Introduction
Thank you for purchasing the P44 chair-mounted stepper. This device incorporates a unique
leg motion that allows for independent resistance setting, stroke length, and stroke rate from
leg-to-leg. P44 accommodates a decreased knee range of motion better than circular pedal
travel and also acts as a strengthening device, making it ideal to help in the treatment of:
• osteoarthritis
• total knee replacement
• ACL damage
• stroke recovery
• generalgeriatrictness
Time, work, power, and the resistance setting are not only displayed on the LCD, but this
data is stored and can be wirelessly transferred via bluetooth® to a PC for analysis. P44
more accurately charts patient progress electronically.
All of this technology is wrapped in a stylish package that is light weight, highly portable,
and attaches to any 4-legged chair (including wheelchairs) in seconds.
Overview of Parts
Set a chair with a suitable seat
height (at least 17.5 inches from
ground) and chair leg width (so
that pole extends at least 2 inches
past outside legs) in front of P44.
Pull the pole free of P44, grasp
the front handle and gently roll
the device underneath chair seat
far enough that the pole can be
slid behind the front legs.
Slide the pole into the slot in P44,
making sure it catches behind
both front legs and extends at
least 2 inches past each leg.
Attaching to Chair
Improper
chair leg
width could
result in P44
becoming free
of chair legs.
Ensure P44 is
securely
attached via
chair pole
to front legs
before use.

CAUTION
With one hand pull the pedal arm
toward the front of P44 and hold
it while pulling the pin that secures the pedal stop to the pedal
arm with the other hand.
Slide the pedal stop bar towards
the front of P44 for a starting posi-
tionrequiringlesskneeexion
and in the opposite direction for
a starting position that requires
morekneeexion.Thepedal
stop can also be removed from
the slot and inserted the reverse
way for a starting position requir-
ingalmostnoexionatall.
Setting Pedal Stops
Releasing the
pedal arm
while adjusting
the pedal stop
could result in
arm springing
back.
Never induce
a knee exion
that is painful
or uncomfortable.

CAUTION
Manoeuvring Around
The chair attachment pole is also
used as a handle to manoeuvre
P44 around. Insert it into the hole
in the front and lift up. The higher
you lift, the easier it is to push
P44 in a straight line. Avoid pulling P44- the pole can slip out and
it is harder to manoeuvre.
!
CAUTION
Ensure the
pole is in far
enough by
pushing it
into the hole
until you meet
resistance.
Approach P44 attached to a chair
from either side and lift one leg
up and over to the other side.
Sit down with one leg on either
side of P44.
Alternatively, the user can also
beginseatedrstandtheP44
then manoeuvred into place by
someone else.
Place the ball of each foot on the
pedal on both sides.
Getting On
5
Steady yourself on back of
chair.
Extend both legs out together or
alternatively to begin use.
If foot is in
danger of slipping off pedal,
use adjustable strap to
secure.

Setting Resistance (models without LCD)
The resistance is controlled by the
two knobs below the information
sticker. The left knob controls resistance for the left pedal and the
right knob controls resistance for
the right pedal. (From here, you
can also follow the instructions on
the information sticker).
Extend the left pedal out once to
test the current resistance. Turn
the left knob clockwise to increase the resistance and counterclockwise to decrease the resistance.
Extend the left pedal out again
and adjust as required.
Repeat on the right side.
7
Remove the black plastic plug
from the hole located on the
bridge.
Slide the aluminum bracket rod
side down, with the foam pads
touching the P44, into the hole as
far as it will go.
Clip each side-release clip into
the mating end located on each
pedal. Adjust the length of the
strap according to the height of
theuserand/orthedegreeofexion desired.

Scheduled Maintenance: Replacing Brake Pads
Release all tension (turn resistance
knobs counter-clockwise) and
place P44 on its backside.
Disconnect the two leads from
the battery. Remove the battery
(refer to page 13).
The threaded rod that secures the
two brake calipers has a pin in
the centre that needs to be pulled
with a set of needle-nosed pliers.
!
CAUTION
Touching either the metal
of the lead or
the battery
can cause an
electric shock.
17
Slide the rod to the right and
remove the left hand caliper from
the disc by pulling up and away.
Turn it over so that the pads are
visible on the left hand side.
Take a 3/16 allen key and turn
counter-clockwise so that the tab
attached to the top of the pad
itself slides to the left and into the
slot in the caliper.
Grasp the tab attached to the top
of each pad and remove the pads
from the calipers.
18
A new pad is 2.5mm thick and a
pad less than 0.5mm should be
changed. If it is between these
thicknesses, the pad can be reinstalled and tightened, via the
allen key.
After either re-installing the existing pads or replacing with new
pads, use the allen key to tighten
the outer pad with approximately
a 2mm space between the two
pads. Turn over and slide back on
brake disc.
Once re-installed, slide the rod to
the left and repeat the same steps
to check/replace the pads on the
right side. Once both calipers
have been worked on, centre the
rod and replace the pin to secure
it in place. Re-install the battery
and place the P44 back right-side
up.
!
CAUTION
If in doubt,
replace with
a new pad. If
below 0.5mm,
little to no
reistance will
be felt.
!
CAUTION
If the space
between the
pads is less
than 2 mm,
the caliper will
not slide onto
the disc.
