6 COMMON ERRORS AND SOLUTIONS
Fault Solutions
Machine won’t
start
Check if any alarm appears on the DISPLAY (for more details, read the annex "Touch screen
operating manual"). Also, confirm all the exterior conditions (electricity, compressed air).
Chipping on
board
The occurrence of chips may be due to the use of inadequate panel, which may even have nails
inserted (for example, chipboard).
Check the condition of cutters to verify that there are no broken blades. Proceed according to
annex "Pre-milling Station Operating Manual" to carry out this operation.
Irregular edge
feeding
First, check that air pressure at machine entrance is correct (between 6 and 7 Bar).
Feed a panel and check that the pressure piston pressure is approximately 0.15MPa. To do this
watch the MR5 manometer keeping in mind that it is always at zero and it only shows pressure at
the exact moment it is feeding, that is, for 1.5 second approximately. Too much air pressure also
can cause irregular feeding.
Check the condition of the gearbox drive that moves the feeding roller.
Check that the edge roll is not caught at any stage, which prevents its natural movement (it could
be the case of small strips of adhesive tape stuck at the bottom of the roll and hardly visible at first
sight).
Board moves
at end trim
First, carefully read the annex “End Trim Operating Manual” and check that all pneumatic pressures
are correct.
Disconnect air pressure supply from the machine and manually check that the group performs all its
movements smoothly.
Clean the carriage guide bars and tracers with a cloth dampened in machine oil, wiping them dry
afterwards so that dirt does not catch on again. Wheels and chain must be clean so that they do not
lose adherence.
Less
radius/milling
at trimmers
First, carefully read the annex “Top and Bottom Trim Operating Manual” and check that all
pneumatic pressures are correct.
Check unit tracing: when feeding a panel the unit must trace 1mm frontally and vertically.
Board un-
alignment
If it is evident that the board does not advance, maintaining parallelism and tracing throughout the
process, check the correct pressure beam height along the condition of the chain pads and wheels.
If necessary, clean with a mild, neutral solvent.
In small pieces, it is possible to tighten the pressure beam 0.5 mm more than the panel
measurement. Tightening more than 1mm would mean forcing the drag chain motor to work. This
causes overheating and excessive wear of the wheels and tires of the pressure beam.
Check the tracing of the pressure rollers, for more details, read the appendix "Operation manual of
the roller base".
Verify that the pressure of the guillotine according to the appendix "Operating Manual of the
Feeding Tray". In some cases, the pressure is increased in order to process high edge thicknesses
and is not restored when the edge is changed again, causing vibrations.
Irregular
gluing
First, carefully read the annex “Gluepot user manual ”.
Check gluepot quantity and status.
Verify gluepot tracing and pressure, and notice that the board is not moved by any of the working
groups, and the gluepot maintains uniform tracing along the path of a long board.
Observe the condition of the gluing roller. Contact a trained technician to perform the maintenance,
if necessary.
Check that the board cutting is 90 degrees.
