Operating Recommendations

• Avoid simultaneous short-term elevated speed and short-term elevated pressure.
• Recommended filtration: ISO cleanliness class 20/16; nominal filtration — 25 microns or higher.
• It is recommended to use high-quality mineral hydraulic oil HLP (DIN 51524) or HM (ISO 6743/4).
• Recommended minimum kinematic oil viscosity — 13 mm²/s (≈70 SUS) at 50°C.
• Recommended maximum operating system temperature — 82°C (≈180°F).
• To ensure a long service life of the hydraulic motor, before full load, fill the system with working fluid and allow the unit to operate at medium load and speed for 10–15 minutes.
