Engine Oil Recommendations
Oil is a major factor affecting performance and service life. Use
4-stroke automotive detergent oil. Always change the oil in
accordance with the
MAINTENANCE SCHEDULE
(
page 11
).
Recommended oil for general use:
SAE 5W-30
Other viscosities shown in the
chart may be used when the
average temperature in your
area is within the
recommended range.
The SAE oil viscosity and
service classification are in the
API label on the oil container.
Honda recommends API
service category SJ or later oil.
Spark Plug
Replace the spark plug every 150 hours of use.
Recommended Spark Plug: NGK - BPR5ES
NOTICE
An incorrect spark plug can cause engine damage.
For good performance, the spark
plug must be properly gapped and
free of deposits.
1. Allow the engine to cool, open
the spark plug access panel,
and 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 or chipped.
3. Measure the spark plug
electrode gap with a suitable
gauge.
Gap: 0,7 ~ 0,8 mm
Correct the gap, if necessary,
by carefully bending the side
electrode.
4. Install the spark plug carefully,
by hand, to avoid cross-threading.
5. After the spark plug seats, tighten with a spark plug wrench to
compress the washer.
If reinstalling the old spark plug, tighten 1/8 to 1/4 turn after the
spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats.
NOTICE
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
6. Install the spark plug cap on the spark plug and close the spark
plug access cover.
Auger
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.
2. 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 in the cable
length
– Moving the cable
makes a 10 mm
change in the cable
length
3. Slide the cover back
over the spring.
Belt Tension
Inspection
Pull the spring cover [1] up
to expose the belt tension
spring. Have a helper
engage the auger clutch
lever. Measure the length of
the exposed clutch spring
coils.
CLUTCH SPRING
LENGTH: 75 ~ 80 mm
Adjustment
Remove the z-bend fitting
from the lower hole on the
auger clutch lever and install
it into the upper hole [2].
Recheck the spring length.
