The recommended maintenance schedule includes checking the oil level before each ride, replacing the oil every 50 hours of operation, inspecting the air filter every 25 hours, and servicing the brakes every 100 hours. Refer to the owner’s manual for a complete maintenance checklist.
If your Ranger 150 EFI won't start, check the battery connections for corrosion or looseness, ensure the fuel level is adequate, inspect the spark plug for wear, and verify that the key switch is functioning properly.
Use Polaris PS-4 Synthetic 5W-50 Oil, which is specifically formulated for Polaris vehicles and provides optimal performance and protection.
To adjust the throttle, locate the throttle cable adjuster near the handlebar. Loosen the lock nut, adjust the cable tension to achieve the desired throttle response, and then tighten the lock nut securely.
The Ranger 150 EFI includes safety features such as adjustable speed limiting, geofencing capabilities, seat belts, and a safety net for added protection.
To reset the Maintenance Required light, turn the key to the 'ON' position, press and hold the 'MODE' button until the service indicator flashes, and then release the button.
If the vehicle overheats, stop and allow the engine to cool, check the coolant level, inspect the radiator for debris, and ensure that the cooling fan is operating properly.
Enhance performance by regularly maintaining the vehicle, using high-quality fuel, checking tire pressure, and considering aftermarket accessories like a performance exhaust or upgraded air intake.
To change the drive belt, remove the clutch cover, loosen the belt tension, slide the old belt off, and install the new belt by reversing the process. Ensure proper alignment and tension before reattaching the cover.
