The seat's centre of gravity can be adjusted by sliding the seat frame and combination seat height and seat tilt adjust-
ment module relative to the mobility base. Among other things, the permissible centre of gravity depends on:
•
Type and size of the mobility base (front-wheel drive FWD see Fig. 162, mid-wheel drive MWD see Fig. 163,
rear-wheel drive RWD see Fig. 164)
•
Seat depth

WARNING
Shifting the centre of gravity
Severe injuries due to the power wheelchair tipping over and falling
Only choose positions that are permissible for the new configuration. Contact Ottobock Customer Service for
more information. Have the serial number of the power wheelchair ready. It is used to determine the permissi-
ble positions.
Prior to initial use, test how changes in the centre of gravity affect the behaviour of the power wheelchair on
inclines, slopes, side hills or when crossing obstacles with the secure support of an attendant.
