Mini Pump 22
8 Service and maintenance
Make sure that the machine is not turned on accidentally when maintenance work and
repairs are being performed (disconnect the current entry).
The Mini pump has been built in such a way that it requires only minimum maintenance.
However, in order to ensure perfect operation, the mixing tube, beater and material hopper must
be free of hard material remains at all times.
The electronic control panel must be kept dry and free of dust inside. Whenever
necessary, remove dust from the control panel using a vacuum cleaner and after disconnecting
the pump from the mains. We do not recommend blowing compressed air since dust lifted as a
result is deposited on the connection contacts and may render these unusable.
The reducer motors are lubricated for their entire working lives. However, if any grease is
expelled, it must be replaced with ENERGREASE or a similar lubricating substance. If this
happens, make sure not to exceed the specific amounts. Also, make sure that no material is stuck
to the stator refrigeration wings or ventilator.
The York absorption valve of the water hose from the drum to the machine must be
cleaned daily before starting work and the pressure reducer filter must be cleaned once a week;
in order to perform this last operation, use the special valve supplied with the machine.
WARNING! :
When assembling the filtering deposit, make sure that the ring seal is
correctly positioned.
Whenever necessary, use a damp cloth to clean the water metre indicator tube. If the
indicator tube has turned dark in colour due to interior adhesions, remove the tube by loosening
both joint screws and clean it inside using a cloth. Never use a metallic brush or similar device!
In order to ensure that the air diffuser can move freely inside the spraying lance tubing at
all times, grease this slightly after cleaning.
Before performing any maintenance or cleaning work on electrical equipment,
remove the plug from the mains.
From time to time, remove the electrical connectors from the control panel
and apply a little grease to the contacts. This will ensure the proper functioning of the connectors
and prevent the contacts from burning.
Remove and shake the filter disks on the extraction side of the membrane compressor and
on the other side at least twice a week when cleaning the interior and every 14 days when
cleaning the exterior. In this respect, make sure that the filters with thick soft surfaces are placed
outwards and the thin hard surface filters inwards.
