- Overview
Hand-Pump Backup Version
Introduction
Designed for small tipping trailers, this power unit integrates a high-pressure gear pump, DC motor, multifunctional manifold, valves and tank. A hand pump with a displacement of 8 cc per stroke provides backup lifting in the event of a power failure. Lowering is activated by the solenoid valve.

Remote-Control Version
Introduction
This power unit integrates a high-pressure gear pump, DC motor, multifunctional manifold, valves and tank in a power-up, gravity-down circuit. Starting the motor raises the equipment. Lowering is activated by the solenoid valve, with speed regulated by the pressure-compensated flow control valve. This series is suitable for automotive equipment, garden machinery and other material-handling applications.

Precautions
- S3 intermittent duty: 30 seconds on and 270 seconds off. Continuous operation is not permitted.
- Clean all hydraulic components, cylinders, hoses and fittings before installing the power unit.
- Use clean hydraulic oil free of impurities, with a viscosity of 15-68 cSt. N46 hydraulic oil is recommended.
- Mount the power unit horizontally.
- Check the oil level in the tank after the initial operation of the power unit.
- Change the hydraulic oil after the first 100 operating hours and every 3,000 hours thereafter.
