5 MAINTENANCE
5.1 SHEATH REPLACING
Before assembly, the metal sheath must be cut precisely:
• Put the PUSH PULL torch in position in order to have it as straight as possible.
• Loosen the nut, remove the teflon sheath and insert the metal one.
• As the sheath is longer than the torch, X mm protrude (see fig. 1).
• Measure precisely the length of the protrusion (see fig. 1).
• Length of the sheath in the torch ≈ 4 150 mm.
• Remove the sheath, and cut to size part. Use only a very sharp tool in order to avoid burrs which could block the the
wire way (see fig. 3).
• Cut the end of the liner into a point.
• Shape the tip of the liner so that it is straight.
• Insert the prepared sheath.
• Re-tighten the screw
• Replace the contact tube.
