Residual risks when using the unit
There is danger that during operation a hydraulic hose bursts or a screw fasten-
ing leaks. This means oil can escape at high pressure.
Always wear your personal protective equipment for all work performed on the
unit (see section 2.4 "Personal protective equipment").
There is the danger that small particles are ejected at high speed from the ma-
chining area (e.g. because of tool breakage).
Always wear your personal protective equipment for all work performed on the
unit (see section 2.4 "Personal protective equipment").
If the unit machines busbars made of an impermissible material or from an ex-
cessively thick material, there is the risk of the tools becoming damaged and tool
parts splitting off.
Perform machining on materials only in accordance with the proper usage (see
section 3 "Proper usage") and the technical specifications (see section 4
"Technical specifications").

Proper usage
The "stationary busbar cutting unit CW 120-S" (Model No. 4055.710) is a single-
acting high-pressure hydraulic unit for clean cutting copper or aluminium bars
with a maximum width of 120 mm and a maximum height of 12 mm. The unit is
not suitable for cutting structural steels or tool steels. The electro-hydraulic pump
(Model No. 4055.720) with the associated foot-operated switch (Model No.
4055.712) must be used as the drive for the "stationary busbar cutting unit".
