The running belt is properly adjusted at the factory but may loosen or change over time. It is important to
properly adjust the running belt so it has the right tension and is centered on the deck, without drifting to
one side.
RUNNING BELT TENSION
To check the running belt tension, pull up on the running belt in the middle of the running surface, and the
running belt should lift off the running deck between 2-3 inches. If the running belt is too tight, this will
negatively affect the motor’s performance and also create more friction between the roller and running belt.
When the running belt is too loose, it may not move smoothly with the motor.
RUNNING BELT CENTERING
To check the centering of the running belt, set the Incline to 0 and set the Speed to 3.0 mph. Watch the
belt to see if it moves all the way to the left or right on the running deck. If properly centered, the belt
should be centered on the running deck and the side platforms. If the running belt is not properly centered,
this will cause premature running belt failure.
To adjust the running belt tension or centering, use the included Allen wrench and use this table to know
which adjustment screw to turn. Repeat the steps given in the table until it is properly adjusted.
