Why does the diamond wire jump about and vibrate strongly on my Hilti DS WS15?

  jonathan83Aug 20, 2025
  If the diamond wire jumps about and vibrates strongly on your Hilti Saw, it could be due to several reasons. First, ensure there's sufficient tension on the wire by adjusting the air pressure regulation. If the guide pulleys are too far apart, mount additional pulley stands to reduce the free length of the wire. Also, consider fitting a shorter diamond wire or positioning the drive unit closer to the object you're cutting.

Why does the diamond wire wear too quickly on my Hilti DS WS15 Saw?
- J
  Joshua ReynoldsAug 22, 2025
  If the diamond wire wears too quickly on your Hilti Saw, there are several potential causes. First, check that the drive speed and wire cutting speed aren't too low; increase them if necessary. Ensure adequate cooling of the diamond wire by setting up more water nozzles at the cutting face. If the wire cutting length is too short, increase the length of contact between the wire and the concrete. Reduce wire tension if it's too high relative to the length of the cut by adjusting the air pressure regulation valve. If you're cutting a very abrasive material, select a different diamond wire specification. Finally, ensure the diamond wire always runs in the same, specified direction.

What to do if the DSWS15 Hilti DS WS15 doesn't start, and the green 'ready for operation' lamp lights together with the red 'error' lamp?
- T
  Timothy VangAug 25, 2025
  If the DSWS15 Hilti Saw doesn't start and the green “ready for operation” lamp lights together with the red “error” lamp, it could be due to several reasons. Check if the power cable or control cable from the drive is connected to the control unit and connect the cables if they are not. Ensure the protective cover is fitted on the machine. If the motors are too hot, use more or colder cooling water. Also, ensure that you do not work above 30 A if the current converter is overloaded. You can also check the filter in the base of the control unit to ensure there is a flow of air at the top opening on the control unit. As a last resort, you can try resetting the converter by switching off at the main switch and waiting approximately 1 minute before switching on again.

Why does the diamond wire slip on the drive wheels of my Hilti Saw?
- T
  Trevor BoydAug 26, 2025
  If the diamond wire slips on the drive wheels of your Hilti Saw, it could be due to insufficient tension on the diamond wire. Increase the tension by adjusting the air pressure regulation valve. Alternatively, the rubber tire on the drive wheel may be excessively worn, in which case you should replace the drive wheel.

How to troubleshoot the DSWS15 Hilti Saw when it cannot start movement of the wire?
- C
  christinaterryAug 27, 2025
  If the DSWS15 Hilti Saw cannot start movement of the wire, it could be due to several reasons. If the edges of the concrete are too sharp, use a Hilti combihammer to round the edges and pull the diamond wire back and forward by hand before starting. If a new diamond wire sticks in the kerf cut by a worn wire, complete the cut with the worn wire. If the length of contact between the diamond wire and the concrete is excessive, drill a hole through which the new wire can be threaded. If the tension on the diamond wire is too high, reduce wire tension by adjusting the air pressure regulation valve.

What to do if the DSWS15 Hilti Saw doesn't start but the green “ready for operation” lamp lights?

  Sabrina ClarkAug 29, 2025
  If the DSWS15 Hilti Saw doesn't start, but the green “ready for operation” lamp lights, it's likely that the EMERGENCY STOP button is pressed in. To resolve this, simply release the EMERGENCY STOP button.

What causes the diamond wire to pull out of the crimped connector on my Hilti Saw?
- B
  billyforbesAug 31, 2025
  If the diamond wire pulls out of the crimped connector on your Hilti Saw, several factors could be at play. Ensure the crimping pliers are correctly adjusted. Apply sufficient pressure to the crimping pliers, with a minimum crimping pressure of 7 t (Hilti crimping pliers = 8 t). Check the crimping jaws for wear or damage and replace if necessary. Also, make sure the wire is pushed far enough into the connector, cut cleanly, and in accordance with instructions.

Why does the diamond wire vibrate very strongly at a high frequency on my Hilti Saw?
- K
  Kathleen MaySep 2, 2025
  If the diamond wire vibrates very strongly at a high frequency on your Hilti Saw, it could be due to a couple of reasons. First, check the tension on the wire and reduce it by adjusting the air pressure regulation if it's too high. Also, ensure the saw is running at the correct speed and adjust it accordingly.

What causes the diamond wire to collapse on my Hilti DS WS15?
- H
  henry54Sep 4, 2025
  If the diamond wire collapses on your Hilti Saw, ensure that the diamond wire is adequately cooled by ensuring sufficient water reaches the cutting face. If the diamond wire becomes stuck in the kerf and stalls during sawing, steel wedges must be used to prevent movement of the concrete sections. Also, ensure that loose fragments or aggregates must be removed from the kerf.

Why does the wire jump off the drive wheels when starting my Hilti DS WS15?
- J
  joel71Sep 6, 2025
  If the diamond wire jumps off the drive wheels when starting your Hilti Saw, it's likely that the starting lock was not used. To resolve this, use the starting lock by positioning and locking the clamping piece against the air cylinder.
