Operating Instrustions
3.2 Temperature Adjustment
The unit has been preset at the factory to an operating temperature of 200°C.
The temperature can be adjusted at the temperature regulator (3) easily by hand. Turning the
adjusting screw clockwise increases the temperature; turning it counterclockwise decreases the
temperature.
3.3 Adjustments on the Unit
The stroke limiter (7) can be used to repeatedly extrude precisely metered amounts of
glue. Set the required amount of glue with the aid of the stroke limiter (7).
The stroke limiter can also be used to adjust the comfort of trigger (4) action.
3.4 Notes on Gluing
The surfaces being glued should be at room temperature and be free of dust, grease, and
moisture. Materials coated with or containing wax, separating oils, plasticizers, or impregnation
agents may cause the bond to come apart immediately or at a later date.
Apply the hot melt adhesive in either dot or bead form. Large dots retain their adhesive strength for
longer than small ones. Firmly press the materials together straight away for several seconds.
Slow, continuous extrusion will ensure that the glue does not fall below application temperature.
3.5 Breaks / End of Work
If no glue is required for longer than 20 – 25 minutes, switch the unit off at the power switch
(5). The glue stick can remain in the unit for re-melting when the glue gun is used next time.
3.6 Changing the Nozzle
Special nozzles are available for special tasks.
To change the nozzle, the unit must be warm but disconnected from the power supply.
Wear heat-protection gloves to hold the unit.
Unscrew the nozzle (1), being careful not to pull the trigger.
Screw on the new nozzle hand-tight.
