3. Lubricating Quill − Function Check
3.1 General
You do a function check to make sure that the non-return valve (1, Fig. 2) operates
correctly. The pressure that opens the non-return valve is 5.0 bar.
During the function check, keep the lubricating quill (2) in a horizontal position.
For the function check, use an oil with a viscosity as given in the specifications that
follow:
D SAE 50 at 40_C (approx. 200 cSt)
D SAE 30 at 25_C (approx. 190 cSt).
3.2 Procedure
1) If necessary, remove the screw-in union on the lubricating quill (2).
2) Connect the HP hose (94935) to the nipple (94934I).
3) Hold the lubricating quill (2) up and operate the pump until oil that flows has no air.
4) Open the relief valve (RV), then decrease the pressure to 2.0 bar.
5) Close the relief valve (RV).
6) Hold the lubricating quill (2) in a horizontal position.
7) Operate the pump and increase the pressure in steps of 1.0 bar until the non-return
valve (1) opens.
8) Record the pressure shown on the pressure gage (94934B).
Note: The minimum permitted pressure to open the non−return valve is
4.25 bar. If necessary, replace the defective lubricating quill (3) (see
paragraph 2 and paragraph 4).
