(Duncan EazAligner & TowMatic II Self-Aligning Tow Bars)
INSTALLATION (DUNCAN SELF-ALIGNING TOW BARS)
1. Refer to page 6 while installing the
KarGard. Mount the tow bar to the towed
vehicle's baseplate, as if to tow it. Support the
coupler on blocks or a stand at approximately
the same height as your hitch ball.
IMPORTANT: DO NOT hook the tow bar to
the towing vehicle. During installation, bolts
will be removed and the hook up will make it
difficult to remove bolts.
2. Remove the tow bar from the quick attach
receiver brackets. Remove the inside bolt
holding the (PS) receiver bracket, and the
outside bolt holding the (DS) receiver bracket
to the cross angle. Install the angle brackets
behind the cross angle pointing towards the
towed vehicle.
NOTE: Use the existing bolts just removed
but be certain to reverse them so the bolt
head is on the back side against the new
angle bracket and do not use a flat washer
under the bolt head. This will allow clearance
for the 1/2" bolt installed in the next step.
3. Using the 1/2 x 1 1/2 bolts and Nylon nuts
provided, attach the tower bases to the angle
brackets just installed. Orient as shown using
the hole closest to the tower base cup. Snug
the bolts, but do not tighten at this time.
4. Install your tow bar onto the quick attach
brackets and fold it to the stored position to be
sure that the tower bases will not interfere,
adjust accordingly. The tower bases will work
in a wide variety of locations.
5. Set the towers into the tower bases (plastic
plugs up) and install the spring lock pins.
6. Assemble the tower clamps to the upper and
lower "L" brackets so you have four bracket
assemblies, an upper and lower right and an
upper and lower left. Be sure to orient the
clamps and "L" brackets as shown on page 4.
Slide a rubber washer over each of the four
dowel pins on the "L" brackets.
7. Slide the four bracket assemblies onto the
towers. Snug to keep in place but do not
tighten at this time.
NOTE: "L" brackets with short pins with a hole
through them are upper brackets.
8. Remove the locking rod and unfold the
KarGard. Install the locking rod to keep the
KarGard straight. Set the KarGard across the
tow bar assembly with the driver side "Hold up
pin" of the tow bar inserted through the center
hole in the bottom aluminum angle. Slide the
upper brackets up until the dowel pins fit
through a hole in the upper aluminum angle of
the KarGard, and install the two hair pins.
IMPORTANT: Use any holes, but be sure to
keep the KarGard centered in front of the
towed vehicle.
Snug the upper brackets, but do not tighten at
this time. Slide the lower brackets up until the
dowel pins fit through the same holes in the
lower aluminum angles as used in the upper
angles. Snug the lower brackets, but do not
tighten at this time.
9. Determine if you need to lower the KarGard to
provide maximum protection of your towed
vehicle lower valence. If you need to lower it,
follow the instructions printed on the template
supplied with the KarGard.
10. Once openings are cut, (optional) reinstall the
KarGard onto the tow bar hold up pin and
KarGard dowel pins (bottom first) and install
the hair pins. Slide all mounting brackets and
the KarGard down as needed and tighten the
mounting brackets.
NOTE: Passenger side of KarGard will rest
on the quick attach and the driver side will be
slightly raised to keep the KarGard parallel
with the tow bar and the ground.
11. Tighten all bolts firmly. Make it a habit to
check all fasteners occasionally for tightness.
The manufacturer accepts no responsibility
for any damage caused to the KarGard or to
the towed or towing vehicle from improper
installation of this product.
Be sure to read page 1 where you will
find important information about your
KarGard, as well as installation and
storage instructions for everyday use.
