EBU30466On-Command drive switch “4WD/LOCK”
(YFM70KPXJ / YFM70KPAJ / YFM70KPHJ /
YFM70KPSJ)
Stop the ATV and push this switch to change from
standard four-wheel drive to four-wheel drive with
the differential locked. Select the appropriate
switch position according to the terrain and the
conditions.
“4WD” (four-wheel drive): Power is supplied to
the front and rear wheels, with the front differen-
tial unlocked.
“LOCK” (four-wheel drive with the differential
gear locked): Power is supplied to the front and
rear wheels and the differential gear is locked.
Unlike in four-wheel drive, all wheels turn at the
same speed, giving maximum traction.
WARNING
EWB00132Always stop the ATV before changing from
four-wheel drive to four-wheel-drive differen-
tial gear lock or vice versa.
The ATV handles differently in four-wheel drive
than in differential gear lock in some circum-
stances. Changing from four-wheel drive to
differential gear lock or vice versa while mov-
ing may cause the ATV to handle differently un- expectedly. This could distract the operator
and increase the risk of losing control and
causing an accident.
To access the “4WD/LOCK” switch, set the
“2WD/4WD” switch to “4WD”, and then move the
drive switch lock lever to the right.TIP
When the switch is set to “LOCK” or “4WD”, the
differential gear lock icon and indicator light will
flash until the differential gear is completely
locked or unlocked.1. On-Command drive switch “4WD/LOCK”

When the icon and indicator light are flashing,
turning the handlebar back and forth will help
the differential gear lock to engage or disen-
gage.
Riding before the differential gear is properly en-
gaged or disengaged (e.g., when the icon and
indicator light are flashing) will cause the vehicle
speed to be limited until the differential gear is
completely engaged or disengaged.
When the ATV is in four-wheel-drive differential
gear lock, the maximum traveling speed is limit-
ed to 35 km/h (22 mi/h). However, if conditions
require full engine power to be available, push
and hold the override switch to disable the dif-
ferential gear lock speed limiter. (See page
4-10.)
WARNING
EWB00141Always ride at a slow speed when the ATV is in
differential gear lock, and allow extra time and
distance for maneuvers.
All wheels turn at the same speed when the dif-
ferential gear is locked, so it takes more effort
to turn the ATV. The effort needed to turn in-
creases with the riding speed. You may lose control and have an accident if you cannot
make a sharp enough turn for the speed you
are traveling.

“2WD” (two-wheel drive): Power is supplied to
the rear wheels only, giving a smooth ride and
fuel economy.
“4WD” (four-wheel drive): Power is supplied to
the front and rear wheels, giving increased trac-
tion.
WARNING
EWB00164Always stop the ATV before changing from
two-wheel drive to four-wheel drive and vice
versa. The ATV handles differently in two-
wheel drive than in four-wheel drive in some
circumstances. Changing from two-wheel
drive to four-wheel drive or vice versa while
moving may cause the ATV to unexpectedly
handle differently. This could distract the oper-
ator and increase the risk of losing control and
of causing an accident.
EBU18284Throttle leverPush the throttle lever to increase engine speed
and the speed of the ATV. Because the throttle is
spring-loaded, the ATV will decelerate and the en-
gine will return to an idle any time the throttle lever
is released.TIPBefore 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

EBU18325Speed limiterThe speed limiter keeps the throttle from fully
opening, even when the throttle lever is pushed to
the maximum.
Adjusting the speed limiter1. Loosen the locknut.
2. To increase the maximum engine poweravailable and the maximum speed of the ATV,
turn the adjusting screw in direction (a). To
decrease the maximum engine power avail-
able and the maximum speed of the ATV, turn the adjusting screw in direction (b). Do not
turn the adjusting screw out more than 12
mm (0.47 in) or the throttle cable could be
damaged. Always make sure the throttle lever
free play is adjusted to 3.0–5.0 mm (0.12–
0.20 in). (See page 8-41.) WARNING! Im-
proper adjustment of the speed limiter and
throttle could cause throttle cable damage
or improper throttle operation. You could
lose control, resulting in an accident.

EBU18722Fuel tank cap
Remove the fuel tank cap by turning it counter-
clockwise.EBU18758FuelMake sure there is sufficient gasoline in the tank.
WARNING
EWB02522Gasoline and gasoline vapors are extremely
flammable. To avoid fires and explosions and
to reduce the risk of injury when refueling, fol-
low these instructions. 1. Before refueling, turn off the engine and besure that no one is sitting on the vehicle. Nev-
er refuel while smoking, or while in the vicinity
of sparks, open flames, or other sources of
ignition such as the pilot lights of water heat-
ers and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the pump nozzle into the fuel
tank filler hole. Stop filling when the fuel
reaches the bottom of the filler tube. Because
fuel expands when it heats up, heat from the
engine or the sun can cause fuel to spill out of
the fuel tank.

NOTICE: Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.

WARNING
EWB02532Gasoline is poisonous and can cause injury or
death. Handle gasoline with care. Never siphon
gasoline by mouth. If you should swallow some
gasoline or inhale a lot of gasoline vapor, or get
some gasoline in your eyes, see your doctor
immediately. If gasoline spills on your skin,
wash with soap and water. If gasoline spills on
your clothing, change your clothes. NOTICEECB00071Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system. Your Yamaha engine has been designed to use
regular unleaded gasoline with a research octane
number of 91 or higher (95 or higher for Europe). If
knocking (or pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance costs.
