Test your brakes after leaving the water. Do not
continue to ride your ATV without verifying that
you have regained proper braking ability.CAUTION:_ 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
check hose on the V-belt cooling duct. Wash
the ATV in fresh water if it has been operated in
salt water or muddy conditions. _
