MASTER plastering machine

-
Clean, dry and place the mixing tree again after having taken out the cleaning tool. When
the mixing tree is wet, the dry material gets stuck to it when it starts and cause breakdowns.
-
Take out from the spraying gun the rubber nozzle and clean it with water.
-
Connect the cleaning adapter to the product hose and introduce a rubber ball. This ball is
impelled by the water force through the hose, cleaning it. The rubber ball remains on the
spraying gun diffuser.
-
After having closed the cleaning connection, disconnect the spraying gun from the hose and
this from the cleaning connection.
WARNING!
So that nothing comes into the hose, join both couplings on both ends of the
hose when they still unwound. This way we avoid breakdowns caused by external reasons.
-
Once the air diffuser has been taken out of the spraying gun, we can move the rubber ball
away. The air diffuse will be cleaned using the pick handle and water. The spraying gun is
cleaned with water. Special attention is to be paid to the cleaning of the nozzle, and that it
doesn't get pressed by the material pressure coming from the spraying gun.
-
In longer work interruptions, and at least when finished working, the water has to be
released from the dose, especially by frost hazard (cold areas). We only need to open the
evacuation keys. Besides, we must blow air inside the water taps, to which aim we connect
the compressor to the machine water inlet, the water hose is disconnected from the mixing
tube, and with the evacuation keys open, the air is blown using the push button of the
electric valve. The compressor is connected to the main switch.
WARNING!
If water is released in summer or winter, we will find no surprises because of
frost!
-
When working with gypsum rendering, it is necessary to clean at least once a day the pump
opening. If not so made, a material deposit is created on the pump outlet because of a
higher pressure and, as a consequence, a bigger wear of the pump parts. Loosening both
fastening screws, the mixing tube stator support is easily taken into pieces to be able to
clean it thoroughly.
-
Cleaning the dry material hopper is only necessary if we are working with a different dry
material or when the machine is stopped during a long time.
4.3
Stopping the machine
If the MASTER, for instance in winter, must be stopped for a long time, it is recommended to
unscrew the stator from the rotor, apart from the cleaning steps described before. This way we avoid
the stator outline to get deformed and the rotor to get stuck.
