1. Before beginning any work, clear the area and
position the machine for easy access. Disconnect all
power sources, both air and electricity inputs. Allow
any stored air in the reservoir to escape by depress-
ing the inflate valve.
2. Verify the stored air pressure is zero by observ-
ing the air pressure gauge on top of the tower. (see
photo). Next with a 11/16-inch socket wrench remove
the manifold with the gauge and safety valve.
3. Next install the included manifold with the
gauge and safety valve plus a barbed hose fitting.
Tighten until the barbed fitting is located as shown in
photo.
4. Next, remove the nut on the bolt supporting the
swing arm pivot system. With the new long bolt
(103/4-inches) push the old bolt out with the new bolt.
Make sure the small washer is on the head of the
new bolt.

5. Next, install the large plated spacer, the swing
arm (note position of the decal) with pivot pin spacer,
and the lock nut. Next, using large wrenches, tighten
the assembly to 240 ft. pounds torque (very tight).
Even though the bolt is very tight, the assembly
should rotate easy.
6. Next, locate arm with cylinder, install seven inch
bolt with head through the bottom side, slide pivot
pin over bolt and attach nut with only one turn.
7. Slide the cylinder arm through the swing arm
bushing, hold in position, remove nut and place
washer over bolt threads and assemble nut to bolt.
8. Next using large wrenches, tighten the assem-
bly to 240 ft. pound torque (very tight). Again, even
though the bolt is very tight, the assembly should be
free to rotate.

9. Next, unwrap the red hose from valve, guide
through hose clamps; and, with the hose pushed
over the barbed fitting, tighten the screw type hose
clamp.
Next, reconnect the air pressure source and check
for leaks. Cycle the cylinder on the Robo-Arm™ sev-
eral times to understand function.
10. For installing bead roller assist tool, attach the
rectangular tube in the kit to the “Bead Loosener
Arm”. Use the existing hole in the bead loosener
arm. Position the tube at a slight angle and tighten.
11. Next will be the installation of the duckhead
bracket. Start by removing the bolt in the bottom of
the vertical slide bar. This bolt is very tight; use cau-
tion when loosening.
12. Next install the bracket to the vertical slide
using the hex bolt; discard the washer. Note that the
metal duckhead is shown; the plastic duckhead can
be substituted for the metal duckhead.
