For bias which can not be fixed automatically, try the following methods to fix
the belt, as picture shown:
If the belt tends to move to the right, you should turn
the belt adjustment screw on the right in clockwise
direction. We recommend you turn 1/4 turn each time
and check how it works. If the belt remains slanting to the
right ,then turn the belt adjustment screw on the left in
counterclockwise direction 1/4,as shown in the picture A.
If the belt tends to move to the left, then turn the belt
adjustment screw on the left in clockwise direction
for 1/4 turn. If the belt remains slanting to the left
,then turn the belt adjustment screw on the right in
counterclockwise direction for 1/4 turn, as shown in the
picture B.
After having been used for a period, the belt might be
slightly elongated, and slipping and halting might appear
when a person is running on it. When these phenomena
appear, you should secure the screws on both sides for
1/4 turn. If the belt is too tight just loosen the screw on
both sides for 1/4 turn, as shown in picturec.
