Operation
Maintenance
The two-hand control device only protects the machine operator. Do not let anyone else come near
when cutting.
Periodically check correct operation of the two-hand control device. Pressing just one of the two
descent buttons the cutting wire should not move down.
ADJUSTMENTS AND CHECKS
Only qualified people who have been specifically trained and authorised and who are fully aware of the
potential hazards on the machine must be allowed to make adjustments and carry out checks.
The following precautions must be taken before any intervention:
•
Disconnect the machine from the mains.
At the end of each intervention:
• Put all the fixed and/or interlocked guards back in place at the end of the interventions.
CHECKS FOR ALIGNING THE CUTTING WIRE
To check cutting wire alignment proceed as follows:
• CHECKING THE CABLE ASCENT SIDE (7); Drum windings (7): there must be 2,5 windings (not over each
other) (1) (2).
• CHECKING HORIZONTAL ALIGNMENT (3); The line of the wire must be parallel to the work top at about
300 mm (unless required otherwise).
• CHECKING SLIDING OF THE COUNTERWEIGHT in its guard (4).
• CHECKING ALIGNMENT AND perpendicularity of the CABLE JOCKEY PULLEYS (5).
• CHECKING PARALLELISM OF THE CABLE WINDING ROLLER WITH SLIT ON BASE AND PULLEYS
