Introduction
Thank you for purchasing the NuStep®T4r Recumbent Cross Trainer, an
effective way to improve cardiovascular and overall fitness.
T4r recumbent cross trainers are suitable for physical therapy, cardiopulmonary
rehabilitation, sports medicine and general fitness purposes.
NuStep recumbent cross trainers set an unparalleled standard for total body
exercise. By combining a natural sitting position with a smooth stepping
motion, the NuStep works all major muscle groups, giving you an effective
cardiovascular workout in a comfortable seated position.
The unique design lets you move your arms and legs in a single, dependent,
fluid motion that simulates walking, with the added benefit of resistance
training. Working the upper and lower body simultaneously uses more muscles
and burns more calories.
As the originator of the recumbent cross trainer, NuStep is the leader in
developing total body exercise systems that are safe, effective, and easy-
to-use. Our products are used in healthcare facilities, wellness centers, and
senior living residences around the world, and millions of NuStep users have
transformed their lives through exercise – even when they were unable to use
other exercise equipment.
Thank you for your business and welcome to our ever-expanding network of
NuStep users.

Preparing to Exercise
Swivel Seat Adjustment
The seat rotates 360oand
locks at 45oincrements.
This provides users with
eight convenient positions
of access to facilitate easy
transfer to the seated
position. To swivel the
seat, lift up on the swivel
release lever directly under
the rear and sides of the
seat. Swivel the seat left or
right until it locks into the
desired position. To swivel
back to the original forward
facing position, lift up on
the release lever again. The
arm rests lift up and down
to allow easier access to the
NuStep.
Note: The seat cannot be
adjusted forward and back
as described in the next
section unless the seat is
locked in the forward facing
position.
Seat Adjustment
The seat position may be
adjusted forward and back
by lifting up on the seat
release lever located directly
under the front and sides
of the seat. With both feet
on the foot pedals, push
one foot pedal all the way
forward to the end of the
pedal range limit. Lift the
seat release lever, and slide
the seat forward or back
until your extended leg has
a slight bend at the knee
(avoid over-extending your
legs and/or locking your
knees during exercise).
This position allows your
legs to be slightly bent
during exercise; avoid over-
extending and striking the
pedal bumper excessively.
Try the motion to verify
the position allows for a
comfortable exercising
motion. If not, slide the
seat forward or backward
one notch until it feels
comfortable. The seat
number position appears on
the console while the seat is
being adjusted.
Arm Adjustment
To adjust the upper arm
length, lift the green release
lever on the arm. Adjust the
upper arm length until your
elbow is slightly bent at the
extended point of the arm
stroke. (For many users,
the arm position number
matches their seat position
number.) Press the green
release lever down to lock
the upper arm.
Make sure the seat
and arm positions are
correctly set up before
exercising.
Do not over-extend
your step or reach
distance.
CAUTION
!

9
Preparing to Exercise
This product has arms
and pedals that move
during operation.
To avoid injury due
to contact with these
moving parts, use
caution while making
adjustments during
operation.
CAUTION
!
Workload Adjustment
The workload adjustment
lever is located on the right
side of the NuStep. To in-
crease workload, push the
lever forward. To decrease,
pull lever backward. The 10
different workload settings
appear on the display. The
workload is speed depen-
dent, meaning, as you step
faster, the resistance in-
creases.
Step Length
The NuStep allows you
to determine your own
desired range of motion.
The maximum step length
is approximately 8.5 inches
(22 centimeters). For smaller
ranges of motion, simply
take shorter steps.
Foot Position
The NuStep’s stepping
action works virtually all leg
muscles. Instead of pushing
with your whole foot, which
works your quadriceps and
hamstring muscles, push
with the balls of your feet
to work your calf muscles.
As shown above, your arm and leg should
have a slight bend at the fully extended point
of the stroke.

Programs
The T4r recumbent cross trainer has two exercise programs, “Quick Start” and “Pace Partner”.
After adjusting the seat and upper arms according to the “Preparing to Exercise” section of
this manual, choose either the “Quick Start” or “Pace Partner” program. Note: Entering user
weight is optional for both programs. However, entering user weight increases the accuracy
of calorie and METS outputs. Refer to the “Console Operation” section of this manual for
information on entering user weight.
Quick Start
The Quick Start program is a basic program that allows users to start exercising immediately
without entering any information into the console. After pressing the QUICK START button,
begin stepping and adjust work load as needed. (Note: If the user begins stepping without
pressing any console buttons, the QUICK START program will start automatically.)
Pace Partner
This program enables users to more accurately maintain a steady pace by providing a pace
partner that is displayed in the main console window. The pace partner is represented by
blinking arrow heads that move around the lap track. The goal of the program is for users
to consistently match the pace of the pace partner as it moves around the track. During
program set up, users may select their preferred Steps Per Minute (SPM) pace.
Press the PACE PARTNER button to begin program set up. The default pace partner pace
will appear in the SPM display. To increase or decrease the default SPM pace, press the pace
partner - or + buttons until the desired pace displays in the console window then press the
SELECT button to complete the program set up. Start stepping and increase your stepping
speed so you are able to keep up with your pace partner. During your workout, you may
increase or decrease the selected pace by using the - or + buttons.
During your PACE PARTNER workout, the PACE PARTNER icon will appear in the main
console window to indicate that a PACE PARTNER program is selected.

file with incremental workout data will be saved to the flash drive approximately every five
minutes. The data is compatible with the web based Interactive Health Partner. Note: The
USB symbol on the console will not appear during the first five minutes of the workout.
Thereafter, the USB symbol will appear and will blink when data is being downloaded to the
flash drive. To ensure that all workout data is properly downloaded to the flash drive at the
end of your workout, do not remove the flash drive from the console until your workout is
complete, the workout timer on the main console display has stopped and the USB symbol
has stopped blinking.
