MAINTENANCE
Proper maintenance is very important to ensure your treadmill is always in top working condition.
Improper maintenance could cause damage or shorten the life of your treadmill and exceed the
LIMITED WARRANTY coverage.
1. Important: Never use abrasives or solvents to clean the treadmill. To prevent damage to the
computer, keep liquids away and keep it out of direct sunlight.
2. Inspect and tighten all parts of the treadmill regularly. Replace any worn parts immediately
CLEANING:
Routine cleaning of your treadmill will extend the product’s life.
1. Warning: To prevent electrical shock, be sure the power to the treadmill is OFF and the power cord is
unplugged from the wall electrical outlet before attempting any cleaning or maintenance.
2. Important: Never use abrasives or solvents to clean the treadmill. To prevent damage to the computer, keep
liquids away and keep it out of direct sunlight.
3. After each workout: Wipe off the console and other treadmill surfaces with a clean, water dampened
soft cloth to remove excess perspiration
4. Weekly: Use of a treadmill mat is recommended for ease of cleaning. Dirt from your shoes contacts the belt
and eventually makes it to underneath the treadmill. Vacuum the underneath treadmill once a
week.
BELT ADJUSTMENT:
Belt adjustment and tension performs two functions: adjustment for tension and centering. The running
belt has been adjusted properly at the factory. However transportation, uneven flooring or other
unpredicted reasons could cause the belt to shift off center resulting in the belt rubbing with the plastic side
rail or end caps and possibly causing damage. To adjust the belt back to it proper position please follows
the directions below:
1. Walking belt has shifted to the left:
First unplug the power cord from the surge protector. Using the hex key provided, turn the left rear
roller adjustment bolt 1/4 turn in the clockwise direction. Plug the power cord back into the surge
protector and run the treadmill at 2.5 mph. You should see the belt start to correct itself, moving back
towards the center. Repeat the above procedure until the walking belt is centered. It may be necessary
to set walking belt tension once you have completed this procedure if the belt feels like it is slipping
while walking. Refer below to the “Walking belt slipping” instructions.
2. Walking belt has shifted to the right:
First unplug the power cord from the surge protector. Using the hex key provided, turn the right rear
roller adjustment bolt 1/4 turn in the clockwise direction. Plug the power cord back into the surge
protector and run the treadmill at 2.5 mph. You should see the belt start to correct itself, moving back

- 18 -
towards the center. Repeat the above procedure until the walking belt is centered. It may be necessary
to set walking belt tension once you have completed this procedure if the belt feels like it is slipping
while walking. Refer below to the “Walking belt slipping” instructions.
3. Walking belt is slipping:
First unplug the power cord from the surge protector. Using the hex key provided, turn both the left and
right rear roller adjustment bolts the same distance, usually a 1/4 turn in the clockwise direction. Plug
the power cord back into the surge protector and run the treadmill at 2.5 mph. You should now walk on
the belt to determine if the belt is still slipping. Repeat the above procedure until the walking belt is not
slipping. The tension should be just tight enough not to slip.
WARNING! Do not over tighten rollers! This will cause premature roller bearing failure!
Right and leftAllen bolts are located at the rear of the treadmill.
DECK LUBRICATION:
The walking belt has been pre-lubricated at the factory. However, it is recommended that the walking board be
checked periodically for lubrication to ensure optimal treadmill performance.
Every 3 months of operation lift the sides of the walking belt and feel the top surface of the walking board as far
as you can reach. If you feel signs of silicone, no further lubrication is required. If it feels dry to the touch, follow
the instructions below.
Please use Lube ‘N Walk, or a non petroleum based silicone such as “Napa 8300” (available at most stores).
TO APPLY LUBRICANT TO THE WALKING BELT
1 Position the walking belt so that the seam is located on top and in center of the walking board.
2 Insert the spray nozzle into the spray head of the lubricant can.
3 While lifting the side of the walking belt, position the spray nozzle between the walking belt and the board
approxinateluy6” from the front of the treadmill. Apply the silicone spray to the walking board, moving from
the front of the treadmill to the rear. Repeat this on the other side of the belt. Spray approximately 4
seconds on each side.
4 Allow the silicone to “set” for 1 minute before using the treadmill.

REMARK: When the treadmill is over load by any case, for the using safety
the fuse will be broken and the power will be cut off . Change a
new fuse and start again.
