SYMPTOM: Character movements erratic. More than + 5% difference
in regulator gauge reading.
PROCEDURES: RESULTS:
!.Check the D.P.R. 40 and 80
p.s.i. gauges.
2. Test the air pressure at the
Distribution Manifold.
Should be 80 p.s.i. + 5%.
3. Manual override the D.P.R.
and test the air pressure at
the distribution Manifold.
Should be 40p.s.i. ~ 5%.
2-Q08
See pages 3-003 thru 3-005
and 3-014. If either or
both air regulators do not
hold a set and constant air
pressure. Replace the
regulator in question.
If the air pressure is
less than 80 p.s.i. + 5%.
Repair the D.P.R. Valve
See pages 3-005 & 3-014.
If D.P.R. valve does
shift, and air pressure
is steady and constant at
40 p.s.i. + 5%. See page
5-011. -
If D.P.R. valve does not
shift, repair the valve.
See pages 3-005 thru 3-014.
If the D.P.R. valve shifts
and the air pressure is
less than 40 p.s.i. + 5%.
Replace the Shuttle-cock.
See pages 3-005 & 3-014.
