Care must be taken to ensure that the preheat nozzle provides intensive and uniform preheating
(melting) of the base material over the entire joint width at as low a hot air temperature as possi-
ble. For larger weld seam widths, a wider preheat nozzle is available as an accessory.

Starting the hand extruder
Observe section “Safety“.
•
Never operate the hand extruder without air supply. Otherwise the unit may suffer
severe damage.
•
Before plugging in the mains connector, check that the drive unit is not set to
continuous operation.
•
The hot air hood (128) must be mounted to the heat guard (115) of the hand ex-
truder melting chamber.
•
Plug in mains connector.
•
In the case of the hand extruder with integrated air supply, the blower must start
automatically.
•
Once air exits the preheat nozzle (4), the heating systems for the air/melt tem-
peratures may be activated.
•
For the operation of the temperature controller, see section 5.5 ”Set temperatures“. For tem-
perature settings, see page 28.
The hand extruder will reach its operating temperature after about 10 to 15 minutes.
