Note: If the rated operating pressure cannot be
maintained with engine at full load speed
and rod (M) fully extended, turn regulator
adjustment screw (H) clockwise until
throttle arm (A) moves against governor
stop.
6.
Insure that pressure is maintained at rated
pressure, then turn regulator adjustment
screw (H) counterclockwise until throttle
arm (A) just begins to move.
Note: Turning regulator adjustment screw (H)
clockwise will raise pressure at full speed.
7.
Adjust jam nut (D) on throttle spring rod (E)
until distance “X” between spring mount (J)
and rod guide (K) is 2.88 in. (73 mm).
5.
Open and adjust service valve on outside of
the unit to obtain the rated operating pressure
on the discharge pressure gauge.
Normally, regulation requires no adjusting, but if prop-
er adjustment is lost, proceed as follows:
Before Starting Unit --
1.
At engine governor, (EG), check the position
of throttle arm (A) on governor shaft (B). This is
done by loosening nut (C) that clamps the
throttle arm (A) to the shaft (B). Rotate shaft
(B) counterclockwise as far as possible. Ro-
tate throttle arm until it is vertical. Tighten nut
(C).
8.
Close service valve (engine will slow to no
load or idle speed). Loosen jam nut (L) at air
cylinder (AC) shaft. Rotate air cylinder
shaft (M) to adjust speed to no load rpm. If
unable to obtain no load rpm, loosen nut (C)
and rotate throttle arm (A) as required.
Moving throttle arm (A) clockwise in-
creases idle speed. Tighten nut (C) and, if
necessary, finely adjust idle speed by rotat-
ing air cylinder shaft (M). Then tighten jam
nut (L).
2.
Adjust jam nut (D) on throttle spring rod (E) to
fully relieve tension on two compression
springs (F).
3.
Atop separator cover at pressure regulator
(PR) loosen locknut (G) counterclockwise.
Turn adjustment screw counterclockwise on
full turn.
After Starting Unit --
4.
Allow unit to warm up, then push “Service Air”
button on control panel.
9.
If necessary, repeat steps 5 and 6.
10.
At pressure regulator (PR) tighten lock nut
(G).
11.
Limit full load engine speed by adjusting the
collar (N) on the end of the throttle spring
rod (E).
12.
To obtain maximum CFM at any pressure
between 80 PSI (550 kPa) and the rated
operating pressure, turn adjustment screw
(H) of pressure regulator (PR) to obtain de-
sired discharge pressure at full load engine
speed. Always lock and protect pressure
setting of adjusting screw (H) with locknut
(G).
13.
Ensure unloader solenoid (US) acts to hold
pressure in inlet unloader (IU) after shut-
down. After start--up, a pressure switch will
open unloader solenoid (US).
