9.1 Using Optional Wheel Hubs
1. Perform one of the following:
• Disengage (Free Wheel) - Pull out on engagement knob and rotate engagement knob approximately 1/6-turn until the pins on the
engagement knob fall into the free wheel detents on the wheel hub (Detail “A”).
• Engage (Drive) - Pull out on engagement knob and rotate engagement knob approximately 1/6-turn until the pins on the engagement knob
fall into the holes in the wheel hub and axle sleeve. Gently rock the wheelchair until the engagement knob snaps into place (Detail “B”).
After ANY adjustments, repair or service and before use, make sure that all attaching hardware is tightened securely -
otherwise injury or damage may result.
As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced.
Wheel hubs are not available on Heavy Duty GB motors.
If the pins on the engagement knob are not in the free wheel detents, the engagement knobs can engage the motors
unexpectedly while the wheelchair is being pushed.
