9 Recommended working medium
:
⑴
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.
