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

NOTICE: For maximum engine life, never
accelerate hard when the engine is cold!
[ECB00162]
TIP
If the engine fails to start, release the start
switch, then push it again. Pause a few seconds
before the next attempt. Each cranking shouldbe as short as possible to preserve battery ener-
gy. Do not crank the engine more than 10 sec-
onds on each attempt.

If the battery is discharged, pull the recoil starter
to start the engine.7. If the engine is started with the starter (choke)
in position (1), the starter (choke) should be
returned to position (2) to warm up the engine.
If the engine is started with the starter (choke)
in position (2), keep the starter (choke) in this
position to warm up the engine.
8. Continue warming up the engine until it idles
smoothly, then return the starter (choke) to
position (3) before riding.TIPThe engine is warm when it responds quickly to the
throttle with the starter (choke) turned off.EBU20291Starting a warm engine Follow the same procedure as for starting a cold
engine, with the exception that the starter (choke)
is not required when the engine is warm. Instead,
start the engine with the throttle slightly open.
1. Fully open
2. Half open
3. Closed

Replace the brake hoses every four years and if cracked or damaged.23*BatteryCheck electrolyte level and specific gravity, and
correct if necessary.
