PRE-OPERATION CHECKS
EBU19227Inspect your vehicle each time you use it to make sure the vehicle is in safe operating condition. Always
follow the inspection and maintenance procedures and schedules described in the Owner’s Manual.
WARNING
EWB00482Failure to inspect or maintain the vehicle properly increases the possibility of an accident or equip-
ment damage. Do not operate the vehicle if you find any problem. If a problem cannot be corrected
by the procedures provided in this manual, have the vehicle inspected by a Yamaha dealer. Before using this vehicle, check the following points:
ITEMROUTINE PAGE
Fuel • Check fuel level in fuel tank,
and add recommended fuel if neces-
sary.
• Check fuel line for leakage. Correct if necessary. 5-17, 6-3
Engine oil • Check oil level in engine, and add recommended oil to specified
level if necessary.
• Check ATV for oil leakage. Correct if necessary. 6-3, 9-19
Final gear oil • Check ATV for oil leakage. Correct if necessary. 6-3, 9-24
Differential gear oil • Check ATV for oil leakage. Correct if necessary. 6-3, 9-27
Coolant • Check coolant level in reservoir, and add recommended coolant to
specified level if necessary.
• Check cooling system for leakage. Correct if necessary. 6-3, 9-29

8The ATV can be used to cross slow moving, shal-
low water of up to a maximum of 35 cm (14 in) in
depth. Before entering the water, choose your
path carefully. Enter where there is no sharp drop
off, and avoid rocks or other obstacles which may
be slippery or upset the ATV. Drive slowly and
carefully.
Test your brakes after leaving the water. If neces-
sary, apply them several times to let friction dry
out the linings. Do not continue to ride your ATV
without verifying that you have regained proper braking ability. WARNING! Wet brakes may have
reduced stopping ability, which could cause
loss of control.
[EWB02622]
After riding your ATV in water, be sure to drain the
trapped water by removing the check hose at the
bottom of the air filter case and the V-belt cooling
duct check hose. Also, remove the V-belt case
drain plug to drain any water that may have accu-
mulated.
NOTICE: Undrained water can cause
damage or improper operation.
[ECB00842]
Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.

RIDING OVER ROUGH TERRAIN
WARNING
EWB01652Riding improperly over obstacles could cause
loss of control or a collision. Before operating
in a new area, check for obstacles. Never at-
tempt to ride over large obstacles, such as
large rocks or fallen trees. When you go over
obstacles, always follow proper procedures as
described in the Owner’s Manual. Riding over rough terrain should be done with
caution. Look out for obstacles which could cause
damage to the ATV or could lead to an upset or

93. If the coolant is at or below the minimum level
mark, remove panel C to access the coolant
reservoir. (See page 9-10.)
4. Remove the coolant reservoir cap. WARNING! Remove only the coolant res-
ervoir cap. Never attempt to remove the
radiator cap when the engine is hot.
[EWB02672]
5. Add coolant to the maximum level mark, in-stall the reservoir cap, and then install the
panel. NOTICE: If coolant is not available,
use distilled water or soft tap water in-
stead. Do not use hard water or salt water
since they are harmful to the engine. If wa-
ter has been used instead of coolant, re-
place it with coolant as soon as possible,
otherwise the cooling system will not be
protected against frost and corrosion. If
water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
