PACKING TIPS
The postal service often handles the packages roughly, so it is important to package everything well.
NB!!! When packaging, ensure that the motor plate is firmly secured in a box and must not move in the box. The paddle wheel is
balanced and vulnerable.
Use a sturdy box. If necessary, use some towels, bubble wrap, pillow, etc... to wrap everything properly. Also put a note in the box with your details.
