  • Page 9: Installing A Reserve

    Steerable reserves The LIGHTNESS 4 can also be used with a steerable reserve. Connection to the harness should be made with two maillons of minimum strength of 2,400 daN, direct to the coloured marked suspension points under the covers on the shoulder straps.
  • Page 10 Only use the original reserve handle and its attached inner container. Packing the reserve parachute in the inner container Always pack your reserve parachute to fit the shape and size of the supplied LIGHTNESS 4 inner container. Place the rescue lines in the back in the direction of flight/throw.
  • Page 11 Close inner container Close the five-flap inner container in the order of the numbers on each flap 1-3. Secure the last flap 3 with a line loop that should be about 5 to 6 cm long (about 3 fingers wide). Now check the pull of the elastic and shorten or lengthen it as needed.
  • Page 12 5.2.2. Connecting the reserve to the harness By looping Based on extensive testing, ADVANCE harnesses can also be looped with Companion reserves, provided basic precautions such as center looping and maximum tightening of the straps are observed. We cannot make any binding statement about the strength of ADVANCE harnesses in combination with other reserve systems.
  • Page 13 With a Maillon Rapide Connect the sewn bridles of the LIGHTNESS 4 and the bridle of your rescue parachute with a Maillon Rapide of at least 2,400 daN strength. Secure the straps in the Maillon with a rubber ring or neoprene tape, to prevent slipping and thus transverse loading of the Maillon in the event of a reserve deployment.
  • Page 14 2. Neoprene cover Warning Do not use tape instead of the rubber ring to fix the Maillon Rapide! When looping a COMPANION reserve with the LIGHTNESS 4, the V-line Neoprene Cover Info must be pulled over the connection. Warning Never attach the inner container to the reserve parachute! 5.2.3.
  • Page 15 When installing the reserve, always place the bridle in the reserve compartment first and then the inner container. Red dot to red dot. The connection to the reserve handle must be without twists. If a reserve parachute does not fit in the inner container after repacking, it must be Warning refolded to the shape of the inner container.

  • Page 20: Adjusting The Harness

    5.3. Adjusting the harness General Information Take some time to adjust your LIGHTNESS 4 and always keep these two criteria in mind: comfort (no pressure points) and aerodynamics (speedbag base horizontal). The majority of pilots with a normal upper body/leg-length ratio will not be far from the basic settings.

  • Page 22 Install the reserve before adjusting the harness. Load the back compartment with your equipment. Set all straps to the basic settings (as delivered). Close the harness and speedbag and hang this arrangement on a simulator (harness hanger). Ask a bystander to assess your harness position (flying attitude). Basic settings 1.
  • Page 23 Body (center of gravity) position in the seat shell 1. A comfortably supported back is a good indication of an ideal body position in the seat shell. An indication of the correct size and position in the harness is the distance between the edge of the harness and the shirt collar. 2.
  • Page 24 Adjusting upper body angle 4. Now you can also adjust the shoulder straps so that they lie "lose" on your shoulders. Make sure you always have some tension on the shoulder straps, this helps to stretch the Info seat shell. Aligning the speedbag 5.

  • Page 27 The easiest way to do this is to hang up the harness for adjustment. 1. Connect the speed lines of the LIGHTNESS 4 to your paraglider using Brummel hooks or anchor hitches. 2. Position the knots on the speed lines inside the speedbag to the correct position and pull the anchor hitches to the same position each side.

  • Page 28: Preparation For Flight

    The speed system is correctly set when you can reach the full range of the acceleration Info system with the second rung of the speed loop.  Make absolutely sure that the speed lines are not adjusted so short that the wing would Info be permanently accelerated in normal flight.

  • Page 29: Pack The Back Compartment

    6.3. Pack the back compartment Careful packing of the back compartment contributes significantly to flight comfort. Hard objects will be felt through the back wall or harness shell and can affect your comfort. Pack the paraglider COMPRESSBAG first at the bottom of the back compartment. Then roll the LIGHTPACK DLS into a long, thin shape and push it into the back compartment.

  • Page 34: Clipping In The Paraglider

    6.5. Clipping in the paraglider The EASY CONNECT SYSTEM with its coloured markings on the LIGHTNESS 4's main support loops makes clipping in an ADVANCE wing especially straightforward. The pilot only has to check that the red and blue lines on the glider risers match the same colours on the LIGHTNESS 4 support points.

  • Page 35: Use In Practice

    Symmetrical acceleration The two rungs of the LIGHTNESS 4 speed loop are reinforced in the middle. This not only increases comfort when pushing the accelerator, but also makes it easier to center the feet in the accelerator and thus accelerate symmetrically.

  • Page 36: Packing The Equipment

    The LIGHTNESS 4 is easy to pack due to its dimensions. Fold the cockpit and put the speedbag including the foot plate into the seat. Then fold the harness once and fold the rear spoiler. Turn the now compact package over once as shown in the picture.
  • Page 37 Prepare your rucksack and your glider as shown in the picture. Put your glider in the backpack and slide it all the way down under the rucksack flap. Then place the folded harness on top of the glider with the protector facing upwards and pull the flap of the rucksack over the glider and the harness.

    Warning Always remove the Windshield before packing. When closing the rucksack, always make sure the zipper runs smoothly. It should never be Info under lateral tension when pulling the zipper. 7.5. Emergencies 7.5.1. Reserve Throwing the reserve Use the correct technique to release and throw the reserve. This is a pull then throw to the side. Do not pull straight up.
  • Page 39 Reserve landing in strong wind In a strong surface wind there’s a risk that the pilot, attached at the shoulders, will be dragged over the ground by the reserve and paraglider. Options for dealing with this are distinctly limited. This is why it is important that all buckles except the front strap should be open before touchdown.

  • Page 40: Maintenance & Care

    Maintenance and care of the harness after a water landing After contact with water, all protectors and the comfort foam should be removed from the LIGHTNESS 4. See chapter "Installing/removing components". Everything should then be allowed to dry in a shaded place outside, or carefully laid out in a dry room –...

  • Page 41: Maintenance

    Ultraviolet light, heat, humidity, sea water, aggressive cleaning agents, unsuitable storing and physical abuse (  dragging across the ground ) speed up the ageing process. Hint Always store your harness uncompressed in a dry and dark place. Allow a wet or damp harness to dry by leaving it completely unpacked at room Hint temperature, or outside in the shade.
  • Page 42 Like any flying device, every harness should be routinely inspected by its pilot so that any damage to seams, straps etc. can be quickly detected and repaired. . Especially after a tree landing or a hard emergency landing on the protector, the harness must be visually inspected in detail for damage, before it flies again.. Do not make any modifications to your harness and never fly with a harness whose straps Warning are damaged in any way.
  • Page 43 The foam protector does not require any special care, but it should definitely be inspected for possible damage after an impact. In case of damage to the outer shell/s, the protector must be replaced. 8.3. Inspection Inspect your harness regularly for damage and have it thoroughly visually inspected by a professional every 24 months.
  • Page 44 ( e.g. inadequate maintenance, unsuitable storage, overloading, exposure to extreme temperatures, etc. ) are expressly excluded. The same applies to damage attributable to an accident or normal wear and tear. 10. TECHNICAL DATA 10.1. Data LIGHTNESS 4 Pilot height 155-172 165-183 178-200...
