(6) Inspect sealing clamps (5, 6, and 7, fig. 3-7) for stripped threads and missing parts. e. Pressure Control (1) Inspect  pressure  control  for  broken  or missing dust plug and dust cap. (2) Inspect  pressure  control  for  cracked  body and loose or missing capscrews and nuts. (3) Report all deficiencies that cannot be cor- rected to the proper authority on Standard Form SF 368 (Quality Deficiency Report). 4-3. Preparing and Filling the Drum. Select a site near the source of supply which is level and firm as possible. Clear the site enough to permit the drums to be conveniently lined up for filling and to be rolled away after filling. a Drum Setup. NOTE Perform the daily preventive mainte- nance checks and services listed in table 3-1. (1) Remove the dust plug from the female coupling half on pressure control (fig. 4-2) and con- nect  discharge  hose  to  the  pressure  control. (2) Remove  the  dust  cap  from  the  main  coupl- ing half on the pressure control and connect hose assembly to the pressure control. (3) Remove  dust  plugs  from  the  openings  in the  coupler  valve  assembly  and  close  the  valve  by turning the handwheel clockwise. (4) Install  the  2  inch  (5.08  cm)  female  coupler of the coupler valve assembly on the check valve assembly  adapter. (5)  Install  the  main  coupler  of  the  hose assembly in the 1-1/2 inch (3.81 cm) female coupler valve  assembly. b. Fill Drum. Be certain the drum is secure to avoid slipping or rolling during filling opera- tion. Avoid spillage of product. If spillage occurs cover the area with dry soil to reduce its rate of vaporization. Avoid getting product on body or clothing. If clothing becomes saturated with product remove the clothing im- mediately and wash body with hot soapy water. Do not allow smoking within 100 feet (30.5 meters) of the filling area. Be certain a suitable fire extinguisher is present. (1) Disconnect coupler valve assembly from the check valve assembly adapter. (2) Turn  handwheel  counterclockwise  two turns  to  partially  open  the  valve. (3) Open the valve assembly at the source of product  supply, (4) Start  the  pump  assembly. (5)  Hold   coupler   valve   assembly   over   a suitable  container  for  catching  product. (6) Depress  and  hold  the  FILL  button  (fig.  2-2), until the product is dispensed from the coupler valve assembly, indicating all air is purged from system. (7) Turn handwheel clockwise until flow of product  from  coupler  valve  assembly  is  stopped. NOTE The pressure control will close when the flow of product is stopped at the coupler valve  assembly. (8) Install 2 inch (5.08 cm) female coupler of the   coupler   valve   assembly   on   check   valve assembly  adapter. (9) Turn  handwheel  counterclockwise  to  open the  valve. (10) Push  the  FILL  button  on  the  pressure  con- trol  and  allow  the  drum  to  fill. NOTE A slight flexing in the nose assembly means the pressure control is closed. (11) Close coupler valve assembly by turning handwheel  clockwise. (12) Disconnect  coupler  valve  assembly  from check valve assembly adapter. Install dust cap over  check  valve  assembly. 4-3
