OPERATION

The protective guard must always be moun-
ted properly and correctly. Removing the
protective guard causes any moving machi-
ne parts to stop.
To put the machine back into operation, the
protective guard has to be reinserted and
the main switch set to 0.
Wear envisaged personal protection devices
before starting work.
In an emergency, interrupt the operating
of the machine by pressing the red ON/OFF
switch. This causes all moving parts to stop.
Next, disconnect the plug.
The electric motor is protected against over-
load by a thermal cutout. The mixer has to
be switched back on again via the ON/OFF
switch once it has cooled down.
Open the air flow regulator (fig. 12, 15) and the material tap (fig.
12, 16) at the spray lance.
Adjust the flow of material with the delivery volume controller
(fig. 11, 3) on the control unit and set the air quantity by ad-
justing the air flow regulator (fig. 12, 15) to attain the desired
spray pattern.
Important: Never interrupt the water supply
during the processing of dry materials. If no
water is flowing, the machine will stop. Before
putting the machine back into operation, find
out what the cause of the problem is: Tap off,
supply hose bent, tank empty, filter blocked.
The mixture coming out of the spray lance can
be optimised by correcting the water volume.
Change the water flow in 20-l steps with the
water volume regulator (fig. 11, 13) until you
have the right consistency.
Increased material tap wear. Do not use the
material tap to set the material volume. The
delivery volume controller should be used for
this purpose.
In the event of a power failure during the work,
the machine and the hoses have to be rinsed
as soon as possible. Similarly, dismount the
pump, take the rotor out of the stator and wash
it. Next, assemble all the parts.
6.1

REPLACE PUMP CASING

Attention! Before disassembly, make sure
that no residual pressure remains. Watch
the manometer ––> 0 bar.
Switch off machine and disconnect from
power supply.
Remove splint at outlet unit.
Disconnect outlet unit and pump casing.
Mount the desired pump casing (accessory).

PAUSES DURING WORK

Take note the material hardening time.
If at standstill for too long, the material hoses can become
blocked:
In this case, no material can emerge from the spray lance and
the manometer indicates a higher pressure than the normal
operating pressure.
Turn the main switch to 0 to stop the machine.
Look for the blocked part of the hose and hit it with a hammer
to remove the material from the hose.
Attention! If the spray lance is removed or
the lead connections have to be opened,
make sure that there is no pressure inside.
Put the machine into reverse (max. 5 se-
conds) briefly to relieve the pressure.
The material manometer must read 0 bar
and the hoses should be soft, with the ex-
ception of the possible blockage.
The operator carrying out the procedure
must receive an appropriate briefing.
If you are in any doubt whatsoever that the-
re is an remaining pressure in the hoses, the
connections may not be opened.
