Important. Read this carefully. SAFETY INFORMATION 7 SAFETY INFORMATION WARNING Read Owner’s Manual Thoroughly before Operation • Carefully read the instructions in every WARN- ING message in the owner’s manual and on every warning label on your JET SKI watercraft before operating. Be sure to observe these instructions. • The owner’s manual and the warning labels pro- vide important safety information. Wear PFD, Protective Clothing and Gear Personal Flotation Device (PFD) • A l l r i d e r s m u s t w e a r a C o a s t G u a r d a p p r o v e d p e r - s o n a l f l o t a t i o n d e v i c e ( P F D ) t h a t i s s u i t a b l e f o r p e r - s o n a l w a t e r c r a f t ( P W C ) u s e . K a w a s a k i r e c o m - m e n d s a v e s t - t y p e P F D . Hard impact with the water can result in loss of consciousness and drowning. • Make sure that your PFD fits correctly so that it does not come off in the water.

8 SAFETY INFORMATION Important. Read this carefully. Wet Suit Bottoms or Other Protective Clothing • A l l r i d e r s m u s t w e a r w e t s u i t b o t t o m s ( n e o p r e n e s h o r t s ) o r c l o t h i n g t h a t p r o v i d e s e q u i v a l e n t p r o t e c - t i o n a g a i n s t p o s s i b l e i n j u r y t o b o d y c a v i t i e s . • N o r m a l s w i m w e a r w i l l n o t p r o v i d e a d e q u a t e p r o - t e c t i o n . Injury from Forced Injection of Water into Body Cavities (Rectum or Vagina) • As a result of falling into water or being near the jet thrust nozzle, water can be forced into body cavities such as the rectum or vagina. This could cause damage to abdominal organs, possibly re- sulting in death or severe injury. A. Jet Thrust Nozzle • Wet suit bottoms are made of a thick material (neoprene) that significantly retards the velocity of water passing through it. • In addition to wet suit bottoms, some other aquatic wear may protect against body cavity injuries. • If wet suit bottoms are not available, you should select clothing that will maximize your protection. Materials that are thicker, have a tighter weave, are water repellent, or that are tighter fitting tend to provide more protection. • Clothing that may be displaced by the force of wa- ter will not provide adequate protection. Other Protective Gear • Wear protective footwear, gloves and goggles (glasses). • Wear suitable eye protection such as goggles while operating the watercraft. Water spray can damage your eyes, or momentarily interfere with your vision, which may lead to an accident. Float- able goggles are recommended. • Wear foot protection such as deck shoes or tennis shoes. Submerged shells, rocks or other objects can injure your feet.
