Care and Maintenance
To ensure that the welding machine functions properly, observe the following maintenance rec-
ommendations:
The guide rods must be kept free of dirt and grime. Replace guide rods whenever surface
shows signs of erosion or damage, otherwise hydraulic system may loose pressure.
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 detergent with one Ethanol content >99.8%
(according to DVS 2207) (heating plate must be cool!).
Change hydraulic oil (HLP – 46, no.: 53649) every twelve months.
To avoid malfunctions, regularly check the hydraulic unit for leaks, proper fit of connections
as well as the power cable for signs of damage or wear.
Protect the fast-on couplings on both the hydraulic unit as well as the hydraulic hoses from
dirt and grime. Remove any dirt or foreign objects prior to connecting.
The trimmer unit is equipped with two bi-directional blades. Rotate or replace blades when-
ever trimming performance is no longer up to expectations.
Always ensure that the pipe and workpiece ends, in particular the butt surfaces are clean.
Dirt or other foreign substances will shorten the serviceable life of the blades considerably.
Pursuant to welding guidelines the welding machine must be inspected annually by the
manufacturer or an authorized service workshop. Machines subjected to above aver-
age use or strain should be inspected at shorter intervals!
