Understanding the Need to Bleed a Pallet Truck

A pallet truck, a vital tool in many industries, relies on a hydraulic system to lift and lower heavy loads. Over time, air can accumulate in this system, leading to decreased performance, slow lifting, and even complete failure. Bleeding the pallet truck removes these air bubbles, ensuring optimal performance.

Steps to Bleed a Pallet Truck

Materials Needed:

• Hydraulic fluid compatible with your pallet truck

Procedure:

1. Check the Fluid Level:

   • Locate the hydraulic fluid reservoir.
   • Ensure the fluid level is adequate. Top up if necessary.

2. Pump the Handle:

   • With the pallet truck unloaded, pump the handle repeatedly. This action forces air bubbles out of the system.
   • Continue pumping until the forks lift smoothly and the pump handle becomes harder to operate.

3. Check for Leaks:

   • Inspect the hydraulic hoses and fittings for any leaks.
   • If you find a leak, repair it before proceeding.

4. Bleed the Valve (Optional):

   • For some models, there might be a specific bleeder valve. Consult your pallet truck's manual for instructions.
   • Use a wrench to loosen the bleeder valve slightly, allowing air to escape. Tighten the valve once the fluid flows steadily.

Troubleshooting Common Issues

• Slow Lifting or Lowering: Air trapped in the system can cause this. Repeat the bleeding process.
• Fork Tilt: A misaligned hydraulic system or air bubbles can cause this. Check for leaks and bleed the system.
• Hydraulic Fluid Leaks: Repair any leaks promptly to prevent fluid loss and potential damage.

Maintenance Tips for Optimal Performance

• Regular Inspection: Check the fluid level, hoses, and fittings for damage or wear.
• Lubrication: Lubricate moving parts to ensure smooth operation.
• Proper Storage: Store the pallet truck in a dry, clean environment to prevent corrosion and damage.
• Professional Servicing: Schedule regular professional servicing to identify and address potential issues.

By following these steps and tips, you can effectively bleed your pallet truck and maintain its optimal performance. Remember to always consult your pallet truck's specific manual for detailed instructions and safety precautions.
