damage the unit and cause severe injuries. Consequently, observe all the following safety instructions
and contact our service team should you have any questions.
caution...
!
• when handling hydraulic oil. The oil can become very hot after longer operation.
There is a risk of injury!
• Long busbars can swing backwards quickly and unexpectedly when being bent.
Ensure that nobody is present in the work area. Risk of injury!
• To extend the service life of the unit, the hydraulic cylinder should not travel
to the limit stop under full pressure.
• Risk of environmental contamination! Collect any escaped hydraulic oil and
prevent it from entering the sewer system or the surface and ground water.
!
always...
• machine busbars made of copper or
aluminium.
• position busbars centred and perpendicular
in the unit.
• remove objects and foreign bodies from the
work area.
• position busbars centred to the load piston
so that the bending die does not skew.
• observe the maximum permitted dimensions
of the workpieces.
• support long busbars appropriately to prevent
them from tilting.
• inspect electrical and hydraulic connection
lines for damage before deploying the unit.
• use the prescribed hydraulic pump.
• ensure the secure footing of the unit.
• observe the information contained in the
