WARNING
DO NOT let go of static reel cable when re-
winding until the ball stop Is firmly touching
the reel. Failure to follow this warning may
cause injury to personnel.
(6) Static Reel (M969 and M969A1).
This static
reel in the piping control assembly (para 2-11) is used
when two vehicles are being serviced at the same time.
The static ground cable is pulled from the static reel and
attached both to the unit being serviced and to a grounding
plug, stud, or clamp. The reel has an automatic locking
device which engages when the cable is extended to the
desired length and releases when the cable is pulled out
again. The reel is spring-loaded to rewind automatically.
d.
Bulk Fuel Servicing Hoses.
Whenever bulk fuel
hose is required, remove the necessary lengths from the
hose troughs and couple together as required.
e.
Nozzles.
Make sure hoses are installed with
correct nozzles for the operation intended. For M969 and
M969A1, contact unit maintenance to install nozzles.
f. Emergency Valve Operation.
The emergency valve
(fig. 2-16) controls the tank outlet. The emergency valve
and its related vapor vent are mechanically operated by a
lever, operator A, in the piping control assembly (figs. 2-11
and 2-12). Engaging the lever opens the emergency valve
to permit fuel flow to/from the tank sump. At the same
time, the vapor vent at the top of the tank opens to relieve
pressure/vacuum during loading/unloading.
(1)
The emergency valve must be open for all
loading/unloading operations except top loading.
(2)
In an emergency, close the emergency valve
by disengaging operator A (roadside of semitrailer) or by
pulling emergency valve shut-off (fig. 2-17) (on opposite
side).
