Key features include high power performance, quick lifting capabilities, and a durable construction designed for longevity. The unit comes pre-assembled, requiring only the addition of hydraulic oil and connection of power and hoses for operation.
2. Safety Instructions
Read and understand all safety warnings and instructions before installing, operating, or maintaining this hydraulic pump. Failure to follow these instructions may result in serious injury or property damage.
- Electrical Safety: Ensure the power supply matches the pump's voltage (DC 12V). Disconnect power before performing any maintenance or installation. Use appropriate wiring and circuit protection.
- Hydraulic Fluid: Use only recommended hydraulic fluid. Avoid skin contact and inhalation of vapors. Dispose of used fluid responsibly.
- Pressure Hazards: Hydraulic systems operate under high pressure. Never attempt to disconnect hoses or fittings while the system is pressurized. Always relieve pressure before servicing.
- Installation: Mount the pump securely on a stable surface. Ensure all connections are tight and leak-free.
- Operation: Do not exceed the pump's maximum pressure or flow rate. Keep hands and clothing clear of moving parts.
- Maintenance: Regularly inspect the pump for wear, damage, or leaks. Replace worn components immediately.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, gloves, and protective clothing, when working with hydraulic systems.

4. Setup Instructions
The hydraulic pump is delivered pre-assembled. Follow these steps for initial setup:
- Mounting: Securely mount the hydraulic power unit to a stable, flat surface on your equipment (e.g., dump trailer, lift gate). Ensure it is protected from excessive vibration and environmental elements.
- Add Hydraulic Oil:
- Locate the oil refill port (usually a red cap).
- Remove the cap and carefully fill the reservoir with the recommended hydraulic oil. Refer to your equipment's manual for specific oil type. Do not overfill.
- Replace the oil refill cap securely.
- Connect Hydraulic Lines:
- Connect the hydraulic line from your equipment to the oil tube connector (M18×1.5) on the pump.
- Use the provided SAE#6 adapter if necessary for compatibility.
- Ensure all connections are tight to prevent leaks.
- Connect Power Supply:
- Connect the positive (+) terminal of the pump to the positive (+) terminal of a 12V DC battery (e.g., 12V 200A battery).
- Connect the negative (-) terminal of the pump to the negative (-) terminal of the battery.
- Ensure connections are secure and free from corrosion.
- Verify correct polarity to prevent damage to the motor.
- Remote Control Connection: Plug the remote control switch into its designated port on the pump unit.
5. Operating Instructions
This single-acting hydraulic pump is designed for lifting applications, with gravity lowering.
- Pre-Operation Check: Before each use, inspect the hydraulic system for any visible leaks, damaged hoses, or loose connections. Ensure the hydraulic fluid level is adequate.
- Lifting Operation:
- To lift your equipment (e.g., dump bed, scissor lift), press and hold the "UP" button on the remote control switch.
- The pump will activate, and the hydraulic cylinder will extend, raising the equipment.
- Release the "UP" button once the desired height is reached.
- Lowering Operation:
- To lower your equipment, press and hold the "DOWN" button on the remote control switch.
- This action typically opens a valve, allowing gravity to lower the equipment. The pump motor does not activate during lowering.
- Release the "DOWN" button when the equipment is fully lowered or at the desired position.
- Emergency Stop: In case of an emergency, release all buttons on the remote control. If necessary, disconnect the power supply to the pump.

6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your hydraulic pump.
- Hydraulic Fluid Check: Check the hydraulic fluid level regularly (e.g., monthly or before heavy use). Top up if necessary with the recommended fluid.
- Fluid Replacement: Replace hydraulic fluid according to your equipment manufacturer's recommendations or at least annually, depending on usage.
- Filter Inspection: If your system includes a filter, inspect and clean or replace it as recommended to prevent contamination.
- Leak Inspection: Periodically inspect all hoses, fittings, and seals for leaks. Tighten connections or replace components as needed. The pump is designed with a robust seal to minimize leaks.
- Electrical Connections: Check battery terminals and wiring for corrosion or loose connections. Clean and tighten as required.
- General Cleaning: Keep the pump unit clean and free from dirt, debris, and moisture.
7. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not operate. | No power supply, loose electrical connections, faulty remote switch, low battery. | Check battery charge and connections. Inspect remote switch wiring. Ensure power is connected. |
| Slow or weak lifting. | Low hydraulic fluid level, air in the system, clogged filter, worn pump components, low battery voltage. | Check and refill hydraulic fluid. Bleed air from the system. Inspect/replace filter. Check battery voltage. |
| Hydraulic fluid leaks. | Loose fittings, damaged hoses, worn seals. | Tighten all connections. Inspect hoses and seals; replace if damaged. |
| Equipment does not lower. | Faulty lowering valve, obstruction. | Check the lowering valve for proper function. Inspect for any physical obstructions. |
| Pump motor runs but no lift. | Low fluid, air in system, relief valve stuck open, internal pump failure. | Check fluid level. Bleed air. Inspect relief valve. Contact qualified technician if internal failure is suspected. |
If you encounter problems not listed here or if the suggested solutions do not resolve the issue, contact VEVOR customer support or a qualified hydraulic technician.
