100 MAINTENANCE V ehicle Immersion If your vehicle becomes imm ersed, major engine da mage can result if the machine is not thoroughly inspecte d. T ake the vehicle to your dealer before starting the engine. If it's impossi ble to take your A TV to a dealer before starting it, follow the steps outlined below .
101 MAINTENANCE S p ark Arrestor Failure to heed the following warnings whil e servicing the spark arrestor could result in serious injury or death. Ne ver run the engine in an enclosed area. Remove any combustible materials from the area. Wear eye protectio n and leather work gloves.
102 MAINTENANCE P VT System Failure to comply with the instructions in this warning can result in severe injury or death. Do not modify any component of the PVT system. Doing so may reduce its strength so that a failure may occur at a hig h speed. The PVT system has been precision balanced.
103 MAINTENANCE P VT System The basic operation of the Polaris PVT system is dependent on engine speed and vehicle torque requiremen ts. As engine speed increases, the force exerted on the movable drive sheave by the flyweights also increases. This, in turn, increases th e amount of pinch applied to the drive belt.
104 MAINTENANCE P VT System When T o Use Low Range and High Range PVT Drying There may be some instances when wate r is accidently ingested into the PVT system. Use the following instructions to dry it out before operat- ing. 1. Position the vehicle on a level surface.
105 MAINTENANCE Battery Improperly connecting or disconnecting battery ca bles can result in an explosio n and cause serious injury or death. When removing the battery , always disconnect the negative (black) cable first. When reinstalling the battery , always connect the negative (black) cable last.
106 MAINTENANCE Battery Battery Removal 1. Remove the seat. 2. Disconnect the black (negative) battery cable first. 3. Disconnect the red (positive) battery cable last. 4. Disconnect the battery hold-down strap. 5. On conventional batteries, re move the battery vent tube.
107 MAINTENANCE Battery Battery Inst allatio n Using a new battery that has not been fully char ged can damage the bat- tery and result in a shorter life. It can also hinder vehicle performance. Follow the battery charging instructio ns on page 109 before installing the battery .
108 MAINTENANCE Battery Battery S torage Whenever the vehicle is not used for a period of three mo nths or more, remove the battery from the vehicle, ensure that it's fully char ge d, and store it out of the sun in a cool, dry place. Check battery voltage each month during storag e an d recharge as needed to mainta in a full charge.
109 MAINTENANCE Battery Battery Charging (Conventional Battery) 1. Remove the battery from the vehi cle to prevent dam age from leak- ing or spilled electroly t e du ring charging. See page 106. 2. Charge the battery with a char ging output no larger than 1/10 of the battery’ s amp/hr rating.
110 MAINTENANCE Battery Battery Charging (Sealed Battery) Always verify battery condition befo re and 1-2 hours after the end of charging. State of Charge V oltage Action Charge Time (Using constant cu rrent charger @ standard amps specifie d on top of batt ery) 100% 12.
111 MAINTENANCE Cleaning and St orage W ashing the V ehicle Keeping your Polaris vehicle clean will not only improve its appearance but it can also extend the life of various comp onents. NOTICE: High water pressure may damage comp onents. Polaris recommends washing the vehicle by hand or with a garden hose, using mild soap.
112 MAINTENANCE Cleaning and St orage W ashing the V ehicle If a high pressure water system is u sed for cleaning (not recommended), exercise extreme caution.
113 MAINTENANCE Cleaning and St orage Chrome Wheel Care (if equipped) Proper maintenance will protect chrome wheels from corrosion, pre- serve wheel life and ensure a "like new" appearance for many years. Chrome wheels exposed to road salt (or salt in the air in coastal areas) are more susceptible to corrosion if not properly cleaned.
114 MAINTENANCE Cleaning and St orage Sto r ag e Tips NOTICE: S tarting the engine durin g the storage period will disturb the protective film created by fogging and damage could occur . Never start the engine during the storage peri od. Clean the Exterior Make any necessary repairs and then clean the vehic le as recommended.
115 MAINTENANCE Cleaning and St orage Sto r ag e Tips Fluid Levels Inspect the following fluid levels. Ch ange fluids as r ecommended in the Periodic Maintenance Char t beginning on page 68.
116 MAINTENANCE Cleaning and St orage Sto r ag e Tips Inspect and Lubricate Inspect all cables and lubricate all a reas of the vehicle as recommende d in the Periodic Maintenance Chart beginning on page 68. Battery Maintenance Remove the battery and rechar ge it as outlined on page 109.
117 MAINTENANCE T ransporting the A TV 1. S top the engine. 2. Place the transmission in P ARK. 3. Lock the parking brake. 4. Secure the fuel cap, oil cap and seat. 5. Always tie the frame of the A TV to the transporti ng unit securely with suitable straps or rope.
118 ADJUSTMENTS Throttle Body/Idle RPM Idle RPM is preset by the manufactur er . If the engine idle speed is not satisfactory , please see your Pola ris dealer for adjustment. Throttle Cable Freeplay 1. Remove the three cover screws from the right han- dlebar control and remove the cover .
119 ADJUSTMENTS Throttle Cable Freeplay 4. Place the transmission in P ARK. Lock the parking brake. 5. Start the engine and allow the idle to stabilize.
