2.2 Fastening to the high-pressure lance
It is recommended that a torque wrench be used when fitting a nozzle onto a lance. The
required tightening torque is 70 Nm.
Rotary nozzles must always be unscrewed from the lance before servicing them.
Check the high-pressure threaded screw connections for cleanliness and apply metal
lubricating paste to them before fitting.
1. Slide the M26 pressure screw onto the lance.
2. Screw the thrust ring onto the lance (left-hand thread). Screw the thrust ring onto the
lance to the full extent of its threaded area.
3. Insert the lance cone into the Tango nozzle's counter-cone.
