Problem - The Board Does Not Slide - Virutex EB140 Manual De Instrucciones

6 - The operating pressure must be 6 bar. The machine may
operate poorly if the pressure is lower than this. The machine
is equipped with a safety device that prevents it from being
started if the pressure is below ~ 4.5 bar.
Check the compressor efficiency and make sure that the pres-
sure switch A (Fig. 78) is set to 6 bar. (See section 5.1.2).
7 - The machine operates only when the glue has reached the
set temperature (min. 175ºC). Observe the temperature on
screen B (Fig. 78). If after ~ 20-25 minutes the glue still fails
to reach the operating temperature, contact your distribu-
tor or nearest authorised technical service centre to test the
electrical components, such as the machine resistors, control,
probe, etc.
Also see section 6.1 "Errors," on page 34.
8.3 PROBLEM – THE BOARD DOES NOT SLIDE
Likely causes
1 - The feeder height is not set according to the thickness of
the board.
2 - The feeder is not parallel to the work table, lengthwise in
the direction of movement.
B
Solutions
1 - Adjust the height of the feeder according to the board
thickness, checking the measurement on the counter A (Fig.
79). It is very important for the handle B (Fig. 79) to be loose
during the setting operation.
2 - This anomaly appears when the feeder is set while the
handle B (Fig. 79) is locked; the setting must be redone with
the handle B loose.
CAUTION
Adjusting the feeder without unlocking the handle B (Fig.
79) may cause a permanent misalignment in the shafts,
and make the board feed more difficult indefinitely. If
this is the problem, contact your distributor or authorised
technical service.
