    • Make sure that both ignition switches are turned to the off position. There is one on the engine and one on the control panel.

    • Pull the ring near one of the wheel hubs straight out, away from the wheel.

    • Rotate it so that the small roll pin lines up with its slot.

    • Release the ring so that the lock pin slides into the wheel. You may need to rotate the wheels a little before the lock pin fully engages.

    • With the pin engaged, it should be very hard to turn the wheels.

    • Repeat this step so that the lock pins on both wheels are engaged.
