Do not dispose of a damaged or worn out
shock absorber assembly yourself. Take the
shock absorber assembly to a Yamaha deal-
er for any service.EBU30041Adjusting the rear shock absorber as-
sembly This shock absorber assembly is equipped with a
spring preload adjusting nut, a rebound damping
force adjusting screw, with a compression damp-
ing force adjusting bolt (for fast compression
damping), and a compression damping force ad-
justing screw (for slow compression damping).
WARNING
EWB02680Suspension components become hot during
operation. Never touch the compression
damping force adjusting bolt and screw, the re-
bound damping force adjusting screw or the
oil reservoir with your bare hand or skin until
the suspension components have cooled.
NOTICEECB00090Never turn an adjusting mechanism beyond
the minimum and maximum settings.TIPAlthough the total number of clicks or turns of a
damping force adjusting mechanism may not ex-
actly match the following specifications due to
small differences in production, the actual number
of clicks or turns always represents the entire ad-
justing range. To obtain a precise adjustment, it
would be advisable to check the number of clicks
or turns of each damping force adjusting mecha-
nism and to modify the specifications as neces-
sary.Spring preload
1. Loosen the locknut.
2. Turn the spring preload adjusting nut in direc-
tion (a) to increase the spring preload and
thereby harden the suspension, and in direc-
tion (b) to decrease the spring preload and
thereby soften the suspension.

PRE-OPERATION CHECKS
EBU19224Inspect 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
EWB00481Failure 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:
ITEM ROUTINE PAGE
FuelCheck fuel level in fuel tank, and add recommended fuel if neces-
sary.
Check fuel line for leakage. Correct if necessary.4-11, 5-4
Engine oilCheck oil level in engine, and add recommended oil to specified lev-
el if necessary.
Check ATV for oil leakage. Correct if necessary.5-4, 8-12
CoolantCheck coolant level in reservoir, and add recommended coolant to
specified level if necessary.
Check cooling system for leakage. Correct if necessary.5-4, 8-16

EBU19541Fuel Make sure that there is sufficient fuel in the tank.
(See page 4-11.)EBU19560Engine oil Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-12.)EBU19631Coolant Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-16.)TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.EBU19711Front and rear brakes Brake lever and brake pedalCheck that there is no free play in the brake le-
ver. If there is free play, have a Yamaha dealer
check the brake system.
Check for correct brake pedal height. (See page
8-32.) If the pedal height is incorrect, have a
Yamaha dealer adjust it.Check the operation of the lever and pedal. They
should move smoothly and there should be a
firm feeling when the brakes are applied. If not,
have a Yamaha dealer check the brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.
(See page 8-30.)
Brake fluid leakage
Check to see if any brake fluid is leaking out of the
pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If there is any leak-
age, have a Yamaha dealer check the brake sys-
tem.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance, check
the brake pads for wear. (See page 8-29.)Recommended brake fluid:

EBU26786Engine oil and oil filter element The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter element 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. Start the engine, warm it up until the engine oil
has reached a normal temperature of 60 °C
(140 °F), let it continue to idle for ten seconds
or more, and then turn the engine off.TIPTo achieve the proper engine oil temperature for
an accurate oil level reading, the engine must have
first completely cooled down, and then warmed up
again for several minutes to normal operating tem-
perature.3. Remove the engine oil tank filler cap, and then
wipe the engine oil dipstick off with a clean
rag.
4. Insert the dipstick in the filler hole (without
screwing it in), and then remove it again to
check the oil level.
TIPThe engine oil should be between the minimum
and maximum level marks.5. If the engine oil is at or below the minimum
level mark, add sufficient oil of the recom-
mended type through the engine oil tank filler
hole to raise it to the correct level. NOTICE:1. Engine oil tank

gradually fill the oil tank with the remaining oil
quantity while regularly checking the oil level
on the dipstick.
15. Install and tighten the engine oil tank filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down.NOTICEECB00300In 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 ofa 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.16. 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.
17. Turn the engine off, and then check the oil lev-
el and correct it if necessary.EBU23470Coolant The 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.EBU27941To check the coolant level
1. Place the ATV on a level surface. Recommended oil:
See page 10-1.
Oil quantity:
Without oil filter element replacement:
1.75 L (1.85 US qt, 1.54 Imp.qt)
With oil filter element replacement:
1.85 L (1.96 US qt, 1.63 Imp.qt)
