PRE-OPERATION CHECKS
EBU19226Inspect 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. 4-17, 5-3
Engine oil • Check oil level in engine, and add recommended oil to specified
level if necessary.
• Check ATV for oil leakage. Correct if necessary. 5-3, 8-20
Final gear oil • Check ATV for oil leakage. Correct if necessary. 5-3, 8-24
Differential gear oil • Check ATV for oil leakage. Correct if necessary. 5-3, 8-27
Coolant • Check coolant level in reservoir, and add recommended coolant to
specified level if necessary.
• Check cooling system for leakage. Correct if necessary. 5-3, 8-29

EBU19542FuelMake sure that there is sufficient fuel in the tank.
(See page 4-17.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 8-20.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-24.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-27.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-29.)
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 8-45.)
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 8-43.)

86. Check the oil level check bolt gasket and the
oil filler bolt gasket for damage, and replace
them if necessary.
7. Install the oil level check bolt, the oil filler bolt and their gasket, and then tighten the bolts to
the specified torques.
8. Check the final gear case for oil leakage. If oil is leaking, check for the cause.
EBU23427Differential gear oilThe differential gear case must be checked for oil
leakage before each ride. If any leakage is found,
have a Yamaha dealer check and repair the ATV.
In addition, the differential gear oil level must be
checked and the oil changed as follows at the in-
tervals specified in the periodic maintenance and
lubrication chart. To check the differential gear oil level
1. Place the ATV on a level surface.
2. Remove the differential gear oil filler bolt and its gasket, and then check the oil level in the
differential 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 gasket for damage, and replace it if necessary.
Tightening torques:
Final gear oil level check bolt:10 N·m (1.0 kgf·m, 7.4 lb·ft)
Final gear oil filler bolt: 23 N·m (2.3 kgf·m, 17 lb·ft)

5. Install the oil filler bolt and its gasket, and then
tighten the bolt to the specified torque.
To change the differential gear oil 1. Place the ATV on a level surface.
2. Place an oil pan under the differential gear case to collect the used oil.
3. Remove the differential gear oil filler bolt, the differential gear oil drain bolt and their gasket
to drain the oil from the differential gear case. 4. Install the drain bolt and its new gasket, and
then tighten the bolt to the specified torque.
5. Refill with the recommended differential gear oil to the brim of the filler hole as shown.
NOTICE: Be sure no foreign material en-
ters the differential gear case.

EBU23471CoolantThe coolant level should be checked before each
ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.EBU34201To check the coolant level1. Park the ATV on a level surface.
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. 2. Check the coolant level in the coolant reser- voir.TIPThe coolant should be between the minimum and
maximum level marks.
