6 Positioning the toothed belt wheels
The two toothed belt wheels must be positioned one on top of the other
such that the toothed belt can run correctly. In machines with normal
lengths, the winder wheel is directly next to the upper toothed belt wheel
and determines its alignment. In long arm machines, the winder wheel is
fastened farther away in the center of the arm.
Order
• Always check the position of the other toothed belt wheel after making a
change on either of the toothed belt wheels.
The position of the upper toothed belt wheel is defined by the distance to
the winder wheel.
Therefore, you must first align the upper toothed belt wheel on the winder
wheel and then align the lower toothed belt such that the toothed belt runs
correctly over both wheels.
6.1 Setting the upper toothed belt wheel
Proper setting
The 2 threaded pins for the upper toothed belt wheel are seated flush on
the flat.
The distance between the winder wheel and the upper toothed belt wheel
is 0.8 mm.
Cover
• Arm cover ( p. 11)
WARNING
Risk of injury from moving parts!
Crushing possible.
Switch off the machine before you check and set
the upper toothed belt wheel.
