DANGER
Danger of accident
The device can start unintentionally. Cold unit parts or
liquid carbon dioxide can cause frostbite. Gaseous car-
bon dioxide can cause death by asphyxiation.
Before working on the device, carry out all the steps in
the "Ending operation" chapter. Wait until the device has
warmed up or wear cold protection clothing. Never put
dry ice in your mouth.
ATTENTION
Risk of damage
Using the wrong detergent can damage the device and
the jet gun.
Never clean the device or the jet gun with solvents, pet-
rol or detergents containing oil.
Service contract
We recommend that you close a service contract to en-
sure reliable operation of the system. Please contact
your KÄRCHER customer service department responsi-
ble.

Performing a reset
Resetting the IB 10/8 L2p
1. Press the reset button inside the device with a
screwdriver.

switched off.
Maintenance plan
Daily before the start of operations
1. Carefully examine the abrasive hose for cracks, kink
points and other damage. Soft spots in the hose in-
dicate wear on the inside of the hose. Replace the
defective or worn hose with a new hose.
2. Examine electrical cables and plugs for damage.
Have defective parts replaced by Customer Service.
Every 100 operating hours
1. Check the couplings on the abrasive hose and on
the device for damage and wear. Replace a defec-
tive hose, have defective couplings on the unit re-
placed by Customer Service.
Every 500 operating hours or annually
1. Have the device checked by Customer Service.
1. Renew the abrasive hose at least every 2 years.
According to DGUV R 100-500, the following tests must
be carried out on the unit by an expert. The results of the
test must be recorded in a test certificate. The operator
of the device must keep the test certificate until the next
test.
After a business interruption of more than a year
1. Check the device for correct condition and function.
After changing the installation site
1. Check the device for proper condition, function and
installation.
After repair work or changes that can affect
operational safety
1. Check the device for proper condition, function and
installation.
Rectification
 Do not pull the trigger of the jet gun before switching it on.
 Remove the fastener on the trigger of the jet gun.
 Check that the control cable of the jet gun is connected to the device.
 Check the control cable on the abrasive hose for damage.
 Increase the air pressure.
 Check the exhaust hose for clogging.
 The carbon dioxide bottle is too hot and therefore has too high a pressure. Set up the device including the carbon dioxide bottle
in a cooler location or protect it from direct sunlight.
 Close the CO bottle.
2
 Allow the device to thaw out (approx. 3 - 4 hours).
 Perform a reset.
 If the malfunction occurs repeatedly, replace the CO
 If the fault persists, contact Customer Service.
 Close the CO bottle.
2
 Allow the device to thaw out (approx. 30 minutes).
 Switch the appliance off and on again.
 If the malfunction occurs repeatedly, replace the CO
 If the fault persists, contact Customer Service.
 Switch the device off and back on again.
 If the fault indicator remains lit, contact the customer service.
 Allow the metering motor to cool down. Position the device so that air can flow into the device from below. Contact Customer
Service if necessary.
 Plug the mains plug into the socket.
 Check the on-site voltage supply.
 Connect a compressed air hose to the device.
 Open the stop valve in the on-site compressed air supply.
 Check the indicator lights and fault indicators.
 Perform a reset.
 Turn the program switch to a higher level.
 Increase the jet pressure.
 Check the filling level of the carbon dioxide bottle.
 Do not use a heated carbon dioxide bottle. Protect the carbon dioxide bottle from heat radiation. The effectiveness of the pellet
production drops sharply if the temperature of the carbon dioxide is above 31 °C.
 Allow the abrasive hose and the jet gun to thaw to clear any blockages. Then increase the jet pressure.
 Turn the program switch to a higher level.
 Replace the carbon dioxide filter between the carbon dioxide bottle and the device.
 Turn the programme switch to a lower level or increase the jet pressure.
 If the jet nozzle is clogged:
a Immediately close the carbon dioxide bottle.
b Allow the unit to thaw for 30 minutes.
c Increase the jet pressure.
d Start the appliance with the carbon dioxide bottle closed to remove pellet residues.
Note
To force a reset, switch the device off and on again.

Troubleshooting
Malfunctions often have simple causes that you can
remedy yourself using the following overview. When in
doubt, or in the case of malfunctions not mentioned
here, please contact your authorised Kärcher Customer
Service.
ATTENTION
Malfunctions
Malfunctions due to contamination.
After each loosening or unscrewing of the screw plug,
the carbon dioxide filter and the copper seal must be re-
placed. If this is not done, particles can become de-
tached from the carbon dioxide filter and lead to
malfunctions.
