MAINTENANCE SAFETY 
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.
SAFETY PRECAUTIONS
• Make sure the engine is off before you begin any maintenance or 
repairs. This will eliminate several potential hazards:
– Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate 
the engine.
– Burns from hot parts.
Let the engine and exhaust system cool before touching.
– Injury from moving parts.
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 nonflammable 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 genuine Honda 
parts or their equivalents for repair and replacement.
MAINTENANCE SCHEDULE 
(1)
For commercial use, log hours of operation to determine proper maintenance 
intervals.
(2)
Service more frequently when used in dusty areas.
(3)
Change engine oil every 25 hours when used under heavy load or in high ambient 
temperatures.
(4)
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.
*
See your equipment manual or Honda engine shop manual.
Failure to follow this maintenance schedule could result in non-warrantable failures.
REFUELING 
This engine is certified to operate on unleaded gasoline with 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 regular 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 warranty.
NOTICE
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 your 
DISTRIBUTOR’S LIMITED WARRANTY (see 
page 13).
Never use stale or contaminated gasoline or oil/gasoline mixture. 
Avoid getting dirt or water in the fuel tank.
Move at least 3 meters (10 feet) away from the fueling source and site 
before starting the engine.
Adding Fuel
1. Remove the fuel tank cap.
2. Add fuel to the bottom of the 
fuel level limit in the neck of 
the fuel tank. Do not overfill. 
Wipe up spilled fuel before 
starting the engine.
3. Secure the fuel tank cap.
a. Non-tether type:
Tighten the cap securely.
b. Tether type:
Tighten the cap until it 
clicks.
WARNING
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
