In the event of doubt, consult the pipe manufacturer for material-specific welding parameters.
The welding parameters specified in the welding tables are strictly reference values. ROTHEN-
BERGER cannot assume any liability for their accuracy or completeness!
4 Care and maintenance
To ensure that the welding machine functions properly, observe the following maintenance rec-
ommendations:

Keep the guide rods for the skids or for the heating element holder and milling unit free of
dirt.

The electric drives of the trimmer and heating element must be operated only with the volt-
age stated on the type plate.

To achieve perfect welding results, it is essential to keep the heating plate clean. If the sur-
face is damaged or shows signs of erosion, the surface must be recoated or replaced. Mate-
rial residues on the heating plate surface reduces the non-sticking properties of the coating.
Remove all residues with non-linting paper and alcohol (heating plate must be cool!).

The trimmer is equipped with two double-sided ground knives. When cutting capacity starts
decreasing, the knives can be turned over or replaced by new ones.

It must always be ensured that the pipe or workpiece ends to be machined, especially the
face surfaces, are free of soiling because otherwise the service life of the knives will be
shortened.
It is recommendable to have repairs done only by a service workshop or by
the manufacturer!
4.1 Machine and tool care
(Follow the maintenance instructions in item 4!)
Sharp and clean tools produce better work results and are safer.
Replace blunt, broken or lost parts immediately. Check whether the accessories are securely
connected to the machine.
Use only original spare parts from the manufacturer for maintenance work. Repairs must be car-
ried out only by professionally qualified personnel.
Disconnect the machine from the mains when it is not in use, prior to care and maintenance
work and before changing accessory parts.
Prior to reconnection to the mains, it must be ensured that the machine and the accessory tools
are switched off.
When extension cables are used, they must be checked for their safety and operativeness. Only
cables approved for outdoor use must be used.
Tools and machines whose housing or handles, especially those made of plastic, are cracked or
warped must not be used.
Dirt and moisture in such cracks conduct electric current. This can lead to an electric shock if the
insulation is damaged in the tools or in the machine.
Note: Furthermore, we refer to the accident prevention regulations.
