MAINTENANCE
Depressurizing the system
Warning: System pressurized at a high temperature. Before any procedure,
disconnect the hoses and applicators, completely depressurizing the system.
Failure to follow these precautions may lead to serious personal injury.
1. Disconnect the equipment switch located on the front.
2. Operate the purge valve housed in each distributor to free any residual
pressure from the circuit.
3. Manually purge (or use the corresponding control command) all the
applicators that have been used.
Platen maintenance
It is necessary to discharge the circuit using a cleaning product whenever the
equipment will remain unused for several days or when changing the type of
adhesive.
Contact the adhesive manufacturer to choose the best cleaning product and to
obtain instruction on its use. Request and read carefully the technical specifi-
cations for the product.
When restarting production, remove cleaning product remains with the new
adhesive.
The platen has a PTFE coating to improve its non-stick property. This means
that platen cleaning is relatively easy. Cold material may be removed by
pulling on it gently. If necessary, the platen may be heated to 60-80ºC to make
adhesive removal easier.
Warning: Do not use sharp tools or scrapers with sharp edges.
Regarding to the platen seals is recommended cover it with grease after the
drum change or after work to preserve it and prevent cracks.
Pump maintenance
Inspecting for leaks
The pump is equipped with a gasket system on the shaft to prevent adhesive
from leaking through it. On occasion, some adhesive may leak out, which
makes it necessary to retighten the screws or change the gasket.
Warning : Changing the gasket with a hot pump.
Release the shaft coupling from the pump. Retighten or remove the screws
that hold the gasket in place. Replace the gaskets and reassemble the parts.
