NOTE:If a torque wrench is not available when installing
a spark plug, a good estimate of the correct torque
is 1/4–1/2 turn past finger tight. However, the spark
plug should be tightened to the specified torque assoon as possible.
4. Install the spark plug cap.EBU27461Engine oil and oil filter cartridge The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter cartridge replaced at the intervals spec-
ified in the periodic maintenance and lubrication
chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Check the engine oil level on a cold engine.NOTE:If the engine was started before checking the oil
level, be sure to warm up the engine sufficiently,
and then wait at least 10 minutes until the oil settlesfor an accurate reading.
3. Remove panel F. (See page 8-8.)4. Remove the dipstick, and then wipe it off with
a clean rag.
5. Insert the dipstick completely into the oil filler
hole, and then remove it again to check the oil
level.

NOTE:The engine oil should be between the minimumand maximum level marks.
6. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type to raise it to the correct level.
7. Insert the dipstick completely into the oil filler
hole.
8. Install the panel.
CAUTION:ECB00850Be sure the engine oil is at the correct level,otherwise engine damage may result.
To change the engine oil (with or without oil fil-
ter cartridge replacement)
1. Place the ATV on a level surface.
2. Remove panel F. (See page 8-8.)
3. Place an oil pan under the engine to collect
the used oil.
4. Remove the dipstick, and then remove the en-
gine oil drain bolt to drain the oil from the
crankcase.

Make sure that no foreign material enters thecrankcase.
12. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
13. Turn the engine off, wait at least ten minutes,
and then check the oil level and correct it if
necessary.
14. Install panel F.EBU27302Final gear oil The final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals specified
in the periodic maintenance and lubrication chart.
To check the final gear oil level
1. Place the ATV on a level surface.NOTE:The final gear oil level must be checked on a coldengine.2. Remove the final gear oil level check bolt, and
then check the oil level in the final gear case.
NOTE:The oil level should be at the brim of the checkhole.
3. If the oil is below the brim of the check hole,
remove the final gear oil filler bolt, and then
add sufficient oil of the recommended type to
raise it to the correct level.1. Final gear oil

oil level check bolt, and the final gear oil drain
bolt to drain the oil from the final gear case.
