This image displays the complete oil pump assembly, featuring a chrome-plated pump body with a black handle at the top, a sturdy black base, and a U-shaped copper tube accessory designed for drawing oil from containers. The inlet and outlet fittings are visible near the base.
4. Eto
- Ṣetan Agbegbe Iṣẹ: Ensure a clean, stable, and well-ventilated environment.
- Connect to Oil Source:
- For open oil containers: Attach the U-shaped copper tube to the inlet port (1/2" flare) and place the other end into the oil container.
- For sealed oil containers or specific applications: Connect appropriate tubing or adapters to the inlet port.
- Sopọ si Eto: Attach a suitable refrigeration hose from the pump's outlet port (3/8" flare) to the system's service port. Adapters (e.g., 3/8" to 1/4" flare) may be required depending on the system's port size. Ensure all connections are tight to prevent leaks.
- Fi Pump naa pamọ (ti o ba jẹ dandan): Before connecting to the system, a few strokes may be needed to draw oil into the pump cylinder if it's empty.

5.1. Adding Oil to a System
- Ensure the pump is properly set up and connected as described in Section 4.
- Open the valve on the system's service port to allow oil to enter.
- Operate the pump handle with smooth, steady strokes. Each full stroke delivers approximately 3.8 oz (112.38 ml) of oil.
- Monitor the amount of oil being added to ensure the correct charge is achieved.
- Once the desired amount of oil has been transferred, close the system's service port valve.
- Disconnect the refrigeration hose from the system and then from the pump.
5.2. Removing Oil from a System (Reverse Suction)
The pump can also be used to remove oil from a compressor or system, though this method may not fully drain all oil.
- Connect the pump's outlet port to the system's oil drain or service port.
- Connect a waste oil container to the pump's inlet port.
- Operate the pump handle. The pump's design allows for a degree of reverse suction to pull oil from the system into the waste container.
- Dispose of waste oil according to local regulations.
6. Itọju
- Ninu: After each use, wipe down the exterior of the pump with a clean cloth. If different types of oil are used, it is recommended to flush the pump with a compatible cleaning agent or the new oil type to prevent cross-contamination.
- Ibi ipamọ: Store the pump in a clean, dry, and dust-free environment. Ensure all ports are capped or covered to prevent contaminants from entering.
- Awọn ibamu Periodically inspect all fittings and connections for wear or damage. Replace any worn O-rings or seals as needed to maintain a leak-free operation.

| Isoro | Owun to le Fa | Ojutu |
|---|---|---|
| Pump not drawing oil. | Inlet port not submerged in oil; air leak in inlet connection; pump not primed. | Ensure inlet tube is fully in oil; check and tighten all inlet connections; prime the pump by cycling the handle a few times. |
| Oil leaking from connections. | Loose connections; damaged O-rings or seals; incorrect fitting type. | Tighten all connections; inspect and replace damaged O-rings/seals; ensure correct flare fittings are used. |
| Difficulty pumping. | High system pressure; clogged lines; internal pump issue. | Ensure system pressure is within pump's operating limits (max 250 PSI); check for obstructions in lines; if problem persists, contact Yellow Jacket support. |
