USER MANUAL IB 740 Classic Kärcher

Warning Do not use the appliance when there are other persons around unless they are also wearing safety equipment. The appliance must not be used if a con- necting line or important parts of the appli- ance, e.g. safety devices, spray hose, spray gun. Danger of crushing on account of the dos- ing equipment. Always remove the ma- chine plug from the socket before removing the protective shield of the dry ice contain- er. For the operation of this system the follow- ing regulations and directives are applica- ble in the Federal Republic of Germany (available from Carl Heymanns Verlag KG, Luxemburger Straße 449, 50939 Cologne): – BGV D 26 Spray jet tasks – Executing instructions for BGV D 26 – BGR 117 Working in closed rooms – BGR 189 Using safety gear – BGR 195 Using of safety gloves – BGR 500 Working with spraying devic-

– BGI 534 Working in closed rooms – BGI 836 Gas warner If the emergency stop button is pressed, the dry ice dosing is stopped and the air flow from the nozzle is interrupted. Release the trigger of the jet pistol. Press emergency-stop button. The dry ice dosing is stopped and the air flow from the nozzle is interrupted. Interrupt the compressed air supply. The machine is used to remove dirt using dry ice pellets that are speeded up using an air jet. The machine should not be operated in ex- plosive environments. Use only dry ice pellets as jet medium. Us- ing any other jet medium can cause dam- age to the machine. The air pressure reaches the jet pistol via a pressure regulation valve. The valve opens when the trigger of the jet pistol is pressed and the air flow comes out from the jet pis- tol. Additionally, dry ice pellets are dosaged into the air stream via the dosing device. With the version "IB 7/40 Advanced" the additional dosing can be switched off at the jet pistol. The dry ice pellets hit the surface to be cleaned and remove the dirt. Addi- tional heat currents are formed between the dirt and the object to be cleaned by the -79 °C cold dry ice pellets; this results in the dirt being loosened. At the same time, dry ice immediately gets coverted into gaseous carbon dioxide on contact and requires 700 times the volume of dry ice. Thus, the dirt penetrated by the dry ice thus gets thrown off. During the spraying operation through the jet, a vibrator located on the dry ice contain- er ensures continuous sliding of the dry ice pellets. 1 Push handle 2 Cover of the dry ice container 3 Holder for jet pistol 4 Storage compartment for accessories 5 Operating field 6 Coupling of the control cable 7 Earthing rope with clamp (only IB 7/ 40 Advanced, option for IB 7/40 Clas- sic) 8 Coupling spray agent hose 9 Guiding roll with fixed position brake 10 Transport handle, bumper at the rear 11 Dry ice outlet for emptying the container 1 Cable clamp 2 Mains cable with mains plug 3 Pressure relief valve, condensate draining of the water separator 4 Compressed air connection 5 Condensate drain-out 6 Fuse F1, below the side panel 1 Statistics key, reset counter 2 Key to empty the dry ice container 3 Display 4 Key "increase jet pressure" 5 Key "decrease jet pressure" 6 Increase the dry ice dosing 7 Decrease the dry ice dosing 8 Power switch 9 Emergency-stop button 10 Key switch Specifications and Guidelines Safety Devices Emergency-stop button Switch-off in case of emergency Proper use Function Control elements Device Operating field 14 EN- 3 1 Indicator lamp - control voltage green: Control voltage OK red: Control voltage too low yellow: Emptying of dry ice container active 2 Indicator lamp emergency STOP red: Emergency stop button activated green: Emergency stop button not acti- vated 3 Indicator lamp - compressed air green: Pressure OK orange: selected jet pressure not reached red: Pressure too low (below 0.15 MPa/

The scrambler crushes the dry ice pellets and is mounted between the jet pistol and the nozzle. The alignment of the 4 holes plates in the scrambler indicates the degree of commi- nution. Select the degree of comminution: Display Jet equipment Start up Nozzles Stream jets Scrambler (accessory) 15EN- 4 1 Screw connections 2 Magazine 3 Hole plate Remove the screw connection. Remove the magazine with hole plates. Align the hole plates, as shown above, in the magazine (3 possibilities). The above specifications in the illustration refer to the size of the permeation open- ings. Insert the magazine with hole plates into the scrambler. Unscrew the screw connection and tighten it. An extension piece can be inserted be- tween the jet pistol and the nozzle. The handle can be fastened on the exten- sion piece. 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". 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 be dry and oil- free, at least one aftercooler and a separa- tor must be downstream of the compressor. 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 MPa (10 bar) must not be ex- ceeded. 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 electricity source with proper earthing. The socket used must be accessible and at a height between 0.6 m and 1.9 m off the floor. 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 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. 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 disruptions in operations on ac- count of melted dry ice pellets, it would make sense to fully use up the contents of the dry ice container before adding fresh dry ice. If the machine is to remain idle for a longer time, operate the device until the dry ice container is empty or empty the con- tainer via the dry ice emptying function. 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.

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. Ensure adequate ventilation at the place of use; if possible, use an alarm to warn persons. Symptoms of high levels of carbon dioxide in the air that is breathed in: – 3 p. 5
• %: headache, faster breathing. – 7 %: 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. Follow the safety specifications of the man- ufacturer of dry ice. Danger There is a danger because of dangerous to your health materials. If dust that is danger- ous to your health can be generated, the appropriate safety measures will have to be taken prior to beginning work. Danger Risk of explosion! Do not work on light metals and iron-con- taining substances simultaneously. If you alternate between working on light metals and iron-containing parts, the work area and the suction device must be cleaned between work cycles. Ensure adequate ventilation while working in closed rooms in order to keep the carbon dioxide concentration in the atmospheric air in the room below the danger level. Attach the object to be cleaned if neces- sary. Danger Risk of injury on account of electro-static discharge; risk of damage to the electronic components. The object being cleaned can get charged electrically during the cleaning process. Provide suitable earthing for the object being cleaned and ensure that the earthing remains intact during the entire cleaning process. 몇 Warning Risk of damage by foreign objects falling into the dry ice container. Keep cover of the dry ice container closed during operation. Connect the grounding rope (with IB 7/ 40 Advanced only) electrically conduc- tive with the cleaning object or ground the cleaning object in a different way. Wear safety gear, safety gloves, close fitting safety goggles and ear-protec- tion. Switch on the compressed air supply. Release emergency-stop button by turning. Choose a safe place to stand, assume a secure body stance to avoid being thrown off-balance by the recoil pres- sure of the jet pistol. In order to prevent the sudden recoil, a gradual increase of the jet pressure can be set up (see "Operation/Basic Set- ting", menu item "soft start"). Press in the safety knob of the jet pistol. Activate the dry ice jet by pressing the trigger of the jet pistol and carry out the cleaning operation. Note With model IB 7/40 Advanced, the dosing of dry ice pellets can be switched on or off via the key dry ice dosing on/off on the jet pistol.
