FAULT CAUSE REMEDY
The machine
does not start.
TROUBLE SHOOTING 1/2
“ Dry Ice Pellets evaporate immediately
on striking the object. ”
The machine is
turned on but it
does not blast.
No supply of electricity.
The emergency stop is activated
(pressed inwards).
The blasting gun has not been
activated.
No supply of compressed air.
No electrical connection between
the gun and the blasting hose
AND/OR between the blasting
hose and the machine.
Loose connections, defective plugs,
damaged cables.
The ow of air and dry ice is blocked
because the blasting hose is kinked
or extremely inexed.
“Motor Failure”
“Motor Overload”
“Valve Overload”
Check that the battery is fully charged
and correctly connected.
For more information: See page 13.
Release the emergency button
(pull outwards and make
sure it can turn).
Activate the blasting gun.
Check the machine is properly
connected to a source of compres-
sed air and that the air actually
ows into the machine.
The air hose must be inated and
rigid, and that the pressure must
be veried in the manometer on
the front panel.
Make sure the electrical plug of the
gun is correctly attached to the
electrical socket of the blasting
hose, and make sure the plug at
the other end of the blasting hose
is correctly plugged into the socket
on the front of the machine.
Check all connectors, cables, replace
defective parts or correct loose
connections.
Straighten up the blasting hose.
The motor needs replacement
– call for a service engineer.
Press the emergency stop button.
Pull it out again after 5 seconds.
Call for a service engineer.

FAULT CAUSE REMEDY
The machine
blasts but there
is no projection
of dry ice.
Continuous loss or
leakage of air.
TROUBLE SHOOTING 2/2
The machine’s tank is empty.
The passage of dry ice to the
dozing system is blocked, probably
because of clumps or “cakes” of
dry ice pellets.
The tank is not vibrating so the
dry ice does not ow to the dozing
system. The pneumatic vibrator is
either frozen or defective.
The dozing system is blocked
because the dozing disc is not
rotating.
Rust or other impurities blocking
the main valve or the pilot pressure
regulator.
The hose is defective or broken.
Rell the tank with dry ice pellets.
Empty the tank, remove the clumps
or cakes, blast inside the tank with
plain air in order to remove remain-
ing obstacles and humidity that might
eventually turn into ice and produce
more blockages.
Empty the pellet tank and let the
vibrator unfreeze (or warm it up with
hot air). Make sure that the internal
air pressure supplied to the vibrator is
at least 4.5 bar/ 65 psi, and that the
throttle valve is sufciently open. For
more information se page 10.10
The vibrator needs replacement if it is
defective or malfunctions in any way
- or if none of the above measures
should manage to solve the problem.
If the problem were caused by a
mechanical blockage of the disc
due to a foreign object that might
have fallen into the tank , then the
system will have to be dismantled
and the disc would have to be
examined and replaced if damaged.
Open the mentioned units, clean
or remove impurities, lubricate the
piston inside the pilot pressure
regulator, examine rubber
membranes and replace if damaged.
The hose must be replaced
IMMEDIATELY.
“ With the proper IceTech nozzle
accessories you can perform powerful and
sensitive cleaning with an exceptionally
low air consumption. ”
The blasting hose gets
inated or bulks.
