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.


Never modify an ATV through improper instal-
lation or use of accessories.


Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow
instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.

PRE-OPERATION CHECKS
Before using this machine, check the following points:
ITEM ROUTINE PAGE
BrakesCheck operation, free play, fluid level and fluid leakage.
Fill with DOT 4 brake fluid if necessary.5-7 ~ 5-9,
8-91 ~ 8-105
FuelCheck fuel level.
Fill with fuel if necessary.5-11 ~ 5-13
Engine oilCheck oil level.
Fill with oil if necessary.5-15 ~ 5-17,
8-33 ~ 8-43
Coolant reservoirCheck coolant level.
Fill with coolant if necessary.8-55 ~ 8-65
Final gear oil/
Differential gear oilCheck for leakage.5-19 ~ 5-21,
8-43 ~ 8-53
ThrottleCheck for proper throttle cable operation. 5-23, 8-89
Wheels and tiresCheck tire pressure, wear and damage.5-27 ~ 5-33,
8-113 ~ 8-115

2. The tires should be set to the recommend-
ed pressure:

Recommended tire pressure
Front 35 kPa (0.35 kgf/cm
2, 0.35 bar)
Rear 30 kPa (0.30 kgf/cm2, 0.30 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 32 kPa (0.32 kgf/cm
2, 0.32 bar)
Rear 27 kPa (0.27 kgf/cm2, 0.27 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
