➠ Move the x-slide against the stop on the motor side.
➠ Measure the belt tension on the side of the placement head.
➠ Center the measuring pin of the belt tension measuring device, 208 mm away from the
deflection pulley of the open ended toothed belt, as close as possible to the belt.

➠ Strike the toothed belt, to reach a stimulation of vibration on the open ended toothed belt.
➠ If the frequency of the belt tension does not reach a value of 53 Hz +1 / -3 Hz, you must tension
the belt with the help of the head screw (3) on the belt key of the x-axis.
NOTE
Repeat these instructions, until the belt tension is correct.

NOTE
The distance between both proximity switches of the x- and y- axis, is set to 0.2 mm.
(Measured from the operational plane).
