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, 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
plug to drain any water that may have accumu-
lated. Wash the ATV in fresh water if it has
been operated in salt water or muddy condi-
tions. _

mark, remove panel D. (See pages 8-17–
8-19 for panel removal and installation proce-
dures.)
4. Remove the reservoir cap, add coolant to the
maximum level mark, install the reservoir
cap, and then install the panel.
