Tension the belts of the bottom plate
Tension the toothed belt of the bottom plate by turning the belt
tensioner screw (see arrow) until it can still be easily turned by
180° with two fingers.
Caution:
The toothed belt must not be tensioned too strongly. If the belt
tensioner bends, the belt tension must be reduced under all
circumstances.
A method for more precise setting of the belt tension is found
in the chapter „Maintenance“.
Final inspection of the parallelism of the bottom plate and Y-plate
2x foot holder Insert the right and left foot holder between the bottom plate
and the Y-plate.
Turn the toothed belt of the bottom plate to adjust the height of
the Y-plate until the foot holders touch the Y-plate.
Both sides now have to have the same distances between the
foot holders and the Y-plate.
If this is not the case, the threaded pin at the pinion of
one
threaded spindle must be loosened again.
Then turn the threaded spindle until both foot holders are flush
with the Y-plate.
Then tighten the threaded pin again and remove the foot hold-
ers.
