Tool-Control and Likufix.
What is Tool Control?
Tool Control is an additional electro-hydraulic function which makes working with hydraulic add-
on parts very convenient. Up to ten combinations of oil fl ows and pressures can be programmed
with the name of the tool and selected directly from the display. With the help of Tool Control, the
operator can select the parameters for the hydraulic tool he wishes to use with a simple press of
a button – no elaborate readjustment needed when it comes to a tool change.
What is LIKUFIX?
Likufi x is a hydraulic quick-change system combined with an automatic hydraulic coupling
device designed for quick, reliable changing of mechanical and hydraulic add-on tools,
directly from the cab. Likufi x is the ideal supplement to Tool Control. The combination of
Likufi x and Tool Control makes it possible to change hydraulic add-
on tools easily – without even leaving the cab.
The technical advantages:
• Fully automatic play compensation
• Tight connection between the hydraulic circuits thanks to the
hydro-mechanical compensation system
• More than 25 years experience in fully-automatic
coupling systems
• Reliable system with long service life
The convenience advantage:
• Reliable hydraulic connection free of oil leaks
• Low operating and maintenance costs
• Add-on parts can be changed from the cab
The economic advantage:
• Easy equipping of existing hydraulic excavators
• Hydraulic add-on parts changed in a matter of seconds – meaning
better machine utilisation with different applications on the same unit
• Major time savings in comparison with hydraulic-hose changes
• Low operating and maintenance costs with maximum productivity
• Carefully selected use of the add-on parts for long tool service life
