7The 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 care-
fully.
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 with-
out verifying that you have regained proper brakingability. WARNING! Wet brakes may have re-
duced stopping ability, which could cause loss
of control.
[EWB02621]
After riding your ATV in water, be sure to drain the
trapped water by removing the check hoses at the
bottom of the air filter case. Also, remove the drain
plugs from the front and rear storage compart-
ments and the V-belt case to drain any water that
may have accumulated. NOTICE: Undrained wa-
ter can cause damage or improper operation.[ECB00841]Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.
