Grounding Instructions

This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for

electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding

conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and

grounded in accordance with all local codes and ordinances.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock.

Check with a qualied electrician or serviceman if you are in doubt as to whether the product is

properly grounded. Do not modify the plug provided with the product – if it will not t the outlet,

have a proper outlet installed by a qualied electrician.

If you connect the machine to an outlet with GFI (ground fault interrupt) or AFI (arc fault interrupt), machine operation can

cause the circuit to trip. This machine is for use on a nominal 120-V circuit, and has a grounding plug that looks like the

plug illustrated below. A temporary adapter that looks like the adapter illustrated may be used to connect this plug to a

2-pole receptacle as shown if a properly grounded outlet is not available.

The temporary adapter should be used only until a properly grounded outlet can be installed by a qualied electrician.

The tab for the grounding screw must be connected to a permanent ground such as a properly grounded outlet box cover.

Whenever the adapter is used, it must be held in place by a metal screw.

Emergency Stop Procedure

The Treadmill machine is equipped with a Safety Key that can prevent serious injury, as well as prevent children from

playing with and/or being injured on the machine. If the Safety Key is not correctly inserted into the Safety Key Port, the

belt will not operate.

!Always attach the Safety Key Clip to your clothing during your workout.

When you use the machine, only remove the Safety Key in an emergency. When the key is removed while

the machine is in operation, it will stop quickly, which could cause the loss of balance and possible injury.

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.

The Console will display “ + SAFETY KEY ”, or add Safety Key, for a Safety Key fault. The Treadmill machine will not start

a Workout, or will end and clear an active Workout, when the Safety Key is removed. Inspect the Safety Key and be sure

it is connected to the Console correctly.

Storage and Moving the Machine

The machine can be moved by one or more persons. Use caution when you move the machine. The

treadmill is heavy and can be awkward. Make sure that your own physical strength is capable of moving the

machine. Use a second person if necessary.

1. Remove the Safety Key.

WARNING! When this machine is not in operation, remove the Safety Key and keep out of the reach of children.

2. Make sure that the power switch is turned Off, and the power cord is disconnected.

Never lift the front of the machine for moving or transport. Rotating or moving parts can pinch, resulting in

personal injury.

3. You must fold the treadmill before you move it. Never move the treadmill if it is not folded.

4. Make sure that there is safe clearance around, on and above your treadmill. Make sure there is no object to spill or

cause blockage from the fully folded position.

Be sure there is adequate height clearance for the raised deck.

5. Press and hold the plastic deck release handle (5a) under the end of the right side rail. Using the support bar (5b)

found below the rear of the walking belt, lift the walking deck and continue to hold the deck handle for the rst part

of the fold process (0-15 degrees). Release the deck handle and lift the walking deck fully upward and engage the

hydraulic lift. Be sure that the hydraulic lift is correctly locked in place

Use proper safety precautions and lifting techniques. Bend your knees and elbows, keep your back straight

and pull up equally with both arms. Make sure that your own physical strength is capable of lifting the

walking deck until it engages the locking mechanism. Use a second person if necessary.

Do not use the walking belt or rear roller to lift the treadmill. These parts do not lock in place and can

abruptly move. Injury to you or damage to the machine can occur.

15°

6. Make sure that the locking mechanism is engaged. Carefully pull back on the walking deck and make sure that it does

not move. When you do this, keep clear of movement path in case the treadmill lock is not engaged.

Do not lean against the treadmill when it is folded. Do not put items on it that could cause it to become

unstable or fall.

Do not connect the power cord or try to operate the treadmill in the folded position.

7. Carefully tilt the base frame of the folded treadmill a small distance back on the transport wheels (5c) while grasping

the support bar (5b).

Do not use the Console, handlebars, or lifted walking deck to lift or move the treadmill. Damage to the

treadmill can occur.

Keep clear of the movement path of the lifted walking deck.

8. Roll the machine on the transport wheels (5c) to its new location.

Do not put objects where the walking deck would be if lowered.

NOTICE: Move the machine carefully so that it does not hit other objects. This can damage the Console operation.

9. Prior to use, refer to the “Unfolding the Machine” procedure in this manual.

Unfolding the Machine

1. Make sure there is sufcient space to lower the walking deck.

Keep a minimum clearance behind the machine of 79” (2 m) and 24” (0.6 m) on each side. This is the

recommended safe distance for access, movement and emergency dismounts from the machine.

Place the machine on a clean, hard, level surface, free from unwanted material or other objects that may

hamper your ability to move freely with a sufcient clear workout area. A rubber mat below the machine is

recommended to prevent electrostatic discharge and protect your oor.

Be sure that the workout space you are utilizing has adequate height clearance, taking into consideration

the height of the user and the maximum incline of the deck.

2. Make sure there is no object on or around the treadmill to spill or cause blockage from the fully unfolded position.

3. Move to the right side of the machine. Press and hold the plastic deck release handle (5a) under the end of the right

side rail. While grasping the support bar (5b), release the deck handle.

Keep clear of the movement path of the walking deck.

4. The hydraulic lift is set up to drop lightly. Hold onto the walking deck until approximately 2/3 of the movement down.

Make sure that you use proper lifting technique; bend your knees and keep your back straight. The walking deck can

possibly drop quickly in the last part of the movement.

Leveling the Machine

The machine needs to be leveled if your workout area is uneven. To adjust:

1. Place the machine in your workout area.

2. Adjust the levelers until they all contact the oor.

Do not adjust the levelers to such a height that they detach or unscrew from the machine. Injury to you or

damage to the machine can occur.

3. Adjust until the machine is level.

Make sure the machine is level and stable before you exercise.

Treadmill Belt

Your treadmill comes equipped with a durable, high quality walking belt designed to provide many hours of reliable ser-

vice. The walking belt on a treadmill that has not been operated for a length of time, either in factory packaging or after

assembly, can exhibit a “thumping” noise when started. This is due to the belt taking on the curve of the front and rear roll-

ers. This is a common occurrence and does not indicate a problem with your machine. After the treadmill has been used

for a short period of time the thumping noise will discontinue. The amount of time will vary depending on the temperature

and humidity of the environment where the treadmill is placed.
