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

and add recommended fuel if neces-
sary.
• Check fuel line for leakage. Correct if necessary. 5-20, 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, 9-20
Final gear oil • Check ATV for oil leakage. Correct if necessary. 6-3, 9-25
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

EBU23072TIPSome maintenance items need more frequent service if you are riding in unusually wet, dusty, sandy or
muddy areas, or at full-throttle.21 Final gear oil • Change.
• Check ATV for oil leakage, and correct if neces-
sary. √√
22 Cooling system • Check coolant level and ATV for coolant leakage,
and correct if necessary. √√√√√
• Replace coolant. Every 2 years
23 *Moving parts and
cables •Lubricate.
√√√√
24 *Throttle lever • Check operation.
• Check throttle lever free play, and adjust if neces-
sary.
• Lubricate cable and lever housing. √√√√√
25 *Front and rear
brake switches • Check operation and correct if necessary.
√√√√√
26 *Lights and switches • Check operation and correct if necessary.
• Adjust headlight beams. √√√√√

93. If the coolant is at or below the minimum level
mark, remove panels A and C to access the
coolant reservoir. (See page 9-10.)
4. Remove the coolant reservoir cap, add cool- ant or distilled water to the maximum level
mark, install the reservoir cap, and then install
the panels. NOTICE: If coolant is not avail-
able, use distilled water or soft tap water
instead. Do not use hard water or salt wa-
ter since they are harmful to the engine. If
water has been used instead of coolant,
replace it with coolant as soon as possible,
otherwise the cooling system will not be
protected against frost and corrosion. If
water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible,
otherwise the effectiveness of the coolant
will be reduced.
[ECB01012]
TIP The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.
 If the engine overheats, see page 9-65 for fur-
ther instructions. 1. Coolant reservoir capCoolant reservoir capacity (up to the maxi-
mum level mark):

6. Place a container under the coolant reservoir
to collect the used coolant.
7. Remove the coolant reservoir cap.
8. Disconnect the coolant reservoir hose on the coolant reservoir side, and then drain the
coolant from the coolant reservoir.
9. After draining the coolant, thoroughly flush the cooling system with clean tap water.
10. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque. 11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the radi-
ator until it is full.
13. Pour the recommended coolant into the res- ervoir to the maximum level mark, and then
install the reservoir cap.
14. Loosen the water pump air bleed bolt, with- out removing it, to allow all of the air to es-
cape from the air bleed bolt hole.

915. When coolant begins to flow out of the bolt
hole, tighten the water pump air bleed bolt to
the specified torque.
16. Remove panel E. (See page 9-10.)
17. Loosen the clamp screw, and then remove the V-belt cooling duct. 18. Loosen the cylinder head air bleed bolt, with-
out removing it, to allow all of the air to es-
cape from the air bleed bolt hole.
19. When coolant begins to flow out of the bolt hole, tighten the cylinder head air bleed bolt
to the specified torque.
20. Start the engine and let it idle for ten minutes.
21. Rev the engine five times.

22. Pour additional coolant into the radiator until
it is full.
23. Stop the engine and allow it to cool. If the coolant level has dropped after the engine
has cooled, add sufficient coolant until it
reaches the top of the radiator, and then in-
stall the radiator cap.
24. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the V-belt cooling duct, and then tight-en the clamp screw.
26. Install the footboard by installing the bolts and nuts, and then tighten them to the speci-
fied torques.
TIPTighten footboard bolts B in the order shown. 1. Footboard nut
2. Footboard bolt A

9Engine overheating
WARNING
EWB02291Wait for the engine and radiator to cool before removing the radiator cap. You could be burned by
hot fluid and steam blown out under pressure. Always put a thick rag over the cap when opening.
Allow any remaining pressure to escape before completely removing the cap. TIP
Tap water can be used in an emergency. Change to the recommended coolant as soon as possible.
 The engine will tend to overheat if the radiator is caked with mud, or if the ATV is overloaded. Wait until the
engine has cooled.
Check the coolant level in the
reservoir and radiator.
The coolant level
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer check
and repair the cooling system.Add coolant. (See TIP.)
Start the engine. If the engine overheats again, have a
Yamaha dealer check and repair the cooling system.
There is
leakage.
There is
no leakage.
