The recommended maintenance schedule includes checking the oil and filter every 50 hours, inspecting the drive belt every 100 hours, and changing the coolant every 500 hours. Regularly check tire pressure, brakes, and the battery.
If experiencing starting issues, check the battery connections for corrosion, ensure the battery is charged, inspect the spark plugs, and verify that the fuel is fresh and reaching the engine.
Polaris recommends using their PS-4 Extreme Duty 10W-50 synthetic oil, especially for operating in extreme conditions. Regular 10W-40 oil can be used for typical conditions.
To adjust the drive belt, first ensure the vehicle is off and cool. Remove the clutch cover, inspect the belt for wear, and adjust the tension using the tensioner pulley. Reinstall the cover once adjusted.
If overheating occurs, check the coolant level and top it off if necessary. Ensure the radiator is unobstructed and clean. Inspect the thermostat and the cooling fan for functionality.
To improve fuel efficiency, maintain proper tire pressure, perform regular maintenance, reduce excess weight, and avoid prolonged idling. Driving at moderate speeds can also help.
For winter storage, clean the vehicle thoroughly, change the oil and filter, top off fluids, disconnect the battery, and store it in a dry place. Use a cover to protect from dust.
To replace the air filter, locate the air box, remove the cover, take out the old filter, and insert a new one. Ensure the filter is seated properly and reattach the cover securely.
If the transmission is slipping, check the drive belt for wear, ensure it is properly tensioned, inspect the clutches for damage, and verify that the transmission fluid is at the correct level.
Enhance off-road capability by installing all-terrain tires, upgrading the suspension, adding skid plates, and using a lift kit for additional ground clearance. Regular maintenance also ensures peak performance.
