ENGINE CARE
If major engine service or repair is required, contact
an authorized engine service center. The manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1.
Change the oil
after the first 5 hours of operation
and yearly or 100 hours thereafter under normal op-
erating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain bolt at base of the engine
and drain the oil into an approved container.
c. Remove the oil filter and dispose of it properly.
d. Before you install the new oil filter, clean the filter
mounting base and coat the seal of the new oil
filter will clean engine oil.
e. Install the oil filter by hand until the gasket
contacts the oil filter adapter, then tighten the oil
filter 1/2 to 3/4 turns.
f. Replace oil drain bolt making sure the sealing
washer is in place..
g. Remove oil cap plug and refill with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 57 to 58 ounces of oil
if it is completely drained. Use caution when refilling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when filling
the engine with oil to prevent overfilling.
h. Replace filler cap.
i. Start the engine up and warm it up.
j. After warming up the engine, recheck the oil
level and refill as necessary to bring it to the
proper level. See page 5 for proper oil level.

Make sure the engine is off before you begin any maintenance
or repairs. To prevent accidental startup, disconnect the spark
plug cap. This will eliminate several potential hazards:
Operate outside, away from open windows or doors.
Let the engine and exhaust system cool before touching.
Do not run the engine unless instructed to do so.
Read the instructions before you begin, and make sure you have
the tools and skills required.
To reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a non-flammable solvent,
not gasoline, to clean parts. Keep cigarettes, sparks and flames
away from all fuel related parts.
Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new Honda
Genuine parts or their equivalents for repair and replacement.
Service more frequently when used in dusty areas.
These items should be serviced by your Honda servicing
dealer, unless you have the proper tools and are mechanically
proficient. Refer to the Honda shop manual for service
procedures.
For commercial use, log hours of operation to determine
proper maintenance intervals.
Failure to follow this maintenance schedule could result in non-
warrantable failures.

engine has been running, allow it to cool first. Never refuel the
engine inside a building where gasoline fumes may reach flames
or sparks.
You may use unleaded gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol
must contain cosolvents and corrosion inhibitors. Use of fuels
with content of ethanol or methanol greater than shown above
may cause starting and/or performance problems. It may also
damage metal, rubber, and plastic parts of the fuel system. Engine
damage or performance problems that result from using a fuel
with percentages of ethanol or methanol greater than shown
above are not covered under the Warranty.
If your equipment will be used on an infrequent or intermittent
basis, please refer to the fuel section of the STORING YOUR
ENGINE chapter (see page
) for additional information
regarding fuel deterioration.
Spilled fuel is not only a fire hazard, it causes environmental
damage. Wipe up spills immediately.
Keep gasoline away from appliance pilot lights, barbecues,
electric appliances, power tools, etc.
Refuel in a well-ventilated area before starting the engine. If the
engine has been running, allow it to cool. Refuel carefully to avoid
spilling fuel. It may be necessary to lower the fuel level depending
on operating conditions. After refueling, tighten the fuel tank cap
securely.
Refer to the instructions provided with the equipment powered by
this engine for refuelling.
With the engine stopped and on a level surface, remove the fuel
filler cap and check the fuel level. Refill the tank if the fuel level is
low.
Never use stale or contaminated gasoline or an oil/gasoline
mixture. Avoid getting dirt or water in the fuel tank.
Fuel can damage paint and some types of plastic. Be careful not to
spill fuel when filling your fuel tank. Damage caused by spilled
fuel is not covered under the
Distributor’s Limited Warranty.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
