1. Align screw and screw jacks (e.g. with a spirit level, 0.3 mm/m), then screw tight, and anchor if necessary.

2. Make sure the screw is parallel to the on-site guides.

3. Avoid distortions. The worm shaft should turn easily and evenly throughout the entire lift height.

4. Clean screw and grease along the entire lift height.

5. For HSE and SHE with oil lubrication:

Pull tapered pin at the venting or insert pressure venting screw at the highest point.

Check lubrication level and top up if necessary.

6. For SHE with grease lubrication: Lubricate the gear using the grease gun at the lubrication nipple. Housing

needs to be filled completely with grease.

For HSE for the ATEX area, insert the pressure bleed plug at the highest

point for venting.

For multi-screw units

7. Check turning directions of all screw jacks.

8. Even out uneven support surfaces (use metal shims).

9. Move the screws/travelling nuts to the same height before depositing, aligning and fastening the

load.

To even out alignment errors between the individual elements, use rotationally elastic couplings,

rotationally elastic propeller shafts or cardan shafts.

Monitor the lubrication film and the screw temperature during the run-in phase. If there is rapid lubrication

consumption and excessive temperature despite compliance with the duty cycles and the maximum

capacity specifications, this indicates impermissible lateral forces.
