Mount the support 1 between the spars 3 with
the screws 2.
Swing the support 1 up. The hole in the support
plate 6 must fit over the seating pin 5 located
on the bottom of the angle 4.
Align the guide rods 8 horizontally in the
longitudinal (direction of the carriage transport)
as well as the transverse direction. Use a water
level.
Tighten the clamp levers 9 and the nuts 7 in the
appropriate position.

Insert the belt tensioner 11 and tighten the
self-locking nut 10 so that at the middle of the
frame length S the timing belt can be shifted
from its straight path under a test load of
Fv = 2500g so far that the upper half of the belt
just barely touches the lower half of the belt
under the test load. See sketch.
Testing can be conducted with a spring balance.
Unnecessary high tensioning reduces the life of
the timing belt and causes running noise.
A too low tensioning can lead to the belt teeth
not gripping properly in the sprocket teeth or
that the belt jumps under load.
