2018-2021 ACE 150 Pre-Ride Inspection

Before you ride your Polaris ACE 150, perform the pre-ride inspection as described in your Owner's Manual. Read, understand and follow all of the instructions, warnings and safety precautions in the Owner's Manual and on all product labels. Failure to follow these instructions, warnings and safety precautions could result in serious injury or death. 

During your pre-ride inspection, do the following:

1. Visually inspect the vehicle, looking for debris, leaks and worn components that may impair the vehicle’s operation.

2. Check the condition of the tires, looking for any sign of punctures or damage, and verify there is adequate tread depth.

3. Check the tire pressures and verify that they are to specification. Tire pressure should be 3 psi (20.7 kPa) for the front tires and 6 psi (41.4 kPa) for the rear tires. 

4. Inspect the front and rear suspension for leaks, debris and damage.

5. Inspect the brake pads and rotors, looking for corrosion, nicks and burrs.

6. Inspect the intake system in the rear of the vehicle for blockage or debris, and clean as needed. Notice: DO NOT spray water directly into the intake system, as this can result in water intrusion to the engine.

7. Inspect the PVT intake for blockage and debris.

8. Ensure the safety flag is properly installed.

9. Next, inspect the fluid levels. Ensure the vehicle is on a level surface before inspecting fluid levels.

10. Inspect the brake reservoir underneath the front of the vehicle for proper fluid level. Add fluid as needed. Tip: Use a flashlight to illuminate the brake fluid reservoir.

11. Next, inspect the engine oil level. Notice: Ensure the oil level is checked on a cold engine. A hot engine will appear overfilled.

  • Remove the oil dipstick and wipe with a clean shop towel.
  • Reinstall the oil dipstick fully and remove to inspect the oil level. Caution: Operating with insufficient, deteriorated or contaminated engine oil will cause accelerated wear and may result in engine or transmission seizure, which could result in loss of control and serious injury or death.
  • Add oil as needed. Caution: Do not overfill. Overfilling can result in loss of engine performance and an oil-saturated air filter. Use a suction device to remove excess oil if overfilled.

12. Inspect the fuel level on the left side of the vehicle and add as needed.

13. Turn the key on and inspect the headlight, taillight and brake light for proper operation.

14. Apply the parking brake, and ensure the vehicle does not roll.

15. Ensure the side nets are properly secured and adjust as needed.

16. Ensure the seat is properly adjusted and secured.

17. Most importantly, check the condition and function of the seat belt.

  • Pull the seat belt completely out and inspect for cuts, wear, fraying, dirt, debris or stiffness.
  • Test the buckle and latch for proper operation.
  • Caution: Always wear a seat belt when riding. The vehicle will limit speed if the seat belt buckle is not latched.

18. Check the steering wheel for smooth operation from full left to full right.

19. Verify proper brake and throttle pedal movement, taking note of any binding or sticking.

20. Start the engine and verify the check engine light is not illuminated.

21. Before allowing children to ride this vehicle, ensure the speed limits are set to your desired setting in the fuse panel. The fuse panel can be accessed by removing the two push rivets on the fuse panel bracket behind the seat. You can adjust speed modes by moving the jumper fuse between the assigned speed slots inside the fuse box. Check your Owner’s Manual for the speed slot adjustments.
