Service and maintenance
In all maintenance and repair works we must make sure that the machine cannot get started
unexpectedly (unplug the network supply).
The MASTER has been designed to need a minimum maintenance. However, to ensure its
perfect operation, the mixing tube, the mixing tree (mixer), the feed auger, the material deposit and the
vent hole shall never have any hardened material left.
The bronze fitting of the feed auger shall never be lubricated or moistened. It shall be replaced
if necessary.
The circuit board must be dry and without dust inside. If needed, the dust on the circuit board
can be hovered once the plug has been switched off. It is not recommended to blow compressed air, as
the dust raised is deposited on the connection contacts and they might remain useless.
The gear boxes are lubricated for their whole operating life. If grease came out of them, it
should be replaced with ENERGREASE or a similar lubricating substance. Then, we shall pay
attention not to exceed the limits indicated.
The thimble filter in the machine water inlet shall be cleaned daily before starting to work and
the filer on the pressure reducer, once a week.
WARNING!
When assembling the filter vase, we must pay attention that the joint is
correctly settled.
So that the air diffuser can always move inside the spraying gun carcass, it must be slightly
lubricated once the cleaning is finished.
Before starting to work in electric devices, unplug the machine from the net.
We should take out from time to time the electric connectors from the circuit
board, and lubricate slightly the contacts. This way we preserve the good operation of
the connectors and we prevent them from burning.
We should take out and shake the filter on the membrane compressor sucking in side and the
opposite one, at least twice a week, when cleaning the inside and every 14 days when cleaning the
outside. Then, we shall place the filters with the rough and soft surface outwards and with the thin and
hard surface inwards.
