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.EBU23268Engine oil The engine oil level should be checked before
each ride. In addition, the oil must be changed at
the intervals specified 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:

8 9. 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.
10. Turn the engine off, wait at least ten minutes,
and then check the oil level and correct it if
necessary.
EBU27026Transmission 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.4. If no oil flows out, remove the transmission oil
filler bolt and its gasket.

then tighten the bolt to the specified torque.
6. Refill with the specified amount of the recom-
mended transmission oil. NOTICE: Make
sure that no foreign material enters the
transmission case.

7. Check the oil filler bolt gasket for damage, and
replace it if necessary.
8. Install the oil filler bolt and its gasket, and then
tighten the bolt to the specified torque.NOTICEECB01061Make sure that no oil gets on the tires or
wheels.9. Start the engine, and then let it idle for several
minutes while checking the transmission for
oil leakage. If oil is leaking, immediately turn
off the engine and check for the cause.
10. Turn the engine off, and then check the oil lev-
el and correct it if necessary.

82. 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.
