5. Operating Instructions
Follow these steps for safe and effective liquid transfer:
- Prepare Containers: Place the source container (e.g., fuel can) on a stable, level surface. Position the receiving container (e.g., vehicle fuel tank) below the source container if possible, to aid gravity flow once pumping starts.
- Insert Intake: Insert the rigid intake tube of the pump into the source liquid, ensuring the intake end is fully submerged.
- Position Outlet Hose: Place the free end of the transfer hose into the receiving container. Use the integrated locking clip to secure the hose to the receiving container's opening for hands-free operation.
- Start Pumping: Locate the power switch on the pump handle. Press the switch to the 'ON' position to begin liquid transfer.
- Monitor Transfer: Observe the liquid transfer process. Do not leave the pump unattended during operation.
- Stop Pumping: Once the desired amount of liquid has been transferred or the source container is empty, press the power switch to the 'OFF' position.
- Remove Pump: Carefully remove the transfer hose from the receiving container, then remove the intake tube from the source container. Allow any residual liquid to drain.


6. Maintenance
6.1 Cleaning
- After each use, especially when transferring fuels, it is recommended to run a small amount of clean, compatible liquid (e.g., water for water-based liquids, or a small amount of the same fuel for fuel transfer) through the pump to flush out residues.
- Wipe the exterior of the pump with a damp cloth. Do not submerge the pump in water.
6.2 Storage
- Store the pump in a cool, dry place, away from direct sunlight and extreme temperatures.
- Ensure the pump is clean and dry before storage.
- Remove batteries if the pump will not be used for an extended period to prevent leakage and corrosion.
