Putting into operation

Please read through the operating instructions and safety instructions atten-
tively before you put the butt fusion welding machine into operation!
Do not use the heating element in explosive environments or bring it into
contact with easily flammable materials!
 Open the 4 locks and lift the upper part of the transport box and turn it around. Put the ma-
chine on a level, solid surface.
 Put the machine, which is mounted on the base of transport box onto the opening of the up-
per part of the transport box.
 Turn the handle bar into the pressure lever joint (frontside of the machine) and loosen the
knurled handle for fixing the table.
 Pull the trimmer lock to the front and swivel the trimmer to the back.
 Swivel heating element to the back and turn the handle bar into heating plate holder.
 Connect power plug of trimmer unit and heating element to the power supply stated on the
type plate.
The red diode "Stand by" lights up. That is: there is a voltage being applied. Switch on the heater
element using the large pushbutton (lights up green) and select the desired temperature (160°C
to 285°C) using the "+" or "-" button.
Heating up of the heater element is displayed by a yellow diode on the heater element. A hori-
zontal bar also appears on the temperature indicator. The yellow diode goes out shortly before
reaching the set temperature (tolerance +/-3°C) and the green one lights up. After a further 10
minutes the heating element is ready to use. Check the temperature using a temperature meas-
uring instrument.
Setting the off-set: press the "+" and "-" button at the same time. The heater element can subse-
quently be calibrated using one of these buttons and an external temperature measuring instru-
ment.
If the heater element displays a smaller value than that on the external temperature measuring
instrument then the difference must be adjusted using the "+" button. For indicated values in the
other direction adjust the difference using the "-" button. If "Er1" appears it means that the elec-
tronics are defective. "Er2" means that the resistance thermometer is defective or not connected.
Very hot – Do not touch! The heating element can reach a temperature of
approx. 290°C!
