COG, (Centre of Gravity), Setting
To carry out COG adjustment, there are basically 2 different options.
Adjustment can be carried out directly on the axle bracket (Standard
adapter only ) by shifting the crescent-shaped spacers from one side to
the other. To make an adjustment in larger steps, you must change the
position of the axle-stem on the frame.
NOTE:
• COG Adjustments may lead to an unstable wheelchair, likely to tip.
This requires the use of anti-tip tubes.
• An adjustment to the castor angle may be necessary when adjusting
the COG.
Changing the position of the axle stem
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 given torque of 8 Nm (Fig.6.4.4 to
Fig.6.4.5).
COG setting on the standard axle bracket
Adjustment can be carried out directly on the axle bracket (standard
axle bracket only) by shifting the crescent-shaped spacers from one
side to the other. 3 Positions are possible (Fig.6.4.6 to Fig.6.4.8).
Using the quick-release axles, take the wheels out of the axle adapter
(4). Release the Allen screws (1) with an Allen key. Take the lid (2) of
the axle bracket off and arrange the crescent-shaped spacers (3)
according to your desired COG. Put the lid back on.
Re-tighten the Allen screws (1), using a two-stage process:
a) Tighten both Allen screws to a torque of 5 Nm.
b) Tighten both Allen screws for a second time to a torque of 8 Nm.
NOTE: In case the axle adapter was moved or removed whilst
adjusting the COG, wheel alignment and wheelbase width needs to
be checked and if necessary, adjusted (please refer to the "Wheel
Alignment" section).
CAUTION!
• Loctite™ 243 thread locker MUST be used for re-mounting the Allen
screws (1) on the axle-adapter.
