Oil refilling of the Hydrocheck
Suitable oil quality: Hydraulic oil with a viscosity of e.g 32 cSt at +40º C (+104 F) and a high viscosity
index e.g. 345. Recommended oil: Castrol, Hyspin AWH-M 32 acc. to ISO VG32.
Oil quantity (filled): Ca 6,3 cl (2.22 fl.oz. (UK), 2.13 fl.oz. (US))
Oil refilling equipment: Part. no. 043J400426
WARNING!
1. When filling oil the feed spindle should be fully extended so that the hydrocheck piston rod
is fully retracted.
2. If, for some reason, the green level indicator, see Fig. 15. Pos. 1, is fully visible when filling oil, it should
be depressed manually.
3. Connect an oil injector to the oil filling nipple, see Fig. 15. Pos. 2, and fill oil until the green indicator pin
is nearly completely extended again. Note! Discontinue filling just before the pin is completely extended
to avoid excessive pressure in the system.
4. Whenever the hydrocheck has been disassembled or if air has entered the oil system, The system must
be bled when filling oil. The hydrocheck must then be turned so that its piston rod is facing upwards as
oil is being filled and the system is bled using the screw shown in, see Fig. 15. Pos. 3.
Note! The piston
rod must be completely depressed while filling oil. Begin filling with the bleeding screw open and when
the oil stream is air-free, tighten the screw. Then fill with oil until the indicator pin Pos. 1 is extended.
