Removing, inserting battery pack
Removing: press the button to release the battery pack and detach the battery pack.

If no LED lights up after pressing a button, the rechargeable battery is faulty and must be replaced.

Getting started – mobile heat MH3
The first time the tool is switched on at switch, the temperature factory setting is 300 °C. This can be seen by the LED light under the temperature on the temperature selection display. As soon as the tool is switched on, the heating element is supplied with energy and the motor starts to run, initially at a low speed. For better handling, the mobile heat MH3 is provided with a temperature priority function. This ensures delivery of a constant temperature at all times and controls blower speed in relation to the temperature delivered. To set the temperature to 500 °C, move the joystick to the right. The LED on the right-hand side of the temperature selection display lights up when the temperature reaches 500 °C. To return to 300 °C, move the joystick to the left.

Getting started – mobile heat MH5

The temperature of the mobile heat MH5 can be adjusted with the cordless hot air tool switched off. To do this, press any button on the back of the tool below the display. The temperature can be infinitely varied over a range of 50 °C – 500 °C on the control panel with LCD display. The actual temperature is measured at the nozzle outlet and indicated on the display. The joystick is used as an input button with a plus/minus function. The temperature setting range begins at 50 °C and ends at a maximum of 500 °C. 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 s. The display then shows the current actual temperature. The “°C/°F” symbol continues to flash until the selected temperature is reached. If you wish to alter the setting, simply move 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 “airflow” button; 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 seconds. 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 300 l/min. Depending on battery capacity, the full 300 l/min airflow rate may no longer be reached. If you select a higher airflow rate setting, in this case, the motor will still not run any faster because of the battery’s low capacity. The bars on the LCD will flash to indicate the current airflow rate. In this case, replace the rechargeable battery or charge the battery currently fitted.

Programming mode [P]

Besides normal operating mode, the mobile heat MH5 also has four factory-set programmes for the most frequent jobs. Press button “P” for programming mode . Number 1 is displayed for programme 1. Continuing to press the programme button will take you to programmes 2-4. Pressing the button again will return the tool to normal operation. See page 3.

Preset programmes

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 button “P” until the display shows the programme you wish to change. Set the chosen airflow and temperature. The memory symbol on the LCD flashes to indicate that the user programme selected has been changed. To record this setting in the selected user programme, press and hold down the programme selector button. The memory symbol continues to flash for approx. 2 seconds. The settings entered have been saved once the memory symbol stays on all the time. To return to normal operation, press the programme button until the number disappears from the top part of the display. 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) the flow of hot air can be controlled with maximum precision. A small quantity of smoke may occur the first time the tool is used. Switch the tool OFF by releasing the ON / OFF switch

Hanger
The integrated ring can be used for hanging the tool. Caution: max. pulling force = 150 N
LED light
The LED is lit when the tool is switched ON. In addition to illuminating the area you are working on, it also serves as “tool ON” telltale light.
