ADJUSTING WEIGHT DISTRIBUTION (FIGURE 10)
NOTE: Seat mount plates and seat support brackets allow the seat frame to be repositioned
along the base frame. The range is determined by position of the seat stop screws. The front seat
stop screw is positioned at 4-inches and the rear seat stop screw is positioned at 10-inches. Both
seat stop screw positions are measured from the front of the base frame.
NOTE: The position of the seat support brackets is factory set at 7-inches, this measured from
the front of the base frame to the front of the seat support bracket. This will put about 70% of
the total weight of the chair and user over the large wheels. However, this setting may not be
the most desirable in terms of maneuverability, front rigging clearance and comfort for the user.
ADJUSTMENT OPTIONS
NOTE: This section will provide the user with some knowledge of what to expect if the
following adjustments are made.
1. Moving the seat forward.
Advantage: This adjustment allows more clearance for front riggings and a more
stable “feel” for the user.
Disadvantage: More weight is put on front casters and makes turning more difficult.
NOTE: This option can also be accomplished by moving the motor backward on the suspension
arm. Refer to REPOSITIONING THE MOTOR in this section of the manual.
2. Moving the seat rearward.
Advantage: Makes turning easier and provide better traction for the large wheels.
Disadvantage: This adjustment, however, allows less clearance for front riggings and
the user will experience more engagement of the anti-tippers.
NOTE: This option can also be accomplished by moving the motor forward on the suspension
arm. Refer to REPOSITIONING THE MOTOR in this section of the manual.
