1.9 Recommended working medium:
(1) Hydraulic oil:
A. When it is normally loaded, we advise:
Hydraulic oil: LHPISOVG46, in accordance with standard DIN51524T.2, the average sustained temperature should between 40 degrees to 60 degrees.
B. When it is over loaded, we advise:
Hydraulic oil: LHPISOVG68, in accordance with standard DIN51524T.2, the average sustained temperature is above 60 degrees.
C. When it is lightly loaded with low temperature, we advise:
Hydraulic oil: HLPISOVG32, in accordance with standard DIN51524T.2, the average sustained temperature is below 60 degrees.
D. At the occasion with variable loading, we advise:
All the working conditions mentioned above can use the hydraulic oil LHPISOVG46 in accordance with standard DIN51524T.2 for replacement. The viscidity of this lubricant is very high (mostly used hydraulic oil).
If it is difficult to buy hydraulic oil, SAE20W/20 engine oil can be used to substitute HLP68 hydraulic oil.
(2)Gear oil:
Hyperbola gear oil 85W-90(GL-5)
(3) Lubricating grease:
Lithium grease of type 3
All kinds of depleted hydraulic oil, gear oil and grease will pollute the environment. For this reason, recycle the replaced working medium or treat according to local pertinent regulations
