Work step: Inserting sections 1 to 3:
Before inserting the secstions, ensure that the interior is clean and that the
cylinder tube is thinly coated with hydraulic oil. Never insert the sections into
the pit jack by hand. Always use suitable lifting gear!
1
When inserting in the groove ring area (on the piston), ensure that the
groove rings do not come into contact with the thread of the cylinder barrel.
This also applies to all other levels!
2
Starting with the largest section, insert all sections into the pit jack one after
the other. Make sure that the screw plugs on the largest and smallest guide
bushes are not fitted. (The screw plugs on the pit jack for draining the oil
are open!)
3
When inserting the sections, ensure that the groove rings in the pistons are
generously coated with hydraulic oil!
4
Using a lifting device, position the cylinder tube or piston rod including
guide bushing, piston and installation wrench on the eyebolt above the pit
jack and carefully insert it into the pit jack. To make it easier to screw in the
guide bush, do not lower the sections completely into the pit jack.
