Here you will find instructions on some of the steps involved in operating the paraglider.
Acting upon notices of problems encountered in speed-system operation in some of our PPG canopies, we’ve prepared a bulletin on this matter, containing assembly instruction for the covers positioning the pulleys.
Trimmer buckle and strap replacement
Sometimes after long use the trimmers cease to operate correctly, i.e. they slide away of their intended position. In some cases it is just a matter of accumulated grease on the tapes, so first you can try to clean them with kleenex for example.
Currently all these canopies are produced with some “steps” sewn on the trimmer tapes which stop the sliding buckles, thus minimising possible asymmetry.
If the trimmer tapes are worn out and tend to keep sliding away, they should be replaced. For this we prepared a dedicated replacement set, including:
two new trimmer buckles with removable cross-bar for easy exchange
two new trimmer tapes with “steps”
some glue to prevent the screwes from getting loose.
Below you can see an instructional video on replacing the buckles. To put it short: the old buckles are sawed in half (they have a fixed bar), removed and replaced with new ones.
What to do with releasing trimmers?
We have received signals concerning the independent trimmer releases. We noticed that there could be two reasons for this:
Worn, hard-used trimmer tapes and/or buckles – self-release may then happen in flight, especially under heavy loads. The trimmer is most often released to the nearest bolt stitching, which is made about every 3 cm. When this is occurring repeatedly, such a tape should be replaced by yourself or at the workshop, depending on the wing you have (some paragliders, such as WARP, DriftAir or Cabrio should be delivered to us, in other wings it is possible to replace just the trimmer tape or the whole replacement kit including a new buckle).
Accidental release, sometimes complete, during take-off. The problem here may be the starting technique, which causes pressing the forearm on the plate extending the trimmer buckle lever. In this case, you should either change the starting technique or unrivet the plate extending the trimmer buckle lever. However, be aware that the lack of this plate can later make it more difficult to release the trimmer (you need more of force for this).The change of the starting technique consists in careful arranging the risers on your arms so that the release trigger stays on top (not pressed against the shoulder):
Theoretically, it may also happen that the buckle itself is faulty, but at the moment we run four-stage quality checks during risers production, so this shouldn’t be occurring.
How steering lines should be attached to steering toggles
The pictures show the way steering lines should be attached to steering toggles. Such a knot cannot go untied – on the contrary, every pull on the steering line (i.e. every steering input) strengthens it.
Showed knot is used by our assemblers on each wing leaving Dudek Paragliders, and in case of any alterations (mainly steering lines length adjustment) please take care to have it fixed exactly the same way afterwards.
Speed line replacement
HOW TO REPLACE A SPEED-SYSTEM LINE WITH A NEW ONE (THICK)
Sometimes it is necessary to exchange speed-system line for a new one. You can do it yourself, as shown here: english version.pdf
HOW TO REPLACE SPEED-SYSTEM LINE OF OLDER TYPE (THIN)
When a line of older type (thin) breaks, attaching hooks to the new one can be troublesome. Thanks to Clive Bunce there is some guidance here HERE
