ITEM ROUTINE PAGE
Fuel 
Check fuel level in fuel tank, and add recommended fuel if neces-
sary.
 Check fuel line for leakage. Correct if necessary. 4-10, 5-3
Engine oil 
Check oil level in engine, and add recommended oil to specified lev-
el 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

EBU19541Fuel Make sure that there is sufficient fuel in the tank.
(See page 4-10.)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:

TIPIf a torque wrench is not available when installing
the 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.3. Install the spark plug cap.EBU23319Engine oil and oil filter cartridge The engine oil level should be checked before
each ride. In addition, the oil must be changed and
the oil filter cartridge replaced at the intervals spec-
ified in the periodic maintenance and lubrication
chart.
To check the engine oil level 1. Place the ATV on a level surface.
2. Check the engine oil level on a cold engine.
TIPIf the engine was started before checking the oil
level, be sure to warm up the engine sufficiently,
and then wait at least ten minutes until the oil set-
tles for an accurate reading.3. Remove the engine oil filler cap, and then wipe the engine oil dipstick off with a clean
rag.
4. Insert the dipstick into the filler hole (without screwing it in), and then remove it again to
check the oil level.
Tightening torque:

TIPThe engine oil should be between the tip of the dip-
stick and the maximum level mark.5. If the engine oil is not between the tip of thedipstick and the maximum level mark, add
sufficient oil of the recommended type to raise
it to the correct level. NOTICE: Be sure the
engine oil is at the correct level, otherwise
engine damage may result.
[ECB00851]
6. Insert the dipstick into the oil filler hole, and then tighten the engine oil filler cap. To change the engine oil (with or without oil fil-
ter cartridge replacement)
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. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler cap, and then re- move the engine oil drain bolt and its gasket to
drain the oil from the crankcase.1. Engine oil dipstick

9. Refill with the specified amount of the recom-
mended engine oil, and then install and tight-
en the engine oil filler cap.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down.NOTICEECB00300
In order to prevent clutch slippage (since the
engine 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 addition,
do not use oils labeled “ENERGY CONSERV-
ING II ” or higher.

Make sure that no foreign material enters the
crankcase.10. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
11. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.EBU23386Final gear oil The final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals specified
in the periodic maintenance and lubrication chart.
To check the final gear oil level1. Place the ATV on a level surface.
2. Remove the final gear oil filler bolt and its gas- ket, and then check the oil level in the final
gear case. The oil level should be at the brim
of the filler hole.
Recommended oil:
See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.20 L (2.33 US qt, 1.94 Imp.qt)
With oil filter cartridge replacement: 2.30 L (2.43 US qt, 2.02 Imp.qt)

83. If the oil is below the brim of the filler hole, add
sufficient oil of the recommended type to raise
it to the correct level.
4. Check the gasket for damage, and replace it if necessary.
5. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque. To change the final gear oil
1. Place the ATV on a level surface.
2. Remove the final gear case guard by remov- ing the bolts.
3. Place an oil pan under the final gear case to collect the used oil.
4. Remove the final gear oil filler bolt, the final gear oil drain bolt, and their gasket to drain the
oil from the final gear case.
