Oil Level Check
See F2, F3 on page 2.
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.
Oil Change
See F3 on page 2.
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 by tipping the engine toward 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: 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 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.
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.
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.
Inspection
See F4 on page 2.
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 F4 on page 2.
1. Tap the filter several times on a hard surface to remove dirt, or
blow compressed air not exceeding 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.

SPARK PLUG

See F5 on page 2.
Required Spark Plug:
NGK - BPR5ES All other applications
The required spark plug is the correct heat range for normal engine
operating temperatures.
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
1. Disconnect the cap from the spark plug, and remove any dirt from
the spark plug area.
2. Use the proper size spark plug wrench [1] to remove the spark
plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the
sealing washer [2] is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a suitable gauge. The correct gap
is 0.70 ~ 0.80 mm. If adjustment is needed, correct the gap by
carefully bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug is seated, tighten with the proper size spark
plug wrench to compress the washer.
When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8 ~ 1/4 turn
after the spark plug seats to compress the washer.
NOTICE
Properly tighten the spark plug. A loose spark plug can become
very hot and can damage the engine. Overtightening the spark
plug can damage the threads in the cylinder head.
7. Attach the spark plug cap to the spark plug.

FLYWHEEL BRAKE INSPECTION

See F6 on page 2.
Check the flywheel brake lever clearance. If it is less than 2 mm, take
the engine to your authorized Honda servicing dealer.
