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
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. Also, remove the drain
plugs from the storage compartment and the V-
belt case to drain any water that may have accu-
mulated. NOTICE: Undrained water can cause
damage or improper operation.
[ECB00842]
Wash the ATV in fresh water if it has been operat-
ed in salt water or muddy conditions.

WARNING
EWB01652Riding improperly over obstacles could cause

ge rocks or fallen trees. When you go over
obstacles, always follow proper procedures as
described in the Owner’s Manual. Riding over rough terrain should be done with
caution. Look out for obstacles which could cause
