Failure to follow the warnings and instructions may result in electric shock, fi re and/or serious injury. Save all warnings and instructions for future reference. The term power tool in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. 1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. 2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
English d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. 3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your fi nger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. 4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. 14
English c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power toolʼs operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 5) Service a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. CAUTION Keep children and infirm persons away. When not in use, tools should be stored out of reach of children and infirm persons.

English PRIOR TO OPERATION 1. Power source Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate. 2. Power switch Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident. 3. Extension cord When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. BASIC FUNCTIONS 1. Switch Operations and Temperature Adjustments (Fig. 1, Fig. 2) Slide the knob upward to activate the switch and enable continual operations even when your fi nger is removed. Slide the knob downward as far as it will go to set the switch at the [0] position and turn it off. The position to which the switch is slid will alternate between modes. Switch [1] position: Fixes the wind temperature at 50 C and enables the wind power to be adjusted. Switch [2] position: Enables the wind temperature to be adjusted between 50 C and 650 C, and enables the wind power to be adjusted. 2. Adjusting the Temperature (Fig. 1, Fig. 2, Fig. 3) The temperature can be adjusted between 50 C and 650 C when the switch is at the [2] position. The temperature will rise by 10 C each time the Increase Temperature button is pressed (to a maximum of 650 C.) Press the button continuously to increase the temperature in increments of 10 C. The temperature will decrease by 10 C each time the Decrease Temperature button is pressed (to a minimum of 50 C.) The set temperature will be indicated on the display when the Increase Temperature and 18 Increase wind power button Hot wind release nozzle Increase Temperature button Fig. 1 Display Switch Switch Switch Switch [0] [1] [2] Fig. 2 Display Decrease Temperature button Decrease wind power button Fig. 3
English Decrease Temperature buttons are pressed, but this will return to the hot wind temperature display after a few seconds. The temperature will be fi xed at 50 C when the switch is at the [1] position, and adjustment is not possible. This is used to quickly cool material that is heat-warping and to cool the nozzle when it reaches high temperatures after using the tool. 3. Wind Power Adjustment (Fig. 1, Fig. 3) The wind power can be adjusted in fi ve stages between 1 and 5. (0.25m 3 to 0.5m 3 ) Press the [+] button to increase wind power, and the [ ] button to decrease wind power. The tool can be used with it stood pointing upward. (Fig. 4) CAUTION Fig. 4 Make sure the tool is placed on a stable surface so that it won t topple over when used pointing upward. 4. Attaching the Nozzle (Fig. 5) CAUTION The nozzle is extremely hot immediately after use, so do not touch it. NOTE Fig. 5 Make sure you do not drop the nozzle. Replace the nozzle for a type that is suited to the job in hand. Insert the nozzle supplied fi rmly into the hot wind release nozzle until it can go no further. 5. Temperature Settings WARNING Hot wind release nozzle Nozzle (Plane) Do not use the tool in the vicinity of volatile substances (thinner, gasoline, etc.) Do not bring the hot wind release nozzle in close contact with your hands or face during use. The nozzle is extremely hot immediately after use, so do not touch it. Set the temperature in consideration of the article to be heated. Also, pay attention to the surrounding material that will be heated at the same time. First of all, apply the hot wind from a distance while checking that there are no changes in the article being heated, and then move it closer until it reaches an appropriate distance. Heating inflammable substances (paper, wood, plastic, etc.) Set the switch to the [1] position and apply the heat with the nozzle at least 10cm away from the article being heated. Gently move the tip of the nozzle up, down, left and right to apply the heat. Applying heat constantly to one location may result in malformation or the outbreak of smoke. 19
English Heating non-flammable substances (metal, stone, concrete, etc.) Set the switch to the [1] position, and if there are no problems, move it to the [2] position. Apply the heat with the nozzle at least 5cm away from the article being heated. Holding the nozzle too close may result in the tool overheating, leading to malfunctions. WORK EXAMPLE CAUTION Parts of the nozzles supplied are sharp, so use gloves when removing them from the case and when attaching or detaching them. Select the nozzle in consideration of the shape of the article being heated and the area being heated. 1. Peeling off paint (Fig. 6) Use nozzle (fl at) or nozzle (round) to soften the paint with the hot wind, and then remove it with the scraper supplied. Note that heating the paint too much may result in it scorching and becoming harder, making it difficult to scrape off. 2. Softening adhesive (Fig. 7) Use nozzle (fl at) or nozzle (round) to soften the surface and make it easy to peel, and then pull up one of the edges, blow heat underneath it and gently peel it off so that none of the adhesive remains. 3. Heat wrapping (Fig. 8) Use nozzle (fl at) to heat-wrap shrink fi lm and tubes. The material will change color or crack if hot air is blown onto it from a close distance, so maintain an appropriate distance while monitoring progress. 4. Forming resin pipes (Fig. 9) Use nozzle (curved surface) to evenly heat the circumference of the resin pipe. To prevent the inside of the pipe from narrowing when bending it, etc., pour sand inside, block both ends and then gently bend it.
