Important Safety Instructions

WARNING: Failure to follow these safety instructions may result in fire, explosion, electric shock, or other serious injury or death.

Always ensure proper grounding of the pump before operation to prevent static discharge and potential ignition of flammable liquids.
Do not use this pump for transferring highly volatile or corrosive liquids not specified in the compatible fluids list.
Ensure all connections are secure and leak-free before operating the pump.
Operate the pump in a well-ventilated area, away from open flames, sparks, or other ignition sources.
Do not operate the pump for more than 30 minutes continuously to prevent overheating. Allow adequate cooling time between uses.
Wear appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling fuel and operating the pump.
Keep children and unauthorized personnel away from the operating area.
In case of spills, immediately clean up the spilled fluid according to local regulations.

Setup and Assembly

Attach Fittings: Securely attach the provided hose adaptors/fittings to the inlet and outlet ports of the pump. Use the sealing tape on the threads to ensure a tight, leak-proof connection.
Connect Hoses: Connect your desired inlet and outlet hoses (not included) to the attached fittings using the hose clamps. Ensure clamps are tightened firmly to prevent leaks.
Install Handle: If not pre-installed, attach the portable handle to the pump using the provided screws. (Refer to the "Tips" section in the product features for handle and screw location).
Power Connection: Connect the red alligator clip to the positive (+) terminal of a 12V DC battery and the black alligator clip to the negative (-) terminal.
Positioning: Place the pump on a stable, level surface. Ensure the inlet hose is fully submerged in the fluid source and the outlet hose is directed into the receiving container.

Operating the Fuel Pump

The TOPWAY fuel pump features a convenient two-way switch for controlling the direction of fluid transfer.

Select Pumping Direction:
- Set the switch to 'I' for forward pumping (fluid moves in the direction indicated by the arrow on the pump body).
- Set the switch to 'R' for reverse pumping (fluid moves in the opposite direction).
- Set the switch to 'O' to turn the pump OFF.
Initiate Transfer: Once connections are secure and the desired direction is selected, switch the pump ON. The pump is self-priming, but ensuring the inlet hose is fully submerged will aid in faster priming.
Monitor Transfer: Observe the fluid transfer process. Do not leave the pump unattended during operation.
Stop Transfer: Once the transfer is complete or the fluid source is depleted, switch the pump OFF ('O' position).
Clear Hoses (Optional): For convenience and to prevent spills, you can use the reverse pumping function ('R' position) to clear any remaining fluid from the hoses back into the source or receiving container.

This video provides visual instructions on how to operate the fuel pump, including selecting the pumping direction using the two-way switch and demonstrating the fluid transfer process.

Care and Maintenance

Cleaning: After each use, especially when transferring different types of fluids, it is recommended to flush the pump with a small amount of clean, compatible fluid to prevent residue buildup.
Storage: Store the pump in a clean, dry place away from direct sunlight and extreme temperatures. Ensure all hoses are drained and disconnected.
Filter Inspection: Regularly inspect the inlet filter for any debris or blockages. Clean or replace the filter as needed to maintain optimal pump performance.
Connection Check: Periodically check all hose connections and fittings for tightness and signs of wear or damage. Replace any worn components immediately.

Troubleshooting Guide

Problem	Possible Cause	Solution
Pump does not start	No power connection	Check battery connections (positive to red, negative to black) and ensure battery has sufficient charge.
Pump runs but no fluid transfers	Inlet hose not submerged or air leak	Ensure inlet hose is fully submerged. Check all hose connections for air leaks and tighten clamps.
Slow fluid transfer	Clogged filter or kinked hose	Inspect and clean the inlet filter. Check hoses for kinks or obstructions.
Fluid leaks from connections	Loose fittings or damaged sealing tape	Tighten all hose clamps and fittings. Reapply sealing tape if necessary.
Pump overheats and shuts off	Continuous operation beyond duty cycle	Allow the pump to cool down for at least 30 minutes before resuming operation. Avoid continuous use beyond the recommended duty cycle.
