WARNING
EWB01640Never operate this ATV in fast flowing water or
in water deeper than that specified in your
Owner’s 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 lin-
ings. If the ATV is operated through deep or
fast flowing water, the tires may float, causing
loss of traction and loss of control, whichcould lead to an accident.Test your brakes after leaving the water. Do not
continue to ride your ATV without verifying that you
have regained proper braking ability.
CAUTION:ECB00280After 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, the V-belt
cooling duct check hose, the drive select lever
box check hose and the storage compartment
check hose. Also, remove the V-belt case drain
