
moving the cable makes
a 10 mm change in the
length of the cable.
2. Slide the cover back over
the spring.
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 snowthrower on a flat,
level surface.
2. Disconnect the spark plug cap
and turn the fuel valve OFF.
3. Tilt the snowthrower back
enough to raise the auger
housing.
4. Inspect the paddles on the
auger and make sure they are
in good condition and securely
attached.
5. Measure the distance between
the edge of the rubber paddle to the edge of the metal auger
support.
AUGER PADDLE SERVICE LIMIT: 15 mm
Auger paddle replacement should only be done by a servicing Honda
snowthrower dealer. If the paddles are worn out, the scraper blade
may also need replacement (page 10).
