Page 13: Storage
Do not store for more than a brief period in areas that although roofed still allow free circulation of air from outside. Perform commissioning not later than 1 year after delivery (the dispatch from ZIMM is the relevant date). For other storage conditions and storage times: Consult ZIMM GmbH. -
Page 14: Installation
Safety clearance between moving and fixed parts is maintained. Lack of self-locking! Material damage to the entire system and the ZIMM Actuator due to lack of self-locking for spindles with ball screw drive KGT. Spring pressure brake FDB or brake motor provided. - Page 15 ZIMM Actuator 6 Installation CAUTION The system will run on! Material damage to the entire system and the ZIMM Actuator due to running on. • The run-on travel may increase after the running-in phase. If necessary provide a spring pressure brake FDB or brake motor.
- Page 16 ZIMM Actuator Fig. 6: Flatness, parallelism and angular accuracy 1. Set up the ZIMM Aktuator and ensure compliance with the installation accuracy, and ensure straight alignment of the spindle attachment (e.g. with precision machine spirit level). 2. Install the ZIMM Actuator with bolts, tighten the installation bolts.

Fig. 8: T version (bevel gear drive) Check the direction of rotation at installation. Fitting the couplings and connecting shafts The ZIMM Actuator to be connected must have been fully installed. The bevel gear drives must be installed where appropriate. CAUTION Moving parts! Injuries due to rotating parts. - Page 18 ZIMM Actuator 6 Installation Fig. 9: Installation of connecting shafts CAUTION Axial joining force! Damage to the roller bearings, circlips etc. Use a suitable fixture to draw the connecting parts together. Do not apply blows or impacts to the shaft extensions.

Page 22: Correcting The Alignment
If necessary, the alignment can be corrected without much trouble. Spindle and anti-rotation lock lubricated (for more information see section “7.2 Lubrication”, page 25) Fig. 18: Correctly aligned ZIMM Actuator Loosen the fastening screws on the gearbox housing and on the head. Fully retract the jack (1). -
