COATS RoboRoller™ Assembly • 3
1. Before beginning any work, clear the area and
position machine for easy access. Disconnect all
power sources, both air and electricity inputs. Allow
any stored air in the reservoir to escape by depressing
the inflate pedal.
2. Verify the stored air pressure is zero by observing
the air pressure gauge on top of the tower.
3. Install RoboRoller arm assembly onto tower arm
pivot system bracket. Place a washer (11) on the head
of the 10-3/4 inch long bolt (10). Position RoboRoller
arm assembly (9) with pivot pin (8) spacer on the pivot
bracket, hold assembly and push long bolt with washer
through the top side of bracket. Next, place a washer
(11) and the lock nut (13) on the long bolt. Place the
trim strip (12) on the pivot bracket.
Note: Be sure to apply grease to the pivot pin.
4. 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.
5. Locate the two pieces of plasitc tubing (14); con-
nect each from the valve to the cylinder, respectively
(as shown in diagram).
Push one end of the 6-inch tubing into valve’s top self-
connect fitting; then route and push other end into
cylinder’s bottom self-connect fitting. Next, push one
end of the 27-inch tubing into valve’s bottom self-con-
nect fitting; then route and push other end into cylin-
der’s top self-connect fitting.
6. Connect the rubber hose (16) from the arm valve
to the air manifold. Before routing hose, remove tower
auxillary cover and the chassis side panel. Refer to the
diagrams on this page.
First push hose end over arm valve’s barbed fitting
(see back of arm view) and tighten the screw type
hose clamp (17). Then guide hose through clamp, on
arm; route around tower and down behind the vertical
slide plate tower bracket. Now, continue to guide the
hose into hole on tower support and through hole into
chassis.
Remove the plug from air manifold and replace with
straight fitting (15). Push hose end over straight fitting
and tighten the screw type hose clamp (17). Replace
tower auxillary cover and chassis side panel.
7. Next, reconnect the air pressure source and check
for leaks. Cycle the cylinder on the RoboRoller™ sev-
eral times to understand function.
