Setup
Follow these steps to assemble your PCP hand pump and perform an initial pressure test.
- Assemble Components: Install the foot pedal onto the base of the pump, secure the handle to the top piston rod, and attach the outlet hose to the pump's connection port. Ensure all connections are tightened securely.
- Initial Unloaded Pumping: Before connecting to any device, run the pump unloaded for approximately 100 cycles. This helps to lubricate internal components and ensure smooth operation.
- Attach Test Plug and Relief Valve: Connect the pressure test plug to the end of the hose. If your model includes a pressure relief valve, ensure it is properly attached and closed.
- Perform Pressure Test: Pump several cycles and observe the pressure gauge. Check all connections for any air leaks. If leaks are detected, tighten connections or inspect O-rings for damage. The pump should hold pressure without significant drop.

Operating Instructions
Follow these steps for safe and efficient inflation:
- Connect to Device: Select the appropriate adapter for your device (e.g., air rifle, tire, ball, kayak) and securely connect it to the pump's hose. Then, connect the adapter to the device you wish to inflate.
- Positioning: Place the pump on a stable, flat surface. Stand with your feet on the foot pedal to stabilize the pump.
- Pumping Technique:
- Pull the handle up to about 90% of its full extension. Keep your arms locked and lean slightly forward.
- Squat down, using your full body weight to keep your arms locked, and press the handle down completely.
- Pull up with your back straight, maintain arm position, and repeat the motion.
- Monitor Pressure: Continuously monitor the pressure gauge during inflation. Stop pumping once the desired pressure is reached, ensuring not to exceed the maximum pressure rating of your device or the pump.
- Disconnect: Once inflation is complete, slowly open the pressure relief valve (if applicable) to release any residual pressure in the hose. Then, carefully disconnect the hose from your device.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump.
- Oil-Water Separator Filter: The pump features an integrated oil-water separator. Regularly check and replace the filter element to ensure dry air delivery and prevent moisture from entering your device. Replacement filter cotton pads are included in the accessory kit.
- Lubrication: Periodically lubricate the pump's piston and O-rings with silicone oil to maintain smooth operation and prevent wear. Refer to the accessory kit for appropriate lubricant if provided.
- Cleaning: Keep the exterior of the pump clean and free from dirt and debris. Use a damp cloth for cleaning. Do not use harsh chemicals.
- Storage: Store the pump in a clean, dry environment, away from direct sunlight and extreme temperatures.

Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty Pumping / Low Pressure Output | Worn or dry O-rings/seals; Clogged filter; Air leak in connections. | Lubricate O-rings; Replace worn O-rings/seals; Replace filter element; Check and tighten all connections. |
| Air Leakage | Loose connections; Damaged O-rings/seals; Faulty check valve. | Tighten all hose and adapter connections; Inspect and replace damaged O-rings; Contact VEVOR support if check valve is suspected. |
| Moisture in Air Output | Saturated oil-water separator filter. | Replace the filter element in the oil-water separator. |
| Gauge Not Reading Correctly | Damaged gauge; Air trapped in gauge line. | Perform a pressure test to verify gauge accuracy; If consistently inaccurate, the gauge may need replacement. Contact VEVOR support. |
