ADULT SECTION Maintenance Slider Replacement Polaris rail slides have a wear limit indicator groove to indicate the minimum permissible slide thickness. Replace the rail slides if they are worn to the top of the groove at any point along their length. Failure to do so may result in permanent damage to the track or rails. Minimum Thickness Replace when worn to top of groove Track Lubrication Track failure, loss of vehicle control and braking ability can result from extended use of this vehicle on surfaces providing marginal lubrication between the slider and track guide clips. Examples of marginal lubrication would include lakes without snow cover, icy trails and no-snow conditions. The slide rail is designed to operate in conditions with adequate snow cover in order to provide sufficient lubrication. Excessive wear indicates insufficient lubrication. A new slider can cause faster heat build up in limited lubrication than a used slider, resulting in excessive wear. NOTE: Track damage or failure caused by operation on ice or poor lubrication conditions may void the track warranty. Steering System The steering systems on Polaris snowmobiles can be adjusted with ski toe alignment. Improper toe alignment can cause erratic steering. See your dealer for adjustments. WARNING Improper alignment or adjustment may cause loss of steering control, resulting in serious injury or death. Do not attempt to change the ski alignment. See your Polaris dealer. 68
