irst time of use

A small quantity of smoke may occur when the tool is used

or the first time. This smoke is caused by binding agents

released from the heater's insulating film during the first time

of use. To let the smoke escape quickly, the tool should be

set down on its standing surface. The area you are working

in should be well ventilated when using the tool for the first

ime. Any smoke coming out of the tool is not harmful!

esidual heat indicator (HG 2320 E only)

The residual heat indicator serves as a visual warning to

prevent injury from direct contact with the hot nozzle outlet.

he residual heat indicator also works when the tool is

unplugged.

The indicator starts working after the tool has been in use

for 90 seconds and keeps flashing until the temperature

at the nozzle outlet has fallen below 60 °C at room tempera-

ture. The residual heat indicator does not show if the tool

has been in operation for less than 90 seconds. Responsi-

bility always rests with the user and care must be taken at

all times when handling hot air tools.

These hot air tools are doubly protected from

overheating:

1. A thermostat switches the heater off if too much of the air

outlet nozzle is obstructed (heat build-up). However, the

blower continues to run. A warning triangle on the display

tells you that the heater is switched off.

Once the air delivery nozzle is clear again, the heater

automatically switches back on again after a few

moments. The warning triangle then goes out. The

thermostat may also respond after switching the hot air

tool off, taking it longer than usual to reach temperature

at the air delivery nozzle when it is switched on again. *

2. The thermal cut-out completely shuts down the tool

if it is overloaded. **

For your safety Tool description - Operation

Please note: The distance from the object you are working

n depends on material and intended method of working.

Always try out the airflow and temperature on a test piece

first. Using the attachable accessory nozzles (see acces-

ories page on the cover) the flow of hot air can be con-

trolled with maximum precision.

ake care when changing hot nozzles! When using

the hot air tool in the self-resting position, make sure it is

tanding on a stable, non-slip and clean surface.

HG 2120 E

The tool is switched on and off at the two-stage switch (7)

on the back of the grip handle. In addition to three-stage

speed/airflow control (stage 1 is a cooling stage at 80 °C ),

temperature can be continuously adjusted over a range of

80 °C – 630 °C in settings 2 and 3 at the thumbwheel (8).

The numbers 1 - 9 on the thumbwheel serve as a guide

only. Whereas "1" means 80 °C, the maximum temperature

of 630 °C is attained at "9". Airflow can be adjusted to the

three stages of 150 / 150-300 / 300 -500 l/min. The guard

sleeve (3) detaches at a bayonet catch.

Switching ON causes brief voltage drops. If the mains

power supply system is not absolutely stable, other

equipment may be affected. No disturbance is likely to

occur with mains impedances of less than 0.43 ohms.

HG 2320 E

1. Operation (HG 2320 only)

The tool is switched on and off at a two-stage switch (7)

on the back of the grip handle. The joystick (9) is used for

controlling temperature and airflow or fan speed.

2. Setting temperature (HG 2320 only)

Stage 1 is the cooling stage, temperature is always 80 °C.

Use the cooling function for drying paint, cooling workpieces

or for cooling the nozzle before changing the accessory at-

tachment. In stage 2 temperature can be infinitely varied

over a range of 80 °C - 650 °C on the control panel with

LCD display. The actual temperature is measured at the

nozzle outlet and indicated on the display. The joystick (9)

is used as an input button with plus/minus function. The

temperature setting range begins at 80 °C and ends at a

maximum of 650 °C.

Briefly pressing the "+/–" joystick increases or reduces the

temperature setting in 10° steps. Keeping the joystick

pressed speeds up the temperature setting process. Once

the temperature has been set, the tool takes a few seconds

to reach temperature (depending on speed/airflow). The

temperature setting selected is shown on the display for

3 seconds. The display then shows the current actual

temperature. The "°C/°F" symbol continues to flash until

the selected temperature is reached.

If you want to alter the setting, simply press the joystick

again to increase or reduce the temperature. After switching

off, the hot air tool stays in the last setting.

3. Setting airflow rate (HG 2320 only)

o change the airflow rate, first press the "airflow" button;

the fan symbol flashes. Now use the joystick to set the air-

low rate. The airflow rate setting mode automatically closes

if the airflow rate setting is not changed within 5 sec. Press-

ing the airflow button again after setting the airflow rate

mmediately closes the airflow rate setting mode. The airflow

rate can be varied from a minimum of 150 l/min to a maxi-

um of 500 l/min.

4. Programming mode [P] (HG 2320 only)

esides normal operating mode, the HG 2320 E also has

our factory-set programs for the most frequent jobs. Four

rograms are factory-set for the most common types of

work. Press button "P" for programming mode (11).

Number 1 is displayed for program 1. Continuing to press

the program button will take you to programs 2-4. Pressing

the button again will return the tool to normal operation. See

page 3.

Preset programmes

5. Memory function [S] (HG 2320 only)

The values selected for the four programmes can be

changed and memorised at any time. To do this, first press

the program button "P" (11) until the display shows the

program you wish to change. Set the temperature and

airflow rate you require. Memory symbol on the LCD

flashes to indicate that the user programme selected has

been changed. To memorise this setting in the user pro-

gramme selected, press and hold down the programme

selector button. The memory symbol continues to flash for

approx. 2 sec. The settings entered are saved once the

memory symbol stays on all the time. To return to normal

operation, press the program button until the program

symbol disappears from the display. To return to normal op-

eration, press the program button until the program symbol

disappears from the display. See page 3.

6. Changing the power cord (HG 2320 E only)

If the power cord is damaged, it can easily be changed

without opening the casing.

1. Important! Disconnect tool from power supply.

2. Undo screw and pull off cover cap

3. Release cable grip

4. Undo mains terminals

5. Pull out cable .

6. Insert new cable and secure in reverse order

(1. Firmly screw down mains terminals etc.).
