28 THE PERFECT FIT F ront Suspension Adjustments Independent F ront Suspension (IFS) Break in the suspension for about 150 miles (240 km) before making any fine-tuning adjustments. Settings will vary from ri der to rider , depending on rider weight, vehicle speed, riding style, an d trail conditions.
29 THE PERFECT FIT F ront Suspension Adjustments Independent F ront Suspension (IFS) For the best ride, the suspension should be adjusted to use the full travel of the shocks with occasional light bottoming.
30 THE PERFECT FIT F ront Suspension Adjustments Shock Damping (Indy Select Shock) Adjustments to the compression stif f- ness of Indy Select sh ocks can be made by turning the adjustment screw located near the base of the shock ( + ). This adjustment is the easiest to per- form and it shou ld be considered first.
31 THE PERFECT FIT F ront Suspension Adjustments Spring Preload Increasing spring preload will increase ski-to-ground pressure. Decreasing spring preload will decrease ski-to- ground pressure. Wh en adjusting, be sure the springs on both the left and right sides of the machine are at the same adjustment.
32 THE PERFECT FIT Rear Suspension Adjustments Rider weight, riding style, trail co nditions, and vehicle speed all af fect suspension action. Each rear suspension can be adjusted to suit rider preference and deliver excellent performance for a given set of conditions.
33 THE PERFECT FIT Rear Suspension Adjustments Suspension Performance Tips • Rider weight usually determines th e position at which the spring pre- load should be set. However , this ma y vary with riding style. W ith a little experimentation, each rider can find a preferred se tup.
34 THE PERFECT FIT EDGE Rear Suspen sion Adjustments Initial Spring Preload Setting (Sag Method) T o set up the EDGE rear suspen- sion torsion spring preload , mea- sure the distance between the ground and rear bumper .

50 PRE-RIDE INSPECTIONS Before Starting the Engine n Steering System Before driving, manually tu rn the skis to the left and right to be sure ice and snow are not interfering with full left and right steering. If dif ficulty is encountered, remove ice and snow build-up that may be obstru cting the steering linkage.
51 PRE-RIDE INSPECTIONS Start the Engine and Check Before starting the engine, always re fer to all safety warnings pertaining to snowmobile operation. Never en gage the starter when the engine is running. Never start the engine with out checking all ve hicle components to be sure of proper operation.
52 OPERA TION Starting the Engine 1. T urn the fuel valve on. See page 56. 2. T urn the key to the ON position. 3. Pull the engine stop switch up to the RUN posit ion. 4. If starting a cold engine, flip the choke toggle to FULL CHOKE. Do not use the choke if starting a warm engine.
53 OPERA TION Engine Break-In No single action on your part is as important to long, trouble-free machine life as proper break-in of a new or rebuilt engine. Premix the first tank of fuel with one pint of Polaris injection oil for each five gal- lons of fuel.
54 OPERA TION Engine Break-In Oil Injection System Always check and fill the oil tank when refueling. See page 58. Oil Recommendations Engine lubrication comes from oil ad ded to the fuel and oil injection systems. Polaris recommends the us e of Premium 2 Cycle Oil for this engine.
55 OPERA TION T rack W arm-Up Follow these steps to ensure proper warm-up of the engine, drive train and track. 1. Use an appropriate stand to securely support the rear of the snowmobile at the rear bumper . The trac k should be about 4 I (10 cm) of f the ground.
56 OPERA TION F uel V alve T urn the fuel valve clockwise to OFF to shut off the fuel supply . T urn the valve counter- clockwise to ON to turn the fuel supply on. Fu e l WAR N I N G Gasoline is h ighly flammable and e xplosive under certain con ditions.
57 OPERA TION Fu e l Y our Polaris en gine is designed to run on 87 octane non-oxygenated or 89 octane oxygenated pump gasoline. There's a great deal of variability in the quality of the 87 octane gaso line available across the country , so we encourage the use of premium fuel when possible.
58 OPERA TION n Oil Low Oil Indicator Light The low oil indicator light will alert th e operator if the oil level is low . V isually check for oil in the bottle.
59 OPERA TION Carburetion Proper carburetor adjustment is c ritical. A lean mixture (too muc h air , too little fuel) may result in piston bu rning, bearing failure, or complete engine failure. A rich mixture (too much fuel, too little air) may foul plugs and cause generally poor engine performance.
60 OPERA TION Carburetion Jetting Guidelines Changes in altitude and temperatur e af fect air density , which is the amount of oxygen available for com bustion. In low elevations and cold temperatures, the air has more oxygen . In higher elev ations and high er temperatures, the air is less dense.
61 OPERA TION n Engine Stop Switch Push down on the engine stop switch ( + ) to ground out the ig nition and stop the engine quickly . Pull the switch up to the ON position to allow restarting.
