4. Once immediate safety hazards are con-
firmed not to exist, you may remove your hel-
met to more closely inspect your vehicle.
Check for external signs of wear, broken
parts, fluid leaks, cracks in the frame, suspen-
sion damage, wheel damage, and so on. Fuel,
oil, and coolant usually give off a noticeable
odor.
5. If your vehicle will not restart or if it is unsafe to ride, then turn off all vehicle systems (en-
gine stop switch, main switch, and fuel cock),
and then signal or go for help.
Aftermarket Parts, Accessories, and Modifica-
tions
While you may find aftermarket products similar in
design and quality to genuine Yamaha accesso-
ries, recognize that some aftermarket accessories
or modifications are not suitable because of poten-
tial safety hazards to you or others. Installing after-
market products or having other modifications
performed to your vehicle that change any of the
vehicle’s design or operation characteristics can
put you and others at greater risk of serious injury
or death. You are responsible for injuries related to changes in the vehicle. Keep the following guide-
lines in mind, as well as those provided under
“Loading” when mounting accessories.
●Never install accessories that would impair the
performance of your ATV. Carefully inspect the
accessory before using it to make sure that it
does not in any way reduce ground clearance,
limit suspension travel, steering travel or control
operation.●Accessories fitted to the ATV can create instabil-
ity due to improper weight distribution.●Bulky or large accessories may seriously affect
the stability of the ATV.●Certain accessories can displace the operator
from his or her normal riding position. This im-
proper position limits the freedom of movement
of the operator and may limit control ability,
therefore, such accessories are not recom-
mended.●Use caution when adding electrical accessories.
If electrical accessories exceed the capacity of
the ATV’s electrical system, an electric failure
could result, which could cause a dangerous
loss of lights or engine power.

EBU30240Engine 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 level1. Place the ATV on a level surface.
2. Remove panel E. (See page 8-10.)
3. 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.4. Remove the engine oil filler cap, and then wipe the engine oil dipstick off with a clean
rag. 5. Insert the dipstick into the filler hole (without
screwing it in), and then remove it again to
check the oil level.
TIPThe engine oil should be between the tip of the dip-
stick and the maximum level mark.1. Engine oil filler cap
