activate the trigger switch on the blasting gun
for a few seconds for activating the battery
indicator / digital control display.
check that the battery is fully charged
(battery indicator).
adjust the blasting pressure
(the working pressure).
activate the trigger switch on the blasting gun
for a few seconds to allow air to
flow
through
the system.

When the cleaning task has been completed, the
following procedure must be carried out before the
machine is dismantled or stored:
• empty the dry ice tank.
• activate the trigger on the blasting gun for a few
seconds in order to empty the system of pos-
sible dry ice residue.
• close the main compressed air supply.
• activate the trigger switch on the blasting gun
again for a few seconds in order to depressurise
the system.
• make sure that the emergency stop is in off
position -when pushed in.
• disconnect the main air supply.
• avoid kinking the blasting hose, especially when
rolling it up.
eMergeNcY sToP
activation of the emergency stop immediately stops
the blasting air stream and dry ice dispensing.
before the machine can be restarted, the following
procedure must be carried out:
• the emergency stop must be put back to the
correct operating position.
• the blasting air stream can now be restarted by
activating the trigger switch on the blasting gun.
fAiLUre/fAULTs
if when using the machine the operator notices that
the outer protection sleeve on the blasting hose
looks or feels
inflated
in any way, the machine must
be stopped immediately.
• close the main air supply immediately.
• activate the trigger switch on the blasting gun
until the system is depressurised.
• activate the emergency stop.
• remove the main air connections from the machine.
• remove the blasting hose and send it for repair
and pressure testing at the manufacturer’s test
facilities.
• the dry ice tank might be empty, but the
system must not be blasted through until a new/
repaired blasting hose has been connected.

“ The operator must not try to
repair the blasting hose. it must be sent
to the manufacturer for repair ”
the outer hose sleeve protects the operator from any
exposure caused by wear and tear of the inner hose.
no pressure is permissible in the outer sleeve during
operation. Therefore, any sign of
inflation
means that
the inner hose is in some way defective. for safety
reasons the machine must then be stopped immedi-
ately and shut down as described above. if a defec-
tive blasting hose is used, the operator risks serious
injury from being hit by dry ice pellets.
The operator must not try to repair the blast-
ing hose. it must be sent to the manufacturer
for repair for two reasons:
a) the manufacturer has special tools for making
perfect repairs.
b) in accordance with regulations, a renewed pres-
sure test must be carried out on the hose and a
new pressure test
certificate
issued.
Never disconnect
the blasting hose when the
machine is connected to main electricity and air sup-
plies, otherwise activation of the blasting gun trigger
switch will result in blasting air being discharged
through an open connection instead of through the
gun nozzle. the operator will then loose control of
the air stream and might be seriously injured.
the main electrical connection supplies the battery
charger with 100 V/230 V + 0 + earth (cee17 plug
with earth). the control circuit uses 24 V.
in the off position, the emergency switch cuts off
voltage to the control circuits, but does not make
the machine voltage-free.
the machine is only voltage-free when the battery
is disconnected. therefore, the control cabinet must
not be opened, and the electrical junction box on
the dosing unit motor must remain closed until the
battery has been removed.
if electrical supply failure occurs the machine will
not start. if the blasting air stream is disconnected
the dry ice dosing unit stops.
air supply failure stops the blasting air stream
during operation. the air stream decreases and dis-
appears completely when the pressure in the system
falls below 0.5 bar. the main valve for blasting air
closes when the control pressure is below this value.
the dosing unit motor will continue to run for as
long as the trigger switch on the blasting gun is
activated. therefore, in order to prevent the dispen-
sing unit from being damaged the trigger must be
released no later than when the main valve shuts off
the blasting air stream.
A mesh guard is
fitted
in the dry ice tank to prevent
operators from coming into contact with moving
parts of the dispensing unit during operation. if the
guard is removed, all machine functions stop. on
refitting
the guard the machine becomes ready to
start without further intervention.
machine stop caused by guard removal is thus not
an emergency stop demanding machine restart. it
is solely a safety device that automatically activates
when the guard is removed. this stop function must
in no way be
modified
or bypassed.
