Polaris 2016 Sportsman 850, Touring, XP 1000 Owne'rs Manual

Regular maintenance includes checking and changing the oil, inspecting and cleaning the air filter, checking tire pressure, and inspecting the brakes. Refer to the owner's manual for detailed instructions and maintenance intervals.
First, check the battery connections to ensure they are secure and free of corrosion. Make sure the battery is charged. Check the fuel level and ensure the fuel is fresh. If the problem persists, inspect the spark plugs and replace them if necessary.
To improve fuel efficiency, maintain proper tire pressure, use the recommended fuel grade, keep the air filter clean, and perform regular maintenance as outlined in the owner's manual. Avoid aggressive acceleration and heavy loads.
Polaris recommends using their own brand of 4-cycle engine oil, specifically designed for their ATVs. Always check your owner's manual for the correct oil grade and specifications.
Start by checking the battery and fuses. Inspect all wiring for signs of damage or loose connections. Use a multimeter to check for continuity and proper voltage. If the issue persists, consult a professional technician.
Common signs include slipping during acceleration, unusual noises, and a burning smell. Regularly inspect the CVT belt for wear and replace it according to the recommended maintenance schedule.
Adjust the suspension settings by modifying the preload on the shocks. Refer to the owner's manual for guidance on adjusting the suspension according to your weight and riding conditions.
Ensure the radiator is free of debris and the coolant level is adequate. Check the thermostat and cooling fan for proper operation. If overheating persists, it may indicate a more serious issue that requires professional evaluation.
The air filter should be inspected and cleaned every 50 hours of operation or more frequently if riding in dusty conditions. Replacement is typically required every 100 hours, but refer to your owner's manual for specific recommendations.
The recommended tire pressure is usually indicated on a sticker located on the vehicle or in the owner's manual. Typically, it's around 5-7 psi for the front tires and 5-7 psi for the rear tires, but always verify with your specific model's requirements.
