INSPECTION

1.

INSPECT INTAKE AIR CONTROL VALVE

(a)

With 53.3 kPa (400 mmHg, 15.75 in.Hg) of vacuum ap-
plied to the actuator, check that the actuator rod moves.

If operation is not as specified, turn the adjusting screw.
(b)

1 minute after applying the vacuum in (a), check that the
actuator rod does not return.

2.

INSPECT VACUUM TANK

(a)

Check that air flows from ports A to B.

(b)

Check that air does not flow ports B to A.

(c)

Plug port B with your finger, and apply 53.3 kPa (400
mmHg, 15.75 in.Hg) of vacuum to port A, and check that
there is no change in vacuum after 1 minute.

If operation is not as specified, replace the vacuum tank.
