General rules for the hydraulic motor use:
-
Working oil temperatures in the hydraulic system should be kept between +30°C and +60°C. The
anti-wear and lubrication properties of the oil are greatly reduced at higer temperatures.
-
The ambient temperature around the engine should be between -30°C and +90°C
-
Only use an oil containing antiwear additives ISO 46 or with a viscosity at normal operating
temperature of approx. 37 cSt, it should also have an adeguate viscosity index. Under no
circumsances should oil viscosity be outside the range of 22 cSt to 75 cSt.
-
Before starting the hydraulic system check oil level and firm mounting of all components.
-
Run the system unloaded for 10÷15 minutes to purge air from the circuit to prevent foaming and
deviation.
-
Check for leak, rectify and refill reservoir
-
Check oil level regularly and clean filters or replace them according to filter manufacturers advice
For maximum life from motor oil contamination shoul never exceed the 20/16 (see ISO 4406).
To ensure this level, return line filters should maintain 40 µm absolute or 25 µm nominal in open
circuit, 20 µm absolute and 10 µm nominal in closed circuit.
