Ending Operation - Kärcher IB 10/8 L2P Originalbetriebsanleitung

2. Cordon off the work area to prevent peo-
ple from entering during operation.
DANGER
Risk of asphyxiation
Risk of suffocation from carbon dioxide.
The dry ice pellets consist of solid carbon
dioxide. The carbon dioxide content of the
air at the workplace increases when the de-
vice is operated.
Lay the exhaust hose outdoors, for exam-
ple, so that nobody is endangered by car-
bon dioxide.
Note: Carbon dioxide is heavier than air.
Make sure that carbon dioxide does sink to
lower-lying areas, for example by flowing
from the outside into a basement below the
workshop (flows).
For longer jet work (longer than 10 minutes
per day) and especially in small rooms (less
than 300 m³), we recommend wearing a
carbon dioxide warning device.
Signs of high carbon dioxide concentration
in the air you breathe:
3...5%: Headache, high breathing rate.
7...10%: Headache, nausea, possibly un-
consciousness.
Turn off the device immediately and seek
fresh air at the first signs of these symp-
toms. Before continuing work, be sure to
improve the ventilation measures or use a
breathing apparatus.
Observe the safety data sheet provided by
the carbon dioxide supplier.
Danger from substances harmful to
health.
Substances removed from the object to be
cleaned are whirled up as dust.
Adhere to the appropriate safety measures
if harmful dusts can arise during the clean-
ing process.
Risk of explosion
A mixture of iron oxide and light metal dust
can ignite under unfavourable conditions
and generate intense heat.
Never work on light metals and ferrous
parts at the same time.
Clean the work area and the extraction de-
vice before you work on the respective oth-
er material.
3. When working in confined spaces, en-
sure that there is sufficient air exchange
to keep the carbon dioxide concentra-
tion in the room air below the dangerous
level.
4. Fasten light cleaning objects in position.
DANGER
Danger of electrostatic discharge
The cleaning object can become electro-
statically charged during the cleaning pro-
cess. The subsequent discharge can cause
injuries and damage electronic assemblies.
Ground the object to be cleaned and main-
tain it during the cleaning process.
5. Electrically ground the object to be
cleaned.
6. Wear protective clothing, protective
gloves, tightly fitting safety goggles and
hearing protection.
7. Activate the compressed air supply.
8. Open the stop valve on the carbon diox-
ide bottle.
9. Turn the program switch to level 3.

10.Choose a safe place to stand and adopt
a safe posture so as not to be unbal-
anced by the recoil force of the jet gun.
Cleaning with dry ice pellets
1. Select operation with pellet jet using the
compressed air / pellets button. (The in-
dicator light must not light up.)

Lights up red: Compressed air jet
Off: Pellet jet
2. Set the jet pressure on the on-site pres-
sure reducer to the desired value. Maxi-
mum pressure: 10 bar. Minimum
pressure:
● Level 1: 0.7 bar
● Level 2: 1.4 bar
● Level 3: 2.8 bar
Note
The pressure is shown in the display. If the
minimum pressure is not reached or the
maximum pressure is exceeded, the dis-
play flashes.
3. Point the jet gun away from your body.
4. Push the safety lever of the jet gun up-
wards and at the same time activate the
trigger.

The working light switches on at the
same time as the pellet production.
5. Wait until the pellet jet has built up.
ATTENTION
Never operate the device without or with
an empty carbon dioxide bottle.
Use the program switch to select a higher
level or change the carbon dioxide bottle if
no pellets come out of the jet gun after 5
minutes of jet.
6. If necessary, turn the program switch
back to level 2 or 1.
ATTENTION
Risk of damage
Coarse pellets may possibly escape.
Check the cleaning performance on a non-
visible area first to avoid damage.
Note
If there are interruptions in the dry ice
stream, increase the blasting pressure or
set a lower level on the programme selector
switch.
7. Direct the pellet jet at the object to be
cleaned and remove the dirt with the jet.
8. Release the trigger.
The pellet jet stops.
English
The working light goes out after 30 sec-
onds.
9. Insert the jet gun with the retaining cone
into the holder on the device.

10.Close the stop valve on the carbon diox-
ide bottle if the work break lasts longer
than 30 minutes.
Compressed air without pellet jet
Loose dirt can be removed with com-
pressed air without dry ice pellets.
1. Select operation with compressed air
using the compressed air/pellets button.
(The indicator light must light up red.)

3. Direct the compressed air jet at the ob-
ject to be cleaned and remove the soil-
ing.
4. Release the trigger.
The compressed air jet stops.
The working light goes out after 30 sec-
onds.
5. Insert the jet gun with the retaining cone
into the holder on the device.
6. Close the stop valve on the carbon diox-
ide bottle if the work break lasts longer
than 30 minutes.

Ending operation

1. Release the trigger of the jet gun.
2. Close the stop valve on the carbon diox-
ide bottle.
3. Pull the trigger on the jet gun until no
more pellets come out.
4. Turn the program switch to level 1.
5. Shut off the compressed air supply.
6. Operate the trigger on the jet gun until
