Special Safety Instructions

For your own protection and for the protection of your power tool, pay attention to all parts of the text that are marked with this symbol!
Never look inside the blow-out pipe!
Never use the hot-air blower for drying your hair!
Always wear goggles and work gloves!
Pay attention when using the hotair fan near flammable materials. The device must not be used if explosive gases are present.
This device can be used by children from 8 years of  age and, in addition, by persons with impaired physical,  sensory or mental ability or lack of experience  or knowledge  if they are supervised or have received induction training on the use of the device and understand the associated risks. Children may not play with the device. Cleaning and user maintenance may not be performed by children unless  supervised.
Risk of burns: Never touch the hot blow-out pipe.
Never use power tools when damp, or in a damp or wet environment.
Take special care when using tools near combustible materials. Never direct at the same point for long periods.
Heat can be directed to concealed combustible materials.
Never direct the hot-air blower at highly flammable materials! Fires can be caused if the hot-air blower is not used with great care.
Never leave the tool unattended when it is running.
After long periods of use at maximum temperature, the temperature should be lowered before the tool is switched off. This lengthens the service life of the heater.
Place the tool on the bases provided following use and wait until it has cooled down before placing in storage!
Store your tools in a safe place.
Unused tools should be stored in a dry, locked room inaccessible to children.
Always take care where there are toxic gases and a risk of explosion.
Toxic can be created when working on plastics, paints and similar materials. Risk of fire and combustion!
Only use the hot-air blower in well-ventilated rooms!
Never inhale the vapours created!
For your own safety, only use accessories and auxiliary devices specified in the Operating
Instructions or recommended or specified by the tool manufacturer.
The use tools or accessories other than those recommended in the Operating Instructions or in the catalogue can result in a risk of injury.

Use

Before commissioning, check that the rated mains voltage and mains frequency stated on the type plate match your power supply.
The distance to the object being processed depends on the material and intended processing type. Always first carry out an inspection of air volume and temperature! The attachable nozzles (see chapter 9.) available as accessories can be used for precise hot air control to a specific point or a surface.
Take care when changing hot nozzles! Danger of burns.

6.1 HG 16-500
The sliding switch (4) can be used to switch the tool on and off for selecting between 2 stages (for air volume and temperature).
Stage 1: 300 °C, 240 l/min
Stage 2: 500 °C, 450 l/min
6.2 HG 20-600
The sliding switch (4) can be used to switch the tool on and for selecting between 3 stages.
The air volume varies in the 3 stages (150/300/500 l/min).
At stage 1 of the sliding switch (4) the temperature is always 80 °C (cold-air stage). Use the cold-air stage to dry paint, cool workpieces or to cool down the nozzle before changing an accessory part.
At stage 2 and 3 of the sliding switch (4), the temperature can be set steplessly at the adjusting wheel (6).
The numbers 1 – 9 shown on the adjusting wheel are used for orientation. “1” means 80 °C.”9” means 600 °C (maximum temperature).
6.3 HGE 23-650 LCD
The sliding switch (4) can be used to switch the tool on and for selecting between 2 stages.
At stage 1 of the sliding switch (4) the temperature is always 80 °C (cold-air stage). Use the cold-air stage to dry paint, cool workpieces or to cool down the nozzle before changing an accessory part.
At stage 2 of the sliding switch (4) the temperature can be set steplessly.
Setting temperature:
Briefly pressing the joystick (10) to the left/right increases or lowers the set value in 10 ° steps. Longer pressing of the joystick (10) changes the value faster.
Note:
If the desired temperature is set, the blower (depending on the selected speed/air volume) needs a few seconds to reach the set value. The “°C” symbol flash during this period.
When the hot-air blower is switched off, the last value set is retained.
Setting air volume:
Pressing the (8) button and then briefly pressing the joystick (10) to the left/right sets the air volume or fan speed.
Program operation:
Four programs for the most frequent types of work are set in the factory. Press the “P” button for program operation. The display shows for program 1. Pressing the program button again, takes you to the programs , and . Press the button again to return to normal operation.
Program 1: Forming plastic pipes
Program 2: Welding plastic pipes
Program 3: Removing paint
Program 4: Soft soldering (technical data see chapter 12.)
Changing programs and saving:
The values in the four programs can be changed and saved. To do this, first press the “P” program button until the program to be changed is displayed. Set the desired air volume and temperature. Press the “P“ program button for saving until the symbol disappears from the display (about 2 seconds). The entered values are now saved in the program.
Note: – To return from program operation to the normal function, press the program button (9) until the program symbol in the display (7) has disappeared.
– The factory settings of the programs are listed in chapter 12.
6.4 HGS 22-630
The sliding switch (4) can be used to switch the tool on and for selecting between 2 stages.
The air volume varies in the 2 stages (stage 1: 150-300 l/min, stage 2: 300-500 l/min).
At stage 1 and 2 of the sliding switch (4), the temperature can be set steplessly at the adjusting wheel (6).
The numbers 1 – 9 shown on the adjusting wheel are used for orientation. “1” means 80 °C.”9” means 630 °C (maximum temperature).
6 .5 Stationary operation
If you wish to use the hot-air blower as a stationary tool, ensure that it is placed on a safe, anti-slip and clean base.
To use the hot air gun in stationary operation, place it on the anti-slip bases (5).

Maintenance

The air inlet (3) must be free from foreign bodies. Clean the air inlet (3) gif necessary.
For the HGS 22-630 remove the fine dust filter (3) for cleaning (see fig., page 2). Replace worn fine dust filters. Replacement filter set: order no. 344199400.

Troubleshooting

Thermal protection in the event of heat the accumulation (only for HGE 23-650 LCD):
A thermal switch switches off the heater in case of excessive interference in the air outlet of the blowout opening (heat accumulation). However, the blower continues running. When the blow-out opening is free again, the heater cuts in again automatically after a short while. The thermal switch can also trip after the tool is switched off. In this case, after the tool is switched on again it takes longer than usual until the temperature at the blowout opening is reached. Thermal fuse in the event of overload (for all devices): The thermal fuse switches the tool off completely in the event of overloading. See chap. repairs!
