ENGINE CARE
MAINTENANCE SCHEDULE
If major engine service or repair is required, contact an
authorized engine service center. The manufacturer of
these engines has established an excellent world-wide
engine service organization. Engine service is very likely
available from a nearby authorized dealer or distributor.
CHECKING THE OIL LEVEL
The oil level must always be checked before the engine is
started. Refer to page 5 of this manual for instructions on
checking the oil level. Take care to remove any dirt or debris
from around the oil plug before removing. Be sure the oil
level is maintained.
CHANGING THE OIL
Refer to the Maintenance Schedule Chart for required oil
change intervals.
Outdoor temperatures determine the proper oil viscosity for
the engines. Winco recommends our 5W-30 fully synthetic
oil to give you excellent protection in cold temperatures
while maintaining excellent performance in warmer
weather.
A. Start the engine and warm it up, stop the engine and
remove the spark plug wire to prevent it from
accidentally being started.
B. This engine has an oil drain valve for your convenience.
Attach a neoprene hose and drain the oil into an
approved
container.

MAINTENANCE SCHEDULE
REFUELING
Recommended Fuel
7
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.
Unleaded gasoline
U.S.
Except U.S.
Pump octane rating 86 or higher
Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline with a
pump octane rating of 86 or higher (a research octane rating of 91
or higher).
Refuel in a well ventilated area with the engine stopped. If the
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.
Stop the engine and keep heat, sparks, and flame
away.
Refuel only outdoors.
Wipe up spills immediately.
Replace the paper filter element only.
Refer to the Shop Manual.

Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear.
This type of damage is not covered by the Distributor’s Limited
Warranty.
Remove the air cleaner cover and inspect the filter elements.
Clean or replace dirty filter elements. Always replace damaged
filter elements.
Pull the air cleaner cover latch to the unlocked position, and
remove the cover.
Remove the paper filter element and foam filter element from
the air cleaner case.
Inspect both filter elements, and replace them if they are
damaged. Always replace the paper filter element at the
scheduled interval (see page
).
A dirty air cleaner will restrict air flow to the carburetor, reducing
engine performance. If you operate the engine in very dusty areas,
clean the air filter more often than specified in the MAINTENANCE
SCHEDULE (see page ).
Remove the wing nut from the paper filter element.
Drain the engine oil, and retighten the drain bolt securely.
Remove the oil filter, and drain the oil into a suitable container.
Dispose the used oil and filter in a manner compatible with the
environment.
Use an oil filter socket, rather than a strap wrench, to avoid
striking and damaging the oil pressure switch.
Clean the filter mounting base, and coat the seal of the new oil
filter with clean engine oil.
Use only a Honda Genuine oil filter or a filter of equivalent
quality specified for your model. Using the wrong filter, or a
non-Honda filter which is not of equivalent quality, may cause
engine damage.
Oil filter tightening torque:
Refill the crankcase with the specified amount of the
recommended oil (see page ). Reinstall the oil filler cap and oil
level dipstick.
Start the engine, and check for leaks.
Stop the engine, and check the oil level as described on page .
If necessary, add oil to bring the oil level to the upper limit mark
on the oil level dipstick.
Screw on the new oil filter by hand until the seal contacts the
filter mounting base, then use an oil filter socket tool to tighten
the filter an additional 3/4 turn.
