To unlock the lock, turn the lock counterclockwise until it stops and a wrench-a screwdriver through the holes in the locking mechanism to rotate alternately the pins on the number of half-turns, corresponding to the code of the lock from the extreme position in which they were moved when locking in the “open” position. After that, remove the key, turn the lock clockwise by 90° and remove the pin from the housing. The latch performs the role of the blocking device, excluding unlocking the contact pins and locking elements and pins, so the lock code will fail to pick up on the touch.

THE MANUFACTURE OF THE LOCK
To carry out turning machining of the pin (steel 40X) in the drawing (Fig.4).
To handle the front and the cylindrical surface of the workpiece (steel 20) under the body (Fig.Z).
By the end of the boring cutter with a stationary spindle, using longitudinal and cross-feed, hold the line marking on cylindrical (a) and frontal (diameter) treated surfaces.
To remove the chamfer.
To cut the workpiece of the body in size.
To lay out and stake the centers of the following holes: 12 mm — cuts of n. Z and a diameter of 4 mm on the cylindrical surface; a diameter of 8 mm and a diameter of 6 mm (2 ed.) — on the front; M14 — on the rear surface.
To drill radial holes: 12 mm — depth 43 mm, rassverlit it then under the diameter of 20 mm to a depth of 9 mm and a diameter of 4 mm at a depth of 10 mm, as well as the end: with a diameter of 6 mm (2 ed.) with a depth of 10 mm and under the threads of M14.
Insert into the hole with a diameter of 12 mm steel rod technology (not to have withdrawn the drill bit), hold the cartridge housing with eccentricity and drill the end hole with a diameter of 8 mm to a depth of 30 mm.
To perform a counterbore in the end of the body diameter of 29 mm and a depth of 6 mm.
Drill through hole under the M4 thread in continuation of the radial holes with a diameter of 4 mm.
Cut thread M4, M14.
Insert the pin into the housing until it stops, to deepen one hole of 6 mm in diameter in the body up to 21 mm (from the plane of the bore).
To fix the pin in the case of the technological core of 6 mm in diameter, inserted in drilled according to claim 12 hole, and deepen the second hole with a diameter of 6 mm to 21 mm.
Drill a continuation hole with a diameter of 6 mm in the housing through hole М6х0,75.
Cut thread М6х0,75 the two holes (fine thread is selected to increase the secrecy of the castle).
Processing the portion of the pin with a diameter of 12 mm width 5.5 mm; a flat surface perpendicular to the axes of the recesses obtained in PP. 12,13.
To bring the radius grooves up to 4 mm (for protection selection of the code); to cut a rectangular slot in the dimensions indicated in Fig.4.
To make the clip (steel 40X) in the drawing (Fig.6).
Carve a two piece pin (steel 40X) in the drawing (Fig.7).
To penetrate the cylindrical portions of the pins in random places on a single groove (Fig.8) so that the inclination of the slot to the flat bottom of the groove was the same on both pins. This is to ensure that both dowel pins were “discovered” in the same angular position of the key.
Screw the pins into the housing so that the grooves located in the middle of the hole for the pin and formed a passage for him.
Insert in the housing, the locking mechanism until it stops and turn the groove to the hole for the pin. Insert the pin into the housing recesses to the pins until they stop to check whojust pin in “open” position of the lock mechanism. If you need to adjust.
To check capture pin lock, which rotate past 90° counterclockwise. The pin should be stationary fixed in the housing.
To make a key blanks (steel wire 3 mm in diameter) in the drawing (Fig.5).
Sharpen the end of the key under the screwdriver so the angular position of the blade to the ring is inserted into the key slot located in the plane of the holes 6 mm in diameter (see section a-A in Fig.1). When fitting key to lock the pins in “open” position by inserting a pin (in the absence of the retainer) in the case Vice versa, that is, the notches from the pins.
Insert the locking pin. Glands and loosen the half-turn screw (Fig.1).
To determine the lock code, which by checking the “open” position lock (see p. 22), remove the pin and by turning the latch by 90°, alternately install the key pins until they stop, counting the half-turns of the key, including incomplete. The number of half-turns of each pin will be his code. You can do the same, wrapping the pins until it stops, taking in this case as a starting point the extreme inverted position.
To check the correctness of code, which to turn (screw) pins the number of half-turns, corresponding to the code, with the last twist key ring to Orient in the plane A-A (it is easy to do on the “peg” in the center of the disk retainer that is designed for the orientation of the ring key on the touch unlocking the lock in the dark), before removing the key; turn the latch 90° to the groove to the hole and insert the pin into the housing. If the pin is inserted until the end (you can check secure it as in section23), then the lock code is defined correctly and it is necessary to record it in a hidden place and remember.
Disassemble the lock, thermally treating the pin, pins and retainers to the hardness of LDCs 46…50; on the housing, pin and latch to cause the zinc coating; to lubricate parts with grease; finally assemble the lock for its operation.
