Introduction
Thank you for purchasing the NuStep®T4r Recumbent Cross Trainer, an innovative product
that empowers users 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 eective 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, eective, 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.

T4r StrideLock® (Not available on all T4r models.)
The NuStep StrideLock feature allows users to lock the arms and pedals of the T4r. Locking the arms
and pedals stabilizes the product, making it easier for users to get on and o. Locking the arms and
pedals also makes it easier to adjust the seat and upper arms. Use of the StrideLock is recommended
when putting on optional adaptive accessories such as the foot secure system and leg stabilizer. (For
information about optional accessories, please visit our website, nustep.com.) To use the StrideLock,
please follow the below instructions.
1. Place the arms and pedals in the desired
position by pushing or pulling one of the upper
arm grips.
2. To lock the arms and pedals, push down on the
StrideLock lever. Verify that the lock is engaged by
pushing or pulling the upper arm grip.
3. To unlock the arms and pedals, push down on
the StrideLock lever again.
Note: Do not attempt to lock the StrideLock while the arms and pedals are in motion.

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
!

11
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 increase work-
load, push lever forward. To
decrease, pull lever backward.
The 10 dierent workload set-
tings appear on the display. The
workload is speed dependent,
meaning, as you step faster, the
resistance increases.
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.
