PRE-OPERATION CHECKS
EBU19227Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always
follow the inspection and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWB00482Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equip-
ment damage. Do not operate the vehicle if you find any problem. If a problem cannot be corrected
by the procedures provided in this manual, have the vehicle inspected by a Yamaha dealer. Before using this vehicle, check the following points:
ITEMROUTINE PAGE
Fuel • Check fuel level in fuel tank,
and add recommended fuel if neces-
sary.
• Check fuel line for leakage. Correct if necessary. 5-17, 6-3
Engine oil • Check oil level in engine, and add recommended oil to specified
level if necessary.
• Check ATV for oil leakage. Correct if necessary. 6-3, 9-19
Final gear oil • Check ATV for oil leakage. Correct if necessary. 6-3, 9-24
Differential gear oil • Check ATV for oil leakage. Correct if necessary. 6-3, 9-27
Coolant • Check coolant level in reservoir, and add recommended coolant to
specified level if necessary.
• Check cooling system for leakage. Correct if necessary. 6-3, 9-29

EBU38000FuelMake sure there is sufficient gasoline in the tank
before starting off. Refuel if necessary. (See page
5-17.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 9-19.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 9-24.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
9-27.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 9-29.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. EBU28533Front and rear brakesBrake levers and brake pedal
Check that there is no free play in the front
brake lever. If there is free play, have a Yamaha
dealer check the brake system.
 Check for correct free play in the rear brake le-
ver and brake pedal. If the free play is incorrect,
adjust it. (See page 9-42.)
 Check operation of the levers and pedal. They
should move smoothly and there should be a
firm feeling when the brake is applied. If not,
have a Yamaha dealer check them.
Brake fluid level (front brake)
Check the brake fluid level. Add fluid if necessary.
(See page 9-40.)

TIPIf a torque wrench is not available when installing
the 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 speci-
fied torque as soon as possible. 3. Install the spark plug cap.EBU30245Engine oil and oil filter cartridgeThe 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
specified in the periodic maintenance chart.
To check the engine oil level1. Park the ATV on a level surface.
2. Remove panel E. (See page 9-10.)
3. Check the engine oil level on a cold engine.
TIPIf the engine was started before checking the oil
level, warm up the engine, and then wait at least
ten minutes until the oil settles for an accurate
reading. 4. Remove the engine oil filler cap, and then wipe the dipstick with a clean rag.
5. Insert the dipstick into the filler hole (without screwing it in), and then remove it again to
check the oil level.
Tightening torque:
Spark plug:18 N

TIPThe engine oil should be between the tip of the
dipstick and the maximum level mark. 6. If the engine oil is not between the tip of thedipstick and the maximum level mark, add
sufficient oil of the recommended type to
raise it to the correct level. NOTICE: Be sure
the engine oil is at the correct level, other-
wise engine damage may result.
[ECB00852]
7. Check the filler cap O-ring for damage, and replace it if necessary.
8. Install the engine oil filler cap and the panel.
To change the engine oil (and replace the oil fil-
ter cartridge) 1. Park the ATV on a level surface.
2. Remove panel E. (See page 9-10.)
3. Start the engine, warm it up for several min- utes, and then turn it off.
4. Place an oil pan under the engine to collect the used oil.
5. Remove the engine oil filler cap, and then re- move the engine oil drain bolt and its gasket
to drain the oil from the crankcase.

12. Refill with the specified amount of the recom-
mended engine oil.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher.
 Make sure that no foreign material enters the
crankcase.
13. Check the engine oil filler cap O-ring for dam-
age, and then install the filler cap.
14. Start the engine and let it idle for several min- utes while checking for oil leakage. If any oil
leakage is found, immediately turn the engine
off and check for the cause.
15. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.
16. Install panel E.EBU38620Why YamalubeYAMALUBE oil is a Genuine YAMAHA Part born of the engineers’ passion and belief that engine oil is
an important liquid engine component. We form
teams of specialists in the fields of mechanical en-
gineering, chemistry, electronics and track test-
ing, and have them develop the engine together
with the oil it will use. Yamalube oils take full ad-
vantage of the base oil’s qualities and blend in the
ideal balance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and synthetic oils have their own distinct characters and value.
Yamaha’s experience gained over many years of

1960’s helps make Yamalube the best choice for
your Yamaha engine.
EBU28569Final gear oilThe 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 speci-
fied in the periodic maintenance chart.
To check the final gear oil level
1. Park the ATV on a level surface.
2. Remove the final gear oil filler bolt and its gas- ket, and then check the oil level in the final
gear case. The oil level should be at the brim
of the filler hole. 3. If the oil is below the brim of the filler hole, add
sufficient oil of the recommended type to
raise it to the correct level.
4. Check the oil filler bolt gasket for damage, and replace it if necessary.
5. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
