Ensure the battery is fully charged, use the choke if necessary, and allow the engine to warm up for a few minutes before riding.
Use a high-quality 5W-50 synthetic engine oil designed for ATVs, as recommended by Polaris.
Change the oil every 50 hours of operation or every six months, whichever comes first.
Front tires should be inflated to 5 psi (34 kPa) and rear tires to 5 psi (34 kPa) for optimal performance.
Check the battery voltage, inspect the spark plug, ensure fuel is reaching the engine, and verify that the kill switch is in the correct position.
Check for obstructions in the radiator, ensure the cooling fan is operational, and verify that the coolant level is adequate.
Regular maintenance includes changing the oil, checking the air filter, inspecting brakes, and lubricating all grease points every 50 hours of operation.
If the EFI light is on, check for error codes using a diagnostic tool and consult the owner's manual for specific troubleshooting steps.
Ensure regular maintenance, keep the tires properly inflated, and avoid carrying excessive weight to improve fuel efficiency.
Power loss can be caused by clogged air filters, dirty fuel injectors, or worn spark plugs. Regular inspection and maintenance can help prevent these issues.
