General Safety Instructions

WARNING – Reading the operating instructions will reduce the risk of injury.

Failure to follow all safety warnings and instructions may result in electric shock, fire and/or serious injury.
Keep all safety instructions and information for future reference. Before using the power tool, carefully read through and familiarise yourself with all the enclosed safety information and the Operating Instructions.
Keep all enclosed documentation for future reference, and pass on your power tool only together with this documentation.

Special Safety Instructions

Never look inside the outlet tube!
Never use the hot air gun for drying your hair!
Always wear goggles and work-gloves!
Pay attention when using the hot-air 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 outlet tube.
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 gun at highly flammable materials! Fires can be caused if the hot air gun 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 gun 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 plugging in, check that the rated mains voltage and mains frequency, as stated on the rating label, match with 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.

H 16-500
The sliding switch (4) can be used to switch the tool on and off and for selecting between 2 stages (for air volume and temperature).
Stage 1: 300 °C, 240 l/min
Stage 2: 500 °C, 450 l/min

metabo H 16-500 Hot Air Gun 2

HE 20-600
The sliding switch (4) can be used to switch the tool on and off and for selecting between 3 stages.
The air volume is varied in the three stages from 150/300/500 l/min.

At stage 1 of the sliding switch (4) the temperature is always 50 °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 (11).
The numbers 1 – 9 shown on the adjusting wheel are used for orientation. “1” means 50 °C. “9” means 600 °C (maximum temperature).

metabo H 16-500 Hot Air Gun 1

HE 23-650 Control
The sliding switch (4) can be used to switch the tool on and off and for selecting between 2 stages.
Setting temperature:

At stage 1 of the sliding switch (4) the temperature is always 50 °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.

Press the buttons (6) to set the temperature.
Briefly press the “+” /”-” buttons to increase or lower the set value in 10° steps. Press the buttons longer to change the value faster.

Notes:

Triangles are displayed when the desired temperature is being set.
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 triangles flash during this period.

The actual temperature is measured at the nozzle outlet. The triangles disappear when the desired temperature has been reached.
When the hot air gun is switched off, the last value set is retained.

Setting air volume:
Press the buttons (7) to set the air volume or the 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. A for program 1 appears in the display. Press the program button again to reach 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
(For 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 program button “P” until the program to be changed is displayed. Set the desired air volume and temperature. Then push the save button (10) until the symbol in the display disappears (approx. 5 seconds). The entered values are now saved in the program.

Note:

To return from program operation to the normal function, press the program button (8) until the program symbol in the display (9) has disappeared.
The factory settings of the programs are listed in chapter12..

Stationary operation
If you wish to use the hot air gun 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).

Servicing
The air inlet (3) with grid must be free of foreign bodies. Clean the air inlet (3) if necessary.

Troubleshooting

Thermal protection
The tools are equipped with 2-stage thermal protection:

A thermo switch switches off the heater in case of excessive interference in the air outlet of the blow-out 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 thermo 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 blow-out opening is reached.

does not apply to HE 20-600, H 16-500 2. The thermal fuse switches the tool off completely in the event of overloading.

Short-term voltage drops
Switching on the machine reduces the voltage briefly. Unfavourable mains power conditions may have a detrimental effect on other machines. Network impedances less than 0.4 ohms should not cause malfunctions.
