C.O.G, Setup
To carry out COG adjustment, there are basically 2 different options.
The adjustment can be carried out straight on the axle adapter
(standard adapter only). When doing this, the crescent-shaped spacers
can be pushed from one side to the other. To make an adjustment in
larger steps, you must change the position of the axle bracket on the
frame.
NOTE:
• Changes to the centre of gravity may lead to an unstable wheelchair
which will tip over easily. In this case, anti-tip tubes are required.
• When determining the centre of gravity, it may be necessary to adjust
the castor angle.
Changing the position of the axle brackets on the frame
Using the quick-release axles, take the wheels out of the angle
adapter.
Undo both screws (1) and remove these completely. Fit the axle stem
in the desired position on the frame, put the screws back into the
perforated plate and then re-tighten the screws. When moving the axle
stem, also move the seat saddle on the frame, (change the axle stem
and the seat saddle). Make sure that the left and right sides are fitted
in the same positions. Use the specified torque of 8 Nm to tighten the
screws (Fig. 6.4.4 to Fig. 6.4.5).
Adjusting the centre of gravity with the standard axle adapter
Additional adjustments can be carried out straight on the axle adapter
(standard adapter only), and when doing this the crescent-shaped
spacers can be positioned accordingly. There are 3 positions (Fig.
6.4.6 to Fig. 6.4.8).
Using the quick-release axles (4), take the wheels out of the axle plug /
sleeve. Undo the Allen screws (1) with an Allen key. Remove the cover
(2) of the axle adapter and position the crescent-shaped spacers (3)
for the required centre of gravity. Put the cover back on.
To tighten the Allen screw (1) again, follow these two steps:
a) Tighten both Allen screws with a torque of 5 Nm.
b) Tighten both Allen screws again, with a torque of 8 Nm.
NOTE: If the camber adapter has been moved or twisted when adjust-
ing the seat height, the wheel alignment and camber must be checked
and adjusted if necessary (see the "Wheel alignment" section).
CAUTION!
• When replacing the Allen screws (1) on the axle adapter, you MUST
use Loctite™ 243 for thread locking.
