Otherwise injury or damage may occur. 11.1 Changing Seat-to-Floor Height ƽ WARNING The size/position of the front casters, position of the rear wheels, use of anti-tipper model, as well as the user condition directly relate to the stability of the wheelchair. Any change to one or any combination of the five may cause the wheelchair to decrease in stability. These adjustments must be performed by a qualified technician. Seat-to-floor heights have specific positions depending on rear wheel position and front caster position. These adjustments must be performed by a qualified technician. If changing the seat-to-floor height, the anti-tippers MUST be adjusted to maintain a 11/2 to 2-inch ground clearance.  For this procedure, refer to FIGURE 1 on page 58. 1. Refer to the chart in FIGURE 1 on page 58 to determine mounting positions for front casters/forks and rear wheels for the desired obtainable seat-to-floor height: 2.

WARNING

The size/position of the front casters, position of the rear wheels, use of anti-tipper model, as well as the user condition

directly relate to the stability of the wheelchair. Any change to one or any combination of the five may cause the wheelchair

to decrease in stability. These adjustments must be performed by a qualified technician.

Seat-to-floor heights have specific positions depending on rear wheel position and front caster position. These adjustments

must be performed by a qualified technician.

If changing the seat-to-floor height, the anti-tippers MUST be adjusted to maintain a 1
