Installation Instructions
1.
Before beginning any work, clear the area and posi-
tion the 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
valve.
Figure 1 - Disconnect power and air sources.
2.
Verify the stored air pressure is zero by observing
the air pressure gauge on top of the tower (see photo).
Next with a 1 1/16-inch socket wrench, remove the
manifold with the gauge and safety valve.
Figure 2 - Remove manifold with 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.
Figure 3 - Install manifold, safety valve and barbed fitting.
4.
Next, remove nut on the bolt supporting the swing
arm pivot system. With the new 10 3/4-inches (273 mm)
long bolt push the old bolt out with the new bolt. Make
sure the small washer is on the head of the new bolt.
Figure 4 - Use new long bolt to push old bolt out.
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.
