TM 55-1930-209-14&P-6 f. Close (ON) switchboard hose reel circuit breaker P12 (Figure 3-10) supplying power to hydraulic unit, electrical motor, and controls. NOTE Hydraulic  power  unit  can  also  be  started  by  pressing  START  push  button  on  hydraulic  unit remote START/STOP switch located on deckhouse aft bulkhead portside. g. Push green START button on hydraulic power unit control panel located in void 5 (Figure 3-3 ).  If motor does not start, troubleshoot as given in paragraph 4-4.1. h. If initial.  startup, check pump rotation as shown on identification plate. i. If initial startup, or if system has not been operated for several days: Barge 1 - Allow pumps to run with winch hose control and levelwind control levers in neutral position for not less than 5 minutes.  This allows hydraulic oil to circulate at low pressure to remove entrapped air. Barges 2 and 3 - Allow pumps to run with disc brake control in OFF position and winch hose and levelwind controls in neutral position for not less than 5 minutes. j. Check for oil leaks and tighten fittings if necessary. k. Make sure charge pressure gauge (Barge 1 - Figure 3-4; Barges 2 and 3 - Figure 3-5) on hydraulic power unit reads 250 psi.  This is the minimum pressure needed for proper stroke control and make-up flow for winch circuit. I. Check  bias  settings  for  piston  pump  stroke  control.    With  winch  control  lever  in  neutral  position  on  Barge  1 (Figure 3-1) or OFF position on Barge 2 and 3 (Figure 3-2), compare readings between piston pump low pressure gauge  and  high  pressure  gauge  on  hydraulic  power  unit  (Figure  3-4).    These  gauges  indicate  pressure  on  two sides  of  winch  circuit.    If  the  two  readings  differ,  bias  should  be  zeroed  by  adjusting  zero  adjustment  screen (socket-head screw) on end of stroke control on piston pump.  This ensures that pump is fully destroked when winch hose control lever is in neutral position. m. If winch drum is secured, release winch drum tiedown. 3-3.1.4 Deployment of messenger (tow) line a. Make sure hose reel is installed and held in place by pins on each side to workboat. b. Using workboat, carry end of messenger line to shore. c. Unwind  messenger  line  by  turning  handcrank  on  starboard  side  of  winch  and  attach  messenger  line  to  shore winch.  Leave enough slack so that workboat can back off from shore before line is taut. d. Deploy line from workboat reel using winch handcrank while moving toward barge. e. Attach messenger line bitter end to discharge hose pulling head assembly with shackle and shackle pin.  Make sure shackle pin has been secured with wire or cotter pin to prevent loss during deployment to shore. 3-13
