1999 Polaris Sport 400 Owners Manual - Page 5

The following Throttle Lever information, taken from page 38 of your ATV Owner's Manual, has been revised. CONTROL AND PARTS FUNCTIONS Engine Throttle and Choke Throttle Lever Engine speed and vehicle movement are controlled by pressing the throttle lever. The throttle system is spring loaded and engine speed returns to idle when the lever is released. This vehicle is equipped with a Polaris Electronic Throttle Control (ETC) which is designed to reduce the risk of a frozen or stuck throttle. In the event the throttle cable should stick in an open position, the engine will stop and power to the rear wheels will cease when the operator releases the throttle lever. Choke Lever Refer to the engine starting procedure on page 56 for correct choke and throttle settings during starting. Choke Throttle WARNING The Electronic Throttle Control (ETC) stops the engine in the event of a throttle system malfunction and is provided for your safety. Do not attempt to modify the ETC system or replace it with any after market throttle mechanisms. WARNING Do not start or operate an ATV with sticking or improperly operating throttle controls. A stuck or improperly operating throttle could cause an accident resulting in severe injury or death. Always contact your dealer for service repairs whenever throttle problems arise. Failure to check or maintain proper operation of the throttle system can result in the throttle lever sticking during riding and cause an accident. Always check the lever for free movement and return before starting the engine and occasionally during riding.
