Overview

This document provides the user manual for the VEVOR Electric Motor Hydraulic Pump, models GYB-630B, GYB-630B II, GYB-700A, and GYB-700A II. VEVOR emphasizes providing tools at competitive prices, often using expressions like "Save Half" or "Half Price" to indicate estimated savings compared to major top brands. Users are advised to verify actual savings when placing an order.

The manual begins with a strong warning: "READ THESE INSTRUCTIONS CAREFULLY BEFORE" followed by a section on "SPECIFICATIONS."

Function Description:

The VEVOR Electric Motor Hydraulic Pump is designed to provide high hydraulic pressure for various applications. It serves as a power source for hydraulic tools, converting electrical energy into hydraulic power. The pump is intended for industrial use, providing the necessary oil flow and pressure to operate compatible hydraulic equipment. The different models offer variations in control mechanisms (hand switch or foot switch) and valve types (single-acting manual, single-acting solenoid, double-acting manual, double-acting solenoid), catering to diverse operational needs. The pump's primary function is to generate and maintain hydraulic pressure and flow to drive hydraulic cylinders or other hydraulic actuators.

Usage Features:

The manual emphasizes safety and proper operation. Users are instructed to "SAVE THIS MANUAL" for future reference, including safety warnings, precautions, assembly instructions, operating and maintenance procedures, parts list, and diagrams. It is crucial to keep the invoice with the manual.

Before use, the hydraulic pipe must be connected to the hydraulic pump outlet using the quick fitting connector. Prior to operating the pump unit, users must check the oil tank to ensure sufficient hydraulic oil, with the level higher than the oil-window. The air-out screw must be opened before operation. The oil pressure should be regularly inspected with the gauge.

General safety warnings and precautions are provided, covering a wide range of topics:

  • Work Area: Keep clean, well-lighted, dry, and free from flammable gases or liquids.
  • Children: Keep children away from the work area and tools.
  • Storage: Store idle equipment in a dry, locked location out of reach of children.
  • Tool Usage: Do not force the tool; use the right tool for the job. Do not modify the tool.
  • Personal Safety: Dress properly (no loose clothing or jewelry), wear protective, non-conductive clothes, non-skid footwear, and hair covering. Use ANSI-approved eye and ear protection (safety goggles, full face shield, dust mask/respirator). Maintain proper footing and balance; do not overreach.
  • Tool Maintenance: Maintain tools with care, keep them sharp and clean, follow lubrication and changing instructions. Inspect cords periodically.
  • Electrical Safety: Disconnect power when not in use. Remove adjusting keys and wrenches before plugging in. Guard against electric shock by avoiding body contact with grounded surfaces. Use the proper size and type of extension cord (0-12 amps, 16 AWG for up to 50 feet; larger wires for longer cords; "WA" rated for outdoor use).
  • Operation Awareness: Avoid unintentional starting. Stay alert and use common sense; do not operate when tired or under the influence of alcohol or drugs.
  • Damaged Parts: Check for damaged parts before use; ensure proper operation and alignment. Any damaged part should be repaired or replaced by a qualified technician. Do not use the tool if the switch does not turn On and Off properly.
  • Pacemakers: Be aware that electrical equipment near a heart pacemaker could cause interference.
  • Common Sense: The manual stresses that common sense and caution are factors that must be supplied by the operator.

Maintenance Features:

Regular maintenance is critical for the longevity and safe operation of the hydraulic pump. Key maintenance instructions include:

  • Hydraulic Oil:
    • Change the hydraulic oil every 18 months.
    • Filter the oil before changing.
    • #15-#32 hydraulic oil is recommended.
    • Add oil or change hydraulic oil if oil flow is insufficient.
  • Bearing Parts: Replace and lubricate bearing parts every 18 months.
  • Oil Hose:
    • Keep replacing the oil hose once any damage or aging.
    • The standard rated pressure of the oil hose is 105MPa.
    • Inspect the oil hose at 87.5MPa (recommended).
  • Fittings: Before each use, check all fittings for tightness.
  • Motor Cooling: Allow the motor to cool down after extended use. Stop working if the motor becomes excessively hot to protect the pump system.
  • Operating Temperature: Handle the pump at 10-50°C.
  • Professional Service: For safety, service and maintenance should be performed regularly by a qualified technician. The manufacturer and/or distributor expressly state that all repairs and parts replacements should be undertaken by certified and licensed technicians, not by the buyer.

Troubleshooting (Common Faults and Solutions):

The manual provides a basic troubleshooting guide:

  • Motor Abnormal:
    • Reason: Electric power
    • Solution: Check the power
  • Pressure Abnormal:
    • Reason: Oil leaking
    • Solution: Make inspection and replace new O-rings
  • Oil flow insufficient:
    • Reason: Oil
    • Solution: Add oil or change hydraulic oil

The document concludes with an FCC compliance statement, indicating that the device complies with Part 15 of the FCC Rules, and operation is subject to two conditions: (1) it may not cause harmful interference, and (2) it must accept any interference received, including interference that may cause undesired operation.
