Instruction Manual

Translation of the original operating instructions
Please familiarise yourself with these operating instructions before using this product because of prolonged reliability and the trouble-free operation will only be ensured if it is handled properly.
We hope your new hot air tool will give you lasting satisfaction.

Safety warnings

Read and observe this information before using the tool. Failure to observe the operating instructions may result in the tool becoming a source of danger.
When using electric power tools, observe the following basic safety precautions to avoid electric shock as well as the risk of injury and fire.
Used carelessly, the tool can start an unintentional fire or injure persons.
Check the tool for any damage (mains connection lead, housing, etc.) before putting it into operation, and do not use the tool if it is damaged.
Do not leave the tool switched on unattended.
Children should be supervised to make sure they do not play with the tool.

First time of use
A small quantity of smoke may occur when the tool is used for 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 time.
Any smoke coming out of the tool is not harmful!

Take the ambient conditions into account.
Do not expose electric power tools to rain. Do not use electrical power tools when they are damp or in a damp or wet environment. Exercise care when using the tool in the proximity of flammable materials. Do not direct the tool at one and the same place for a prolonged period. Do not use it in the presence of an explosive atmosphere. Escaping heat may be conducted to flammable materials that are hidden from direct sight.

Protect yourself from electric shock.
Avoid coming in contact with grounded objects, such as pipes, radiators, cookers, or refrigerators.
Do not leave the tool unattended while in operation.

Store your tools in a safe place.
After use, set the tool down on its standing surface and let it cool be fore putting it away.
When not in use, tools must be stored in a dry, locked room out of children’s reach.
This tool may be used by children aged 8 or above and by persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they are supervised or have been given instructions on how to use the tool safely and understand the hazards involved.
Do not allow children to play with the tool.
Children are not allowed to clean or carry out maintenance work on the tool without supervision.

Do not overload your tools.
Your work results and safety will be enhanced if you operate the tool wit hin the specified output range.
Do not carry the tool by the power cord. Do not unplug the tool by pul ling on the power cord. Protect the power cord from heat, oil, and sharp edges.
Always ensure that the blow-out tube (including in combination with mounted nozzle) is never completely covered or sealed.
Damage to the heating element or motor may otherwise result.

Beware of toxic gases and fire hazards.
Toxic gases may occur when work ing on plastics, paints, varnishes, or similar materials.
Beware of fire and ignition hazards.
For your own safety, only use ac accessories and attachments that are specified in the operating instructions or recommended or specified by the tool manufacturer.
Using attachments or accessories other than those recommended in the operating instructions or cata Logue may result in personal injury.
Repairs must only be carried out by a qualified electrician.
This electric power tool complies with the relevant safety regulations.
Repairs should only be performed by a qualified electrician. Otherwise, the user may run the risk of accidents.

Residual heat indicator
The residual heat indicator serves as a visual warning to prevent inju dry from direct contact with the hot nozzle outlet. The residual heat indicator also works when the tool is un plugged. 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 temperature. The residual heat indicator does not show if the tool has been in operation for less than 90 seconds.
Responsibility always rests with the user as care must be taken at all times when handling hot air tools.

Keep these safety precautions with the tool.

For your safety
The tool is protected from overheating:
The thermal cut-out completely shuts down the tool if it is overloaded.

Tool description – Operation
Please note The distance from the object you are working on depends on the material and intended method of working.
Always try out the airflow and temperature on a test piece first. Using the attachable accessory nozzles (see accessories page on the cover) the flow of hot air can be controlled with maximum precision.
Take care when changing hot nozzles! When using the hot air tool in the self- resting position, make sure it is standing on a stable, non-slip, and clean surface.
Switch-on procedures generate short-term voltage drops. In unfavourable grid conditions, adverse effects can occur on other devices. With grid impedances of less than 0.35 ohms, no disturbances are expected.

Operation
The tool is switched on and off at the ON/OFF switch 12 on the back of the grip handle. The joystick 10 is used for controlling temperature and airflow or fan speed.
Setting the temperature
Temperature can be infinitely varied over a range of 50-700 °C at the joystick on the control panel with an LCD display. The actual temperature is measured at the hot air outlet nozzle and indicated on the display. The joystick 10 is used as an input button with a plus/minus function. Briefly pressing the “+/–” joystick increases or reduces the temperature setting in 10 °C 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.
Setting airflow rate
To change the airflow rate, first press the button for airflow mode 8; the fan symbol flashes. Now use the joystick to set the air flow rate. The airflow rate setting mode automatically closes if the airflow rate setting is not changed within 5 s. Pressing the airflow button again after setting the airflow rate immediately closes the airflow rate setting mode. The airflow rate can be varied from a minimum of 150 l/min to a maximum of 500 l/min.
Programming mode [P]
Four programmes are factory-set for the most common types of work. Press button “P” for programming mode. Number 1 is displayed for programme 1. Continuing to press the programme selection button will take you to programmes 2-4. Pressing the button again will return the tool to normal operation.
Preset programmes Programme| Temperature °C| Air l/min
---|---|---
1| 250| approx. 350
2| 350| approx. 400
3| 450| approx. 500
4| 550| approx. 400
Memory function [S]
The values selected for the four programmes can be changed and memorised at any time. To do this, first press the programme selection button “P” 9 until the display shows the programme you wish to change. Set the temperature and airflow rate you require. The memory symbol on the LCD flashes to indicate that the user programme selected has been changed. To record 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 s. The settings entered have been saved once the memory symbol stays on all the time. To return to normal operation, press the programme selection button until the programme symbol disappears from the display.
Temperature measurement on the workpiece
Use the STEINEL HG Scan PRO temperature scanner (Prod. No.: 007690) for measuring the temperature at the workpiece.
Heating element
The HG 2520 E hot air tool can be switched off directly after use. There is no need to let the tool cool down after the work process. This does not affect the heating element’s life.
