Read the original instructions before using the device for the first time and act in accordance with it. Keep the original instructions for future reference or for future owners.

• The device is used to remove dirt with dry ice pellets that are accelerated by an air jet.

• The dry ice pellets are produced in the device. This requires liquid carbon dioxide from a dip tube bottle.

• The device may not be operated in a potentially explosive atmosphere.

• The minimum air exchange specified in the "Technical data" section must be observed at the operating location.

• The casing of the device may only be removed by KÄRCHER Customer Service for maintenance purposes.

To ensure trouble-free operation, the carbon dioxide used must at least comply with the following specifications:

• Carbon dioxide technical, class 2.5 or better

• Purity ≥ 99.5%

• Water content (H₂O) ≤ 250 ppm

• NVOC (oil and fat) ≤ 2 ppm

Carbon dioxide snow is created via decompression of liquid carbon dioxide. The gaseous carbon dioxide that also arises is carried away from the workplace via the exhaust hose.

The carbon dioxide snow is pressed into dry ice pellets in the device.

Compressed air reaches the jet gun via a solenoid valve. The air pressure is controlled by an on-site pressure reducer. When the trigger of the jet gun is activated, the valve opens and the air jet emerges from the jet gun. Dry ice pellets are additionally dosed into the air jet via a dosing device.

The dry ice pellets hit the surface to be cleaned and remove the dirt. The -79 °C cold dry ice pellets also create thermal stresses between the dirt and the object to be cleaned, which also contribute to the loosening of the dirt. In addition, the dry ice immediately turns into gaseous carbon dioxide when it hits the surface, thus taking up 700 times its volume. Dirt penetrated by the dry ice is blown away as a result.

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Danger from flying dry ice pellets.

Do not point the jet gun at people. Remove third parties from the operating location and keep them away (e.g. via barriers) during operation. Do not touch the nozzle or the dry ice jet during operation.

Risk of suffocation from carbon dioxide.

During operation, the carbon dioxide content of the air at the workplace increases.

Make sure there is sufficient air exchange at the workplace.

Lay the exhaust hose outdoors, for example, so that nobody is endangered by carbon dioxide.

Note: Carbon dioxide is heavier than air. Make sure that carbon dioxide does sink to lower-lying areas, for example by flowing from the outside into a basement below the workshop (flows).

For longer jet work (longer than 10 minutes per day) and especially in small rooms (less than 300 m³), we recommend wearing a carbon dioxide warning device.

Signs of high levels of carbon dioxide:

3...5%: Headache, high breathing rate.

7...10%: Headache, nausea, possibly unconsciousness.

If these symptoms occur, switch off the device immediately and get some fresh air. Before continuing work, improve ventilation or use a breathing apparatus.

Carbon dioxide is heavier than air and collects in confined spaces, lower-lying spaces or in closed containers. Ensure adequate ventilation at the workplace.

Observe the safety data sheet from the carbon dioxide supplier.

  Note

  CO₂ bottles with a dip tube (also called a riser) are usually marked with a large "T" on the bottle or the back of the bottle.

  In some cases, the dip tube is additionally symbolised by a vertical colour line on the bottle.

• The CO₂ quality must correspond to the specifications in the chapter "Intended use".

• ATTENTION

  Malfunctions

  A residual pressure valve or check valve connected to the CO₂ bottle prevents extraction of the required CO₂ amount.

  If a CO2 bottle with residual pressure valve is used, the ABS residual pressure valve (order number 2.574-006.0), available as an accessory, must be installed between the bottle and the unit.

  ---

  

  1. CO₂ bottle without residual pressure valve
  2. CO₂ bottle with residual pressure valve

As the temperature rises, the effectiveness of pellet production decreases and a larger proportion of carbon dioxide is released in gaseous form via the exhaust hose. Store carbon dioxide bottles as cool as possible (below 31 °C) and protect them from heat, solar radiation and heat during operation.

1. Push the device onto a level, stable surface.

2. Apply the parking brakes on both steering rollers.

3. DANGER

   Risk of asphyxiation

   Danger from substances harmful to health.

   Risk of explosion

   Risk of suffocation from carbon dioxide. The dry ice pellets consist of solid carbon dioxide. The carbon dioxide content of the air at the workplace increases when the device is operated.

   Substances removed from the object to be cleaned are whirled up as dust.

   A mixture of iron oxide and light metal dust can ignite under unfavourable conditions and generate intense heat.

   Lay the exhaust hose outdoors, for example, so that nobody is endangered by carbon dioxide.

   Note: Carbon dioxide is heavier than air. Make sure that carbon dioxide does sink to lower-lying areas, for example by flowing from the outside into a basement below the workshop (flows).

   For longer jet work (longer than 10 minutes per day) and especially in small rooms (less than 300 m³), we recommend wearing a carbon dioxide warning device.

   Signs of high carbon dioxide concentration in the air you breathe:

   3...5%: Headache, high breathing rate.

   7...10%: Headache, nausea, possibly unconsciousness.

   Turn off the device immediately and seek fresh air at the first signs of these symptoms. Before continuing work, be sure to improve the ventilation measures or use a breathing apparatus.

   Observe the safety data sheet provided by the carbon dioxide supplier.

   Adhere to the appropriate safety measures if harmful dusts can arise during the cleaning process.

   Never work on light metals and ferrous parts at the same time.

   Clean the work area and the extraction device before you work on the respective other material.

   When working in confined spaces, ensure that there is sufficient air exchange to keep the carbon dioxide concentration in the room air below the dangerous level.
