To start up the machine turn the main switch
(39)
(red on a
yellow background) clockwise to the
I
position.
Turn the selector start/stop/reverse
(40)
on position
1
and
check that the machine is pumping normally and modify
the output according to your necessity through the buttons
that set the output “plus”
(41)
and “less”
(42)
.
Put the selector
(43)
on position
2
and check that the
rotation direction reverses.
Check that the remote control works properly.
Turn the selector start/stop/reverse
(39)
and the remote
control selector
(44)
on position
1
and by operating the
remote control, check that the machine starts and stops
normally.
The lamp
(45)
lights when the inverter interferes to protect
the motor against overload.
If the pilot light
(46)
is switched on, it shows that the
control panel is energized.
The line socket must always be disconnected when
you operate on the machine and above all on the
electric board.
Before starting the machine, pour some water in the
hopper to avoid that the worm gear runs dry .
Check that the protection grill is well mounted and
fixed on the hopper.
Before turning on the machine, be certain that no
one, except the operators, is standing too close to it.
Be careful: the machine must always run with
material or water in the hopper.
If this is not the case, the pump will wear out
quickly.
Working pressure is indicated by
the gauge
(37)
positioned in
the pumping group.
The
“standard
working
pressure” value depends on
the material and hoses used:
it is recommendable to check
out systematically -on the mortar
hoses pressure gauge- the value indicated in order to
promptly find out any fault.
To ease this procedure, a pressure control device is
available
(38)
(optional extra)
which must be coupled
directly to the gun.
