Description – purpose of use

Hot (el. resistance) knife Extol® Premium 8894570 is intended for cutting, making grooves and holes in foam plastics (boards) such as for example foam (expanded) polystyrene, extruded polystyrene (Styrodur), foam (lightened) PVC boards (Palfoam), set sealing (insulation) PU foams, plastic foam, etc. Furthermore, it can be used for cutting polypropylene cellular boards, for cutting plastic hoses and nylon rope. The hot knife is not intended for cutting hard (PVC) pipes and polypropylene (PP) pipes.
The hot knife has an adjustable temperature (5 temperature control levels) and an anti-slip ergonomic handle for comfortable holding during work.

Preparing for use

WARNING

• Prior to putting the device into operation, carefully read the entire user‘s manual before first use and keep it with the product so that the user can become acquainted with it. If you lend or sell the product to somebody, include this user‘s manual with it. Prevent this user‘s manual from being damaged. The manufacturer takes no responsibility for damages or injuries arising from use that is in contradiction to this user‘s manual. Before using this device, first acquaint yourself with all the control elements and parts as well as how to turn it off immediately in the event of a dangerous situation arising.
  Before using, first check that all parts are firmly attached and check that no part of the device, such as for example safety protective elements, is damaged or incorrectly installed, or missing. Damage is, likewise, considered to constitute damaged or degraded insulation on the power cord or a damaged power cord plug. Do not use a device with damaged or missing parts and have it repaired or replaced at an authorised service centre for the Extol® brand – see chapter Servicing and maintenance, or the website address at the introduction to this user‘s manual.

• Prior to turning on the hot knife, first install the depth limit stop and use the screw (fig. 5, position 6) to set the depth of cut, i.e. distance of the limit stop from the edge of the blade (fig. 6). Then secure the limit stop at the set distance by tightening the screw. To adjust the depth of cut, allow the hot knife to cool down sufficiently.

WARNING

• Prior to turning on the hot knife, first prepare the supplied stand and set the hot knife in the stand as shown in fig. 7.

WARNING

• Prior to plugging power cord into an el. power socket, check that the voltage in the socket is in the range from 220 to 240 V~50 Hz. The hot knife can be powered using this voltage.

TURNING HEATING UP ON/OFF

• To start heating up, turn the control knob to level 1-5.
  The lit LED indicator light indicates that the device is turned on, but it does not indicate whether the set temperature has been reached. The temperature is automatically controlled using a thermostat and overheating cannot occur. To turn the device off using the control knob, turn it below level „1“ so that the LED indicator light turns off.

IMPORTANT INFORMATION ABOUT THE TEMPERATURE SETTINGS

• The temperature may differ from the specified tempera- ture level values and may vary across the different parts of the blade because the heat source is a resistive element that may have a different temperature in each part of the device. The specified temperature for the given level is only approximate. The hot knife is able to cut the materials for which it is intended. The intended materials are specified in chapter Characteristics-purpose of use.
• At levels 1 and 2, the temperature may be insufficient for thicker boards and it may not be possible to cut a board at such temperature settings, however, it may be ideal for thin boards and materials. This must be verified using a practical test on a sample piece of material. The highest temperature setting (at level 5) will not damage polystyrene and can be set to make a faster and cleaner cut. The optimal temperature setting is determined by performing a practical test on a sample piece of material.
• Allow the hot knife to heat up, seated in the stand, to the required temperature for a few minutes (approx. 3-4 minutes).

Working with a hot knife

ATTENTION

• When working with a hot knife, ensure that the workplace is sufficiently ventilated because fumes from the melted plastics may be emitted when plastic is melted. Inhalation of these fumes is damaging to health.

CUTTING – LINEAR CUT

• Plunge the hot knife into the material, whilst the depth of cut is defined by the distance of the limit stop from the edge of the blade.
• Guide the hot knife at an appropriate speed, whilst applying appropriate pressure in the direction of the line of cut. Excessive pressure will not speed up the cutting process. To speed up the cut, it is possible to move the blade back and forth.

MAKING HOLES/ROUND CUT-OUTS

• To make holes/round cut-outs, set the depth of cut using the limit stop based on the thickness of the board and on whether the circular cut-out is intended to penetrate through the board entirely or only to a certain depth in the board. Then plunge the  blade into the foam board and turn the blade around the central axis of the blade to burn out a circle having the diameter defined by the height of the blade (fig. 2a) or if a larger hole/cut-out is required, guide the blade along its edge as shown in (fig. 2b). In the event that it is not necessary to cut a round cut-out through the board, but rather just a round cut-out in the board, subsequently use the blade to melt out the area inside the circle to the required depth.

MAKING GROOVES

• Use the limit stop to set the small plunge depth based on the thickness of the board. Plunge the blade into the board and if it is necessary to melt a wider groove, tilt the blade to the side, where the width of the groove is determined by the tilt angle of the blade (fig. 3) and then guide the tilted blade along the line of the cut as necessary.

PUTTING OUT OF OPERATION

• When you have finished working with the hot knife, turn the control knob below level „1“ so that the LED indicator turns off, place the hot knife into the stand and disconnect the power cord from the el. power source, and allow the hot knife to cool down in
  the stand.

CLEANING THE HOT KNIFE

• It is not necessary to clean the hot knife because, when used on the prescribed materials, plastic does not drip on the hot knife.

ATTENTION

• The hot knife may change its colour with use. Over time, it may become darker in colour. This is not a fault, but rather the effect of high temperature. Change in colour does not have any effect on the functionality of the device.

Safety instructions and warnings

• Connect the device into sockets equipped with a residual current device (RCD) with a shut-off current of 30 mA, which must be part of the permanent electrical installation approved by an electrical inspector having the necessary accreditation.
• The hot knife is very hot when turned on, risk of burns. Do not touch the hot parts before they cool down.
• Do not operate the device in locations with a flammable or explosive atmosphere. Do not place the device in the vicinity of easily flammable materials. Prevent the device from coming into contact with flammable liquids, organic solvents and corrosive substances (acids, lye, water, salt solutions, bleaches, etc.).
• Do not operate the device in the rain or in a wet environment. Prevent water from entering the inner parts of the device. Risk of injury by electrical shock in a wet environment.
• Do not leave the device turned on without supervision.
• Norm EN 60335-2-45 requires that the user‘s manual for portable heat tools, the following information is provided. It is left up to the reasonable consideration of parents, whether they allow children 8 years of age and older to use this tool or not. Prevent the device from being used by persons (including children) whose physical, sensory or mental disability or incapacity or insufficient experience or knowledge prevents them from safely using the device without supervision or instruction. Children must not play with the device. It is generally not assumed that the device will be used by very small children (age 0-3 years inclusive) and used by small children without supervision (age between 3 and 8 years). It is conceded that seriously handicapped persons may have needs outside the level specified by this norm (EN 60335-1 and EN 60335-2-45).
