15pt
JAZZ has 3 risers.
The A riser has a red cover to easy identification.
There is another line with red mailon.
There is A’ and is for the big ears.
They come in different diameters of Kevlar and Dyneema with sheathed cover. They must
to be inspected every 100 hours maximum.
In case of Brake lines, it was cut a little longer, so every pilot can adjust it according to his
personal taste.
But you must always leave 10cm before the brakes line starts acting in order to avoid trailing
edge deformation when the wing is fully accelerated. In case the brake handle comes loose
during flight or any brake lines is cut you can use the C riser softly for directional control
instead of brake line.

5. Adjustable Brake Pulley Position
The brake line pulley position can be adjusted according to pilot preference to suite the
power unit’s hang points height. There are 2 settings: Upper and Lower. The upper setting
(as set by the factory) is for low hang point motors whilst the lower setting is for units with
higher hang points.
If you use the lower pulley, you must lengthen the brake lines accordingly. Moving to the
lower pulleys requires the addition of 5cm to the overall brake line length (measured from
the mark on the brake line).
To change the pulley position, remove the brake line from the pulley by taking off the brake
handle. Re-route the brake line through the other pulley before attaching the brake handle
at the new adjusted length.
