Thumb Throttle Button Instructions 

[sold separately]

Rigid Frame Mount

The two (2) SmartDrive thumb throttle buttons are easily mounted to 

each side of the wheelchair frame to allow for easy pressing without 

having to remove your hands from the handrims.

1. 

Wrap the velcro loop around the rubber backing of the button 

then around the side tubing of the wheelchair; feed the skinny 

end of the velcro through the slot in the wider end and pull tightly 

before laying down on its mating surface. Be sure the blue LED 

is pointing up and the cables that come out of each button run 

towards the back of the wheelchair (Fig A). 

 

NOTE: If the chair has screw-down seat upholstery, loosen the screws and 

feed the velcro strap under the metal bar (then retighten screws) to allow for 

closer positioning of the buttons to the handrims.

2. 

The cable can be pulled apart to the desired split location [preferably 

in the rear of the seat] and any extra cable can be managed under 

the cushion. Use the provided velcro strips to strap down the button 

cables to the upholstery. Be sure the cables do not stick out and will 

not get caught in the spokes of the wheelchair (Fig. B). Place the 

cushion over the cable to further secure the cable.  

3. 

When the connector is not connected to the SmartDrive, it can 

be magnetically connected to the provided metal holder (Fig. C). 

Position the metal hold between the front and back parts of the 

clamp, feeding the top screw through the hole in the holder. To 

prevent rattle, tighten the top screw of the clamp completely before 

tightening the bottom screw. 

4. 

The position and orientation outlined in the Adaptive Clamp 

Mounting Instructions are 

critical

 to the proper function of Smart-

Drive and must be heeded. Refer to that instruction to make sure 

the clamp is oriented correctly.

NOTE: Parts shown may differ slightly from your SmartDrive.

2. 

The cable can be pulled apart to the desired split location (preferably in 

the rear of the seat) and any extra cable can be routed at the rear of the 

seat.  Use the provided tie-straps to route the cables along the frame tubes 

and out of the rear of the wheelchair.  Be sure the cables do not stick out 

and will not get caught in the spokes of the wheelchair (Fig. E).

3. 

When not in use the cable can be left to dangle out the back.  Be sure 

to leave enough slack to allow the cables to fold up with the wheelchair 

when the chair is collapsed.
