EBU00063Throttle lever
Once the engine is running, movement of the
throttle lever will increase the engine speed.
Regulate the speed of the machine by varying
the throttle position. Because the throttle is
spring-loaded, the machine will decelerate, and
the engine will return to an idle any time the
hand is removed from the throttle lever.
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.wMalfunction of the throttle could make it diffi-
cult to speed up or slow down when you
need to. This could cause an accident.
Check the operation of the throttle lever
before you start the engine. If the throttle
does not work smoothly, check for the
cause. Correct the problem before riding the
ATV or consult a Yamaha dealer.

EBU00180Starting a warm engine
To start a warm engine, refer to the “Starting a
cold engine” section. The starter (choke) should
not be used. The throttle should be opened
slightly.EBU00182Warming up
To get maximum engine life, always warm up
the engine before starting off. Never accelerate
hard with a cold engine! To see whether or not
the engine is warm, check if it responds to the
throttle normally with the starter (choke) turned
off.

3. Remove the dipstick and wipe it off with a
clean rag. Insert the dipstick in the filler hole
without screwing it in.NOTE:Wait a few minutes until the oil level settles
before checking.4. Remove the dipstick and inspect the oil level.
5. The oil level should be between the maximum
and minimum marks. If the level is low, add oil
to raise it to the proper level.
