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 8-11.)EBU19590Final gear oil Make sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 8-15.)EBU19600Differential gear oil Make sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
8-18.)EBU27672Front and rear brakes Brake 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 lever
and brake pedal. If the free play is incorrect, ad-
just it. (See page 8-30.)●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 8-29.)
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. Specified brake fluid:

vals. However, keep in mind that if the ATV isn’t used for a long period of time, the month maintenance
intervals should be followed.●Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools,

EBU29841Checking the brake fluid level Before 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
EWB02720Improper 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 fluid and may result in vapor lock.NOTICEECB01160Brake 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 leak-
age. If the brake fluid level goes down suddenly,
have a Yamaha dealer check the cause before fur-
ther riding.
EBU24282Changing the brake fluid Have 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 be-
low or whenever they are damaged or leaking.●Oil seals: Replace every two years.●Brake hoses: Replace every four years.EBU24394Checking the front brake lever free play The 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.
EBU30690Adjusting the brake pedal height, and
the brake pedal and rear brake lever
free play The 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
