EBU19541 
Fuel  
Make sure that there is sufficient fuel in the tank.
(See page 4-6.) 
EBU19560 
Engine oil  
Make sure that the engine oil is at the specified lev-
el. Add oil as necessary. (See page 8-9.) 
EBU19580 
Transmission oil  
Make sure that the transmission oil is at the speci-
fied level. Add oil as necessary. (See page 8-12.) 
EBU19651 
Front and rear brakes  
Brake levers 
 
Check for correct free play in the brake levers. If
the free play is incorrect, adjust it. (See pages
8-27 and 8-32.) 
 
Check operation of the levers. They should
move smoothly and there should be a firm feel-
ing when the brake is applied. If not, have the
ATV 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 brakes for wear. (See page 8-26.) 
EBU19761 
Throttle lever  
Check 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. 
EBU19770 
Drive chain  
Check the condition of the drive chain and check
the drive chain slack. Lubricate and adjust the
drive chain as necessary. (See page 8-33.) 
EBU19794 
Tires  
Check tire pressure regularly to make sure it is at
the recommended specifications. Also check for
wear and damage. 
Tire pressure 
Use the low-pressure tire gauge to check and
adjust tire pressures when the tires are cold.

8. Refill with the specified amount of the recom-
mended engine oil, and then install and tight-
en the engine oil filler cap.
TIP
 
Be sure to wipe off spilled oil on any parts after the 
engine and exhaust system have cooled down.
NOTICE
 
ECB00330  
 
Do not use oils with a diesel specification of
“CD” or oils of a higher quality than speci-
fied. In addition, do not use oils labeled “EN-
ERGY CONSERVING II” or higher. 
 
Make sure that no foreign material enters the 
crankcase. 
9. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oilis leaking, immediately turn the engine off and
check for the cause.
10. Turn the engine off, wait at least ten minutes,
and then check the oil level and correct it if
necessary. 
EBU27026 
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, and
then loosen the transmission oil check screw
located at the right side of the crankcase until
oil flows out. Tightening torque:
Engine oil drain bolt:
32 Nm (3.2 m·kgf, 23 ft·lbf)
Recommended oil:
See page 10-1.
Oil quantity:

4. If no oil flows out, remove the transmission oil
filler bolt and its gasket.5. Pour the recommended type of oil in the trans-
mission oil filler hole until it flows out of the
check screw hole.
6. Tighten the oil check screw to the specified
torque.
7. Check the oil filler bolt gasket for damage, and
replace it if necessary.

specified intervals in the periodic maintenance
chart.

TIP
 
There is a check hose at the bottom of the air filter
case. If dust or water collects in this hose, empty
the hose and clean the air filter element and air fil- 
ter case. Recommended transmission oil:
See page 10-1.

2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive chain with a
special O-ring chain lubricant.  
NOTICE: 
 Do
not use engine oil or any other lubricants
for the drive chain, as they may contain
substances that could damage the O-
rings. 
[ECB00581] 
  
EBU24901 
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
 
EWB02581  
 
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
restrict the operation of controls and lead to
an accident or injury. 
 
Always make sure all control cables work
smoothly before you begin riding in cold
weather. If the control cables are frozen or do
not work smoothly, you could be unable to
control the ATV, which could lead to an acci- 
dent or collision.
