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.

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.

The basis for a safe operational plant is reg-

ular maintenance.

Use only original parts of the manufacturer 

or part suggessted by him, such as

– replacement and wear parts

– Accessory parts

– Fuel

– Detergent
