4. Start the drill, machine the facing surface of pipes/fittings until shavings are turned
out in ribbons which are the same width as the pipe wall thickness. The max.
planer pressure is 10 bar above the drag resistance.
Constant high pressure when facing (15-20 bar over dragging pressure),
can cause damage on the drive and/or the motor of the facer.
5. Release the pressure to Zero by pulling the control lever half way between 0
position and open "<>". With this procedure the pipe surfaces will not show any
offset.
6. Open completely the machine by pressing "open<>".
7. switch off the planer
Remove the planer out of the machine and place it into the case.
8. Close machine until pipes/fittings touch each other.
9. Check the gap between the pipes: Maximum tolerance of the gap is 0.3 mm (d </=
200mm), 0,5mm (200<d<400mm), 1,0mm (d>400mm).
10. Check the alignment all around the circumference.
11. The wall offset on the outside may not exceed 10 % of the wall thickness.
12. If it is larger, the pipe/fitting can be turned or the clamping force on the inner
clamping units can be changed to achieve a better clamping position.
13. In this case, the fusion surfaces need to be remachined.
14. Remove shavings which have fallen into the pipe e.g with a brush. Before each
fusion, the fusion surfaces must be cleaned with lint-free paper and grease-free
cleaner, e.g. industrial alcohol (Tangit KS).
Never touch the fusion surfaces with your hand after cleaning!
Make sure that the pipe/fitting ends reach out at least 30 mm from the
clamps (ECOS 250 -315) in order to perform a proper weld.
Close the carriages till the pipes are in contact with themselves (TM 160).
Control the position of the stroke indicator in relation to the red mark
(cylinder stroke end). If the indicator is close to the red mark, during the
welding procedure no pressure could be transferred into the welding
zone! The weld will not perform !! Change the clamping position of the
pipes! After planning the pipe ends, the distance between the indicator
