Note
The choice of the nozzle depends on the
substances contained in the detergent and
the type of dirt. Recommendations are giv-
en in the application tips at the end of the
operating instructions manual.
All nozzles can be screwed on top of the
threading of the jet pistol without using any
tools. The threaded surfaces on the nozzle
are to be used to loosen tight nozzles using
a spanner.
Caution
Risk of cold welding Smear the enclosed
grease on the nozzle threading before in-
stalling it.
Apart from the round jet nozzle delivered
with the machine, other round jet nozzles
with varying cross-sections are available as
accessories.
 Place the round jet nozzle on the
threaded support of the jet pistol and
tighten it by hand.
1 Diffuser
2 Union joint
3 Nozzle insert
The flat jet nozzle consists of a nozzle in-
sert and a diffuser. Nozzle inserts with var-
ying cross-sections are available as
accessories.

Place the nozzle insert on the threaded
support of the jet pistol and tighten it by
hand.
 Place the diffuser on the nozzle attach-
ment.
 Turn the diffuser in such a way that the
flat jet is properly aligned with the jet
pistol.
 Tighten the union joint by hand.
An extension piece can be inserted be-
tween the jet pistol and the nozzle.
The scrambler crushes the dry ice pellets
and is mounted between the jet pistol and
the nozzle.
The handle can be fastened on the exten-
sion piece or the scrambler.
Note
To ensure smooth functioning of the ma-
chine, the compressed air must have a low
moisture content (max. 5% relative humidi-
ty, dewing point below 0°C). The com-
pressed air must also be free from oil, dirt
and foreign particles.
The compressed air must at least comply
with the air quality conditions of ISO 8573,
Class 3. If the available compressed air is
inadequate or of poorer quality, then the
machine may only be operated with a water
separator attachment (Order no. 2.641-
249.0).
1 Union joint
2 Claw coupling of water separator
3 Pipe clip
4 Compressed air connection for water
separator
5 Screw
 Place the claw coupling of the water
separator on the compressed air con-
nection of the machine and fix it firmly
by turning the claws.
 Tighten the coupling at the union joint.
 Fasten the pipe clip on the machine
frame using the enclosed screw.
 Connect the compressed air pipe to the
compressed air connection of the ma-
chine or the compressed air inlet of the
water separator.
ƽ 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 appliance may only be connected to a

The socket used must be in the viewing
area of the operator.
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
machine with damaged cables. Get the
damaged cables replaced by an electri-
cian.
The extension cord must be protected by
IPX4 safety mechanism and the cables
must at least be compliant with H 07 RN-F
