Anti-G-Pocket
Simple to t
An Anti-G drogue chute can be fastened to
the green strap by a triangular Maillon, and
be stowed in its pocket.
Deployed either side
Two zips enable the Anti-G drogue chute
to be thrown from either side.
Fitting the blank
When an Anti-G drogue chute is not
carried, its pocket can be lled with the
foam blank, or used for other storage.
Windshield
Advantages
The Windshield reduces windchill and
upper body cooling.
It suppresses distracting and tiring
wind noise.
Fitting
Fasten the popper on one side, then
lead the windshield under the elastic
border and fasten the second popper.
Care
Never pack the harness with the winds-
hield mounted. Take it o rst.
Pack the Windshield in its cover and
store it at, e.g. between the folds of the
wing, so that it does not get bent.

With or Without Seatboard
You choose
The IMPRESS 4 can be own with or
without seatboard. When making the chan-
ge the harness settings do not need
substantial readjustment. If desired, mild
readjustment can be easily made after
ight. Without the seatboard the pilot is
supported a little lower in the harness.
Fitting and removing
The seatboard can be removed or replaced
from under the rear of the seat surface,
and secured by Velcro.

smooth seat surface

Speedbag & Speedsystem
Closing the Speedbag
a Close the front strap with both
Cobra-buckles.
b Close the green Speedbag-buckle.
c Close the Closure Remember System
(CRS) in 1-2-3 order.
d Fix the Cockpit to the front strap with
its buckle (optional).
e Close the small chest strap.
Getting into the Speedbag
1 Keep a forward-leaning attitude after
lifto, do not slide into harness yet.
2 After takeo look quickly down at the
Speedbag opening.
3 Put your right heel into the opening
and tension the speedbag.
4 Now put your left leg into the
Speedbag, then the right.
5 Stretch both legs out in front on the
footboard, the Speedbag closes by
itself.
Accelerating
1 Before ight set the speed lines to the
correct length, so that you can use the
whole range of the speed system.
2 Put one foot only into the rst rung of
the speed loop and leave the other foot
on the footboard.
3 Use the other foot when changing to
the second rung of the speed loop.
4 Make sure that your heels are not
positioned lower than the bottom of the
footboard, otherwise they could
damage the speedbag fabric.

Installing Reserves
Fitting one reserve
a A single reserve is connected to the
built-in connection line and can be
installed for left or right throw. Choose
the appropriate inner container.
b The partition in the middle of the
container can be moved by 4 cms
(Velcro) in either direction to accom-
modate reserve size.
c The empty side should be occupied by
the foam blank supplied and closed
with the dummy cables.
Fitting two reserves
d The second reserve connection line
(supplied) fastens to the shoulder area
with the Maillons provided.
e The two inner containers must occupy
their correct sides of the reserve
compartment. This arrangement must
not be reversed.
Certied reserve volumes
S size: 3 – 5.5 ltrs / M size: 3 – 6 ltrs /
L Size: 3 – 6.5 ltrs
Approximate formula: Volume (l) =
Reserve weight (kg) x 2.7
Compatibility test is essential
In every case the compatibility test carried
out by the pilot him/herself is the only way
to prove that the whole system will work
reliably.
Caution: Installation of the reserve(s)
must be carried out by a qualied
person.
Caution: Only use the original reser-
ve handle and its attached inner
container.
Caution: Each harness size has its
own inner container size, marked on
its handle.

«Installing Reserves»

General Information
The procedure is the same, with or
without seatboard.
Most pilots with a typical upper body to
leg length ratio require only small varia-
tions of the basic harness settings.
Tune your adjustments in 2-cm (max)
steps, bearing in mind the two funda-
mentals: comfort (no pressure points)
and good aerodynamics (undersurface
of speedbag horizontal in ight).
Repeat the following steps until you are
happy with the results, ne tuning after
the rst few ights if desired.
Preparation and basic settings
Install your reserve before adjusting
harness settings.
Pack your rucksack in the back pocket.
Set all straps to their basic settings (As
Delivered).
Close harness and Speedbag and hang
yourself (in the harness) up in a harness
hanger.
Ask an observer to assess the resulting
inight attitude.
Harness Adjustment
Video Tutorial
«Gurtzeug einstellen»

1. Position your body on the seatshell
a If your centre of gravity is too far back
(feet in the air) push it forward by
pulling in the lower back straps – or
vice versa.
b Then adjust the middle back straps (in
or out) until your lower back (lumbar
spine) is comfortably supported.
A comfortably supported back without
the feeling of straps under the armpits is
a good indication of an ideal position in
the seat shell.
2. Setting the upper body recline angle
c This angle is set by the upper back
straps.
d Now you should adjust the shoulder
straps so that they lie loosely on the
shoulders.

3. Aligning the Speedbag
e To adjust a speedbag line loosen its
anchor hitch and move the position of
the ball.
f Adjust speedbag length with the lower
lines so that your legs apply light
pressure when stretched.
g Adjust Speedbag angle by the diagonal
lines. Speedbag lower surface should
y as horizontal as possible.
h Now adjust the angle of the footboard
to suit your feet (toes) with the upper
speedbag lines.
4. Seatboard/Seatshell setting
i The thigh straps are correctly set when
you feel comfortable thigh support
from seatboard or seatshell.
5. Adjusting Front strap
Set the front strap as you wish. It can be
adjusted in ight.
Use of the small chest strap is optional.
