  • I = 50°C, air flow 350 litres/minute

  • II = 450°C, air flow 350 litres/minute

  • III = 600°C, air flow 500 litres/minute

  • 8040

  • I = 50°C + air flow 250-500 litres/minute

  • II = 50°C … 650°C, air flow 250-500 litres/minute

  • when using it for the first time, some smoke may emit from the tool; this is normal and will soon cease

  • switch off the tool by pushing switch A in position “0”

• Temperature setting

  • there is a tolerance on the indicated temperatures
    50…90°C: max 90°C
    less than 300°C: ±20%
    more than 300°C: ±10%
    8020

  • use dial wheel M to select the desired temperature setting

  • use table 6 for reference 8040 7

  • set desired target temperature in steps of 10°C by pressing buttons B briefly

  • pressing buttons B constantly increases/decreases the target temperature continuously until the buttons are released or the minimum/maximum temperature is reached

  • after the target temperature is set, display D shows flashing arrows until the desired temperature is reached (in position “II” only)

  • the target temperature will be stored in the memory of the tool, so that each time after switching on the tool heats up to the last selected target temperature

• Air flow setting 8 (8040)

  • set desired air flow in steps of 50 l/min by pressing buttons C briefly
  • display D shows the actual air flow setting in a bar graph

• Memory setting 9 (8040)

  • to select one of the four stored memory settings press button P
  • to store a temperature and air flow setting press button P to select a memory location, set the desired temperature and airflow, and press and hold button N to store the setting

• General use

  • determine the right temperature by testing out on an inconspicuous part of the workpiece; start with a low temperature setting
  • the temperature drops as the distance between the air outlet/nozzle and the workpiece increases
  • the temperature required depends on the material to be worked on

• Stationary use 10

  • set the tool down on its rear in an upright position
  • make sure the surface is clean and dustfree; polluted air damages the motor
  • make sure the air flow is directed away from you
  • secure the cord to prevent pulling down the tool
  • do not touch the air outlet/nozzle
  • make sure nothing drops into the air outlet/nozzle
  • carefully hold the tool with one hand while switching it off with the other hand, and then allow it to cool down

• Holding and guiding the tool 11

  • hold the tool with one hand
  • keep ventilation slots F 2 uncovered

• Standard accessories 2

  • glass protection nozzle G (for deflecting air flow)

  • round nozzle H (for concentrating air flow)

  • reflector nozzle J (for reflecting airflow)

  • reduction nozzle K (for concentrating air flow)
    NOTES:

  • all application examples (except removing paint next to glass) can be performed without accessories; however, using the appropriate accessory simplifies the work and significantly improves the quality of the results

  • this tool can also be used in combination with commonly available accessories for heat guns

• Mounting/removing accessories

  • simply fit the accessory onto air outlet L 2
  • remove an accessory by pulling it off to the front after it has cooled down
  • mount an accessory only when the air outlet is cold, when the switch is in position “0” and when the plug is disconnected
  • use nozzle release ring E for easy removing hot nozzles 12

• Constant heat control (overload protection)
  Protects heating element from damage when tool is overloaded without having to stop it and/or let it cool down for a period of time

  • when the temperature gets too high, the heating element switches itself off, while the motor continues to run and produces cold air
  • when the temperature has dropped sufficiently (taking only a few seconds), the heating element will be switched on automatically
  • when the tool is switched off after working at a high temperature setting, and switched on again after a short break, it may take a while before the heating element reaches the desired temperature

APPLICATION ADVICE

• Removing paint/lacquer 13
  • use a clean, sharp scraper
  • scrape firmly, when the paint softens
  • experiment to establish the length of time necessary to apply the heat for optimal results
  • scrape the softened paint immediately, or it will harden again
  • keep a 30° to 40° angle between the tool and the workpiece
  • remove paint and debris immediately from the scraper to prevent them from ignition
  • scrape with the grain of the wood, wherever possible
  • do not direct the hot air flow towards the same surface for too long
  • dispose of all paint debris safely
  • thoroughly clean the work area after completing the job
  • be careful when removing layers of paint in old buildings; in the past the building may have been painted with paint containing lead, which is highly poisonous
  • exposure to even low levels of lead can cause serious brain and nervous system damage; young and unborn children are particularly vulnerable
  • have lead-based paint removed by a professional without using a heat gun

OTHER APPLICATION EXAMPLE:
removing (synthetic) wall covering

• Removing paint/lacquer next to glass 14
  • always use glass protection nozzle G when working next to glass
  • remove the paint with a hand scraper
  • do not use the tool for removing paint on metalframed windows; metal is heat-conducting which might lead to breaking of the glass
• Removing stickers (use round nozzle H) 15
  • many adhesives become softer when heated, allowing adhesive bonds to be separated and superfluous adhesive to be removed
  • heat sticker on the upper side
  • always take care not to overheat the underlying surface

OTHER APPLICATION EXAMPLES:

• removing linoleum and vinyl carpeting
• removing carpet tiles made of synthetic fibres
• removing veneers/applying veneer strips
• softening/melting tar, tin, bitumen, wax (use round nozzle H)
• waxing (skis, furniture) (use glass protection nozzle G) 16
• removing resin
• loosening rusty/too tightly fastened metal screws, nuts and bolts
• removing candle wax (do not overheat the underlying surface)
• repairing broken candles/restoring bent candles to their original shape
• Shrink fitting 17
  • use reflector nozzle J or reduction nozzle K
  • select a shrink-fit tube with a diameter matching that of the workpiece
  • heat the shrink-fit tube evenly

OTHER APPLICATION EXAMPLE:

shrink-wrapping

• Soldering water pipes 18
  This tool is most suitable for working with soft solders (melting point below 400°)

  • use reflector nozzle J
  • thoroughly clean both joining sections before soldering
  • pre-heat both sections and apply soldering wire (do not use lead-based soldering wire)
