Use Polaris PS-4 Synthetic 4-Cycle All-Season Engine Oil or a similar 0W-40 synthetic oil for optimal performance.
It is recommended to change the oil every 50 hours of operation or every 6 months, whichever comes first.
The recommended tire pressure is 5 psi (34.5 kPa) for both front and rear tires.
Check the fuel level, ensure the battery is charged, inspect the spark plug for wear, and verify the kill switch is in the "Run" position.
Regular maintenance includes checking and changing the oil, inspecting the air filter, checking tire pressure, and tightening any loose bolts.
Loosen the rear axle bolts, adjust the chain tension using the adjusters, and tighten the bolts once the desired tension is achieved.
Use a premixed 50/50 solution of antifreeze and distilled water, or Polaris Antifreeze 60/40 Premix.
Maintain proper tire pressure, perform regular engine maintenance, and avoid excessive idling or aggressive driving.
Stop the engine immediately, let it cool down, check coolant levels, and inspect for any leaks or blockages in the cooling system.
Remove the air filter cover, take out the filter, wash it with warm soapy water, rinse thoroughly, let it dry, and lightly oil before reinstalling.
