General Notes on Maintenance

NOTICE

Misalignment due to loosening screws!

The P-611 is maintenance-free and achieves its positioning accuracy as a result of the optimal

alignment of mechanical components and piezo actuators. Loosened screws cause a loss in

positioning accuracy.



Loosen screws only when instructed in this manual.



not

open the P-611.

7.2

Cleaning the P611

NOTICE

Damage from ultrasonic cleaning!

Ultrasonic cleaning can damage the P-611.



not

do any ultrasonic cleaning.

Requirements



You have discharged the piezo actuators of the P-611 (p. 27).



You have disconnected the P-611 from the electronics.

Cleaning the P611



Clean the surfaces of the P-611 with a cloth dampened with a mild cleanser or

disinfectant (e.g., isopropyl alcohol).
