Damage to the mains power cord.

If this tool's main power cord is damaged, it must be replaced by the manufacturer or its customer service department or a similarly qualified person so as to avoid hazards.

Residual heat indicator

The residual heat indicator serves as a visual warning to prevent injury from direct skin contact with the hot nozzle outlet. The residual heat indicator also works when the tool is unplugged. 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: always try out the airflow and temperature on a test piece first! Take care when changing hot nozzles! When using the automatic hot air welding machine, make sure that the base surface is clean. Switching ON causes brief voltage drops. If the mains power supply system is not absolutely stable, other equipment may be affected. No malfunctions are likely to occur with mains impedances of less than 0.35 ohms.

Proper use

Electric power tool for overlap welding roof membranes on flat roofs Only use genuine STEINEL replacement parts and accessories as you will otherwise not be able to make any warranty or guarantee claims.

Getting started

Power cord and extension cable

- The mains voltage must match the rated voltage (→Technical specifications) specified on the tool.

- The mains power cord must be able to move freely and hinder neither user nor third parties in their work (risk of tripping over).

- Extension cables must be approved for the place of use and marked accordingly. Take into account any minimum cross section needed for the extension cable.

We recommend extension cables with a cable cross-section of 2.5 mm ^2 and a maximum length of 50 m. Restrictions to maximum temperature must be expected if cables of other sizes are used.

- Hook the mains power cord into the eye on the telescopic handle to avoid running the machine over the cable.

Positioning the tool

- Make sure that the material being welded is clean between the upper and lower surface of the overlap.

• Then make sure that welding nozzle

pressure roller and downholder are clean.

- Move the hot air tool into parked position.

- Now raise the automatic hot air welding machine by means of the telescopic handle and move the tool to the welding position.

- Now position the root membrane and then lower the downholder.

Starting the tool

- Once you have prepared the work area and the automatic hot air welding machine, connect the automatic hot air welding machine to the mains power supply.

- Switch the automatic hot air welding machine ON via the "mains ON/OFF switch".

- Switch ON the barrel-type hot air tool.

- Set airflow rate and temperature.

- Machine heats up to the selected settings.

Welding process

Preparing to weld

- As soon as you have switched on the heating element, you will see a dynamic display of the current air temperature.

- Make sure the welding temperature is reached before you start to work (the tool takes 3 to 5 minutes to heal up).

- Now make test welds in accordance with the welding instructions of the material manufacturer and/or national standards or guidelines, and check the results. Adjust the welding data if necessary.

Starting to weld

- Turn the hot air tool inwards and insert the welding nozzle in between the overlapping membranes as far as it will go.

- The automatic welding machine immediately sets off (automatic start-up system).

Guiding the machine during the welding process

• Guide the automatic hot air welding machine by the telescopic handle along the overlap, always paying attention to the position of the downholder.
• Avoid pressing on the telescopic handle during the welding process as this may result in welding flaws.

Finishing welding

- Turn the hot air tool outwards. The automatic welding machine stops immediately.

Switching OFF machine

- On the hot air tool, switch the heating element OFF so that the welding nozzle can cool down.

Note: press ON/OFF for several seconds and the machine will go into cooling mode. Cold air is blown through the heating element and the nozzle for 5 minutes. The hot air tool switches off automatically after 5 minutes.

- Now switch the machine OFF at the main switch and disconnect the mains power cord from the mains power supply.

• Wait for the machine to cool down!

- Check the mains power cord and the plug for electrical and/or mechanical damage.

- Clean the welding nozzle with a wire brush.

Setting the temperature

Temperature can be adjusted over a range of 50-620°C by the joystick on the control panel with LCD display. The actual temperature is measured at the at the outlet nozzle and indicated on the display. The joystick (HI) is used as an input button with plus/minus function. Briefly pressing the "+/-" joystick increases or reduces the temperature setting in 10° steps. Keeping the joystick pressed spaces up the temperature setting process. Once the required temperature has been set, the lock takes a few seconds to reach temperature (depending on the airflow rate selected). The temperature setting solicited is shown on the display for 3 seconds. The display then shows the current actual temperature. The "CCP" symbol continues to flash until the selected temperature is reached. If you want to alter the setting, simply move the joystick again to increase or reduce the temperature. After switching OFF, the hot air too stays in the last setting.

Setting airflow rate

To change the airflow rate, first press the button for airflow mode (I); the fan symbol flashes. Now use the joystick to set the airflow 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.

Programming modeF

Four programs are factory-set for the most common types of work. Press button "P" (Q) for programming mode. Number 1 is displayed for program 1. Continuing to press the program button will take you to programs 2-4. Pressing the button again will return the tool to normal operation.

Memory function

The values selected for the four programs can be changed and memorised at any time. First press the program button "P" (G) until the display shows the program you wish to change. Set the chosen air flow and temperature. The memory symbol on the LCD flashes to indicate that the user

program selected has been changed. To save this setting in the user program selected, press and hold down the program 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 program button until the program symbol disappears from the display.

Adjusting the tool for using Resitrix roof-sealing membranes

On leaving the factory, the HG Roof automatic welding machine is configured for welding various brands of PVC and FPO / TPO roof membranes.

To use root membrane from Resitrix, you must change the machine setting as follows:

1. Raise downholder (P)

2. Undo fastening screw on spacer wheel (N)

3. Turn spacer wheel so that it shows "Resitrix"

4. Re-tighten spacer-wheel fastening screw

This change at the downholder (P) also makes it necessary to change the position of the welding nozzle (M):

1. Undo clamping screw below the guide carriage (O)

2. Set hot air tool so it can be moved inwards

without a problem (when moving it inwards, nozzle must not be allowed to contact the upper roof membrane) 3. Re-tighten clamping screw

This adjustment is necessary so as to produce a weld (welding bead) during the welding process. A simple visual check instantly shows you whether you have produced a permanent and watertight joint.
