any other liquid. Connect the product to the power network providing the voltages and frequencies indicated on the nameplate of the unit, exclusively. The plug of the power cord must match the power socket. Do not modify the plug. Do not use any power adapters to adapt the plug to the socket. An unmodifi ed plug, which matches the socket, reduces the risk of an electric shock. A product with fi rst class electrical insulation must always be connected to an outlet equipped with a protective conductor. The mains power supply should be equipped with a residual current fuse with a tripping current of 30 mA or less. After each application, unplug the power cord from the power socket. Always disconnect the device from the power supply, if it is left unattended, and before putting it away, disassembling, or cleaning. Do not leave the device unattended when it is connected to the power supply. Do not overload the power cord. Do not use the power cord to carry the prod- uct, connect, or disconnect the plug from the power socket. Avoid any contact between the power cord and heat sources, oil, sharp edges, and moving parts. Damage to the power cord increases the risk of an electric shock. If the power cord is damaged (e.g. it is cut, its insulation is melted), immediately unplug it from the wall socket, and return it to an authorised service facility. It is not allowed to use the product with a damaged power cord. It is not allowed to have the power cord repaired. It must be changed for a new one at an authorized service centre. Disconnect the power cord from the power socket, before installing, removing, or adjusting any of the product accessories. Make sure that the selected accessory has been installed correctly, before start- ing the product. Do not overload the product. The temperature of the housing must not exceed

C. Overloading the product will accelerate its wear and tear, lead to its dam- aging, and increase the risk of an electric shock. The product must be kept under supervision at all times during operation. The product is not to be used by children. Keep the product and its power cord out of the reach of children. It is important to ensure that children do not see the product as a toy. Children should not be allowed to clean or maintain the product without the su- pervision of an adult. Keep the device out of reach of children if it is powered or is cooling down. This product cannot be used by people with impaired physical and/or mental abil- ities, and by people without any experience in or understanding of the operation of the product, unless they are supervised or instructed in the safe use of the product, so that they understand the relevant operating risks. PRODUCT OPERATION Preparing the tool for operation Caution! The procedure described in this section must be carried out when the tool is unplugged from power supply. Make sure that the power cord has been unplugged from the mains socket. Ensure that the shaft of the tool cools down completely. Lift the wire part of the stand so that it rests on the protrusions of the hinge. This will allow the tool to be placed in a wire recess. Place the tool so that the recess is between the handle housing and the adapter, while the shaft is directed upwards (II). The weight of the tool should prevent the stand from closing. Select one of the adapter for your job. The wire stretched on the frame is used for cutting where the lowest thickness possible matters most, e.g. when cutting small parts. The size of the part is limited by the shape formed between the frame and wire.12 ORIGINAL INSTRUCTIONS

The hot rod adapter is used for free cutting of polystyrene foams and the thick- ness of cut is greater than in the case of wire cutting, while there are no size limits. The engraving adapter is used to cut low-thickness foamed polystyrene or to cut diff erent shapes in foamed polystyrene. Connect the selected adapter to the handle by inserting it in the handle socket (III). Switching the device on and off Note! As soon as the unit is switched on, it will start to heat up and then maintain the rated temperature automatically when it is reached. Therefore, make sure that the switch is in the OFF setting, and then connect the selected adapter to the tool. Connect the power supply plug (IV) to the socket at the end of the handle. Switch the tool ON and then keep the tool on the stand so that the cutting blade does not come into contact with any object and is not close to any fl ammable materials. Keep away at least 10 cm from the cutting blade. Place the tool stand on a non-fl ammable surface. Caution! The cutting blade is very hot. It can cause severe burns when in contact with the skin. Avoid contact with random objects, as high temperatures can dam- age them and cause fi re. Caution! It is forbidden to use any power supply other than the one included in the set. In case of loss of or damage to the power supply, contact the manufacturer for a new one. Tool operation The tool can be used only to cut foamed polystyrene which is clean, without any residues of glue, paint, varnish or other dirt. Dirt can prevent cutting or catch fi re when in contact with the hot knife. Start cutting after the heating up phase is completed. The heating time depends on the adapter used, while the wire heats up faster than the rod blades. Cut with a smooth motion and adjust the cutting speed to suit a thickness of the material. Do not pause the cutting when the blade is in the material. It is recommended to carry out cutting tests on waste material. When cutting through the material, make sure that the hot knife does not damage the surface. Put the polystyrene material on the edge of your worktable to make the cut on the part of the material protruding beyond that edge. After fi nishing the work and when the tool is not in use, place it on the stand. Cooling and replacing the cutting blade If you need to replace the cutting blade during operation, put the tool on the stand, switch it OFF, and then allow some time until the cutting unit has cooled down completely. Do not accelerate the cooling by immersing the cutting blade in water or other liquid for instance.

MAINTENANCE AND STORAGE

After use, put the tool on the stand, disconnect it from the power supply by un- plugging the power supply plug and allow it to cool down completely. Clean the housing of the unit with a slightly damp cloth, then dry or leave to dry. Never immerse the tool housing in water or other liquids. Do not use alcohol, solvents, corrosive or abrasive agents for cleaning. Clean the cutting blade with a copper or brass brush. If you notice damage to the shaft, contact the manufacturer to obtain spare parts. Using the tool with a damaged cutting blade (e.g. bent, burnt) is not allowed. Store the product in dry, shaded and well aired places. Ensure that the storage room protects the device from unauthorised access, especially by children. It is recommended to store the product in the packaging it was delivered in.13 ORIGINAL INSTRUCTIONS

Replacing the heating wire If the cutting wire is deformed permanently, broken or there is too much dirt on it, replace it with a new one. Replace the cutting blade only after it has cooled down completely and the tool switched off and unplugged. Use pliers to remove the whole worn wire. Be careful not to damage the wire frame. The ends of the frame come with grooves. Wind several coils of wire on the fi rst groove. Then drag the free, longer end of the wire to the groove at the other end of the frame and wound a few coils around it. Wrap the free ends of the wire around the wire for approx. 1 cm (V) and cut off the rest with pliers.14 ORIGINALANLEITUNG
