Frequently Asked Questions
We recommend using N46 hydraulic oil. Ensure the oil viscosity is between 15-68 cst and is completely free of impurities to prevent pump damage.
The first oil change should be performed after the first 100 hours of operation. Subsequent changes should be conducted every 3000 hours of running time.
S3 refers to intermittent periodic duty. For these units, it means the motor should be active for a maximum of 30 seconds followed by a 270-second rest period to avoid overheating.
No, for optimal performance and to ensure the gear pump is properly lubricated and primed, the power unit must be mounted horizontally.
The double-action solenoid valve allows the unit to control the extension and retraction of a hydraulic cylinder automatically via electrical signals.
It prevents metallic particles and contaminants from entering the pump and valves, significantly reducing the risk of internal leakage and component failure.
