Fig. 2.256. Connecting plate of a natyazhitel of a chain

Slowly take away a plunger back in the direction shown in the figure 2.256, at the same time the connecting plate has to remain drowned.

Release a connecting plate at the pressed plunger.

Weaken pressure upon a plunger a little and move a plunger back and forth on 2–3 mm.
