Introduction to Manual Hydraulic Retriever Tool
The Manual Hydraulic Retriever Tool is a specially designed device for extracting components in a variety of industrial applications by controlling the hydraulic mechanism. It is manually operated, allowing precise manipulation of fluid pressure and safe and efficient retrieval of parts. In situations where precise handling and positioning are critical, the tool is highly valued for its reliability and ease of use.
Manual Hydraulic Pump
Hydraulic pumps usually do not require any special maintenance. However, when the pump is to be stored for a period of time after a series of operations, the following instructions should be followed:
Visual examination.
Perform a visual inspection of pumps and hydraulic hoses to ensure all components are in good condition. Pay special attention to the following points:
Hydraulic hose. There should be no obvious damage to the surface of the hydraulic hose.
Quick coupling. They should be easy to connect and disconnect, and should not have any external or internal damage.
Pressure gauge. The pressure gauge should be intact and respond immediately to an increase in pressure.
Replace the oil in the reservoir.
Hydraulic oil may be contaminated by moisture or other liquids/gases in the line and should be replaced; This prevents potential internal corrosion of the pump that may occur later.
The following steps should be performed:
- Completely empty the oil tank.
- Fill the tank with new hydraulic oil.
- Connect the hydraulic hose to the pump.
- Unscrew the quick-connect couplings from the free end of the hydraulic hose.
- Pump 10-20 strokes in both “RETRIEVE” and “INSTALL” modes, making sure that the new hydraulic oil flows through both hydraulic hoses.
Reconnect the quick connection connector to the hydraulic hose.
If further maintenance or repair (such as replacing seals) is required, refer to the “Spare Parts List” that comes with the pump. For any further maintenance or spare parts, contact the pump manufacturer directly.
