Each position is precisely marked by a notch. This process is clearly marked on control knob as; IFT TURN SWITCH ON (can be engraved in any language) Current Contact inner dia.

Fixing nut The notched end of the shaft (1) is to be fitted into the slot inside the lid. Press the lid onto the shaft, turn it 90 and release. The lid will be locked automatically. To dismantle the lid, apply the assembly operation in reverse order. max. 10 mm Ø20H12 8. Control device body (Nylon) 9. Spring 10. Control device lid Oring 12. Control device cover 1 1. Shaft Fig. 2 Position Changing Mode Normally Rest Mode 8 In order to change the position of the tap changer, pull the control device body (8) along the direction of the arrow, turn it to the desired position notch and release. The spring system will automatically lock the position via position stopper and position notch an the body. Notes For the assembly of the tap changer, the thickness of the transformer cover is assumed to be 10 mm. If the cover thickness is lower than 10 mm the additional spacer washer () can be used to accommodate up to mm (1 mm per spacer washer) of the transformer cover thickness. The resulting thickness is to be 10 mm. For example if the cover thickness is mm, washers are to be used to balance the difference of mm. If the cover thickness is 10 mm there is no washer needed.
