Control of the load sensor
It is necessary to control if the load sensor is working properly and that it
allows you to maintain the desired levels.
A low load will cause a decline in the level and the possibility of not having the
amount of necessary hot-melt adhesive. By contrast, an overload can cause
the overfilling of the tank with subsequent sealing of the loading mouth.
The load sensor should remain clean of charred adhesive that may affect the
proper level detection.
Inspection of the aspiration tube
Monitor that the aspiration tube is not obtured with sticked glue pallets or
perls. This tube should be perfectly free of any glue plugs that impedes the
smooth transfer of the adhesive from container to the tank of the melting unit.
The tube is mostly transparent to facilitate visual inspection of the same.
Filter maintenance
Periodically review the state of the filter located inside the discharge zone.
Blow compressed air impurities that may have acceded to.
This filter avoids dust particles or glue pallets itself being spilled outside with
the exhaust air. If it arrived to be plugged the system might not work properly.
To clean, unscrew the three screws of the rotary elbow lid and extract the
filter.
Control of pneumatic vibrator
Reviewing the correct operation of the pneumatic vibrator located in the
suction mouth. Ensures that it vibrates and its vibration is adequate.
Clean up the exhaust silencer of impurities and adhesive dust.
