Check pre-tightening of the stud and tighten by wrench, if loosened.
Clean studs, nuts and around seats.
Screw the nut manually until the nut contacting the seat closely.
Check condition of the hydraulic tool set and make them ready to use.
Mount support (extension screw) and screw the jack by hand.
Connect hoses from the pump to the jacks via the distributing piece.
Close the release valve of the hydraulic pump.
Open air venting plug of the jack and check air venting by pumping.
Close the venting plug and pressurize up to the specified pressure for tightening the nut.
Turn the nut to be screwed firmly by a pin manually through the hole of the support.
Release the hydraulic pressure by opening the release valve of the hydraulic pump.
Repeat pressurizing and check the nut loosened.
Retighten the nut, if loosened.
If the stud or nut has been replaced by new ones, repeat the tightening three times for the first tightening. This repeat is necessary for
the settlement of the threads.
Release the hydraulic pressure and dismount the tool set.

While opening a hydraulic nut, don't forget to unturn the piston Jack by more than one and quarter turn. Otherwise the jack will get stuck coz the bolt will regain its original length but you didn't left any gap between spacer and piston assembly.

Hey thank you soo much, love your videos. I was hoping that you could clear one doubt, if you have the time. What is the purpose of controlled air in Hydraulic tool removal unit. ( The one you said we should depressurize while releasing the Jack's pressure)

Control air is for the pump without air you cannot work the pump always adjust control air from 6 to 7 kg per square centimeter.

@@Adventure-Story thank you, we used hand operated hydraulic pump, so we didn't have control air. So I got confused. :)

My friend u said on other video that when tightening nut. You dont need to turn back 1 or 1/2 turn open the jack. But in this video the operator made a turn back open.. Im so confuse in this, because i work with alot of people others when tightening they always said also to nake turn back open..kindly explain this.. Thanks..

Hello dear friend! Normally for tightening only tight not any turns or little bit no matter maybe he makes it to be sure that hydralics will be easy to remove by hand later on.
