Shutting Down; Transport - Kärcher IB 7/40 Classic Manual

 Switch on the compressed air supply.
 Release emergency-stop button by
turning.
 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.
NOTICE
With model IB 7/40 Advanced, the dosing
of dry ice pellets can be switched on or off
via the key dry ice dosing on/off on the jet
pistol. When the dosing is turned off, the
key illuminates red, the display shows "ice
off".
In addition,
with the IB 7/40 Advanced model, the jet
pressure and the dry ice volume can be
changed on the jet pistol.
Warning
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.
NOTICE
During longer breaks in operations, the dry
ice pellets can melt in the dry ice container.
As far as possible, do not interrupt opera-
tions for more than 20 minutes. In case of
extended interruptions, switch off the en-
gine.
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.
NOTICE
Please dispose of condensate in an envi-
ronmentally friendly manner.

Shutting down

DANGER
Risk of cold burns. Dry ice has a tempera-
ture of -79 °C. Never touch dry ice or cold
parts of the machine without appropriate
protection. Wear protective gloves and pro-
tective overalls.
DANGER
Risk of injury on account of flying dry ice
pellets. Do not direct the jet pistol on per-
sons. Keep third persons away from the
place of use and when the machine is being
operated (by cordoning off the area).
 Close the compressed air supply.
 Place the collection trough under the
condensate drain screw.
 Open the pressure relief valve slowly
and wait until the condensate and the
compressed air have been drained
from the device.
 Place the collection trough under the
dry ice exit.
 Press the key to empty the dry ice and
wait until the dry ice container is empty.
The dry ice emptying stops after the
preset time has elapsed (see "Basic
Settings").
If needed, press the key to empty the
dry ice container several times.
NOTICE
Please dispose of condensate in an envi-
ronmentally friendly manner.
 Set the appliance switch to "0/OFF".
 Disconnect the machine from the com-
pressed air inlet.
 Disconnect the main plug from the
socket.
 Clean and roll up the grounding rope.

Transport

Danger
Risk of accident on account of dry ice resi-
due in the device. Remove all traces of dry
ice before transporting the device in closed
vehicle; otherwise there is a risk of carbon
dioxide suffocation to the co-passengers.
 Carry out all the steps listed in the chap-
ter "Shut down" before transporting the
device.
 Mount the appliance on the transport
vehicle.
