Operation - Kärcher IB 15/120 Manual

Nozzle extension (accessory)
An extension piece can be inserted be-
tween the jet pistol and the nozzle.
Angle jet pipe (accessories)
An angle jet pipe is installed between the jet
gun and the nozzle.
1 Angle jet pipe 105°
2 Angle jet pipe 90°
Warning
Risk of injury. When the angle jet pipe is
used, a torsional moment acts on the jet
pistol in addition to the repulsion power.
Hold the jet pistol tightly.
Start your work with low jet pressure and in-
crease the jet pressure as necessary.
Handle (accessory)
The handle can be fastened on the exten-
sion piece.
Working light (accessory)
(only with Advanced jet pistol)
The working light is connected between the
jet pistol and the nozzle. Switching on and
switching off is described in the chapter
"Operation/Basic Settings".

Connect compressed air supply
Note
For failure-free operation the compressed
air must have a low moisture content. The
compressed air must also be free from oil,
dirt and foreign particles.
The compressor must at least be equipped
with aftercooler, oil and water separator.
 Close pressure relief valve.
 Connect the compressed air inlet pipe
to the compressed air connection point
of the device.
The maximum permissible supply pres-
sure of 1.6 MPa (16 bar) must not be
exceeded.
Establish mains contact
Danger
Risk of electric shock.
The socket to be used must have been in-
stalled by an electrician and be compliant
with IEC 60364-1.
The machine must have an FI fuse of type
B, 30 mA.
Check the mains cables of the machine
each time before using the machine to see
that it is not damaged. Never operate a ma-
chine with damaged cables. Get the dam-
aged cables replaced by an electrician.
The extension cord must be protected by
IPX4 safety mechanism and the cables
must at least be compliant with H 07 RN-F
3G1.5.
 Insert the mains plug into the socket.

Operation

Filling dry ice
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.
 Open the cover of the dry ice container.
 Check the dry ice container for pres-
ence of foreign particles and conden-
sate, remove them if found.
 Fill dry ice pellets into the container.
Caution
Risk of damage to the device. Use only dry
ice pellets as jet medium. The use of any
other spray agent will lead to loss of war-
ranty coverage.
 Close the cover of the dry ice container.
Note
To avoid disturbances due to agglutinated
dry ice pellets, it is useful to fully use up the
contents of the dry ice container before
adding fresh dry ice. If the machine is to re-
main idle for a longer time, operate the de-
vice until the dry ice container is empty or
empty the container via the dry ice empty-
ing function.

Settings
Note
The settings depend on the substances
contained in the detergent and the type of
dirt.
 Release emergency-stop button by
turning.
 Set the appliance switch to "I".
 Turn the keyswitch in a clockwise direc-
tion.
 Increase/reduce the jet pressure by us-
ing the respective keys.
Note
The higher you set the jet pressure, so
much greater (more agressive) will the
cleaning effect be.
 Increase/reduce the dry ice dosing by
using the respective keys.
 Turn the keyswitch counter-clockwise
and remove the key.
The automatic closure of the key hole
will prevent contamination during oper-
ation.
When the key is removed, the device is
protected against changes to the set-
tings and resetting the statistics values.
Operation
 Carry out maintenance jobs "daily be-
fore starting work" (see section "Mainte-
nance and Care").
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).
Do not touch/hold the nozzle opening or the
dry ice jet when the machine is running.
First stop the compressed air supply before
disconnecting the jet gun from the spray
agent hose and the spray agent hose from
the device; remove all pressure from the
system and then pull the plug out of the
socket.
 Cordon off the working area to prevent
persons coming close to the machine
when it is being operated.
Danger
Risk of suffocation on account of carbon di-
oxide. The dry ice pellets are made of solid-
ified carbon dioxide. The carbon dioxide
content in the air at the place where the ma-
chine is used will increase when the ma-
chine is running. Sufficiently ventilate the
workstation and use a personal warning
device or breathing apparatuses, if neces-
sary.
Indication of high carbon dioxide concen-
tration in the breathing air:
3...5%: headache, faster breathing.
–
7...10%: headache, nausea and per-
–
haps even unconsciousness.
If any of these symptoms occur, please
switch off the machine immediately and get
a breath of fresh air; improve the ventilation
before starting work again with the machine
or use respirators.
