Problem
Possible cause
Remedy
The tool support carriage moves vertically
during machining operations.
1. The lock cylinder is leaking air.
2. The vertical clamping aluminium plate
has been inadvertently lubricated.
1. Call for technical assis-
tance.
2. Clean the aluminium plate
from any residual lubri-
cant.
The horizontal movement arms move hori-
zontally during machining operations.
The lock cylinders are leaking air.
Call for technical assistance.
ROTATING BEAD PRESSING DEVICE
No movement is generated when the con-
trol lever is operated.
1. Supply missed.
2. The supply pipes have not been correctly
assembled.
3. The control valve is not working.
1. Check supply.
2. Check pipes fitting.
3. Call for technical assis-
tance.
When the control lever is operated move-
ment arises in one direction only.
The control valve is not working.
Call for technical assistance.
LATERAL LIFTING DEVICE
No movement is produced when the control
pedal is operated.
1. Supply missing or insufficient.
2. The supply pipes have not been cor-
rectly assembled.
3. The control valve is not working.
1. Check supply.
2. Check pipes fitting.
3. Call for technical assis-

When the machine is aired, the lifting
device tends to move, with no consent by
the operator.
When the lifting device is secured to the
machine, the spool that connects the pedal
to the valve has lost its settings.
Re-calibrate the control valve rod slack-
ening the nut between the rod and the fork
and turn the rod in cw or ccw direction
until restoring the correct functioning.
