Frequently Asked Questions
We highly recommend using N46 hydraulic oil. The viscosity should be between 15-68 cst and must be clean and free of impurities to ensure optimal pump performance.
The first oil change should be performed after the initial 100 hours of operation. Following this, the oil should be replaced every 3000 running hours.
S3 duty refers to intermittent operation. For this unit, it means the motor should run for a maximum of 30 seconds followed by a rest period of 270 seconds to prevent overheating.
No, for proper lubrication and oil suction, the power unit must be mounted horizontally.
The double-action valve allows the power unit to push and pull the hydraulic cylinder actively in both directions, providing much more control than a single-acting gravity-return system.
The assembly includes an overflow valve to prevent over-pressurization and an oil absorption filter screen to protect the internal gear pump from debris.
