Intended use

Worm gear screw jacks are incomplete machines and are intended for installation in complete machines or
for assembly with several machines into a system.
They are drive elements that are employed for converting rotational movement into longitudinal movement
and for reducing speed or converting torque.
The drive systems may only be used for the designated purpose.
They may be used only under the application conditions specified in the operating instructions, in the
technical documentation or in the order confirmation.
Operation outside the respective performance limitations / ambient conditions is not permitted.
Not suitable for use in explosive-atmosphere zones.
Not suitable for use in aggressive environments, if not constructed especially for these applications.
Modifications to the screw jacks as well as the attachment of additional devices are only permitted with our
express and written authorisation.
Pay attention to the technical data and functional description!
If stated in the order confirmation, the worm gear screw jacks with corresponding additional supplementary
equipment comply with the requirements of various standards and guidelines:

complete system. The information in our operating instructions must be integrated in the instructions for the
complete machine.
Required prototype tests (experts' examinations) need to be carried out under the responsibility of the
manufacturer of the complete machine.
1.2

Worm gear screw jacks in accordance with ATEX guideline 2014/34/EC

are suited as components (2014/34/EC item 1 (3) for installation in machines for use in explosive-
atmosphere zones as indicated by the ATEX marking.
For the ignition source analysis, the ATEX checklist must be filled out completely and submitted (www.pfaff-
silberblau.com).
The manufacturer of the complete system checks that the product in combination with the complete machine
is ATEX conform, and is responsible for conducting the ignition source analysis for the complete system.
The information in our operating instructions must be integrated in the instructions for the complete machine.
The suitability of the ATEX components for use in the existing Ex zone must be checked or assessed in
accordance with the ATEX marking, the order confirmation, conformity declaration and type plate.
