Operation

Danger
Risk of injury on account of the escaping
water jet that could be hot!
– Only use the interior cleaner in closed
containers.
– Only insert the interior cleaner into a
container or switch it into another con-
tainer while the separate high pressure
pump and internal drive are turned off.
 Place interior cleaner onto container
and lock it.
 Connect the high pressure pump to the
interior cleaner via a high pressure
hose.
 Interior cleaners with electric drives:
Plug in the mains plug.
 Interior cleaners with compressed air
drives: Open the compressed air sup-
ply.
 Open the cleaning liquid supply.
 Switch on the separate high pressure
pump.
Note
With almost all cleaning tasks, 2 nozzles
will achieve a good cleaning result. With
very large and extremely dirty containers, 1
nozzle is used; the other one is locked with
a screw.
Advantage:
– Better cleaning result by larger spray
width and impact force of the cleaning
jet.
Disadvantage:
– The bearings and seals are stressed
more and will wear faster.
– Extension of the cleaning time.

Shutting down

Note
Flush/rinse the interior cleaner for 30 sec-
onds prior to shutting it off. This will avoid
crusting and adhesion and thus a prema-
ture wear of the seals.
 Switch off the separate high pressure
pump.
 Shut off the cleaning liquid supply.
 Interior cleaners with electric drives:
Pull out the mains plug.
 Interior cleaners with compressed air
drives: Shut off the compressed air sup-
ply.
 Remove the interior cleaner from the
container.
