unattended, on slopes or near stairs.
• Note that a lack of knowledge of the instructions for use can lead to injuries
due to user error. Read the instructions for use rst. Prior to use, familiarise
yourself with the handling and function of the product and practice using it.

ASSEMBLY INSTRUCTIONS
Set-up and assembly of the KidWalk/Kid-
Walk II is easy when these directions are
followed.
First:
Open carton, remove and identify the following
assemblies and components.
ABase frame with anti-tipper
BAdapter column with self-centring pelvic
guide
CWheels (2)
DBag containing axles and spacers
• Optional accessories (if ordered)
Assembly:

as shown in Fig. 1.
• Remove axles and axle spacers from plas-
tic bag. From the side with the recessed
bearing, insert the axle into the wheel (Fig.
2). Push in the button at the end of the
axle during this process so the axle can
slide all the way through the wheel bea-
ring. Assemble one spacer onto the axle
at the back of the wheel as shown in Fig. 2
while holding the axle button in.
• Attach the wheel with the quick-release
axle to the centre position of the wheel
brackets on the base frame (Fig. 3). Re-
peat procedure on opposite side.

for initial setup.
The wheel locks and anti-tipper are preset
for the centre axle position.

per end of the receiver tube. Set the pads
at proper heights and tighten both adjust-
ment screws (Fig. 6).
• Pull the locking pin for the adapter column
on the rear of the base frame and rotate it
one-quarter turn so it locks (Fig. 4).
• Set the adapter column onto the guide
pins on the base frame (Fig. 5). Rotate
the locking pin until it engages in the
adapter column. Make sure that the re-
lease pin is fully engaged and the adap-
ter column is rmly connected to the base
frame. If the adapter column can be lifted
off the base frame, continue turning the
locking pin until it engages in the adapter
column.

MEASUREMENTS & INITIAL SETUP
Measurements:
The following measurements should be taken and
recorded for the setup of the KidWalk/KidWalk II:
• Inseam __________ inch (cm)
• Hip width __________ inch (cm)
• Chest width __________ inch (cm)
• Thoracic height* __________inch (cm)
• Head height* __________ inch (cm)
*Thoracic height and head height measurements
should be taken from the top of the inseam. These
measurements are needed to adjust the optional en-
compassing thoracic support and/or head pad/head-
rests available for the KidWalk/KidWalk II.
KidWalk/KidWalk II initial adjustments:
Seat height:
• Using the height adjustment/release handle or
the ne adjustment handle (Fig. 10), adjust the
seat height to 1 inch (2.5 cm) higher than the
inseam measurement.
• To raise the seat with the height adjustment/
release handle, press down on the top of the
adapter column with one hand while pulling up
the height adjustment/release handle with the
other hand.
• To raise the seat using the ne adjustment, put
your hand through the ne adjustment handle
and pull the lower section of the handle up (Fig.
10). Each time you squeeze the ne adjustment
handle, the seat will rise up by one-half inch
(1.3 cm).
• To lower the seat, simply press down slightly
on the height adjustment/release handle (Fig.
10). Only minimal force is needed to lower the
seat on the adapter column. Do not push the
seat down too hard. As soon as the height ad-
justment/release handle is no longer pressed
down, the seat remains at the current height.
(Seat cannot be lowered while bearing weight.)

Other items:
Make sure that all supports are set to a suitable
height and width for the user. Adjust any optional
items to match the measurements for height and
width per the instructions included here.
NOTICE: Set all depth-adjustable pads so far for-
ward that the user ts into the system when the
pads are ipped down.

