Why is there a leak on the handhold of my Lukas Cutter?
- A
  Andrea BushAug 20, 2025
  A leak on the handhold can occur due to a sudden load increase. To resolve this, secure the load and move it elsewhere. Alternatively, apply the device at a point where the load is lighter, use supporting equipment, or reduce the pressure in the device. If the leak persists, deactivate the device and contact an authorized dealer or LUKAS directly. Other causes include hoses in the handhold not tightened (tighten them) or supply and return connection of the mono-coupling sleeve inverted (correctly reconnect the hoses).

What to do if hose lines cannot be coupled with the Lukas S 3 Cutter quick-connect system?

  If hose lines cannot be coupled with the quick-connect system, it could be because the system is pressurized. In this case, relieve the pump. Another reason may be a defective coupling, which must be replaced immediately.

What to do if the Lukas S 3 Cutter mono-coupling system hose lines cannot be coupled?
- D
  David HillAug 25, 2025
  If hose lines cannot be coupled in the mono-coupling system, the pressure may be too high, possibly due to high ambient temperature. To fix this, set the hydraulic pump to unpressurized circulation. Another potential cause is a defective coupling, which requires immediate replacement.

Why is there a leak at the couplings of my Lukas S 3 with the quick-connect system?
- A
  Ashley SanchezAug 30, 2025
  If there's a leak at the couplings in the quick-connect system, the coupling is likely defective and needs immediate replacement.

Why is there damage on the surface of the hydraulic hoses of my Lukas S 3 Cutter?
- T
  Taylor GomezSep 1, 2025
  Damage on the surface of the hydraulic hoses can be caused by mechanical damage or contact with aggressive media. The solution is to replace the hoses.

What to do if Lukas Cutter mono-coupling system hose lines frequently cannot be coupled?
- R
  Raymond Kim DVMSep 3, 2025
  If hose lines frequently cannot be coupled, it may be because the hydraulic fluid is not adapted to the application situation, in which case it must be replaced. It could also be due to a defective coupling, which requires immediate replacement.

Why is there a leak on the handhold, especially when using the Lukas S 3 Cutter mono-coupling system?
- E
  edwardsshellySep 6, 2025
  If there's a leak on the handhold, especially with the mono-coupling system, it could be due to the hose connection to the coupling being interchanged. Correctly reconnect the hoses to the coupling to resolve this. Another cause could be a disabled return hose. Disconnect the return hose from the coupling, clean it, and reconnect it.

What to do if my Lukas S 3 device doesn’t perform at its given power?
- D
  Danielle MartinezSep 7, 2025
  If the device isn’t performing at its given power, it could be due to too little hydraulic fluid in the pump. You should top up the hydraulic fluid and deaerate the system.
