This document provides the visual installation procedure for the Hilti DST 10-CA and DST 20-CA diamond wire saws. It outlines the required anchor specifications, hole spacing, and the sequence for mounting the rail system to ensure safe and accurate operation.
Mounting and Anchoring
Proper anchoring is critical for the stability of the wire saw system. Use the following specifications for installation:

- Anchor Type: HKD-D M12x50.
- Hole Spacing (Top): 175mm horizontal by 170mm vertical.
- Hole Spacing (Bottom): 285mm horizontal by 290mm vertical.
Ensure the anchors are installed securely into the concrete surface before attempting to mount the rail bracket.
Rail Installation
Follow these steps to mount the rail system:
- Install the HKD-D M12x50 anchors according to the specified dimensions.
- Position the rail bracket over the installed anchors.
- Secure the bracket to the anchors using the provided hardware.
- Tighten the fasteners firmly to ensure the rail is rigid and stable.
Cutting Setup
Once the rail is mounted, proceed with the rail alignment and wire saw setup:

- Align the rail system according to the cutting path requirements.
- Follow the numbered sequence (5 through 9) as illustrated in the manual to position the saw components correctly.
- Verify that all locking mechanisms are engaged before starting the cutting operation.
