• Refuel only outdoors.
• Wipe up spills immediately.
Adding Fuel
See Figure 7, page 4
.
1. Remove the fuel tank cap.
2. Add fuel to the bottom of the fuel level gauge [1] in the neck of the
fuel tank. Do not overfill. Wipe up spilled fuel before starting the
engine.
3. Install the fuel tank cap and tighten it until it clicks.
Move at least 10 feet (3 meters) away from the fueling source and
site before starting the engine.
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.

ENGINE OIL

Oil is a major factor affecting performance and service life. Use
4-stroke automotive detergent oil. Always change the oil in
accordance with the maintenance schedule
Recommended Oil
See Figure 10, page 4.
Use 4-stroke motor oil that meets or exceeds the requirements for API
service category SJ or later. Always check the API service label on
the oil container to be sure it includes the letters SJ or later.
We recommend the use of Honda Genuine oil to maintain the
performance of the emission control system.
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.
Oil Level Check
See Figures 9, page 4.
1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick [1] and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but
do not screw it in, and then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark [2] on the
dipstick, remove the oil filler cap/dipstick, and fill with the
recommended oil to the upper limit mark [3]. Do not overfill.
5. Reinstall the oil filler cap/dipstick [1].

Oil Change
See Figures 9 and 11, page
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Turn the fuel valve to the OFF position to reduce the possibility of
fuel leakage.
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick [1] and drain the oil into the
container tilting the engine with the muffler side down, so the oil
drains out the oil filler neck [4].
Dispose of used motor oil in a manner that is compatible with the
environment. We suggest you take used oil in a sealed container to
your local recycling center or service station for reclamation. Do
not throw it in the trash, pour it on the ground, or pour it down a
drain.
4. With the engine in a level position, fill to the upper limit mark [3] on
the dipstick with the recommended oil.
Refill amount: 12.0 ~ 13.5 oz (0.35 ~ 0.40 L)
Always check the oil level with the dipstick after filling.
NOTICE
Running the engine with a low oil level can cause engine damage.
5. Reinstall the oil filler cap/dipstick [1] securely.

AIR CLEANER

A properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.
You will need to clean the filter more frequently if you operate the
engine in very dusty areas.
NOTICE
Operating the engine without a filter, or with damaged filter, will allow
dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered under your DISTRIBUTOR'S LIMITED
WARRANTY.
We recommend the use of a Honda Genuine air filter to ensure it
seals and performs as designed. Using a non-Honda air filter can
result in dirt bypassing the filter, causing damage to the engine or fuel
system.
Inspection
See Figure 13 page 5.
,
1. Press the latch tabs [1] on the top of the air cleaner cover [2], and
remove the cover. Check the filter [3] to be sure it is clean and in
good condition.
2. Reinstall the filter and air cleaner cover.
Cleaning
See Figure 13 page 5.
,
1. Tap the filter several times on a hard surface to remove dirt, or
blow compressed air not exceeding 30 psi (207 kPa) through the
filter from the clean side that faces the engine. Never try to brush
off dirt. Brushing will force dirt into the fibers.
2. Wipe dirt from the air cleaner body [4] and cover using a moist rag.
Be careful to prevent dirt from entering the air duct [5] that leads to
the carburetor.
