Throttle 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.
1. 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 le-
ver is released.
WARNING
POTENTIAL HAZARD
Malfunction of throttle.
WHAT CAN HAPPEN
The throttle could be hard to operate,
making it difficult to speed up or slow
down when you need to. This could
cause an accident.
HOW TO AVOID THE HAZARD
Check the operation of the throttle lever
before you start the engine. If it does not
work smoothly, check for the cause.
Correct the problem before riding the
ATV. Consult a Yamaha dealer if you
cant find or solve the problem yourself.
