REQUIREMENTS FOR PROPER OPERATION
A. You must have a two (2) inch square receiver type
hitch on your towing vehicle that aligns within two
(2) inches of the height of the tow bar.
NOTE: The tow bar may slope upward toward the
towing vehicle, but should not slope downward
toward the towing vehicle.
The AutoStop needs a level push on the ball
mount tube to operate properly. This requires that
the height of the
receiver tube be
adjusted rather than the
height of the ball as
happens normally.
There are several
options available if you
need to adjust the
receiver tube height.
A two (2) inch drop can
be achieved by welding
another receiver tube
under the existing
receiver tube. (Figure 1)
A six (6) inch drop
receiver is available that
pins into the existing
receiver. (Figure 2)
The AutoStop shown in Figure 3 is set up as it
comes from the factory.
The AutoStop can be reconfigured to give a three (3)
inch rise as shown in Figure 4.
NOTE: If this configuration is used, the internal parts
will need to be rotated so that the actuator cable
still protrudes from the lower driver’s corner of the
AutoStop. See Disassembly / Assembly
instructions Page 5-8.
