Polaris 600 Rush. 800 Rush Owner's Manual

To properly break in your Polaris 600 Rush engine, operate the snowmobile at various throttle positions without using full throttle for the first 5 hours. Avoid prolonged operation at constant RPMs and use short bursts of acceleration.
Start by checking the fuel level and battery charge. Ensure the kill switch is in the 'run' position and inspect the spark plugs for wear or fouling. If problems persist, inspect the fuel lines and replace the fuel filter if needed.
Polaris recommends using their VES (Variable Exhaust System) synthetic oil for optimal performance and protection of the engine components.
To adjust the suspension, start by setting the front and rear shock preload to match your weight and riding style. You can also adjust the compression and rebound settings on the shocks to improve handling and comfort on trails.
Regular maintenance includes checking and cleaning the clutches every 500 miles, inspecting and adjusting the track tension and alignment every 1,000 miles, and performing an oil change and filter replacement every season or 1,000 miles, whichever comes first.
Improve fuel efficiency by maintaining proper track tension, ensuring the engine and clutches are clean and in good condition, and by avoiding prolonged idling. Riding at a steady pace and reducing weight can also help.
If your Polaris 600 Rush overheats, stop the engine immediately and let it cool down. Check the coolant level and inspect for leaks. Ensure the radiator and cooling fins are clean and unobstructed. If the problem persists, consult a professional mechanic.
To replace the drive belt, remove the clutch guard, then open the secondary clutch sheaves by rotating the clutch spreader tool. Slip the old belt off and install the new belt, ensuring it is seated properly in the clutch sheaves. Reinstall the clutch guard.
The recommended track tension for a Polaris 600 Rush is approximately 3/8 inch (9.5 mm) of slack when measured midway between the track clips. Adjust the tension using the adjuster bolts on the rear suspension until the correct tension is achieved.
To winterize your Polaris 800 Rush, clean the exterior and dry it thoroughly. Add a fuel stabilizer to the fuel tank, run the engine briefly, and then fog the engine cylinders. Disconnect the battery and store it in a cool, dry place. Cover the snowmobile with a breathable cover.
