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. 4-8, 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, 8-11
Final gear oil • Check ATV for oil leakage. Correct if necessary. 5-3, 8-15
Front brake • Check operation. If soft or spongy, have Yamaha dealer bleed hy-
draulic system.
• Check brake pads for wear, and replace if necessary.
• Check brake fluid level in reservoir, and add specified brake fluid to specified level if necessary.
• Check hydraulic system for leakage. Correct if necessary. 5-3, 8-26, 8-27, 8-29

EBU19542FuelMake sure that there is sufficient fuel in the tank.
(See page 4-8.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 8-11.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-15.)EBU27673Front 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 8-29.) 
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 8-27.)
Brake fluid leakage (front brake)
Check to see if any brake fluid is leaking out of the
hose, joint or brake fluid reservoir of the front
brake. Apply the brake firmly for one minute. If the
lever moves slowly inward, there may be a leak in
the brake system. If there is any leakage, the brake
system should be checked by a Yamaha dealer.
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 and shoes for wear. (See
page 8-26.) Specified brake fluid:

EBU2186BGeneral maintenance and lubrication chartTIPFor ATVs not equipped with an odometer or an hour meter, follow the month maintenance intervals.
 For ATVs equipped with an odometer or an hour meter, follow the km (mi) or hours maintenance inter-
vals. However, keep in mind that if the ATV isn’t used for a long period of time, the month maintenance
intervals should still be followed.
 Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools,
data and technical skills. NO. ITEM CHECK OR MAINTENANCE

TIPThe wheels need to be removed to check the
brake pads. (See page 8-44.) EBU24181Rear brake shoes
The rear brake is provided with a wear indicator,
which allows you to check the brake shoe wear
without having to disassemble the brake. To
check the brake shoe wear, check the position of
the wear indicator while applying the brake. If abrake shoe has worn to the point that the wear in-
dicator reaches the wear limit line or mark, have a
Yamaha dealer replace the brake shoes as a set.
EBU29843Checking the brake fluid levelBefore riding, check that the brake fluid is above
the minimum level mark. Check the brake fluid lev-
el with the top of the reservoir level. Replenish the
brake fluid if necessary.

WARNING
EWB02721Improper maintenance can result in loss of
braking ability. Observe these precautions:
Insufficient brake fluid may allow air to enter
the brake system, reducing braking perfor-
mance.
 Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed contain-
er. 
Use only the specified brake fluid; otherwise,
the rubber seals may deteriorate, causing
leakage.
 Refill with the same type of brake fluid. Add-
ing a brake fluid other than DOT 4 may result
in a harmful chemical reaction.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Water will
significantly lower the boiling point of the flu-
id and may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately. As the brake pads wear, it is normal for the brake
fluid level to gradually go down. A low brake fluid
level may indicate worn brake pads and/or brake
system leakage; therefore, be sure to check the
brake pads for wear and the brake system for
leakage. If the brake fluid level goes down sud-
denly, have a Yamaha dealer check the cause be-
fore further riding.

EBU24283Changing the brake fluidHave a Yamaha dealer change the brake fluid at
the intervals specified in the periodic maintenance
and lubrication chart. In addition, have the oil seals
of the brake master cylinder and calipers as well
as the brake hoses replaced at the intervals listed
below or whenever they are damaged or leaking.
Oil seals: Replace every two years.
 Brake hoses: Replace every four years.EBU24395Checking the front brake lever free
playThe brake lever free play must be checked at the
intervals specified in the periodic maintenance
and lubrication chart. The brake lever should have
no free play as shown. If there is free play, have a
Yamaha dealer check the brake system.
EBU30691Adjusting the brake pedal height, and
the brake pedal and rear brake lever
free playThe brake pedal height, brake pedal free play, and
rear brake lever free play must be checked and, if
necessary, adjusted at the intervals specified in
the periodic maintenance and lubrication chart.TIP Always perform this maintenance completely in
the following order whenever adjusting the rear
brake.1. No brake lever free play
