User Guide
Install Swift Leveller XL in Six Practical Steps

The Swift Leveller XL is designed for difficult access areas, larger outdoor buildings, and higher void levelling. It must always be concreted in place, and the sequence below covers the core installation process from preparation to final adjustment.

1
Prepare the area and support the base frame at the estimated height

Clear and prepare the area, then put the base frame at the estimated height using packers.

2
Mark the frame for the U-channel installation points

Mark the frame at equal intervals to identify where the U-channels will be installed.

3
Dig the installation holes to the required depth

Using the markings as a guide, dig holes into the ground to a depth of at least 500mm.

4
Insert the base plates and fix the U-channels under the frame

Insert the base plates into the ground, then position the U-channels under the frame and screw them into place.

5
Ensure the bases are straight and set them in concrete

Ensure the bases are straight and level, then set them in place with concrete for secure long-term support.

6
Adjust the heads and secure the frame at the required height

Adjust each head to the required height and tighten each nut to secure the frame. Check with a spirit level and adjust as needed.
