EBU18101Start switch“”
Push this switch to crank the engine with the start-
er. See the starting instructions on page 6-1 prior
to starting the engine.EBU18152Light switch“//OFF”
Set this switch to“” to turn on the low beams
and the taillight. Set the switch to“” to turn on
the high beams and the taillight. Set the switch to
“OFF” to turn off all the lights.NOTICEECB00041Do not use the headlights with the engine
turned off for an extended period of time, oth-
erwise the battery may discharge to the point
that the starter motor will not operate properly.
If this should happen, remove the battery and
recharge it. See page 8-39 for battery charging
information.EBU18170Horn switch“”
Press the switch to sound the horn.
EBU18282Throttle lever Once the engine is running, pushing the throttle le-
ver will increase the engine speed.
Regulate the speed of the ATV by varying the
throttle position. Because the throttle is spring-
loaded, the ATV will decelerate, and the engine will
return to an idle any time the throttle lever is re-
leased.
Before starting the engine, check the throttle to be
sure it is operating smoothly. Make sure it returns
to the idle position as soon as the lever is released.1. Throttle lever

EBU23213Checking the spark plug The spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the spark
plug should be removed and checked in accor-
dance with the periodic maintenance and lubrica-
tion chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
To remove the spark plug
1. Remove the spark plug cap.2. Remove the spark plug as shown, with the
spark plug wrench included in the owner’s tool
kit.
To check the spark plug
1. Check that the porcelain insulator around the
center electrode of the spark plug is a medi-
um-to-light tan (the ideal color when the ATV
is ridden normally).1. Spark plug cap

88. Check the sponge material and replace it if
damaged.
9. Tap the air filter element lightly to remove
most of the dust and dirt. Blow out the remain-
ing dirt with compressed air as shown. If the
air filter element is damaged, replace it.10. Pull the sponge material over the air filter ele-
ment.
11. Insert the air filter element assembly into the
air filter case, and then install the air filter case
cover by hooking the holders. NOTICE: Make
sure that the air filter element is properly
seated in the air filter case. Never operate
the engine with the air filter element re-
moved. This will allow unfiltered air to en-
ter the engine, causing rapid engine wear
and possible engine damage. Additionally,
operation without the air filter element will
affect carburetor jetting with subsequent
poor performance and possible engine
overheating.

TIPThe air filter element should be cleaned every 20–
40 hours. It should be cleaned more often if the
ATV is operated in extremely dusty areas. Each
time the air filter element maintenance is per-
formed, check the air inlet of the air filter case for
obstructions. Check the air filter case rubber joint
to the carburetor fittings and the rubber joint mani-
fold fittings for an air-tight seal. Tighten all fittings
securely to avoid the possibility of unfiltered air en-
tering the engine.EBU27082Cleaning the spark arrester Be sure the exhaust pipe and muffler are cool be-
fore cleaning the spark arrester.
1. Remove the tailpipe bolts.2. Remove the tailpipe by pulling it out of the
muffler.
3. Tap the tailpipe lightly, and then use a wire
brush to remove any carbon deposits from the
spark arrester portion of the tailpipe and inside
of the tailpipe housing.
