Preventive Maintenance Tips
NOTE: Safety of the equipment can be maintained only if the equipment is examined regularly for damage or wear.
Keep the equipment out of use until defective parts are repaired or replaced. Pay special attention to parts that are
subject to wear, as outlined below.
The following preventive maintenance tips will keep the product operating at peak performance:
• Locate the product in a cool, dry place.
• Clean the display console and all exterior surfaces with an approved or compatible cleaner (see Approved and
Compatible Cleaners) and a microfiber cloth.
• Long fingernails may damage or scratch the surface of the console; use the pad of the finger to press the selection
buttons on the console.
• Check operation of the emergency stop system once a week.
• Inspect and vacuum the area directly surrounding and under the unit regularly.
• Vacuum around the striding belt regularly to keep debris from accumulating.
• Inspect exterior parts regularly for wear, particularly the striding belt, deck and line cord.
• Check to make sure the unit is properly leveled.
• Check the position (centering) of the striding belt.
NOTE: Normal belt operating position is for the belt to be located within the belt travel indicators on the rear roller
guards. Refer to Tracking (Centering) A Striding Belt or contact Customer Support Services for proper alignment
instructions.
Approved and Compatible Cleaners
Two preferred cleaners have been approved by reliability experts: PureGreen 24 and Gym Wipes. Both cleaners
will safely and effectively remove dirt, grime and sweat from equipment. PureGreen 24 and the Antibacterial Force
formula of Gym Wipes are both disinfectants that are effective against MRSA and H1N1.
Page 7 of 98

PureGreen 24 is available in a spray which is convenient for gym staff to use. Apply the spray to a microfiber cloth
and wipe down the equipment. Use PureGreen 24 on the equipment for at least 2 minutes for general disinfection
purposes and at least 10 minutes for fungus and viral control.
Gym Wipes are large, durable pre-moistened wipes to use on the equipment before and after workouts. Use Gym
Wipes on the equipment for at least 2 minutes for general disinfection purposes.
Contact Customer Support Services to order these cleaners (1-800-351-3737 or email:
customersupport@lifefitness.com).
Mild soap and water or a mild non-abrasive household cleaner can also be used to clean the display and all exterior
surfaces. Use a soft microfiber cloth only. Apply the cleaner to the microfiber cloth before cleaning. DO NOT use
ammonia or acid based cleaners. DO NOT use abrasive cleaners. DO NOT use paper towels. DO NOT apply cleaners
directly to the equipment surfaces.

Belt Adjust and Tension
Tools Required:
8 mm Allen wrench
Time:
15 minutes
How to Adjust and Tension the Striding Belt
Do not move the treadmill or place hands under the treadmill while it is plugged into an electrical outlet!
Belt Tensioning Bolts
An 8mm hex key wrench is required for this task. The treadmill has access holes in the rear roller guards which allow
access to the tensioning bolts. These tensioning bolts make it possible to adjust the tracking and centering of the
striding belt without removing the guards.
NOTE: It is extremely important that the treadmill be correctly leveled prior to any tracking adjustments. An unstable
unit may cause striding belt misalignment. See How To Stabilize the Treadmill prior to attempting any rear roller
adjustments.
Before proceeding, it is helpful to visualize the pivot point of the rear roller. Each adjustment made to one side of
the roller must be met with an equal and opposite adjustment to the other side of the roller to maintain an ideal belt
tension at the pivot point.
Item Description Qty.
1 Belt 1
2 Rear Roller 1
3 Pivot Point of Rear Roller 1
Tracking (Centering) A Striding Belt
Two people are needed to perform this procedure.
1. Locate the two access holes to the belt tensioning bolts on each of the rear roller guards.
2. One person stands on the side rails of the treadmill and straddles the belt. This person presses GO and sets the
belt speed to 2.5 MPH (4.0 KPH).
3. If the striding belt has moved to the right, the second person turns the right tension bolt a quarter-turn clockwise
and then turns the left tension bolt a quarter-turn counter-clockwise to make the striding belt track back to the
center of the roller. If the striding belt has moved to the left, turn the left tension bolt a quarter-turn clockwise and
then turn the right tension bolt a quarter-turn counter-clockwise to make the striding belt track back to the center
of the roller.
NOTE: If the striding belt has moved as far as to the edge of the roller (either right or left side), it must be
re-centered per the above procedure.
4. Repeat the adjustments until the striding belt appears centered. Allow the machine to continue running for several
minutes at 4.0 MPH. (6.4 KPH) to observe if tracking remains stabilized.
NOTE: Do not exceed one full turn of the adjusting screws in either direction. If after one full turn the belt does not
track properly, contact Life Fitness Customer Support. Do not overtighten the tensioning bolts while making belt
adjustments. Overtightening of bolts may over stretch and damage the striding belt or roller.
Page 10 of 98

Tensioning an Existing Striding Belt
1. Press GO and operate the treadmill for five minutes at 5.0 MPH (8.0 KPH).
NOTE: Do not run or walk on belt!
2. Reduce the speed to 2.0 MPH (3.2 KPH). Walk on the treadmill. Tightly grip the handrails and apply force with feet
on the striding belt near the motor cover against the moving belt direction. If the belt slips, continue to Step 3. If it
does not slip, the tension is correct.
3. Using the STOP key, stop the treadmill. Turn the belt tensioning bolts a quarter-turn clockwise for each side.
4. Repeat STEPS 2 and 3 until the belt no longer slips. Do not exceed one full turn (four quarter turns) per side when
adjusting the belt tensioning bolts.
5. Press GO, operate the treadmill at 2.0 MPH (3.2 KPH) and check to insure proper tracking (see Tracking (Centering)
A Striding Belt). If the striding belt drifts to the left or right see Centering an Existing or New Striding Belt .
Do not overtighten the tensioning bolts while making belt adjustments. Overtightening of bolts may over stretch
and damage the striding belt or roller bearings. Do not exceed one full turn of either bolt in either direction.
