HLG 2300-LCD:
Switching On / Off (cool air – hot air)
The On/Off switch
3
has 2 settings:
Cool air position
Hot air position
In the cool air position, the unit is suitable for cooling
down a heated workpiece, the hot air gun itself, or
for drying paint.
LC Display
The adjusted settings for the blower stage, measured
temperature at nozzle outlet, program number and
memory function, are indicated on the LC display
8
.
Setting the Temperature
The buttons
7
are used for temperature adjust-
ment in the hot air position. Adjustment is carried out
in increments of 10 °C.
The temperature cannot be adjusted in the cool air
position.
The last set value is retained after switching the unit
off.
Setting the Air Volume/Blower Stage
Button
9
is used for adjustment of the air vol-
ume in the hot and cool air stage.
The last set value is retained after switching the unit
off.
➊
Program Function
Four programs for the most common applications
are factory-preset. These can be changed and mem-
orised as required. The programs can be called up
by pressing button “P”
10
several times.
To return to the standard function “0”, press the but-
ton until no program number is indicated any more.
Pressing the button once more will reactivate the
program function again.
➋
Memory Function
Button “S”
6
is used to memorise changed settings:
– Call up any program
– Set the temperature and blower stage; the xy
symbol flashes
– Press button
6
for approx. 5 seconds until the
symbol
goes out. The set values are now re-
tained.
Instructions for use
Mounting the Nozzle/Reflector
Depending on the application, different nozzles/re-
flectors (accessories) are available.
Slide the nozzle/reflector firmly onto the air out-
let
1
.
Instructions for use
The temperatures specified in the illustrated exam-
ples of use are recommended values which can vary
depending on the properties of the workpiece.
❏
The ideal temperature should first be ascertained
by performing a test. You should therefore start
with a low temperature setting.
❏
The distance between the nozzle and workpiece
is dependent on the material to be processed.
Removing paint / dissolving adhesives
Fit the flat nozzle. Soften the paint using hot air and
remove evenly using the spatula. Do not heat the
paint for too long since this will burn the paint, mak-
ing it more difficult to remove. To carry out work in
confined spaces, remove the heat protection
2
.
Many adhesives (e. g. stickers) become softer when
heated, allowing adhesive bonds to be separated
and superfluous adhesive to be removed.
Shaping plastic tubing
Fit the reflector nozzle. To avoid kinking the tubing,
fill the tubing with sand and seal at both ends. Heat
the tubing evenly by moving it from side to side.
Shrink fitting
Fit the reducing nozzle. Select a heat-shrinkable
sleeve (see Accessories) with a diameter matching
that of the workpiece, e.g. cable lug.
Heat the heat-shrinkable sleeve evenly.
