3 For your safety, and to maximize the service life of your
equipment, it is very important to take a few moments before you
operate the engine to check its condition. Be sure to take care of
any problem you find, or have your servicing dealer correct it,
before you operate the engine.
Improperly maintaining this engine, or failure to
correct a problem before operation, can cause a
malfunction in which you can be seriously hurt or
killed.
Always perform a preoperation inspection before
each operation, and correct any problem. The Oil Alert
system is designed to prevent engine damage
caused by an insufficient amount of oil in the crankcase. Before
the oil level in the crankcase can fall below a safe limit, the Oil
Alert
system will automatically stop the engine (the engine
switch will remain in the ON position).
If the engine stops and will not restart, check the engine oil level
(see page ) before troubleshooting in other areas.
Before beginning your preoperation checks, be sure the engine is
level and the engine switch is in the OFF position.
Always check the following items before you start the engine:
Look around and underneath the engine for signs of oil or
gasoline leaks.
Remove any excessive dirt or debris, especially around the
muffler and recoil starter.
Look for signs of damage.
Check that all shields and covers are in place, and all nuts, bolts,
and screws are tightened.
Check the fuel level (see page ). Starting with a full tank will
help to eliminate or reduce operating interruptions for refueling.
Check the engine oil level (see page ). Running the engine
with a low oil level can cause engine damage.
The Oil Alert
system (applicable types) will automatically stop
the engine before the oil level falls below safe limits. However,
to avoid the inconvenience of an unexpected shutdown, always
check the engine oil level before startup. The green indicator inside the
circuit protector will pop out to
show that the circuit protector has
switched off. If this occurs,
determine the cause of the
problem, and correct it before
resetting the circuit protector.
Push the circuit protector button
to reset.
Check the reduction case oil level on applicable types (see page
). Oil is essential to reduction case operation and long life.
Check the air filter element (see page ). A dirty air filter
element will restrict air flow to the carburetor, reducing engine
performance.
Check the equipment powered by this engine.
Review the instructions provided with the equipment powered
by this engine for any precautions and procedures that should
be followed before engine startup. The circuit protector protects the
battery charging circuit. A short
circuit, or a battery connected
with reverse polarity, will trip the
circuit protector.

7 Improper maintenance, or failure to correct a
problem before operation, can cause a malfunction in
which you can be seriously hurt or killed.
Always follow the inspection and maintenance
recommendations and schedules in this owner’s
manual.
To help you properly care for your engine, the following pages
include a maintenance schedule, routine inspection procedures,
and simple maintenance procedures using basic hand tools. Other
service tasks that are more difficult, or require special tools, are
best handled by professionals and are normally performed by a
Honda technician or other qualified mechanic.
The maintenance schedule applies to normal operating conditions.
If you operate your engine under severe conditions, such as
sustained high-load or high-temperature operation, or use in
unusually wet or dusty conditions, consult your servicing dealer
for recommendations applicable to your individual needs and use.
Some of the most important safety precautions follow. However,
we cannot warn you ofevery conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you
should perform a given task.
To ensure the best quality and reliability, use only new genuine
Honda parts or their equivalents for repair and replacement. Remember that an authorized Honda servicing dealer knows your
engine best and is fully equipped to maintain and repair it.To reduce the possibility of fire or explosion, be careful when
working around gasoline. Use only a nonflammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks and flames
away from all fuel related parts. Read the instructions before you begin, and make sure you have
the tools and skills required.Do not run the engine unless instructed to do so.
Let the engine and exhaust system cool before touching. Be sure there is adequate ventilation whenever you operate
the engine. Make sure the engine is off before you begin any maintenance
or repairs. This will eliminate several potential hazards:Failure to properly follow maintenance instructions
and precautions can cause you to be seriously hurt or
killed.
Always follow the procedures and precautions in this
owner’s manual. Good maintenance is essential for safe, economical and trouble-
free operation. It will also help reduce pollution.
Internal vent carburetor with dual element type only.
Cyclone type every 6 months or 150hours.
Replace paper element type only.
Cyclone type every 2 years or 600hours.
Service more frequently when used in dusty areas.
These items should be serviced by your servicing dealer,

8Oil is a major factor affecting performance and service life. Use
4-stroke automotive detergent oil.
Use 4-stroke motor oil that
meets or exceeds the
requirements for API service
classification SJ, SL, or
equivalent. Always check the
API service label on the oil
container to be sure it includes
the letters SJ, SL, 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. 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. Do not fill the fuel tank completely. Fill tank to
approximately 25 mm (1 inch) below the top of the fuel tank to
allow for fuel expansion. It may be necessary to lower the fuel
level depending on operating conditions. After refueling, tighten
the fuel tank cap securely.
Never refuel the engine inside a building where gasoline fumes
may reach flames or sparks. Keep gasoline away from appliance
pilot lights, barbecues, electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes environmental
damage. Wipe up spills immediately.
For information regarding oxygenated fuels, please refer to page
. Unleaded gasoline
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. Unleaded
gasoline produces fewer engine and spark plug deposits and
extends exhaust system life.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
Stop engine and keep heat, sparks, and flame away.
Refuel only outdoors.
Wipe up spills immediately.
Add fuel to the bottom of the fuel level limit of the fuel tank. Do
not overfill. Wipe up spilled fuel before starting the engine. With the engine stopped and on a level surface, remove the fuel
tank cap and check the fuel level. Refill the tank if the fuel level is
low.
Running the engine with persistent spark knock or pinging is
considered misuse, and the
Distributor’s Limited Warrantydoes
not cover parts damaged by misuse. Running the engine with persistent spark knock or pinging can
cause engine damage.
If spark knock or pinging occurs at a steady engine speed, under
normal load, change brands of gasoline. If spark knock or pinging
persists, see an authorized Honda servicing dealer. Occasionally you may hear a light ‘‘spark knock’’ or ‘‘pinging’’
(metallic rapping noise) while operatingunder heavy loads. This is
no cause for concern. Never use stale or contaminated gasoline or 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. U.S.
