The air filter is to be cleaned as necessary.
• Detach the countersunk screw (26, A).
• Remove the chromium steel cover (26,
B).
• Remove the filter mat (26, C) and rinse
the mat under cold water.
• Blow down and dry the filter mat with
compressed air.
• Re-fit the filter (70), cover (60), and
screws (100).
The filter must be replaced every two years.
12.3 Machine Fault
Machine blockages can occur if the weld material is not lead downstream of the welding zone unimpeded. If a machine
fault/blockage occurs during the welding process, end the weld immediately with the left-hand pedal (7A) of the
pedal
unit (7)
.
If a hazardous situation arises, switch off the machine immediately with the emergency stop button
(12).
Set the sliders in the "Periphery" area to "Manual" so the wheels are opened. Carefully remove the material causing
the blockage.
Good wheel positioning is very important to ensure good contact between the wedge, weld material, and wheels. If
you are getting poor welding results even though the wedge is positioned correctly, check the running of the wheels.
Contact your Leister sales partner for more information about the arm settings.
