WARNING
The overall performance of the wheelchair WILL
be affected by the front wheel mounting posi-
tion. The following charts show the mounting po-
sition of the motors for each seat width and depth
depending on the factory setting or user's weight.
If the mounting position that corresponds to the
user's weight is different than the factory setting,
the motors MUST BE repositioned to maintain
proper stability and controllability BEFORE using
the wheelchair. Otherwise injury or damage can
occur.
Periodically review the following charts to make
sure the motor mounting position still corresponds
to the user's weight to maintain the proper stabil-
ity and controllability.

ONLY - NEVER reposition the motors. Reposi-
tioning the motors forward WILL reduce the con-
trollability of the wheelchair. This procedure MUST
be performed by an Invacare Dealer.
NOTE: If motors are repositioned, the front riggings may
need to be repositioned. Refer to ADJUSTING/REPLAC-
ING TELESCOPING FRONT RIGGING SUPPORT in
