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
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, the V-belt cooling duct
check hose and the rear storage compartment
check hose. Also, remove the V-belt case drain
plug and front storage compartment drain plug to
drain any water that may have accumulated.
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.

EBU23932V-belt case drain plugAfter riding in water deep enough to allow it to en-
ter the V-belt case, remove the V-belt case drain
plug to drain the water from the case.TIPIf water drains from the V-belt case after removing
the plug, have a Yamaha dealer check the ATV as
the water may affect other engine parts.
EBU23941Adjusting the carburetorThe carburetor should be checked and, if neces-
sary, adjusted at the intervals specified in the pe-
riodic maintenance and lubrication chart. The
carburetor is an important part of the engine and
requires very sophisticated adjustment. There-
fore, most carburetor adjustments should be left
to a Yamaha dealer, who has the necessary pro-
fessional knowledge and experience. The adjust-
ment described in the following section, however,
may be performed by the owner as part of routine
maintenance.NOTICEECB00481The carburetor has been set and extensively
tested at the Yamaha factory. Changing these
settings without sufficient technical knowl-
edge may result in poor performance of or
damage to the engine. EBU24011Adjusting the engine idling speedThe engine idling speed must be checked and, if
necessary, adjusted as follows at the intervals
specified in the periodic maintenance and lubrica-
tion chart.
