EBU38000FuelMake sure there is sufficient gasoline in the tank
before starting off. Refuel if necessary. (See page
5-17.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 9-19.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 9-24.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
9-27.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 9-29.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. EBU28533Front 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 9-42.)
 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 9-40.)

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 friction plates for wear.
(See page 9-40.)
EBU19762Throttle leverCheck the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.EBU38663TiresCheck and adjust the tire pressure before each
ride. Check tires for wear and damage. Tire pressure
A low-pressure tire gauge is included as standard
equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt
in the gauge could cause the first reading to be in-
correct.
Tire pressure must be checked and set when the
tires are cold. The tire pressure should be the
same on both sides, and must be adjusted ac-
cording to vehicle loading conditions. Set the tire
pressure as specified below.
WARNING! Opera-
tion of this vehicle with improper tire pressure
may cause severe injury or death from loss of
1. Low-pressure tire gauge
2. Tire air valve

EBU36894Periodic maintenance chart: General maintenance and lubricationTIPFor ATVs not equipped with an odometer or an hour meter, follow the month maintenance intervals in-
stead.
 For odometer or hour meter-equipped vehicles, follow the month maintenance interval if the ATV isn’t
ridden for the stated distance or engine operating hours.
 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

muddy areas, or at full-throttle.
 Hydraulic brake service
• Regularly check and, if necessary, correct the brake fluid level.
• Every two years replace the internal components of the brake master cylinder and calipers, and
change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged. UBHT60E0.book Page 9 Wednesday, August 4, 2021 8:09 AM
