Safety precautions
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 (battery, 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. Always hold the tool on the plastic housing. Be aware that the metal nozzle is hot when the power tool is switched on and, after the tool is switched off, needs around 20 minutes to cool to a point when it can be touched. Do not touch the nozzle or accessory tips until cool. Children should be supervised to make sure they do not play with the tool.

Repairs by a qualified electrician only

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.
Battery
- Protect the rechargeable battery and the tool from heat, moisture, water, e.g. also from continuous sunlight and fire. Risk of explosion!
The rechargeable battery must only be removed as described in these instructions.
Do not open the tool or the rechargeable battery. This could cause a short circuit. In the event of problems, contact your retailer.
Do not touch any electrolyte fluid that has escaped. Do not get electrolyte fluid in your eyes. Immediately move tool away from naked flame or sources of heat. Immediately remove contaminated clothing.
If electrolyte does escape from the battery, the following action is necessary:
Contact with eyes
Immediately rinse eyes with copious quantities of clean water, such as tap water, but do not rub. Seek medical attention. Failure to take the appropriate action can result in loss of sight.
Contact with skin
Immediately wash the areas affected with copious quantities of clean water, e.g. tap water, or skin irritation may occur. If the chemical penetrates clothing, take off clothing immediately and wash the skin with water. If irritation persists after washing it off, seek medical attention.
Inhalation
If the rechargeable battery is damaged or used improperly, vapours or electrolyte fluid may escape. Provide fresh air and seek medical attention if you feel unwell or discomfort occurs. The vapours may cause respiratory irritation.
The lithium-ion rechargeable battery can be recharged at any time without shortening its lifespan. Interrupting the charge cycle will not damage the rechargeable battery.
If the tool is not going to be used for a prolonged period, remove the rechargeable battery from the tool. This will prolong the life of the lithium-ion rechargeable battery.
When not in use, keep the rechargeable battery away from paper clips, coins, keys, nails, screws or other small metal objects that could short-circuit the contacts. A short circuit between the rechargeable battery contact may result in burns or fire.
- Do not short-circuit the rechargeable battery. Risk of explosion!
■ Make sure the tool is switched off before you insert the rechargeable battery. Inserting a battery into a power tool that is switched on can result in accidents.
Only charge the batteries in chargers that are recommended by the manufacturer. A charger that is only suitable for charging specific batteries presents a fire risk if it is
used for charging other batteries. Use only those rechargeable batteries in power tools which are intended for them. Use of other rechargeable batteries may result in injuries and fire hazard.
- Protect the rechargeable battery from moisture and water. Only store the rechargeable battery in a temperature range of 0 °C to 45 °C. For example, do not leave the battery inside a car in summer. Occasionally clean the rechargeable battery's ventilation slots with a soft, clean and dry brush.
- Only use genuine ProCORE and genuine ProCORE chargers.
Recommended battery capability is 8 Ah or higher.
The running time of the device can be decreased if the battery was used shortly after recharging and was still warm.
Transportation
To transport the tool, remove the battery pack.
Transporting li-ion battery packs
Shipping a li-ion battery pack is subject to regulations on the carriage of dangerous goods (UN 3480 and UN 3481). When shipping li-ion battery packs, ascertain the regulations currently in effect. If necessary, obtain information from your carrier. Certified packaging is available from Steinel.
Only ship battery packs if the housing is intact and not leaking any liquid. For shipment, remove the battery pack from the machine. Insulate the contacts to prevent short-circuiting (e.g. with adhesive tape).
Outlet nozzle, nozzle attachment and air delivery can reach a temperature of over 550 degrees Celsius!
Beware of burns! After skin contact with hot materials, immediately cool with cold water. If necessary, seek medical attention.
Keep these safety precautions with the tool.
Proper use
STEINEL mobile heat cordless hot air tools are intended for shaping and welding plastic as well as for heating shrink tubing. It is also suitable for soldering, tin-plating and un-doing bonded joints.

Startup
Battery pack
Charge the battery pack 8 before use. Recharge the battery pack if performance drops. The ideal storage temperature is between 10 °C and 30 °C. The permissible charging temperature is between 0 °C and 50 °C.
The rechargeable battery switches off at a temperature over 70 °C and remains switched off until it returns to the optimum temperature range.
"Li-Power, LiHD" li-ion battery packs have a capacity and signal indicator 9:
-Pressbutton 10 and the state of charge is indicated by the LED lights (the power tool has to be switched off at least 1 sec).
- If an LED light flashes, the battery pack is almost drained and needs to be recharged.
The tool's output capacity depends on the rechargeable battery that is selected. To utilise the tool's full output capacity, we recommend using genuine ProCORE battery with the capability 8 Ah or higher.
Rechargeable battery state-of-charge indicator
The five green LEDs on the battery state-of-charge display indicate the rechargeable battery's state of charge ⑨. It is only recommended to check the state of charge when the power tool has been switched off at least 1 sec or disconnected.
Press button 10 to display the state of charge (can also be done with the rechargeable battery removed).
The state-of-charge display goes out automatically after approx. 3 seconds.
Inserting rechargeable battery
From the front, slide the charged battery 8 into the base of the hot air tool. Push the rechargeable battery all the way into the base until it clips into place.
Switching on the tool
Use the ON/OFF switch.
Removing, inserting battery pack
Removing: press button 7 to release the battery pack and detach battery pack 8.
| LED Capacity | |
| Permanent light 5 × green ≥ 4/5 | |
| Permanent light 4 × green ≥ 3/5 | |
| Permanent light 3 × green ≥ 2/5 | |
| Permanent light 2 × green ≥ 1/5 | |
| Permanent light 1 × green < 1/5 | |
| Flashing light 1 × green Low battery | |
If no LED lights up after pressing button 10, the rechargeable battery is faulty and must be replaced.
Getting started
The tool can be switched ON and OFF by the main switch. The output temperature can be set via the setting wheel. The air flow is adjusted automatically depending on the battery status, ambient conditions and the type of the output nozzle. The main goal of automatic air flow regulation is to achieve the highest possible flow values at a constant outlet temperature and thus ensure maximum output power for all situations.
Setting wheel for output temperature
For the output temperature setting is used setting wheel. Temperatures can be set in the range of 150 - 550°C with a step of 50°C for each number. The numbers 1 - 9 are printed on the wheel.
| Number on the wheel Output temperature °C | |
| 1 150 | |
| 2 200 | |
| 3 250 | |
| 4 300 | |
| 5 350 | |
| 6 400 | |
| 7 450 | |
| 8 500 | |
| 9 550 | |
Status LED light
A status LED light is located under the temperature setting wheel. If the MH-7 is switched ON and the set temperature is not reached, the wheel flashes slowly. If the outlet temperature is reached, the wheel lights up continuously.
When the LED light flashes fast, the device stops immediately. Fast flashing indicate one of the following situations:
• the battery is empty - replace the battery
- the battery is defective or not compatible - replace the battery
- the battery was connected when the main switch was turned ON - turne the main switch OFF and ON again
If the user does not take any action within two minutes after fast flashing starts, the LED will stop flashing and the device will automatically turn off.
