Polaris Sportsman Touring 850 Owner's Manual

To perform an oil change, warm up the engine, turn it off, and place the ATV on a level surface. Remove the drain plug and oil filter, allow the oil to drain completely, then replace the filter and drain plug. Refill with the recommended oil type and quantity.
The recommended oil type is Polaris PS-4 5W-50 or a high-quality synthetic 5W-50 engine oil. Always refer to your owner's manual for confirmation.
First, check the battery connections and charge. Ensure the fuel is fresh and the fuel valve is open. Inspect the spark plug for dirt or damage and replace if necessary. If the problem persists, consult a professional technician.
Regular maintenance includes checking and changing the oil, inspecting the brakes, lubricating the throttle and brake cables, checking the tire pressure, and cleaning or replacing the air filter.
To improve fuel efficiency, maintain proper tire inflation, perform regular maintenance, avoid excessive idling, and use the recommended fuel type. Riding smoothly and avoiding rapid acceleration can also help.
Check the coolant level and ensure there are no leaks. Make sure the radiator is clean and free of obstructions. Inspect the fan operation. If overheating persists, have the cooling system checked by a professional.
To adjust the suspension, refer to the owner's manual for specific settings. Use the preload adjuster located on the shocks to increase or decrease the stiffness based on your weight and riding conditions.
Common electrical issues include blown fuses, faulty connections, and battery problems. Check all fuses and replace any that are blown. Inspect wiring connections for corrosion or damage, and clean or repair as needed.
Remove the air filter cover and take out the filter. Clean it with compressed air or wash it with a mild detergent if reusable. Ensure it is completely dry before reinstalling. Replace it if it shows signs of wear or damage.
Check for fuel delivery issues, such as clogged filters or lines. Inspect the spark plug and replace it if necessary. Ensure the air filter is clean. If the problem continues, consult a technician for a thorough inspection.
