ENGINE OIL Recommended Oil Use 4-stroke motor oil that meets
or exceeds the requirements for
API service category SJ or later
(or equivalent). Always check the
API service label on the oil
container to be sure it includes
the letters SJ or later (or
equivalent).
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 1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but
do not screw it in, then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark on the dipstick,
fill with the recommended oil to the upper limit mark (bottom edge
of the oil fill hole). Do not overfill.
5. Reinstall the oil filler cap/dipstick.
Oil Change Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Place a suitable container
next to the engine to catch
the used oil.
2. Remove the oil filler cap/
dipstick, the oil drain plug
and washer.
3. Allow the used oil to drain
completely, then reinstall
the drain plug and new
washer. Tighten the drain
plug securely.
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 or pour it on the ground or down a drain.
4. With the engine in a level position, fill to the upper limit mark
(bottom edge of the oil fill hole) on the dipstick with the
recommended oil (see page 6) Do not overfill.
NOTICE
Running the engine with a low oil level can cause engine damage.
This type of damage is not covered by the DISTRIBUTOR’S
LIMITED WARRANTY.
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 an air filter, or with a damaged filter, will
allow dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered under the DISTRIBUTOR’S LIMITED
WARRANTY (see page 11).
Inspection 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.
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.
