The sealing point between nozzle and gutter should be checked in particular before
extended idle periods. A non-tight nozzle seal leads to blocking of the suction extraction
lead during extended idle periods.
Testing
procedure
With the nozzle seal closed, apply a couple of drops of solvent to the sealing point with
the spray bottle. If the seal is not tight, the solvent will be sucked into the suction
extraction lead. In this case damage to the O-ring must be assumed. To replace the O-
ring the cross head screws of the clamping plate must be loosened. Subsequently the
screws must be tightened again and the tightness must be checked again as described
above.
