MAINTENANCE AND LUBRICATION Lubrication Oil Pump Bleeding Procedure 1. Fill the oil reservoir with Polaris injector oil. 2. Loosening the bleeder screw is only necessary when the oil supply line has been disconnected from the pump or the oil reservoir and supply line have been completely run out of oil. In these cases, loosen the pump bleed screw one full turn. Allow oil to flow from the bleed screw for five to ten seconds. Tighten bleed screw. CAUTION Never run the engine with the bleed screw loose. Loss of oil will cause serious engine damage. 3. Start the engine and rotate the oil pump lever to its full open position. With the engine at idle, hold the lever up for thirty seconds to make sure all air is out of the system. Throttle Cable Adjustment 250 and 400 Engines Vehicles with 250 and 400 engines do not utilize a cable sleeve jam nut. You will need to bottom the cable to the carburetor slidevalve cap. Adjust at throttle cable adjuster near the throttle block. See page 137 for adjustment procedure. Oil and Filter Change The recommended oil change interval is 100 hours, 1000 miles, or every six months, whichever comes first. Suggested break in oil change is at 20 hours, 200 miles, or one month, whichever comes first. Severe use operation requires more frequent service. Severe use includes continuous duty in dusty or wet conditions, and cold weather riding. NOTE: Severe use cold weather riding is all riding below 10° F, and riding between 10° F and 30°F when most trips are slow speed and less than 5 miles. Be sure to change the oil filter whenever changing oil Oil may be hot. Do not allow hot oil to come into contact with skin as severe burns may result. CAUTION 108
