7 The 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 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 wa-
ter that may have accumulated. NOTICE: Und-
rained water 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.
