To install the wheels, slide the axle through the hole in one side of the frame. Install the components in the following order: washer, wheel, washer, washer, wheel, washer. Continue sliding the axle through the frame until it reaches the hole on the opposite side.
Next, position the wheels so they sit tightly against the inside of the frame on each side.
Insert a retaining pin into the hole at one end of the axle to secure the components in place. Then repeat the same step on the opposite side by inserting the second retaining pin to fully secure the wheel assembly.
