6. Conversely, if the belt is in the right red zone, turn the right belt adjustment nut
clockwise 1/4 turn, then turn the left adjustment bolt counterclockwise 1/4 turn.
Then let the treadmill run at least 30 seconds, check the position of the belt in
the color gauge. If it stills has not returned to the green safety zone, repeat with
another 1/4 turn until the belt has return to the middle of the green area. Do not
turn adjusting bolt more than 1/4 turn at a time.
7. When the belt is back in the green "safety zone", you can continue your regular
use of the treadmill. Slowly increase the speed of the unit to 5.5 MPH (9 KPH),
and let it run for at least 45 seconds.
8. When you are using the treadmill, if you feel a pause in the belt with each foot
plant the belt is too loose. Stop the machine, adjust both rear roller bolts
clockwise 1/2 turn at a time. Try the machine again, then check the result, if more
adjusting is required, give both adjusting bolts another slight turn. Do not adjust
over 2 fullturns.
9. If the belt is too tight, this will adversely effect the life of the unit.
10. To check the correct tension of the belt, grab the belt in the middle, and lift up
about 15m/m (5/8") or 3-5 kg (6.6-11 pounds) of force (see Fig.7,7-1,7-2).
11. If there is too loose, you can tighten the belt by adjust both rear roller bolts
clockwise 1/2 turn at a time. Conversely, if the belt is too tight, adjust both rear
roller bolts counterclockwise 1/2 turn at a time (see Fig.7-3).
