24 — the Bolt, 10 Nanometers

Turn out both back bolts of fastening of the pallet of a case (1) and (2) face key (address an illustration above). For this purpose at cars about the manual check point turn a flywheel (3) so that the groove (the arrow on an illustration is lower) was opposite to the screw.

Back bolts of fastening of the pallet of a case

Preliminary tightening bolts with (1) on (18) is made cross-wise by the moment of 5 Nanometers and further the moment of 45 Nanometers. M10 bolts (shooters on an illustration are lower) drag on the moment of 40 Nanometers. Bolts with (1) on (18) cross-wise the moment of 15 Nanometers.
