Interrupting Operation; Basic Settings - Kärcher IB 15/120 Betriebsanleitung

Carbon dioxide accumulates in lower situ-
ated places. Prevent accumulation by
means of active ventilation measures.
Follow the safety specifications of the man-
ufacturer of dry ice.
Danger
There is a danger because of dangerous to
your health materials. If dust that is danger-
ous to your health can be generated, the
appropriate safety measures will have to be
taken prior to beginning work.
Danger
Risk of explosion!
Do not work on light metals and iron-con-
taining substances simultaneously.
If you alternate between working on light
metals and iron-containing parts, the work
area and the suction device must be
cleaned between work cycles.
Danger due to dust explosion. If inflamma-
ble dusts are formed during work, accumu-
lations of dust must be avoided. Regularly
remove dust before critical amounts are ac-
cumulated.
 Ensure adequate ventilation while
working in closed rooms in order to
keep the carbon dioxide concentration
in the atmospheric air in the room below
the danger level.
 Attach the object to be cleaned if neces-
sary.
Danger
Risk of injury on account of electro-static
discharge; risk of damage to the electronic
components. The object being cleaned can
get charged electrically during the cleaning
process. Provide suitable earthing for the
object being cleaned and ensure that the
earthing remains intact during the entire
cleaning process.
Warning
Risk of injury on account of tripping and fall-
ing.
Lay spray agent hose and control line in a
way that they do not pose a risk of stum-
bling during work.
Caution
Risk of damage by foreign objects falling
into the dry ice container. Keep cover of the
dry ice container closed during operation.
 Connect the electrically conductive
earth wire to the object to be cleaned or
earth the object to be cleaned in anoth-
er way.
 Wear safety gear, safety gloves, close
fitting safety goggles and ear-protec-
tion.
 Switch on the compressed air supply.
 Release emergency-stop button by
turning.
 Set the operating type for the com-
pressed air jet to "1" or dry ice jet to "2"
on the operating type switch of the jet
pistol.
 Choose a safe place to stand, assume
a secure body stance to avoid being
thrown off-balance by the recoil pres-
sure of the jet pistol.
In order to prevent the sudden recoil, a
gradual increase of the jet pressure can
be set up (see "Operation/Basic Set-
ting", menu item "soft start").
 Press in the safety knob of the jet pistol.
 Activate the dry ice jet by pressing the
trigger of the jet pistol and carry out the
cleaning operation.
Note
When using the Advanced jet pistol, the
dosing of dry ice pellets can be switched on
or off via the dry ice dosing on/off key on
the jet pistol. When the dosing is turned off,
the key illuminates red, the display shows
"ice off".
Moreover, when the Advanced jet pistol is
used, the jet pressure and the dry ice quan-
tity can be adjusted on the jet pistol.
Caution
Risk of damage to the dosing equipment on
account of dirt. Keep the lid of the dry ice
container closed during the spraying oper-
ation to prevent sprayed off dirt from enter-
ing it.
Switch-off in case of emergency
 Release the trigger of the jet pistol.
 Press emergency-stop button.
The dry ice dosing is topped and the air
flow from the nozzle is interrupted.
 Interrupt the compressed air supply.
Switching on after emergency-stop
 Release emergency-stop button by
turning.

Interrupting operation

 Release the trigger of the jet pistol.
 During breaks in operation, you can in-
sert the jet pistol on the holder on the
machine.
Note
During longer service interruptions, the dry
ice pellets can agglutinate in the dry ice
container. As far as possible, do not inter-
rupt operations for more than 20 minutes.
In case of extended interruptions, empty
the dry ice container.
Drain off the condensate.
A water separator cleans the compressed
air flowing to the device. This collects con-
densate in the water separator, that needs
to be drained once in a while.
 Place the collection trough under the
condensate drain screw.
 Open the pressure relief valve slowly
and wait until the condensate has been
drained from the device.
Note
Please dispose of condensate in an envi-
ronmentally friendly manner.
