Welcome
Congratulations on choosing the LifeSpan Workplace line of
products. These products give you the opportunity to remain
productive while taking care of yourself as you integrate movement
with normally sedentary tasks.
The average American now spends eleven hours, ve days a week,
sitting, and burns one-hundred fewer calories each day than they did
a few decades ago. Sitting for long periods slows your metabolism,
reduces calories burned, and increases your risk for heart disease and
diabetes.

your desk at home or are adding another workspace in the oce,
the LifeSpan Workplace Solutions products are a great way to add
movement to an otherwise sedentary activity.

Daily Cleaning
It is recommended to wipe the treadmill down after each use to keep the
treadmill clean and dry. A mild detergent may be used at times to help
remove all dirt and salt from the belt, painted parts and the display.
Monthly Cleaning
This cleaning includes removing the motor cover and cleaning around
the motor and electronics. It is recommended to clean the motor
compartment if the treadmill is in an area where there might be plush
carpet bers that could get pulled up into the motor compartment. It
is a good idea at this time to tighten all assembly hardware and check
power cord for damage, or anything else that would indicate the need
for service.
Safety and Integrity
The safety and integrity designed into the machine can only be
maintained when the treadmill is regularly examined for damage and
repaired. Worn or damaged components shall be replaced immediately
or the treadmill be removed from service until the repair is made. Pay
special attention to components most susceptible to wear.
!!
WARNING: Keep treadmill stable on at ground.
WARNING: Unplug the power cord before removing the motor cover.
IMPORTANT: If service is required, turn the power o and remove the
power cord to ensure the unit cannot be used. Let all other users know the
treadmill needs service.
CAUTION: Acidic cleaning detergents may damage painted or powder
coated surfaces and should not be used. Such cleaners may void the
LifeSpan warranty.
!!
Maintenance and Tips Maintenance and Tips
Belt Lubrication
Use only 100% silicone and avoid using aerosol silicone sprays which
include additives and petroleum distillates. One ounce of silicone
should be used for each application. LifeSpan oers 100% silicone
lubricant that can be ordered at www.LifeSpanFitness.com.
The walking belt comes pre-lubricated from the factory. The TR800B
and TR1200B should be lubricated every 50 hours of use. The TR5000B
comes with a maintenance free belt and doesn’t require lubrication.
To lubricate, unplug your treadmill. Slide your hand under the belt and
lift the belt away from the deck. Apply about a dozen sprays toward
the center of the belt from each side. Rotate the belt 1/3 and repeat
this application. Rotate another 1/3 and repeat once more. Plug the
treadmill in and walk for a few minutes to disperse lube evenly.
NOTE: When lubricating the belt, make sure the treadmill
is on a surface that can be easily cleaned. After lubricating
clean any excess silicone o the walking surface of the belt
and side rails.

demonstration

treadmill go to

Belt Tensioning
If the belt begins to slip and needs to be tensioned, tension bolts are
accessible from the back of the treadmill. Before tensioning the belt,
start the treadmill and set the speed to 3 mph (5 kph).
A. Using a 6 mm Allen wrench, included in your hardware bag, turn
the right and left tension bolts 1/2 turn clockwise.
B. Test to see if the slipping is eliminated. If the belt slips repeat step A
and test again.
Note: Adjusting one side more than the other will cause the belt
to drift to the side of the treadmill and will require belt alignment.
Check to be sure the running belt is still aligned. If belt alignment is
o as shown below, refer to Belt Alignment section.
CAUTION: DO NOT tighten more than 2 full turns on each side.
Over tensioning the belt can cause unnecessary friction and wear and
tear on the belt, motor and electronics.
Belt Alignment
A. Press Start, then increase the treadmill speed to 3 mph (5 kph).
B. Stand behind the treadmill to see which way the belt is drifting.
C. If the belt drifts to the left, turn the left adjustment bolt 1/4 turn
clockwise and the right adjustment bolt 1/4 turn counter-clockwise.
(See FIG. 1)
D. If the belt drifts to the right, turn the left adjustment bolt 1/4 turn
counter-clockwise and the right adjustment bolt 1/4 turn clockwise.
(See FIG. 2)
Maintenance and Tips
Belt Alignment (continued)
E. Observe the alignment for two minutes. Repeat steps A-D as
needed.
Visit www.LifeSpanFitness.com for a full video demonstration on the
aligning your treadmill belt.
Moving the Treadmill Base
1. Make sure the ON/OFF switch is turned OFF and the power cord is
unplugged from the wall.
2. Make sure nothing is on or near your treadmill which might spill, be
knocked o, or prevent the treadmill from moving.
3. Place both hands under the support bar located under the back of
the walking belt to make sure you have a solid lifting point.
4. Lift the back of the treadmill and roll to the desired location.

At LifeSpan we strive to make our equipment easy to assemble and start
using. Parts that can be pre-assembled are always assembled and tested
on the product line.
Prior to starting the assembly process, take all the parts out of the box,
remove plastic bags and lay everything out on the oor to become
familiar with the components.
Since your desk is a heavy piece of equipment, it is recommended
that you use two people during assembly and follow these assembly
instructions to reduce any problems that may occur.

Treadmill Desk Innovative Features
Intelli-GuardTM – This treadmill desk is equipped with our patented
Intelli-Guard feature. This feature senses when you stop walking on
the treadmill and for safety purposes, it automatically pauses the
treadmill to avoid accidental falls which may result in injury. The Intelli-
Guard feature is triggered when the treadmill senses you are no longer
walking.
CAUTION: The Intelli-Guard feature will automatically be
disengaged when the treadmill desk is operated at speeds under
1.0 mph (1.6 kph). If the speed is within these parameters, the step
count will ash. When the display for the step count ashes, the
treadmill desk will no longer auto-pause.
CAUTION: At twenty seconds, the console will beep once per
second for ve seconds and then automatically pause the
treadmill desk. These beeps are a caution that the treadmill belt
is about to stop. If for some reason you are still on the treadmill
desk when this occurs, move your feet to the side rails and prepare
for the belt to stop. The Intelli-Guard feature does not replace the
use of your safety key or taking proper precaution in stopping the
treadmill desk when it is not in use.
!!
!!
Intelli-StepTM – This treadmill desk comes with our patented Intelli-Step
counting feature. This feature senses the resistance on the walking belt
each time your foot strikes. There are several factors that will aect the
accuracy of this feature including your walking style, your weight, and
your usage characteristics. For example, the Intelli-Step feature will have
a dicult time picking up the steps of a light user
(under 110 lbs/50 kg) or at speeds lower than 1 mph (1.6 kph).
Treadmill Desk Innovative Features
Audible Safety Alert – This treadmill desk has an audible alert to notify
the user when the treadmill desk is starting as well as when the speed is
being adjusted.
The alert may be distracting in an oce setting and can be turned o.
Please see the Personal Settings section (page 36) for instructions on
how to do so.
CAUTION: If the audible safety alert is turned o, the alert for the
Intelli-Guard feature will also be disabled.
!!
Charging Port (DT-3 Only) – This port can be used to charge your
wireless mobile devices.
NOTE: You will not be able to save your workout data to a USB via
this port; it is used for charging purposes only.
