SERVICING YOUR HONDA SNOWTHROWER
25
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 oil with
the “starburst” certification mark
displayed on the container.
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 or chipped. If
it is to be reused, clean the
electrode and insulator with a
wire brush.
NOTICE
Use only the recommended spark plugs or equivalent. Spark plugs
which have an improper heat range may cause engine damage.
