TEST OR INSPECTION
If air lines are under pressure when they are disconnected, they can whip around
and cause injury to personnel. Caution should be exercised when disconnecting
air line fittings.
Air pressure is checked by disconnecting air lines at bumper turret junction box and
observing air pressure escaping from air line. System air pressure may drop below 85 psi
(586 kPa) during this procedure.
Release bumper turret control discharge switch (WP 0004). Remove bumper turret
junction box cover (WP 0572). Disconnect air line at bumper turret junction box. Check
if air pressure is present at bumper turret junction box.
If there is no air pressure, replace air line to bumper turret junction
box (WP 0567).
