● If it is biased to the right, use a hex wrench to turn the right
screw 1/4 turn clockwise;
● If the running belt is still not in the middle, repeat the above
action until it is adjusted to the middle.
After adjusting the running belt to the middle, adjust the speed

the smooth running condition. If there is any deviation, repeat the
adjustment step.
Caveat! Do not overtighten the rollers! This will result in permanent
