Do not use the uprights, handlebars, or the Console to lift or move the machine.

Injury to you or damage to the machine can occur.

The machine may be moved by one or more persons depending on their

physical abilities and capacities. Make sure that you and others are all

physically t and able to move the machine safely.

Place the machine on a clean, hard, level surface, free from unwanted material

or other objects that may hamper your ability to move freely. A rubber mat

should be used below the machine to prevent the release of static electricity

and protect your ooring.

For safe storage of the machine and to prevent unsupervised operation of the

machine always remove the Safety Key and disconnect the power cord from the

wall outlet and the AC input. Place the power cord in a secure location.

Adjustments

Leveling Your Machine

Levelers are found on the front of the TreadClimber®machine. Make sure the TreadClimber®machine is level and stable before you exercise. To

adjust:

1. Loosen the upper locking nut.

2. Turn the leveler to adjust the height.

3. Tighten the upper locking nut to lock the leveler.

Do not adjust the levelers to such a height that they

detach or unscrew from the machine. Injury to you or dam-

age to the machine can occur.

MAINTENANCE

Read all maintenance instructions fully before you start any repair work. In some conditions, an assistant is required to do the necessary tasks.

Equipment must be regularly examined for damage and repairs. The owner is responsible to make sure that regular maintenance is

done. Worn or damaged components must be repaired or replaced immediately. Only manufacturer supplied components can be

used to maintain and repair the equipment.

To reduce the risk of electrical shock or unsupervised usage of the equipment, always unplug the power cord from

the wall outlet and/or the machine and wait 5 minutes before cleaning, maintaining or repairing the machine. Place the power cord in a

secure location.

Daily: Before each use, inspect for loose, broken, damaged, or worn parts. Do not use the machine if any of these conditions exist. Use a

dry cloth to wipe off any perspiration after each use.

Weekly: Check for smooth roller operation. Clean the machine to remove dust, dirt, or grime. Clean the top of the belt with a slightly damp,

soapy cloth and wipe carefully and thoroughly with a dry cloth. Do not let any liquid get below the belts or into the Base Frame.

Monthly: Make sure all bolts and screws are tight. Tighten if necessary.

NOTICE: Do not clean with a petroleum based solvent or an automotive cleaner. Be sure to keep the Console free of moisture.

Walking Belt and Deck Lubrication

The TreadClimber®machine is equipped with a low maintenance deck and belt system. Belt friction can affect the function and life of the machine.

Your TreadClimber® tnessmachinecamewithastartersupplyoflubricationforthebelts.

Lubrication Schedule

User Level Total Workout Hours per Week When to Lubricate

Light less than 3 hours every 3 months

Moderate 3 to 5 hours every 2 months

Heavy 5 or more hours every month

We recommend that you use one of the following:

• Lube-N-Walk®Treadmill Lubrication Kit (available from www.bowflex.com or your local specialty fitness dealer)

• 100% pure silicone, available at most hardware and auto parts stores.

Asyouuseyourtnessmachine,theConsolewillshow“LUbE”atsettimes.Thisisonlyareminderandshould be added to your inspection

schedule. Only apply lubricant as necessary. Push the START button to accept the reminder.

For the best results lubricate the Treadles periodically with a silicone lubricant, using the following instructions:

1. Unplug the machine fully from the wall outlet, and remove the power cord from the machine. Place the power cord in a secure location.

2. Carefully lift each belt and apply silicone lubricant in the center of the Treadle deck along the entire reachable length of the deck. Apply 0.5 to 1.5

oz. of the lubricant on the deck underneath each belt.

NOTICE: Always use a 100% pure silicone lubricant. Do not use a degreaser like WD-40®or a petroleum based product as this could

seriously impact performance.

Note:TheWalkingBeltsmayneedtobeloosenedtoallowforaccessduringlubrication.Consultthe“AdjustingtheWalkingBelts”procedure

if necessary.

3. Connect the power cord back into the machine and then into the wall outlet.

4. Stay to one side of your machine.

5. Switch on your machine and start the belts at the slowest speed. Let the belts operate for approximately 15 seconds.

6. Switch off your machine.

7. Take care to clean up any excess lubricant from the Treadles. We also recommend a periodic inspection of the Treadle surfaces below the belts.

If the decks appear worn, contact a TreadClimber Representative (refer to the Contacts section of this manual).

To decrease the possibility of slipping, be sure the Treadle area is free from grease or oil. Clean off any excess oil from the machine

surfaces.

Walking Belt Alignment

The walking belts need to be adjusted if they are out of center enough to cause a rubbing or scraping sound. Adjustments can be made at the Front

Roller of each Treadle.

Adjusting the Walking Belts – While operating the machine, notice where the belts run on each Treadle. The Walking Belt Adjustment Bolts are on

the front end of each Roller. If the belt is tracking too far to the right, use a properly sized Hex Key to turn the right adjustment bolt clockwise on that

belt in full turn increments. If the belt tracks too far to the left, do the same thing on the left adjustment bolt.

Note: Do not turn the bolts counterclockwise when you adjust the belt alignment.

Belt Tension Check – Check the belt tension only when the machine is unplugged. From the belt’s midpoint, a correctly tensioned belt should only

have an inch of give. To check, pull the belt upward at its midpoint and measure the distance to the deck. If the distance is more than an inch, the

belt is loose. To tighten, turn both Walking Belt Adjustment Bolts clockwise one-half a turn and check tension again. Repeat this step if necessary.

Note: Bolts are turned counterclockwise equally to decrease belt tension.

ence are present, or console has been tested with a Pulse Simulator and is

not receiving the signal, contact Customer Care for replacement HR receiver.

Walking belt misalignment Rear belt guides Belts should ride on top of walking belt guides at the outside edge of

treadles.

Tracking adjustment Belts are not required to be perfectly centered and are typically farther out in

the rear than they are in the front. This may vary depending on user’s stride.

If belt is tracking to one side far enough to cause rubbing of belt, follow the

“AdjustingtheWalkingBelts”procedure.

If problem persists Contact Customer Care for further assistance.
