If you choose not to check your battens for symmetry before each flight, you should, at a
minimum, check them once a month.
Aeros convention is that the red marked battens go in the left wing and green marked battens
go in the right wing. Battens are numbered from the center outwards, and the longest battens
for Profi TL are designated as the "No. 1" battens.
Install all cambered battens in the sail.
CAUTION:
INSERT BATTENS CAREFULLY, SO AS TO MINIMIZE STRESS AND WEAR ON
THE SAIL.
Never insert or remove battens with the cross tube tensioned (except for up to the last three on
each side) and never insert or remove battens with heavy wind pressure on the top of the sail
or in any condition which causes battens to slide with great resistance in their pockets.
Install the lever batten tips into the hem of the trailing edge (fig. 34 and fig. 35). At each batten,
make sure the opening in the underside of the trailing edge hem is spread to accept the tab on
the batten tip. Make sure the tab slides fully into the hem. Battens # 9, 10, 11 should be
tensioned after the sail is tensioned with the crossbar.

5.18. Check that the pull back (cross tube
tensioning) wires for twisted thimbles and
tangs. Take the shackle with one hand and
attach it to the hook placed on the keel
tube (fig. 36).
WARNING
An in-flight disengagement of this
attachment will cause a complete loss
of structural support of the wing and a
total loss of control. NEVER attach the
pull handle of the shackle to the hook,
even temporarily!
5.20. Install the bottom surface battens. The longest bottom surface batten is inboard batten.
Push the battens all the way into the pocket until the rear end is secure in the batten pocket.
The strings on the rear ends of the bottom surface battens are to facilitate removal of the
battens from the sail during breakdown (fig. 37).
