WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow extra time and distance
for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _

4-27
WARNING
_ Always stop the ATV before changing from
2WD to 4WD, or from 4WD to 4WD-LOCK, or
vice-versa.
The ATV handles differently in 2WD than in
4WD and in 4WD-LOCK in some circumstanc-
es. Changing from 2WD to 4WD, or from 4WD
to 4WD-LOCK, or vice-versa while moving may
cause the ATV to unexpectedly handle differ-
ently. This could distract the operator and in-
crease the risk of losing control and an
accident. _

Differential gear lock switch “LOCK”/“4WD”
To lock the differential gear in 4WD, make sure the
on-command four-wheel-drive switch is set to
“4WD”, stop the ATV, move the lever to position
b, and then set the switch to “LOCK”. When the
differential gear is locked, the differential gear lock
indicator (“DIFF.LOCK”) light will come on along
with the indicator “” in the speedometer unit
display.
To release the differential gear lock, stop the ATV
and set the switch to “4WD”.
WARNING
_ Always ride at a slow speed when the ATV is in
4WD-LOCK, and allow extra time and distance
for maneuvers.
All wheels turn at the same speed when the dif-
ferential is locked, so it takes more effort to
turn the ATV. The amount of effort is more the
faster you go. You may lose control and have
an accident if you cannot make a sharp
enough turn for the speed you are traveling. _

EBU00063
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 en-
gine will return to an idle any time the hand is re-
moved 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.
WARNING
Malfunction 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.

Speed limiter
The speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum. Turning in the adjusting screw limits
the maximum engine power available and de-
creases the maximum speed of the ATV.
WARNING
_ Improper adjustment of the speed limiter and
throttle could cause throttle cable damage or
improper throttle operation. You could lose
control, have an accident or be injured. Do not
turn the adjusting screw out more than 12 mm
or the throttle cable could be damaged. Always
make sure the throttle lever free play is adjust-
ed to 3–5 mm. See page 8-87. _
