NOTE

Air pressure gauge on instrument panel

has a maximum pressure reading of 120

psi. If old governor has been replaced

with new governor, air pressure may

exceed maximum pressure reading on

instrument panel gauge.

5. Compare test gauge (8)

reading with gauge on

instrument panel.

1. If low or no air pressure is

indicated on test gauge (8), check

air horn supply line (7) for

restrictions or leaks. Repair or

replace damaged compressed air

lines (TM 9-243).
