Parts of the Air Cart
1. Connecting Extendable “D”
Handle. By extending the
handle upward and replacing
the pin to lock the handle in
place, the cart will not hit the
operator’s feet while moving to
the deployment area.
2. Stand-Off Bracket. The stand-
off bracket can be used to place
the cart in a horizontal position
on a slope. A pin locks the
bracket in place.
3. High-Pressure Manifold. This
manifold supplies the whole
system. A low-air alarm will
activate if the pressure drops
below 500 psi. It will also
continue to sound if the air
supply is below 500 psi.
*Blue handles are for high-
pressure inlets only. During
normal operation, they are to
remain closed.

4. Three-Way Diverter Valve. This
indicates which cylinder is
supplying air. The handle has
an arrow on top and indicates
which cylinder is supplying air.
5. Bleed Valves. These bleed
valves are used to vent any
remaining pressure from the
supply cylinder after the change
from one cylinder to the next.
These vents are important to
bleed off to prevent damage to
the O rings.
6. Supply Hoses. Supply air from
the bottle throughout the
system.

7. Pressure Regulator. Designed
to flow in excess of 1200 lpm. If
it were to fail, it would fail in the
open position. It also has a
high-pressure gauge.
8. Low-Pressure Manifold. The
low-pressure manifold is where
you hook up the air hose. The
manifold has a safety relief
valve that will relieve at 125 psi.
It also has a safety lock ring to
prevent accidental discon-
nection. The red arrow in the
photo points to a low-pressure
gauge.
9. Electronic Command Module.
This is a low-pressure warning
device. It has three lights:
green indicates it is armed and
in standby mode, red indicates
it is in alarm mode, and yellow
is the low-battery voltage alarm.
To turn off, bleed all air and
allow it to go into alarm mode.
Press and hold (black arrow)
this button down for five cycles
of the alarm and release.
