Star trac Pro Treadmill AC 7600 – 7700 – How to adjust the running belt tension – How to access Maintenance mode – Auto calibration

Star trac Pro Tread AC 7600 – 7700
RUNNING BELT RETENSION PROCEDURE 
Step 1: Release tension of running belt by unscrewing the tension screws until the roller touches the finger-guard. The belt should be completely relaxed.
(Note: This applies to both left & right fingerguards.)
Step 2: Apply a piece of masking tape on the edge of the running belt on both sides.
Step 3: Draw a line on each piece of masking tape aligned with the edge of the deck.
(Note: Be careful not to move the belt or roller while drawing the lines.)
Step 4: Check to make sure that both lines are aligned with the edge of the deck at the same point.
Step 5: Using a ruler or tape measure, draw a line on each piece of tape parallel to each first line at a distance of 3/8” (9.5mm) from each first line.
Step 6: You are now ready to begin tensioning the belt. Before beginning, make sure the line on each piece of tape closest to the tail roller is aligned with the edge of the deck on each side.
Step 6: Using the 1/4" Allen wrench begin tightening the tensioning screws (see Fig 1). You will tighten (or stretch) the run belt until the forward lines on the tape are aligned with the edge of the deck.
Be careful to ensure the Tail Roller does not turn while you are stretching the belt. If the Tail Roller turns while you are stretching the belt, start the procedure over. If the Tail Roller turns while stretching the belt you will not obtain proper tension.
When finished, remove the tape from the running belt.
