TM5-4210-229-14&P 2-16.  OPERATION OF HYDRAULIC RESCUE TOOL. NOTE If the hoses are reversed,  the tool will operate in reverse. a.     Attach the 16 foot hose assembly to the power unit.  The hose swivel end marked in red is the pressurized side and is connected to the dump valve (t3 figure 2-9) outlet also marked in red.  Tighten with a 5/8 inch wrench. b. Connect the hydraulic rescue tool hoses to the hose assembly from the power unit.  The locking collar must snap  fully forward or the couplings are not locked and will disconnect under pressure. c. The handle of the reservoir mounted dump valve (3,  figure 2-9)  points  in  the  direction  of  flow.    The  handle forward points the flow out through the hose,  facing the rear points the flow back into the reservoir. d. To start the power unit,  open the fuel shut-off control (4,  figure 2-9).  Position the dump valve lever (3) in the dump position.  Put the throttle control (2) in the slow position,  and pull the starter handle (l) with a short pull to start the engine. e. Turn the dump valve lever (3,  figure 2-9) forward to point out in the direction of flow. f. Move the throttle control (2,  figure 2-9) to accelerate power unit to desired operating speed. NOTE If the tool works in reverse,  check the hose connections for proper installation. g. The operating levers (l,  figure 2-9) are mounted on the hydraulic rescue tool.  If valve is on the right side of the tool housing,  pushing the lever (l) with the thumb will close the rescue tool.  Pulling the lever (l) forward will open the rescue tool. h. Cycle the hydraulic rescue tool through at least two complete cycles.  One cycle is defined as closed to fully open and back to the closed position. i. To stop the power unit,  move the throttle control (2,  figure 2-9) to the stop position. NOTE An aircraft rescue tool kit is supplied for additional aid in aircraft and ve- hicle rescue procedures. j. The following are basic set-ups using the hydraulic rescue tool and attachments. (1)  Spreading procedures. a.Opening  Door.    Insert  the  rescue  tool  into  the  window  firmly  seating  the  lower  jaw  on  the  top  of  the  window opening.  The upper jaw should be on the top of the window frame and the edge of the car roof.  Opening the arms of the rescue tool will push the top of the door down and out away from the B pillar creating an opening between the door and the door frame.  Close the rescue tool arms inserting the tips of the jaws into the opening between  the  door  and  door  frame.    Open  the  tool.    Adjust  the  tool  to  get  a  firm  grip  and  open  the  arms. Re-adjust the jaw location if the metal tears.  Break the safety door latch and open the door. b. Removing Door. 1. Swing door open and insert the jaws of the closed tool into the hinge side between the door and the frame. Make sure the jaws are firmly seated.  Open the arms of the tool,  break the hinges and remove the door. Break the top hinge first to be sure door rotates down and away from passengers and operator. 2-66
