1. ASSEMBLY
1.1 Lightly lubricate the bottom and the wall of the location bore of the TWA as well as the thread of the setting screw
with MOS2 assembly paste.
1.2 Enter the hexagonal key through the wedge into the hexagonal socket of the setting screw and insert together into
the location bore of the adjustment unit to the bottom of the bore. (fig.1).
1.3 Using hexagonal key push setting screw into the radial recess at the bottom of the bore and screw-in the wedge
anti-clockwise into the location bore to the block. In doing so the cartridge contact surface must be positioned
opposite to the radial recess. Push the wedge from above onto the setting screw, so that the thread of the wedge
can thread onto the setting screw (fig.2). If when screwing in the wedge the setting screw collar “jams” in the
location bore (noticeable through the threaded pin being difficult to turn), press the entire adjustment unit into the
location bore with the hexagonal key, if necessary resolve “jam” via clockwise rotation.
1.4 Lightly lubricate cartridge contact surface on the threaded key and the cartridge clamping screw thread with
MOS2 assembly paste and screw in the cartridge clockwise into the cartridge seat with the cartridge clamping
screw.
1.5 Screw in the indexable insert into the indexable insert seat of the cartridge (see tightening torque indexable insert
clamping screws).
1.6 The disassembly is carried out in the reverse order.
2. OPERATION
2.1 Using key lightly tighten the cartridge clamping screw in a clockwise direction to the smallest dia. setting.
2.2 Adjust taper or diameter respectively via the TWA adjustment (fig. 7), whilst doing so move to within 0.05 mm in
diameter of the setting dimension of the indexable insert (if necessary loosen cartridge clamping screw again).
2.3 Using key tighten cartridge clamping screw in clockwise direction (see tightening torque for cartridge clamping
screws.
2.4 Adjust indexable insert setting dimension via TWA adjustment, if the dimension is exceeded simply loosen the
TWA again and re-adjust.
2.5 If required lubricate the contact surfaces and the thread of the TWA adjustment unit.
