Operating Instructions

The Zefal Z Cross AL mini pump is designed for easy and efficient tire inflation. It is compatible with Wood, French (Presta), and Car (Schrader) valves. Follow these steps to inflate your tire:

Prepare the Valve:
- Presta Valve: Unscrew the small nut at the top of the valve stem. Press down briefly on the valve stem to release a small amount of air, ensuring it is unseated.
- Schrader Valve: No special preparation needed, just remove the valve cap.
- Wood Valve: Ensure the valve is clear and ready for connection.
Attach the Pump Head: Firmly push the pump head onto the tire valve. For Presta valves, ensure it is pushed down far enough to engage the valve. For Schrader valves, push down until it seals.
Secure the Connection: If your pump head has a lever, flip it to the locked position to secure the pump head to the valve. This prevents air leakage during inflation.
Inflate the Tire: Hold the pump body firmly and push and pull the handle in a steady, continuous motion to pump air into the tire. Continue pumping until the desired tire pressure is reached (up to 7 bar / 101.5 PSI). Refer to your tire's sidewall for recommended pressure.
Remove the Pump: Once inflated, flip the lever back to the unlocked position (if applicable) and quickly pull the pump head straight off the valve.
Close the Valve:
- Presta Valve: Screw the small nut back down firmly to seal the valve.
- Schrader Valve: Replace the valve cap.

Maintenance

Proper maintenance will ensure the longevity and optimal performance of your Zefal Z Cross AL mini pump.

Cleaning: Wipe down the pump body with a damp cloth after use, especially if it has been exposed to dirt or mud. Avoid using harsh chemicals or abrasive cleaners.
Lubrication: Periodically apply a small amount of silicone-based lubricant to the pump's piston shaft to ensure smooth operation and prevent wear. Do not over-lubricate.
Storage: Store the pump in a clean, dry place away from direct sunlight and extreme temperatures. When not in use, keep it attached to your bike or in a gear bag to protect it.
Valve Head Inspection: Regularly inspect the rubber gasket inside the pump head for signs of wear or damage. A worn gasket can lead to air leaks during inflation. Replace if necessary.

If you encounter issues while using your Zefal Z Cross AL mini pump, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Pump not inflating tire / Air leaking from valve connection	Pump head not fully seated on valve. Lever not locked (if applicable). Worn or damaged rubber gasket in pump head.
