Operator Safety
WARNING
POTENTIAL HAZARD
Carrying a passenger on an ATV.
WHAT CAN HAPPEN
Carrying a passenger greatly reduces the operator's ability to
balance and control the ATV, which could cause an accident and
injury to the operator and/or passenger.
HOW TO AVOID THE HAZARD
Never carry a passenger. The purpose of the long seat is to allow
the operator to shift position as needed during operation. It is not
intended for carrying passengers.
