PART ONE: Select L/R switch position and rubber insert.
L/R switch selection:
The SpeedControl device is mounted to either the LEFT or RIGHT side of the wheelchair
frame, depending on which hand you will use to operate the device.
Before attaching the SpeedControl on the wheelchair, check to make sure that the rubber
L/R switch (located on the back of the device) is in the correct position. Switch to "R" for
right-hand use. Switch to "L" for left-hand use.
Rubber insert selection:
Before installation, select the correct rubber insert based on the diameter of the
wheelchair tube. Then follow the instructions in PART TWO.
Note: If needed, use the circumference to determine the diameter of the wheelchair tube.
Use a measuring tape, or cut out a strip of paper, and wrap it around the tube. Use the
table below.
circumference (approximate)
23/4 in (70mm)
31/4 in (80mm)
31/2 in (89mm)
4 in (100mm)
If the wheelchair tube is not round, use the rubber insert that provides the most
secure installation.
Note about rubber insert placement (see PART TWO instructions): During attachment,
you will be placing the rubber insert in the clamp. For correct placement, (A) will fit in the
round opening of the clamp, and (B) will fit in the cutout.
