Instructions

First slide the guide carriage approx. into the middle of the guide rail.
Place the undertable on the Y-plate and attach the toothed belt to the
top of the motor knurl.
Now place the toothed belt below over the ball bearings of the belt
tensioner (upper arrow in the gure). This must be completely re-
laxed.
Tension the toothed belt slightly by turning the M4 cylinder head
screw in the belt tensioner basic body (lower arrow in the gure).
Attach the undertable to the guide carriage of the Y-plate using the 4
countersunk screws in the 4 centre holes.
Make sure that you really get all 4 holes on the guide carriage.
Apply a threadlocker varnish to the screws.
Tighten the screws slightly.
To check whether the undertable is mounted straight, set the com-
plete Y-plate upright and hold the undertable in place.
The edge on which the belt tensioner is located must be at the bottom
and supported on a straight surface.
Carefully lower the undertable. If it is not completely in contact with
the surface such as the Y-plate, loosen the 4 countersunk screws and
readjust the undertable.
Then tighten the screws crosswise.
Finally tighten the toothed belt correctly.
To do this, turn the M4 cylinder head screw in the belt tensioner basic
body again until it can be easily turned by 180° with two ngers.
