Folder Adaptor Bar Mounting Instructions
Folder Adaptor Set-Up
e attachment hardware for folding frame wheelchairs is an adjustable length adaptor bar that attaches to the drive unit and engages
the wheelchair’s quick-release axle tips [or other part if these are recessed/inaccessible - see separate Insert instructions].
First, verify that you have the correct adaptor attachment based on the size of the rear wheels. e attachment size is labeled on it’s
bottom side with either a 24, 25 or 26 (Fig. A). See the chart below for the mount that goes with each wheelchair rear wheel/tire size.
22” (501) Wheel / Tire Use 24 attachment End Tube Wheelchair Seat Widths
24” (540) Wheel / Tire Use 24 attachment Narrow [MX2-4FN] Up to 13” (330 mm)
25” (559) Wheel / Tire Use 25 attachment Regular [MX2-4FR] 14” (356 mm) to 18” (457 mm)
26” (590) Wheel / Tire Use 26 attachment Wide [MX2-4FW] 19” (483 mm) and Up
Next you will want to adjust the adaptor bar to the correct width for the wheelchair. Loosen the set screws [do not remove completely]
on the end tubes so that the bars can slide along the shaft of the adaptor attachment (Fig. B).e chart above species which end

tubes most likely work with dier-
ent folding wheelchair seat widths.
NOTE: If the quick-release axle tips
are recessed or not accessible, use the
provided inserts and instructions to
engage another part of the wheelchair
before continuing.

Adjustments made to the wheelchair set-up could aect the orientation of the folding adaptor bar. Adjust the adaptor bar
whenever changes are made to the chair.

Next mount the folding adaptor bar onto the chair, again with the”T” bar facing away from. Place one end cap over the axle tip. Grab-
bing the other end cap, compress the springs inside the bar (Fig. F) and place over the opposite axle tip (Fig. G). If set up properly, the
inside edges of the end caps will be within the white strips of the tube (Fig. H). If not, adjust the number of dimples visible as needed
to achieve the proper spring pre-load setting as indicated by the end caps edge being over the white strips. Once this is set with the
proper amount of pre-load, tighten the other two set screws [one on each side that don’t engage dimples] to help secure the end tubes.
While looking at the rear of the chair, hold the adaptor bar, so that the “T” bar is away from you and you can see the white stripes on
the back of the end tubes. Place one of the end caps over one of the axle tips and slide the other end out and place it over the opposite
axle tip. Now move the adaptor attachment until it is centered (Fig. C). Note the number of dimples visible on the bar of the adaptor
attachment [they should be the same number on both sides] (Fig. D). Remove the assembly and move the adjuster bars outward so
that you can see the same amount of dimples that you noted before.en move it ve (5) more further for consideration of the spring
loaded end caps [i.e. you count two (2) exposed dimples then move the adjuster bars out so you have seven (7) exposed dimples] (Fig.
E). Position the set screws in the correct dimples then tighten, checking so the correct number of dimples show on each side.

Drive Unit / Folder Adaptor Mounting
Once set-up is completed, mounting of the drive unit to the adaptor bar is needed.e drive unit should be pre-attached to the folder
adaptor bar prior to installation onto the wheelchair. First, slide the custom t rubber stopper into the gap on the drive unit (Fig. I).
Lower the drive unit over the attachment protrusions (Fig. J) and rotate downward until it stops (Fig. K).

e two spring loaded end caps engage the quick-release axle tips of the folding frame wheelchair that protrude out of the axle
receiver plugs.ese spring loaded end caps are compressible to allow for clearance and then released to be positioned over these axle
tips (Fig. O).e tension force of the springs constantly push out to prevent the adaptor bar from coming o the wheelchair until it
is desired, at which point the end caps are compressed and the adaptor bar/drive unit are removed.
If buttons were purchased, refer to their separate instructions for
mounting directions. e buttons plug into to the drive unit using
the magnetic connector that snaps into the receptacle on the drive
unit housing (Fig. P) .
Refer to the User’s Manual for SmartDrive operation.
Drive Unit Attachment
Making sure the wristband is o, power on the drive unit by ipping the toggle switch to the on position prior to attachment. “On” is push-
ing the toggle away from the front of the drive unit (Fig. N). You will get a loud beep and the blue LEDs will illuminate as indication.
