If you're over 55, pay careful attention - iWALK2.0 might not work for you.
Physical ability is more important than how old you are. And it varies from
person to person, especially as we age.
So regardless of your age, if you do not meet ALL the requirements listed above,
then iWALK2.0 isn't going to work for you.
If you meet the requirements listed above, iWALK2.0 will work for you.

STEP 1
With the Handle facing forward, insert the Upper Assembly tubes
into the sockets of the Knee Platform.
Push down rmly on the
Handle to make sure both
tubes are fully bottomed out
in the sockets. You may have
to pull down on the left side
tube in order for it to reach the
bottom.
Make sure that the holes at
the bottom of the tubes align
with the holes in the side of
the Knee Platform.You may
need to pull down and/or rotate
the left side tube for it to align.
WARNING – do not
continue with assem-
bly unless both left and
right side holes have
aligned.

STEP 2
Attach the Lower Assembly to the Knee
Platform by pressing in the spring head
at the top of the Lower Assembly tube
and inserting the tube into the socket
of the Knee Platform. Grasping the tube,
pull down forcibly to insure that the two
parts are securely locked together.
A) Identify the Right side Support Tube by the small“R” stamped near the top.
B) While pushing down on the Upper Assembly tube , press in the silver spring head and insert the
Support Tube into the bottom of the Knee Platform socket until the spring head engages in the
holes of the Upper Assembly tube AND the Knee Platform. All three must be locked together.
C) Test the connection by rmly grasping the Upper Assembly tube with one hand and the Support
Tube with the other and forcibly try to pull them apart. If you cannot pull them apart, you have
assembled the three components correctly.
D) Insert the Left side Support Tube using the same procedures. You may need to rotate the tube
in order to align the hole.
CBA
WARNING – Aggressively test both connections (left and right). If the Support Tube, Knee
Platform and Upper Assembly tubes are not locked together, instability and injury can result.

STEP 4 STEP 5
Insert the Thumb Screw into the slot on either side of the top of the Handle. Align
the hole in the top of the Thigh Support with the threaded end of the Thumb Screw.
Thread theThumb Screw into the nut located on the underside of theThigh Support
(you can see it from underneath). Do not fully tighten yet, you should be able to
rotate the Thigh Supports in and out.
Note – If the Thumb Screw will not fully tighten, check the underside of the
Thigh Support and make sure there is a silver nut nested in the hex shaped
cavity. Be careful not to accidentally push this nut out when pushing the
Thumb Screw down.
If you lose the nut, don’t panic – you can call us for a replacement or nd one at a
local hardware store. The specication is M5 x .8 (metric, 5mm, .8 pitch)
Note – Clamp should be centered between the
Support Tube ends. Realign if necessary using
a screwdriver or similar.
The Clamp should be
positioned between
the at ends of the
Support Tubes. If
not, you can remove
the Support Tube
and reinstall. Gently
push on the ends of
the Support Tubes
to align the holes
with the hole on the
Clamp, then insert
the Clamp Bolt and
secure with the Clamp Nut. Do not tighten yet.

STEP 1
Fitting
Instructions
Make sure that Thigh Supports can rotate
freely. If necessary, loosen Thumb Screws.
Proper t is essential!But it’s also easy. Get these three things right and you’ll be
iWALKing in minutes. We’ll show you how.
Height
Adjust both the upper
and lower section of the
crutch to the correct
height.
Tight
For control and stability,
you want the straps tight!
Really, really tight!
Vertical Alignment
Essential for quick
learning, and often
overlooked, the vertical
angle controls where the
foot will be positioned.

STEP 2
Foot Positioning (for Left or Right) - Position the Foot so that
the curved edge is toward the outside of your leg. To reposition
the foot,
1. Loosen the Clamp Bolt.
2. Press in the height adjustment springs as shown below.
3. Continue pressing; simultaneously grasp and rotate the Foot
180 degrees until the spring heads pop out of the adjustment
holes.
Note - The Foot and lower tube will rotate . The upper
tube stays stationary.

Improper orientation of the Foot causes instability which
could result in a fall and/or injury.

STEP 3
Lower Leg Height Adjustment - The“V”at the back of the Knee Platform
should align with a point ½” – 1” below the bottom of your kneecap.
This will result in your iWALK leg being slightly shorter than your human
leg. If in doubt about the correct height setting, it’s better to adjust the
crutch slightly too low than too high.
To adjust the height:
A) Loosen the Clamp Nut and Bolt.
B) Press in the two silver spring heads. Grasp the Foot and rotate slightly
back and forth while pulling or pushing to the desired length. When
both spring heads are fully engaged in their new position, tighten the
Clamp Nut and Bolt.
C) Conrm correct height setting before proceeding.
Note – After you gain basic prociency, you will readjust the lower leg height
to achieve equal leg length.
Before putting
weight on the
crutch, make
certain that both spring
heads are fully engaged
(“popped out”) in the
adjustment holes. Then
tighten the Clamp Bolt.
Failure to do so could
result in a fall and / or
injury.
