MAINTENANCE SCHEDULE
(1) Service more frequently when used in dusty areas.
(2) Change engine oil every 25 hours when used under heavy load or
in high ambient temperatures.
(3) 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.
(4) For commercial use, log hours of operation to determine proper
maintenance intervals.
REFUELING
Use unleaded gasoline with a pump octane rating of 86 or higher. This
engine is certified to operate on unleaded gasoline. Unleaded gasoline
produces fewer engine and spark plug deposits and extends exhaust
system life.

spill fuel when filling your fuel tank. Damage caused by spilled fuel is
not covered under the

ENGINE OIL
Recommended Oil
Use 4-stroke motor oil that meets
or exceeds the requirements for
API service classification SH, SJ,
or equivalent. Always check the
API service label on the oil
container to be sure it includes the
letters SH, SJ, or equivalent.
SAE 10W-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.
Oil Level Check
1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but
do not screw it in, then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark on the dipstick,
remove the oil filler cap/dipstick, and fill with the recommended oil
to the upper limit mark (bottom edge of the oil fill hole). Do not
overfill.
5. Reinstall the oil filler cap/dipstick.
Oil Change
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Place a suitable container
next to the engine to catch
the used oil
2. Remove the oil filler cap/
dipstick and the oil drain
plug.
3. Allow the used oil to drain
completely, then reinstall
the drain plug and washer.
Tighten the drain plug
securely.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw it in the trash or pour it on the ground or
down a drain.
4. With the engine in a level position, fill to the upper limit mark
(bottom edge of the oil fill hole) on the dipstick with the
recommended oil (see page 5).
