SERVICING YOUR ENGINE
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 Honda servicing
dealer for recommendations applicable to your individual needs
and use.
Good maintenance is essential for safe, economical and trouble-
free operation. It will also help reduce pollution.
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.
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:
Some of the most important safety precautions follow. However,
we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you
should perform a given task.
Service more frequently when used in dusty areas.
Change engine oil every 25 hours when used under heavy
load or in high ambient temperatures.
These items should be serviced by an authorized Honda
dealer, unless the owner has the proper tools and is
mechanically proficient. See the Honda Shop Manual.
For commercial use, log hours of operation to determine
proper maintenance intervals.
Check that there is no crack and abnormal wear-out in the belt,
and replace if it is abnormal.
To perform maintenance on the lower part of the engine (Machine),
turn it 90° and lay it down with the carburetor/air cleaner always at
the top.
To ensure the best quality and reliability, use only new Honda
Genuine 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 non-flammable 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.

REFUELING

Unleaded gasoline
Research octane rating 91 or higher
Pump octane rating 86 or higher
This engine is certified to operate on unleaded gasoline with a
research octane rating of 91 or higher (a pump octane rating of 86
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.
Never use stale or contaminated gasoline or an oil/gasoline
mixture. Avoid getting dirt or water in the fuel tank.
Stop the engine and keep heat, sparks, and flame
away.
Refuel only outdoors.
Wipe up spills immediately.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when refueling.
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
tank cap and check the fuel level. Refill the tank if the fuel level is
low.
Add fuel to the upper level of the fuel tank. Wipe up spilled fuel
before starting the engine.
Refuel carefully to avoid spilling fuel. Do not overfill the fuel
tank (there should be no fuel in the fuel filler neck). It may be
necessary to lower the fuel level depending on operating
conditions. After refueling, tighten the fuel tank cap securely.
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 Warranty.
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.
