II. SAFETY
WARNING! Adding accessories,
oversize batteries, or a different
seat will increase the weight of
your mobility device. Verify with your
authorized Pride Provider that the
total weight of your mobility device,
including additions, does not
exceed the maximum weight
allowance.
WARNING! Never exceed the
maximum lifting capacity of a lift
regardless of the class of hitch being
used. Doing so may cause lift and/or
vehicle damage.

exceed the maximum tongue weight
capacity of your vehicle.
HITCH CLASS INFORMATION
Hitches come in a variety of sizes and are designated by class. The classes range from Class I to Class IV. A
heavier load requires a larger class, which has a higher tongue weight. Tongue weight is the amount of weight
(downward force) that the load puts on the hitch. See figure 1.
The combined weight of your lift and mobility device gives you the minimum tongue weight for your application.
Exceeding the tongue weight of a hitch creates an unsafe driving situation and can damage the hitch and/or the
vehicle. See figures 2 and 3.
