Residual Heat Indicator - STEINEL PROFESSIONAL HG Roof Manual Del Usuario

Safety precautions
Operation only under
supervision.
Constantly watch the tool while it
is in operation. Heat coming from
the tool can set alight combustible
materials in its proximity. The tool
must only be used by trained spe-
cialists or under their supervision.
Personal protection
While working with the machine,
wear your personal protection gear
(e.g. protective gloves, work shoes
etc.)
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.
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 tempera-
ture 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. Responsi-
bility 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 mm² 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 roof 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 temper-
ature.
• Make sure the welding temperature is reached before you
start to work (the tool takes 3 to 5 minutes to heat 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 weld-
ing 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 heat-
ing 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 (H) 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 speeds up the tem-
perature setting process. Once the required temperature has
been set, the tool takes a few seconds to reach temperature
(depending on the airflow rate selected). 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 tempera-
ture 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 tool 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.
P
Programming mode
Four programs are factory-set for the most common types
of work. Press button "P" (G) for programming mode. Num-
ber 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.
S
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 mem-
ory symbol on the LCD flashes to indicate that the user