62 OPERA TION Throttle Lever If the engine stops abruptly when the throttle lever is released: 1. T urn the ignition switch to OF F . 2. V isually inspect the throttle cable and carburetor to determine what caused the safety switch to activate. 3. T est the throttle lever by compr essing and releasing it several times.
63 OPERA TION Emergency Stoppi ng The following chart lists methods for stopping the snowmobile in the event of an emergency . See page 61 for more information about the engine stop switch and throttle safety switch.
64 OPERA TION Reverse Operation WAR N I N G Improper reverse operation, even at low speeds, may cause loss of control, resulting in serious injury or death. Damage will occur to the chaincase or transmission if shifting is attempted w hen the engine is operating above idle speed.
65 OPERA TION Reverse Operation Electronic R everse (PERC t ) Electronic reverse will activate only if the engine RPM is below 4000. If your machine is running at an altitude of o ver 6000 feet, adjust the igni- tion setting as described below . Always make sure the ve hicle is stopped and the engine is running at id le before shifting to reverse.
66 OPERA TION Reverse Operation Electronic R everse (PERC t ) Disengaging Reverse 1. S top the snowmobile and leave the engine idling. 2. Push the yellow reverse button for one second and release. The engine will slow and begin to rotate forward. The light on the instrument panel will shut off.
67 OPERA TION Daily Storage At the end of each ride, park the snow- mobile on a level surfa ce and support it at the rear with an appropriate track stand. The track should be suspended approxi- mately 4 I (10 cm) off the ground. Remove the key and cover the machine.

77 MAINTENANCE Lubrication n Chaincase Oil Check the chaincase oil level at th e intervals outlined in the mainte- nance charts beginning on page 70 . Change the chaincase oil after the first 500 miles (800 km), then every 10 00 miles (1600 km) or season- ally .
78 MAINTENANCE Spark Plugs A new engine can cause temporary spar k plug fouling du e to the preser- vative added during the assembly p rocess. A void prolonged idle speeds, which cause plug fouling and carbonization. Refer to y our Owner's Manual Supplement for th e specific spark plug to be used in your machine.
79 MAINTENANCE Spark Plugs Normal Plug The normal insulator tip is gray , ta n or light brown. There will be few combustion deposits. The electrodes are not burned or eroded. This indi- cates the proper type and heat range for the engine and the service.
80 MAINTENANCE Intake Filters The intake foam filter ( + ) limits snow ingest ion into the intake system. When operating in loose powder snow , check the top of the foam filter periodically to remo ve any accumulation o f snow . CA UTION Operating the snowmo bile with the inta ke filters removed may cause ca rbu- retor icing.
81 MAINTENANCE F uel Filter/F uel Lines The fuel filter is located inside th e fuel tank. This component requires no maintenance. Inspect the fuel lines regularly for signs of deteriorat ion or damage. Always check fuel line condition after periods of sto rage.
82 MAINTENANCE Carburetor W ater/Sediment T rap Service Most Polaris snowmobiles contain pa tented carburetor bowl water/sedi- ment traps located at the bottom of each carburetor . The trap, consisting of a hose with a plug, sh ould be drained at least every 2000 miles (3 200 km) and inspected for contamination.
83 MAINTENANCE Carburetor The number stamped in the end of the main jet indicates the jet size. The jet installed at the time of manufacture is not necessarily correc t for your elevation. It's your dealer's responsi bility to make sure the correct main jet is installed.
84 MAINTENANCE Exhaust System Check the exhaust system for wear or damage at approx imately 2000 miles (3200 km). T o inspect, allow the engine and exhaust system to cool completely . Open the hood an d inspect the muffler and pipes for cracks or damage.
85 MAINTENANCE Brakes n Hydraulic Brake Inspection Inspect the brake lever reserve before each use of the snowmobile. See page 47. Brake pads must be replaced when the brake pad material becomes thin- ner than the backing pl ate (approximately 1/16 I ).
86 MAINTENANCE Brakes Brake Fluid On some models , the brake fluid le vel can be seen through a plastic sight glass in the brake reservoir . If the fluid is suff icient, the sight glass will be black. If the sight glass is an y color other than black, add brake fluid.
87 MAINTENANCE Brakes Bleeding the Hydraulic Brake System Air in the hydraulic brak e system will cause spon gy brake lever action. Bleed the system before operating the snowmobile. During the bleeding proc edure, keep the brake handle as leve l as possi- ble.
88 MAINTENANCE Lights Headlight Adjustment The headlight may be a djusted for ve rtical aim using the following pro- cedure. 1. Place the snowmobile on a level surface with the headlight approxi- mately 25 feet (7.6 m) from a wall. 2. Measure the distance from the floo r to the center of the headlight and make a mark on the wall.
89 MAINTENANCE Lights NOTE: Do not touch a halogen bulb with bare fingers. Oil from skin leaves a residue, causin g a hot spot that will shorten the life of the lamp. Headlight Bulb Removal 1. Pinch the ends of the spring (1) together and lift until it releases from the spring retainer .
