Troubleshooting: A lot of play on the turntable
If, under any circumstances, grub screws on the turntable should come loose, you will notice a rather large play
on the turntable if it can be turned several degrees without much effort, noticeably more than if there is a pure
gear backlash (see point V.). To eliminate this, the following steps are necessary:
1.
Loosen four cylinder screws DIN 912 - M3x45 (
Fig.
6) on the motor cover.
Fig. 6
2.
tilt the motor cover in the direction of the attached logo.
3.
Carefully remove the logo from the motor cover (still sticks sufficiently well afterwards).
4.
looking inwards, the worm wheel (
Fig.
7) becomes visible on the turntable.

5.
three grub screws DIN 916 - M3x5 are attached to the circumference, each distributed at 120°.
6.
three spanner surfaces distributed over 120° are also milled on the turntable shaft. One of them points
exactly in the direction of the clearance on the top of the turntable (
Fig.
7).
7.
Align the worm wheel with a grub screw for franking and tighten hand-tight.
8.
Turn the motor further with the handwheel and hand-tighten the next two grub screws.
9.
Then tighten all three grub screws one after the other to a maximum of 1.0Nm.
