SAFETY WARNINGS AND GUIDELINES
Please read this entire manual before using this device, paying extra attention to these
safety warnings and guidelines. Please keep this manual in a safe place for future reference.
Ensure that any surface this cart will be placed on is sufficiently robust to support
the combined weight of the cart and installed displays, as well as that of any
persons moving the cart into place.
This cart can support four displays weighing up to 100 lbs. (45kg) each for a total of
400 lbs. (181kg). Exceeding the rated weight capacity can result in damage to the
equipment or severe personal injury.
Visually inspect the cart periodically and after it is transported to ensure that all
parts are secure and that all screws are tight. Do not use the cart if any parts are
damaged or missing.
Do not install anything other than four flat-screen displays on this cart. Other loads
could change the center of balance and cause the cart to tip over, resulting in
equipment damage and possible serious injury.
While much of this cart can be assembled by a single person, final assembly, display
installation, and final adjustment should be performed by two people.
