el. Add oil as necessary. (See page 8-22.)EBU19590Final gear oil Make sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-26.)EBU19600Differential gear oil Make sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-28.)EBU19631Coolant Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-30.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.EBU29081Front and rear brakes Brake levers and brake pedal
Check that there is no free play in the front and
rear brake levers. If there is free play, have a
Yamaha dealer check the brake system.
Check for correct free play in the brake pedal. If
the free play is incorrect, adjust it. (See page
8-47.)
Check the operation of the brake levers and
pedal. They should move smoothly and there
should be a firm feeling when the brakes are ap-
plied. If not, have a Yamaha dealer check the
brake system.

TIPIf 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 as
soon as possible.4. Install the spark plug cap.EBU27463Engine 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.TIPIf 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 settles
for an accurate reading.
3. Remove panel F. (See page 8-8.)
4. Remove the engine oil dipstick, and then wipe
it off with a clean rag.

TIPThe engine oil should be between the minimum
and 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.
NOTICE: Be sure the engine oil is at the
correct level, otherwise engine damage
may result.

7. Insert the dipstick completely into the oil filler
hole.
8. Install the panel.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.
TIPSkip steps 5–9 if the oil filter cartridge is not being
replaced.5. Remove panel G. (See page 8-8.)

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.TIPThe final gear oil level must be checked when the
engine is cold.
2. Remove the final gear oil level check bolt, and
then check the oil level in the final gear case.
The oil level should be at the brim of the check
hole.
3. If the oil is below the brim of the check hole,
