TM 55-1930-209-14&P-6 e. Startup winch as follows: NOTE Hydraulic  power  unit  can  also  be  started  by  pressing  START  button  on  hydraulic  unit  remote control switch located on stem weatherdeck bulkhead portside. (1) Push green START button on hydraulic power unit control panel or on hydraulic unit remote control switch (Figure 3-3).  If motor does not start, troubleshoot as given in paragraph 4-10.1. (2) If system has not been operated for several days, allow hydraulic oil to circulate at low pressure to remove entrapped air. Barge  1  -  Allow  pumps  to  run  with  winch  control  and  levelwind  control  levers  In  neutral position. Barges 2 and 3 - Allow pumps to run with disc brake control OFF and winch and levelwind control In neutral. (3) Check for oil leaks and tighten fittings if necessary. (4) Make sure charge pump pressure gauge on hydraulic power unit reads 250 psi. NOTE On Barge 1, levelwind is used during deployment and retrieval.    Cn Barges 2 and 3, levelwind Is allowed to freewheel during deployment. f. On Barges 2 and 3, turn valve SD5 ON (Figure 3-9). g. Release band brake as follows: (1) Close valve SD3 (Figure 3-8). (2) Obtain BAND BRAKE PUMP HANDLE from stowed position and insert in pump extension. CAUTION While pumping, do not exceed 4,000 psi as shown on BAND BRAKE PRESSURE GAUGE. (3) Pump until band brake piston comes out of the cylinder and there is a slight clearance between the ban brake lining and brake drum. (4) Remove pump handle and return to stowed position. h. Connect  washdown  hose  to  washdown  connection  on  deckhouse  top.    While  retrieving  discharge  hose,  wash mud and other foreign materials from hose. i. As hose is retrieved, remove marker buoys and lines and stow in ROWPU space aft stowage area. CAUTION As  each  layer  of  hose  comes  on  the  reel,  make  sure  transition  to  the  next  layer  is  smooth.    If necessary, operate LEVELWIND control lever to gently form the first coil of the next layer. j. Start retrieving hose by using winch control lever.  Operate LEVELWIND control lever to form first layer of hose on drum.  If necessary, operate LEVELWIND control lever to gently form the first coil of the second layer. Then operate lever as needed to form remaining layers.  On Barges 2 and 3, also operate disc brake lever when needed. k. When the discharge hose is completely retrieved, tie hose end cap to barge. I. Push red STOP button on hydraulic power unit to stop unit, or on hydraulic unit remote control switch. m. Open switchboard circuit breaker P12. 3-20
