8Never 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.
8Always use the size and type tires specified in
this manual.
8Always maintain proper tire pressure as
described in this manual.
8Never modify an ATV through improper instal-
lation or use of accessories.

Use of improper tires on this ATV, or opera-
tion of this ATV with improper or uneven tire
pressure, may cause loss of control, increas-
ing your risk of accident.
Pay attention to the following.

approved by Yamaha Motor Co., Ltd. for
this model. Other tire combinations are
not recommended.
2. The tires should be set to the recom-
mended pressure:

8Check and adjust tire pressures when
the tires are cold.
8Tire 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 condi-
tions. The following are minimums:
Front 17 kPa (0.17 kg/cm
2, 0.17 bar)
Rear 17 kPa (0.17 kg/cm2, 0.17 bar)
4. Use no more than the following pres-
sures when seating the tire beads.
Front 250 kPa (2.5 kg/cm
2, 2.5 bar)
Rear 250 kPa (2.5 kg/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.
