○ There may be a diﬀ erence between the displayed

temperature and the actual temperature.

○ Press and hold the + and - temperature control buttons

at the same time to switch between Fahrenheit (°F) and

Celsius (°C).

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 air 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 inﬂ ammable substances

(paper, wood, plastic, etc.)

Set the switch to the [set I] position and apply the heat

with the nozzle at least 10 cm 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.

Heating non-ﬂ ammable substances

(metal, stone, concrete, etc.)

Set the switch to the [set I] position, and if there are no

problems, move it to the [set II] position.

Apply the heat with the nozzle at least 5 cm away from

the article being heated.

Holding the nozzle too close may result in the tool

overheating, leading to malfunctions.

CAUTION

The nozzle is extremely hot immediately after use, so do

not touch it.

Insert the nozzle ﬁ rmly into the front cover until it can go no

further.

You can remove the nozzle without touching it by rotating the

front cover counterclockwise.

NOTE

○ Be careful not to remove the nozzle during work.

○ When removing it, be careful not to damage the

surroundings or the nozzle.

When using the tool facing up, place it on a stable

surface.

When working with both hands, such as when bending

a pipe, you can lay down the heat gun and use it with the

nozzle side facing up.

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.

NOTE

Do not block the intake or nozzle during use.

1. Peeling oﬀ paint (Fig. 11)

Use nozzle (plane) or nozzle (round) to soften the paint

with the hot air, and then remove it with the scraper.

Note that heating the paint too much may result in it

scorching and becoming harder, making it diﬃ cult to

scrape oﬀ .

2. Softening adhesive (Fig. 12)

Use nozzle (plane) 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. 13)

Use nozzle (plane) 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. 14)

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.

5. Defrosting water pipes (Fig. 15)

Use nozzle (curved surface) to heat the frozen area from

the edge to the center. Do not mistake gas pipes for water

pipes and heat them.

Take care to avoid damaging frozen resin areas on water

pipes.
