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 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 left Allen 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).
TOAPPLY LUBRICANT TO THE WALKING BELT
1Position the walking belt so that the seam is located on top and in center of the walking board.
2Insert the spray nozzle into the spray head of the lubricant can.
3While 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.
4Allow 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.
