Oil grade
(B) (A) (C)
(B) (A) (C)
(B) (A)
(A) : Ambient temperature recommended for general use of hydraulic system and
components.
(B) : Ambient temperature guide for machine operation from a hydraulic oil viewpoint only,
it does not guarantee the completion machine for other conditions like engine starting
performance. In this range a warming-up period is needed to obtain proper performance.
(C) : Ambient temperature range to operate machine under special conditions, not a
recommendation for general use conditions.
Additional recommendation for severe cold areas
A field solution for severe cold condition of ambient temperature between -40°C and
+20°C.
- Type : Anti-wear type hydraulic oil
- Viscosity characteristic
Viscosity index : More than 130
Kinematic Viscosity : Less than 5,000cSt at -40°C, More than 5.6cSt at +90°C
NOTE!
This value is approximately equivalent to ISO Viscosity grade #22.
NOTE!
It is minimum theoretical recommendation without the guarantee of machine condition.
