2. Set the Z-axis counter value to -19750, and then loosen the coupling and push the Z-

axis up/down lever cam follower lightly against the syringe arm (Top of the syringe

pusher). Then tighten the four coupling bolts equally. (Tightening torque wrench

0.4Nm).

(It is better to turn the servo ON or use the ABS to stop the Z-axis counter moving

during this measurement.)

3. The following screen displays after performing MT reset. Proceed to the upper limit

position measurement.
