WARNING

EWB00480
Always inspect your ATV each time you use it to make sure it is in safe operating condition.
Always follow the inspection and maintenance procedures and schedules described in the Owner’s
Manual. Failure to inspect increases the possibility of an accident or equipment damage.
NOTE:

The maintenance of some items in the table has to be performed by a Yamaha dealer. Refer to the periodic
maintenance charts on page 8-3 to determine which service should be performed by a Yamaha dealer.

EBU19550
Fuel and 2-stroke engine oil mixing
ratio
If Yamalube “R” oil is not available, select an oil
from the following list.
CAUTION:

ECB00140
Never mix two types of 2-stroke engine oil in
the same batch. Always use the same type of
oil to ensure maximum engine performance.
EBU19580
Transmission oil
Make sure that the transmission oil is at the speci-
fied level. Add oil as necessary. (See page 8-10.)
EBU19630
Coolant
Make sure that the coolant is at the specified level.
Add coolant as necessary. (See page 8-12.)
NOTE:

The coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture.WARNING

EWB00510
Wait 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.
EBU19710
Front and rear brakes
Brake lever and brake pedal

Check 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 Recommended 2-stroke engine oil:

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.
EBU23341
Transmission oil
The transmission oil level should be checked be-
fore each ride. In addition, the transmission oil
must be changed at the intervals specified in the
periodic maintenance and lubrication chart.
To check the transmission oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Wait a few minutes until the oil settles, remove
the oil filler cap, wipe the dipstick off with a
clean rag, insert it back into the oil filler hole
(without screwing it in), and then remove it
again to check the oil level.NOTE:

The transmission oil should be between the mini-
mum and maximum level marks.
4. If the oil is at or below the minimum level mark,
add sufficient oil of the recommended type to
raise it to the correct level.
5. Insert the dipstick into the oil filler hole, and
then tighten the oil filler cap.

2. Start the engine, warm it up for several min-
utes, and then turn it off.
3. Place an oil pan under the transmission to col-
lect the used oil.
4. Remove the oil filler cap and the drain bolt to
drain the oil from the transmission.
5. Install the drain bolt, and then tighten it to the
specified torque.6. Add the specified amount of the recommend-
ed transmission oil, and then install and tight-
en the oil filler cap.CAUTION:
ECB00430

In order to prevent clutch slippage (since the
transmission 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 ad-
dition, do not use oils labeled “ENERGY
CONSERVING II” or higher.

Make sure that no foreign material enters the
crankcase.
7. Start the engine, and then let it idle for several
minutes while checking the transmission for
oil leakage. If oil is leaking, immediately turn
the engine off and check for the cause.
8. Turn the engine off, and then check the oil lev-
el and correct it if necessary.

Rear brake

Observe these precautions:

When checking the fluid level, make sure that
the top of the brake fluid reservoir is level.

Use only the recommended quality brake fluid,
otherwise the rubber seals may deteriorate,
causing leakage and poor braking performance.

Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.

Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and may
result in vapor lock.

Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid imme-
diately.

As the brake pads wear, it is normal for the brake
fluid level to gradually go down. However, if the
brake fluid level goes down suddenly, have a
Yamaha dealer check the cause.
EBU24290
Changing the brake fluid
Have a Yamaha dealer change the brake fluid at
the intervals specified in the NOTE after the peri-
odic maintenance and lubrication chart. In addi-
tion, have the oil seals of the master cylinders and
calipers as well as the brake hoses replaced at the
intervals listed below or whenever they are dam-
aged or leaking.

Oil seals: Replace every two years.

Brake hoses: Replace every four years.

CAUTION:

ECB00560
The drive chain must be lubricated after wash-
ing the ATV or riding in the rain.
1. Clean the drive chain with kerosene and a
small soft brush.
CAUTION:

ECB00570
To prevent damaging the O-rings, do not clean
the drive chain with steam cleaners, high-pres-
sure washers or inappropriate solvents.
2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a
special O-ring chain lubricant.
CAUTION:

ECB00580
Do not use engine oil or any other lubricants
for the drive chain, as they may contain sub-
stances that could damage the O-rings.
EBU24900
Checking and lubricating the cables
The operation and the condition of all control ca-
bles should be checked before each ride, and the
cables and cable ends should be lubricated if nec-
essary. If a cable is damaged or does not move
smoothly, have a Yamaha dealer check or replace
it.
WARNING

EWB02130
Inspect cables frequently and replace if dam-
aged. Corrosion can result when the cable
sheaths become damaged, and cables can
also become frayed or kinked, which could re-
strict the operation of controls and lead to an
accident or injury.
