Oil Change
Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
OIL FILLER NECK
1. Turn the fuel valve to the OFF position to reduce the possibility of
fuel leakage (see TYPE 1 Step 1 on page 2).
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick and drain the oil into the container
by tipping the engine toward the oil filler neck.
Please 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
down a drain.
4. With the engine in a level position, fill to the upper limit mark on the
dipstick with the recommended oil (see above).
NOTICE
Running the engine with a low oil level can cause engine damage.
5. Reinstall the oil filler cap/dipstick securely.
AIR CLEANER
A dirty air cleaner will restrict air flow to the carburetor and cause poor
engine performance. Inspect the filter each time the engine is
operated. 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 (see
page 13).
Inspection
AIR CLEANER BODY
1. Press the latch
tabs on the top of
the air cleaner
cover, and remove
the cover. Check
the filter to be sure
it is clean and in
good condition.
AIR DUCT
2. Reinstall the filter
and air cleaner
cover.
Cleaning
1. Tap the filter several times on a hard surface to remove dirt, or
blow compressed air [not exceeding 30 psi (207 kPa, 2.1 kg/cm²)]
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 and cover using a moist rag. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.

SPARK PLUG
Recommended Spark Plug: NGK BPR6ES
The recommended 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 to remove
the spark plug.
3. Inspect the spark plug. Replace it if damaged, badly fouled, if the
sealing washer is in poor condition, or if the electrode is worn.
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.028 – 0.031 in (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.
7. When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
8. 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.
9. Attach the spark plug cap to the spark plug.
