The ATV can be used to cross slow moving, shal-
low water of up to a maximum of 11 cm (4 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
carefully.
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
without verifying that you have regained proper braking ability.
WARNING! Wet brakes may have
reduced stopping ability, which could cause
loss of control.
[EWB02622]
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. NOTICE: Undrained
water can cause damage or improper opera-
tion.
[ECB00842]
Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.
