6.5 Adjustment of the Centre of Gravity (CoG)
The CoG can be adjusted in various positions between:
•
Very passive: wheels are in a rearwards position, the
chair is very stable and it´s difficult to lift the front
wheels to overcome obstacles.
•
Very active: wheels are in a forward position, the chair
is easier to maneuver, it´s easier to lift the front wheels,
however the chair can easily tip over to the rear
By moving the axle-plate (1) forwards (more active) or
rearwards (more passive) on the frame, the CoG can be
adjusted in 5 positions (Fig. 6.20).
To adjust CoG, proceed as follows:
Remove the rear-wheels. Loosen Allen bolt on top of the
axle-plate (2). Remove Allen bolt on the bottom of the
axle-plate (3) and finally remove the lid (4) including the
set-screw. You can now slide the axle-plate in the desired
position and re-assemble the lid (4) again. Make sure the
set-screw fits into one of the holes on the frame.
Assemble the lower Allen bolt (3) and tighten both Allen
bolts (2 and 3) to the specified torque.
WARNING!
Make sure to re-adjust wheel-locks and, if necessary, side
guards according to the new position of the wheels.
Failure to do so may result in user injury!
CAUTION!
Always make sure that the COG setting is the same on
both sides.
DANGER!
Familiarize with the altered balance of the chair! When
setting the CoG towards a more active position, the chair
will become more prone to tip rearwards which might
result in user injury. Be cautious and use anti-tips if
necessary.
