T4r Feature Overview*

• Features vary based on model and options.

T4r StrideLock

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 off. 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.

• StrideLock is not available on some models.

Preparing to Exercise

Swivel Seat Adjustment
The seat rotates 360o and locks at 45o increments. 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.

CAUTION Make sure the seat and arm positions are correctly set up before exercising.
Do not over-extend your step or reach distance.

Workload Adjustment
The workload adjustment lever is located on the right side of the NuStep. To increase workload, push lever forward. To decrease, pull lever backward.
The 10 different workload settings 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.

CAUTION 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.
