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.
Cruiser-Feeling
Pleasantly damped and
smooth seat surface

directional stability

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.

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.
