Always be careful when skidding or sliding.
Learn to safely control skidding or sliding by
practicing at low speeds and on level, smooth
terrain. On extremely slippery surfaces, such
as ice, go slowly and be very cautious in order
to reduce the chance of skidding or sliding out
of control.
Never operate an ATV in fast flowing water or
in water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.
Always be sure there are no obstacles or peo-
ple behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly.
Always use the size and type tires specified in
this manual.
Always maintain proper tire pressure as de-
scribed in this manual.

1-PRE-OPERATION CHECKS
Before using this machine, check the following points:
ITEM ROUTINE PAGE

Fill with DOT 4 brake fluid if necessary.5-5–5-7,
8-45–8-49
Rear brakeCheck operation, condition and free play.
Adjust if necessary.5-5–5-7,
8-51–8-55

Tires
Always use the recommended tires.
WARNING
Use of improper tires on this ATV, or operation
of this ATV with improper or uneven tire pres-
sure, may cause loss of control, increasing
your risk of accident.
Pay attention to the following.
1. The tires listed below have been approved
by Yamaha Motor Co., Ltd. for this model.
Other tire combinations are not recom-
mended.ACE-01EACE-01E

2. The tires should be set to the recommend-
ed pressure:
Recommended tire pressure
Front 20 kPa (0.20 kgf/cm
2, 0.20 bar)
Rear 25 kPa (0.25 kgf/cm2, 0.25 bar)
Check and adjust tire pressures when the
tires are cold.
Tire pressures must be equal on both
sides.
3. Tire pressure below the minimum speci-
fied could cause the tire to dislodge from
the rim under severe riding conditions.
The following are minimums:
Front 17 kPa (0.17 kgf/cm
2, 0.17 bar)
Rear 22 kPa (0.22 kgf/cm2, 0.22 bar)
4. Use no more than the following pressures
when seating the tire beads:
Front 250 kPa (2.5 kgf/cm2, 2.5 bar)
Rear 250 kPa (2.5 kgf/cm2, 2.5 bar)
Higher pressures may cause the tire to
burst. Inflate the tires very slowly and
carefully. Fast inflation could cause the
tire to burst.

How to measure tire pressure
Use the low-pressure tire gauge.NOTE:The low-pressure tire gauge is included as stan-
dard equipment. Make two measurements of the
tire pressure and use the second reading. Dust or
dirt in the gauge could cause the first reading to be
incorrect.Set pressure with tires cold.
Set tire pressures to the following specifications:ACE-02EACE-02E

To decelerate:
When slowing down or stopping, release the throt-
tle and apply the brakes smoothly and evenly. As
you slow down, shift to a lower gear. Be sure that
the engine has sufficiently slowed before engaging
a lower gear. Improper use of the brakes or shift-
ing can cause the tires to lose traction, reducing
control and increasing the possibility of an acci-
dent.
WARNING
Make sure the engine has sufficiently slowed
before shifting to a lower gear. Engaging a low-
er gear when the engine speed is too high
could make the wheels stop rotating. This
could cause loss of control, an accident and
injury. It could also cause engine or drive train
damage.

WARNING
_ Always use the size and type tires specified in
the Owner’s Manual for this vehicle on pages
5-19–5-21. Always maintain proper tire pres-
sure as described in the Owner’s Manual on
page 5-23. Use of improper tires on this ATV,
or operation of this ATV with improper or un-
even tire pressure, may cause loss of control,
increasing your risk of an accident. _Do not operate at speeds too fast for your
skills or the conditions.
WARNING
_ Always go at a speed that is proper for the ter-
rain, visibility and operating conditions, and
your experience. Operating this ATV at speeds
too fast for your skills or the conditions in-
creases your chances of losing control of the
ATV, which can result in an accident. _