INITIAL ADJUSTMENTS
Pelvic guide
• Flip the front pelvic guide pads upward
and outward (Fig. 11). If the KidWalk/
KidWalk II is also equipped with upper
encompassing thoracic pads, ip them up-
ward and outward as well.
• Adjust the distance between the pelvic
pads using the rotary knob on the outside
of the pelvic pads (to the left of the user,
Fig. 13) so that the user ts easily bet-
ween the pads. Turning the knob clockwi-
se makes the assembly wider while coun-
terclockwise narrows the hip pad width.
Encompassing thoracic pads
(optional item)
• Loosen the knobs on the back side of the
upper thoracic pads (Fig. 12). Then slide
the pads out far enough so that the trunk
of the user ts through (these pads are re-
adjusted after the user is positioned in the
KidWalk/KidWalk II).
Information: To place the user in the sys-
tem, turn the ip pads forward and tighten
the adjustment knobs so the pads stay tem-
porarily in position.
Placing the user in the KidWalk/KidWalk II
• First engage the wheel lock.
• Then place the user in the system, making
sure to push the hips back as far as possi-
ble in the KidWalk/KidWalk II. Once the
user has been positioned back in the seat,
fold down the front pads. Then slide the
front hip pads toward the user until they
are snug and holding the user's hips in
place. Tighten the depth adjustment knob
securely (Fig. 13).

Adjusting the hip width
• Use the rotary knob on the outside of
the pelvic pads to adjust the distance
between the supporting elements in
the area of the hips so the elements t
snugly on the user's hips.
• Fasten the buckles and pull the strap
snug (Fig. 14).
Information: Position the user's hips
back as far as possible. The further
back the user sits on the seat, the better.

INITIAL ADJUSTMENTS/POSITIONING THE USER
Adapter column angle (adjustable)
Once the user has been placed in the KidWalk/
KidWalk II and all supporting elements are ad-
justed properly, it may be necessary to adjust the
angle of the adapter column. The adapter column
of the KidWalk/KidWalk II can be angled to the
front or back as required. The adapter column
should be moved in small increments to assist in
positioning the user or improve the gait.
Turn the angle adjustment knob (Fig. 15) clockwi-
se to angle the column forward and counter-clock-
wise to angle it backward.
Seat depth adjustment
The seat has been adapted at the factory to align
with the centre axle position on the frame. If it is
necessary to alter the depth of the seat, loosen
the two adjustment screws (Fig. 16). Slide the seat
forward or rearward as required and re-tighten the
screws.
Changing the wheel position
The large wheel can be mounted in three different
positions. To change the position, press and hold
the axle pin knob (Fig. 17) and pull the wheel off
the frame to the outside. With the axle pin pressed,
insert the wheel in the new position. After locating
the wheel, make sure that the axle has fully enga-
ged and will not pull out.

• Make sure that both screws that hold the seat
were rmly tightened again.

frame has been changed, the wheel lock has
to be adjusted accordingly (see "Changing the
wheel lock position").
CAUTION
CAUTION

KidWalk/KidWalk II 16
POSITIONING THE USER
Changing the wheel lock position
• The wheel lock is pre-set at the factory to
the centre wheel position. If the position
of the large wheels is changed, the wheel
locks must be adjusted accordingly.
• To change the position of the wheel lock,
rst remove the thumb screw (Fig. 18).
Then move the wheel lock forward or
back to coincide with the new wheel posi-
tion. Align the threaded hole for the thumb
screw with the front or rear hole (Fig. 18).
Re-install the thumb screw and tighten se-
curely.
Optional accessories:
Encompassing thoracic supports
Height adjustment
Slide the encompassing thoracic pad up or
down on the expansion tube until the desired
height is reached. Tighten the height adjust-
ment screw securely (Fig. 19).
Width adjustment
Slide pads inward, making contact with the
body in the desired upper body posture and
tighten the adjustment screws (Fig. 19).
Flip front lateral pads down into place, snap
the buckles together and pull the straps snug.
Depth adjustment
Adjust the depth of the forward chest pads
to hold the upper body rmly against the rear
pads. (Fig. 19).
Head pad
Adjust the head pad height and depth to desi-
red location and tighten the adjustment knobs
(Fig. 20).

The KidWalk/KidWalk II supports the user with
independent walking. Corrections to the walking
direction and speed can be made by the attendant
by adjusting the adapter column, the automatic
pelvic centring devices or the encompassing tho-
racic supports.
To overcome obstacles, the KidWalk/KidWalk II
without the user can be lifted on the base frame by
two persons. Before doing so, remove the wheels
or engage the wheel lock.
All components of the KidWalk/KidWalk II must
be disposed of properly in accordance with the re-
spective national environmental regulations.
