Never operate an ATV in fast flowing water or
in water deeper than that recommended in this
manual. Remember that wet brakes may have
reduced stopping ability. Test your brakes after
leaving water. If necessary, apply them several
times to let friction dry out the linings.


Always be sure there are no obstacles or peo-
ple behind you when you operate in reverse.
When it is safe to proceed in reverse, go slowly.


Always use the size and type tires specified in
this manual.


Always maintain proper tire pressure as de-
scribed in this manual.


Never modify an ATV through improper instal-
lation or use of accessories.


Never exceed the stated load capacity for an
ATV. Cargo should be properly distributed and
securely attached. Reduce speed and follow
instructions in this manual for carrying cargo or
pulling a trailer. Allow greater distance for brak-
ing.
