Grounding Instructions (for a 120V AC system )
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.

Earthing Instructions (for a 220-240V AC system )
This product must be electrically earthed. If a malfunction occurs, correct earthing decreases the risk of electric shock.
The power cord is equipped with an equipment-earthing conductor, and must be connected to an outlet that is properly
installed and earthed.
The electrical wiring must comply with all applicable local and provincial standards and
requirements. Incorrect connection of the equipment-earthing conductor can result in a risk of
electric shock. Consult a licensed electrician if you are not sure that the machine is correctly
earthed. Do not change the plug on the machine – if it does not t the outlet, have a correct outlet
installed by a licensed electrician.
If you connect the machine to an outlet with RCBO (Residual-Current circuit Breaker with Overload protection), machine
operation can cause the circuit to trip. A Surge Protector Device is recommended to protect the machine.
!If a Surge Protector Device (SPD) is used with this machine, be sure that it matches the power rating of this
equipment (220-240V AC). Do not connect other appliances or devices to the surge protector in combination
with this machine.
Make sure that the product is connected to an outlet having the same conguration as the plug. Use the
appropriate adapter supplied with this product.

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
service. 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 rollers. 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.

MAINTENANCE

13
NOTICE: To prevent damage to the nish of the machine or Console, do not clean with a petroleum based solvent.
Do not apply too much moisture to the Console.
Adjusting the Belt Tension
If the walking belt starts to slip during use, it is necessary to adjust the tension. Your treadmill has tension bolts at the rear
of the treadmill.
1. Before you adjust the belt tension, start the treadmill by pushing the START button.
Be sure not to touch the walking belt or step on the power cord. Keep bystanders and children away from
the product you are servicing at all times.
2. Use a 6 mm hex key to turn the right and left belt adjustment bolts clockwise a 1/2 turn, rst one bolt and then the
other bolt until the belt does not slip.
3. After you adjust each side the 1/2 turn, do a test to see if the belt stopped slipping. If the belt still slips, do steps 2 and
3 again.
If you turn one side more than the other, the belt will move away from that side of the treadmill and may need realignment.
NOTICE: Too much tension on the belt causes unnecessary friction and wears the belt, motor and electronics.
4. Push PAUSE/STOP twice to stop the walking belt and end the Quick Start workout.
Aligning the Walking Belt
The walking belt should be centered on your treadmill at all
times. Running style and a non-level surface can cause the
belt to move o󰀨 center. Minor adjustments to the 2 bolts at the
rear of the treadmill are necessary when the belt is o󰀨 center.
1. Push the START button to start the walking belt.
Be sure not to touch the walking belt or step on the
power cord. Keep bystanders and children away
from the product you are servicing at all times.
2. Stand at the rear of the treadmill to see which direction
the belt moves.
3. If the belt moves to the left, turn the left belt adjustment
bolt 1/4 turn clockwise and the right belt adjustment bolt
1/4 turn counterclockwise.
If the belt moves to the right, turn the left adjustment bolt
1/4 turn counterclockwise and the right adjustment bolt
1/4 turn clockwise.
4. Monitor the path of the belt for approximately 2 minutes. Continue to adjust the bolts until the walking belt is centered.
5. Push PAUSE/STOP twice to stop the walking belt and end the Quick Start workout.
Lubricating the Walking Belt
Your treadmill is equipped with a low maintenance deck and belt system. The Walking Belt is pre-lubricated. Belt friction
can a󰀨ect the function and life of the machine. Lubricate the belt every 3 months or every 25 hours of use, whichever
comes rst. Even if the treadmill is not in use, silicone will dissipate and the belt will dry out. For the best results, lubricate
the deck periodically with a silicone lubricant using the following instructions:
1. Turn o󰀨 the power to the machine with the power switch.
2. Unplug the treadmill fully from the wall outlet, and remove the power cord from the machine.

To reduce the risk of electrical shock, always unplug the power cord and wait 5 minutes before
cleaning, maintaining or repairing this machine. Place the power cord in a secure location.
3. Inspect the surface material below the Treadmill. If the surface material is di󰀩cult to clean or could be damaged by
silicone lubricant, place absorbent material (such as cardboard or newspaper) below the length of the Walking Deck.
4. Apply a few drops of the lubricant on the deck below the belt. Carefully lift the belt and apply a few drops of the lubri-
cant the entire width of the belt. A very thin layer of silicone lubricant on the entire deck below the belt is desired.
NOTICE: Always use a 100% pure silicone lubricant. Do not use a degreaser like WD-40® as this could seriously
impact performance. We can recommend that you use the following:
• 100% pure silicone, available at most hardware and auto parts stores.
• Lube-N-Walk® Treadmill Lubrication Kit, available from your local specialty tness dealer or Nautilus, Inc.
Silicone lubricant is not intended for human consumption. Keep out of reach of children. Store in a safe
place.
5. Manually rotate the belt 1/2 of the length of the belt and apply lubricant again.
If you used spray lubricant, wait 5 minutes before turning on power to the machine to allow the aerosol to
dissipate.
6. Connect the power cord back into the machine and then into the wall outlet.
7. Turn on the power to the machine with the power switch.
8. Stay to one side of your machine and start the belt at the slowest speed. Let the belt operate for approximately 15
seconds.
Be sure not to touch the walking belt or step on the power cord. Keep bystanders and children away from
the product you are servicing at all times.
9. Switch o󰀨 your machine.
10. Take care to clean up any excess lubricant from the deck.
To decrease the possibility of slipping, be sure the deck area is free from grease or oil. Clean o󰀨 any excess
oil from the machine surfaces.
As you use your tness machine, the Console will show “LUBRICATE BELT” followed by “REVIEW USER MANUAL” at
set times. This is only a reminder and should be added to your inspection schedule. Only apply lubricant as necessary.
Push any button to accept the reminder.

About Noises:
A “thumping” noise is
normal for a new machine
or new Walking Belt, and
will go away with with use.
This is caused by the Belt
conforming to the Rollers
and having a “flat spot” on
it.
If the noise only happens
when the user is walking
on the machine, have a
2nd user walk on the
machine while the user
locates the source of the
noise.
