his tow bar is equipped with a “quick-disconnect” (or, “QD”) system.
Before connecting the tow bar to the vehicle, first install the compo-
nents of the QD system to the mounting brackets.
Note: the quick-disconnect system is not used with ROADMASTER
‘MS’ or ‘MX’ series mounting brackets. If the towed vehicle has MS or
MX brackets, proceed to “Connecting the tow bar.” The quick-disconnect
system should be reserved, however, for subsequent vehicles which may
not have these brackets.
1.
First, attach the quick-disconnects (“QDs,” parts “A” and “B” in Figure
1) to the tow bar mounting brackets. Attach the QDs so that the vertical
pin on each is pointing up, as shown in Figure 1.
Attach part “A” on the passenger side, and part “B” on the driver side.
Use the supplied ½" x 1¾" bolts, the two safety plates (parts “C”), and the
flat washers, lock washers and nuts, as shown in Figure 1.
Note: both QDs have an extra hole — “D” in Figure 1 — for safety cable
attachment. Mount parts “A” and “B” so that the “D” holes are to the out-
side.
Do not tighten any of the bolts — leave them loose for now — they will
be tightened later.
Use all mounting hardware and both safety plates. If all supplied
materials are not used, the quick-disconnects, the quick-disconnect
bases or other components may vibrate loose, which may cause prop-
erty damage, personal injury or even death.
2.
Now, test-fit the crossbar — lower the crossbar (Figure 2) over the quick-
disconnects. The vertical pins at the top of both QDs should fit through
the top holes at the ends of the crossbar (Figure 2), and the vertical pins
at the bottom of the crossbar should fit through the lower holes on the
quick-disconnects (Figure 2).
3.
Both quick-disconnects must be positioned so that the crossbar is cen-
tered to the front of the vehicle — measure the distance between the side
of one QD and the side of the mounting bracket it is attached to. Then,
make certain there is an equal distance between the other QD and the
other mounting bracket.
The quick-disconnects must be centered on the mounting brackets.
If they are attached too far to the left or the right, the tow bar will
not be centered on the towed vehicle, which will cause excessive tire
wear and other consequential, non-warranty damage.
4.
Once the crossbar slides on and off easily, torque the four bolts to 75
ft./lbs.
Again, test-fit the crossbar over the QDs, to verify that the crossbar
slides on and off easily. If it does not, adjust the QDs again.
5.
Both linch pins
must
be inserted through the upper holes in the vertical
pins in parts “A” and “B,” as shown in Figure 2.
Both linch pins must be locked. The rings are spring-loaded — they must
be snapped over the pins, with the curved side of the linch pin touching
the ring, in order to keep the QD bases secure.
Towing vibrations will force the linch pins out unless they are proper-
ly locked in place over the vertical pins on both quick-disconnects.
Failure to properly install the linch pins will result in tow bar mal-
function, loss and damage to the vehicle and property, personal injury
or even death.
