Engine oil
Check the engine oil level each time before
starting the unit and after each 5 hours of
operation.
To check the engine oil level:
1. Move the unit onto a level surface.
2. Remove the oil dipstick (A, Fig. 5-1).
3. Wipe the oil from the dipstick with a
clean cloth.
4. Screw the dipstick back into the
engine.
5. Remove the oil dipstick (A , Fig. 5-1)
again.
6. The oil level should be between the
“FULL” and the “ADD” marks on the
dipstick. Refer to the engine owner
manual for proper oil specifications.
To change the engine oil:
1. Start the engine and allow it to warm
up to normal operating temperature.
2. Stop the engine and wait for all
moving parts to stop. Disconnect the
spark plug wire from the spark plug.
3. Move the unit onto a level surface.
4. Remove the engine oil dipstick (A, Fig.
5-1) to allow venting for the engine
crankcase.
5. Place a container with a minimum
capacity of two quarts below the oil
drain opening.
6. Fold a piece of cardboard or aluminum
foil into a shallow “V”, and position it
so the oil will drain through it into the
container.
7. Remove the oil drain plug (B, Fig. 5-1)
and allow the oil to drain into the
container.
8. When all oil has completely drained
from the crankcase securely replace
the oil drain plug (B).
9. Refer to the engine owner manual for
correct oil specifications. Fill the
engine through the oil dipstick opening
with the correct type and amount of oil
as indicated in the engine owner
manual.
10. Securely replace the oil dipstick (A).
NEVER DISPOSE OF WASTE OIL ON THE
GROUND, DOWN A DRAIN OR INTO A
LAKE, POND OR STREAM. CONTACT
LOCAL ENVIRONMENTAL AUTHORITIES
FOR PROPER OIL DISPOSAL
INSTRUCTIONS.
Ignition system
The engine has an electronic ignition
system which does not use points or a
condenser. The spark plug is the only
item requiring maintenance in this system.
Spark Plug
Annually or every 100 hours of operation,
remove and inspect the spark plug.
Replace the spark plug if the electrode is
pitted or burned or if the porcelain is
cracked. Refer to the engine owner
manual for correct spark plug specifica-
tions (Fig, 5-2).
Note: Use of an incorrect plug can
damage the engine.
Carburetor
The carburetor has been adjusted at the
factory and should not require additional
adjustment. If a black exhaust is noticed,
inspect the air cleaner first. An over-rich
mixture is usually caused by a clogged air
cleaner element, not an improperly
adjusted carburetor. Refer to the engine
owner manual or contact your dealer for
additional carburetor information.
