MAINTENANCE

• Warning:  

To prevent electrical shock, be certain the treadmill is turned off and unplugged for cleaning or 
 routine maintenance.

• 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.

• After each workout:  

Wipe off the console and other treadmill surfaces with a clean, water dampened soft cloth to remove 
excess perspiration.

• 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 underneath the treadmill once a week.

• BELT ADJUSTMENT

You may need to adjust the running belt during the first few weeks of use. All running belts are pro-
perly set at the factory. It may stretch or be off-center after use. Stretching is normal during the bre-
ak-in period.

ADJUST THE BELT TENSION

If the running belt feels as though it is “slipping” or hesitating when you plant your foot during a run, 
the tension on the running belt may have to be increased.

TO INCREASE THE RUNNING BELT TENSION:

A)  Place 6MM inner hexagon spanner on the left belt tension bolt located inside the rear end caps. 

Turn the inner hexagon spanner clockwise 1/8 turn to draw the rear roller and increase the belt 
tension.

B)  Repeat STEP A for the right belt tension bolt. You must be sure to turn both bolts the same num-

ber of turns, so the rear roller will stay square relative to the frame.

C) Repeat STEP A and STEP B until the slipping is eliminated.
D)  be careful not to tighten the running belt tension too much as you can create excessive pressure 

on the front and rear roller bearing that will result in bearing noise from the front and rear rollers.

TO DECREASE THE TENSION ON THE RUNNING BELT, TURN BOTH BOLTS COUNTER CLOCKWISE 
EVENELY.