90 MAINTENANCE Clutch System Periodically inspect clutch sheaves for damage, wear or belt residue. T o maintain optimum performance, clean with non-oil based cleaners such as isopropyl alcohol. Clutch Alignment Offset Clutch alignment offset i s import ant for maintaining optimum perfor- mance.
91 MAINTENANCE Clutch System n Drive Belt Condition Belt width and length must match the center distance of the clutches and sheave width of the drive clutch. For this reason, Polaris recommends that only O.E.M. belts be used. Ot her belts may match the dimensions, but can drastically change the shif t pattern, resulting in poor perfor- mance.
92 MAINTENANCE Clutch System Drive Belt Removal 1. S top the engine after operating in a forward motion. 2. T urn the ignit ion key off. W ait fo r the engine to stop completely . 3. Lock the parking brake (if equipped). 4. Open the hood. 5. Remove the clutch guard retain- ing pin and open the clutch guard.

94 MAINTENANCE Clutch System n Drive Belt Deflection Measure belt deflection with both clutches at rest and in their full neutral position. Place a straight edge (1) on the belt and ap ply downward pres- sure while measuring at point 2. This meas urement should be 1 1/4 I (3.
95 MAINTENANCE Clutch System To r q u e S t o p If your snowmobile is equippe d with an engine torque stop, periodically check torque stop clearance. W ith clutches in proper alignment, the torque stop clearance should be .010 I -.030 I (.25-.75 mm) from the engine case.
96 MAINTENANCE Tr a c k T rack Inspection 1. Using a hoist, safely lift and support the rear of the snow- mobile of f the ground. 2. Rotate the track by hand to check for damage. 3. Carefully examine the track along the entire length of each rod ( + ).
97 MAINTENANCE Tr a c k T rack Lubrication The slide rail needs snow for lubrication. Excessive wear indicate s insufficient lubrication. A new rail slide can cause faster heat build-up in limited lubrication, resulting in excessive wear . NOTE: If excessive rail slide wear occurs due to poor snow con ditions, additional wheel kits are available.
98 MAINTENANCE Tr a c k T rack T ension T rack adjustment is critical for prop er handling. Always maintain cor- rect tension and alignment. NOTE: T ension adjustments should be ma de only after the track is warmed up and lim ber . 1. T urn the engine off.
99 MAINTENANCE Tr a c k T rack T ension If the track needs adjustment: 5. Loosen the rear idler shaft bolt. 6. Loosen the locknuts. 7. T ighten or loosen th e track adjus ting screws to provide equal adjust- ment on both sides of th e track. 8. Repeat the measurement o n the other side of the track.
100 MAINTENANCE Tr a c k n T rack Alignment Periodically check that the track is centered and runnin g evenly on the slide rails. Misalignment will cause excessive wear to the track and slide rail. 1. Safely support the rear of the ma chine with the track of f the ground.
101 MAINTENANCE Steering System Steering Inspection and Adjustment Each week, or before a long ride, ch eck all steering system fasteners and tighten if necessary .
102 MAINTENANCE Steering System Ski Alignment W ith the handlebars in a st raight ahead position, and with veh icle weight compressing the suspension, measure from the straight e dge of the skis at the center of the sk i mounting bolt.
103 MAINTENANCE Steering System n Ski Skags Check skags before each use of the snowmobile to ensu re positive steer- ing characteristics. Skags must be replaced when worn to half their orig- inal diameter . NOTE: Carbide skags must b e replaced if any abnormal wear or chip- ping is found.
104 MAINTENANCE Steering System n Rail Slide Wear For ease of inspection, all Polaris rail slides have a wear limit indicator groove to indicate the minimum per- missible slide thickness. Replace the rail slides if they are worn to the top of the groove at any point along their length.
105 MAINTENANCE Extended Storage Off-season or extended storage of your snowmobile requires preventive measures to aid against deterioration and to prolong the useful life of many componen ts.
106 MAINTENANCE Extended Storage Bearings Grease the drive shaft clutch side bearing with Polaris Premium All- Season Grease or a similar high qu ality grease to prevent corrosion. Clutch and Drive System Remove the drive belt and store in a cool dry location.
107 MAINTENANCE Extended Storage Engine and Carbur etor Protection Using a fuel stabilizer and topping of f the fuel tank eliminates the need to drain the fuel system. If you prefer to drain the fuel tank, use the fol- lowing procedure 1. T ransfer unused fuel from the fuel tank to an ap proved fuel con- tainer using a siphon pump.
108 MAINTENANCE Extended Storage Electrical Connections Separate electrical connector blocks and clean corrosive build-up from connectors. Lubricate or pack conn ector blocks with dielectric grease and re-connect . Replace worn or frayed electrical wi re and connec tors.
