NOTE

Less expansion will be encountered, when parachute is removed from housing, if allowed to stand for a longer period of time.

4. 5 Preparation of Parachute Can. Prepare pa:::achute can as follows.

4.5.1 Using existing holes in Clamp 2158783 as guides, and with Strap 2158780 straddling the groove in Can 2132250, match drill through, using

0.125 drill. Rivet clamp to can as shown on dwg 1330711.

4.5.3 Open parachute can and run nylon cord through the two holes in the hinged end of the can. Work insulation through holes until the holes are centered on the insulation.

4.5.4 Position nylon cord in the insulation as shown on dwg 1330711 and secure w~th a bowline knot and two cable straps.

~.6 Packing Pa:achute in Parachute Can. Pack parachute in parachute can as follows.

4.6.1 Loosen hand knob and swing rods free of pressure ring . Remove guide ring pressure ring assembly.

4. 6. 2 Re:•ove con;;>ressor center post by pulling straight up on the 0. SO inch cross bar.

4.6.3 Position exhaust valve. ex~ending from bottom of compressor housing, on pedescal assembly.

4.6.4 Lift free length of stati c line from top of compressed parachute and hang over the edge of the housing. Insure that the static line hangs over the edge of the housing on the same side of, and in line with, the vinyl loop.

4.6.5 Secure free end of nylon cord attached to parachute can in 4.4.4 to vent lines of parachute as shown on dwg 1330711 .

NOTE

Make sure that knot includes all of the vent lines and it allo~o'S the vent lines to center themselves when force is appl1ed to :i~es.
