How to Fix a Pallet Jack If It Won’t Lift Up

A pallet jack is an essential tool to move heavy loads in warehouses, stores, and factories. But what happens when your pallet jack won’t lift?

Don’t worry! You can now understand how to repair pallet jack step by step. Whether you need to troubleshoot the hydraulic system or repair a simple issue, these tips will help fix pallet jack.

Common Problems When a Pallet Jack Won’t Lift

A pallet jack not lifting is problematic. There are plenty of pallet jack use, and having a faulty one can hinder it. This issue can further escalate and make room for several other problems like:

1. Low Hydraulic Oil: The hydraulic system may lack enough fluid to lift the load.
2. Air in the Hydraulic System: Air bubbles can block the proper flow of hydraulic fluid.
3. Worn Seals: Damaged or worn seals can cause hydraulic leaks.
4. Broken Handle or Release Valve: A faulty handle or stuck release valve can stop the lifting mechanism.
5. Damaged Pump Piston: If the piston is cracked or broken, it won’t generate enough pressure.

Tools You’ll Need for Pallet Jack Repair

To fix pallet jack, you need the necessary tools:

• Screwdrivers
• Wrenches
• Hydraulic oil
• Seal kit (if needed)
• Cleaning material such as towels or cloth

These tools will help you repair a pallet jack efficiently.

Step-by-Step Guide: How To Repair Pallet Jack

Step 1: Check the Hydraulic Oil Level

Low hydraulic oil is one of the common reasons for a faulty pallet jack. Follow these steps:

1. Locate the oil reservoir on your pallet jack.
2. Remove the cap and inspect the oil level.
3. If it’s low, top it off with the recommended hydraulic oil.

Make sure not to overfill, as this can cause leaks.

Step 2: Remove Air from the Hydraulic System

If your pallet jack not lifting, then try adding oil. There might be air trapped in the hydraulic system.

Bleeding the air out can fix the problem.

1. Lower the forks completely.
2. Pump the handle several times without a load.
3. Repeat this process until the lifting action becomes smooth.

This step is important to make sure that the flow of hydraulic fluid is as per requirement.

Step 3: Check the Seals

Damaged seals can lead to hydraulic fluid leaks. It can loosen the lifting power of the pallet jack. Here’s how you can make sure that the seal is intact.

1. Tilt the pallet jack to access the hydraulic cylinder.
2. Inspect the seals for wear or cracks.
3. Look out for damaged seals and replace them if required.

Properly functioning seals are a must to maintain hydraulic pressure.

Step 4: Release Valve

The release valve controls will help lower the forks. If it’s stuck or broken, the pallet jack won’t lift.

Here’s how to fix it:

1. Check the valve for dirt or debris that may block its function.
2. Clean it properly with a cloth or cleaning solution.
3. If the issue still persists, consider replacing it.

A functional release valve ensures smooth lifting and lowering.

Step 5: Take a look at Pump Piston

The pump piston is a key part of the lifting mechanism. If it’s damaged, the pallet jack won’t lift properly.

To inspect it:

1. Remove the pump to access the piston.
2. Look for cracks or signs of wear.
3. Replace the piston if it’s damaged.

With a new piston you’ll be able to ensure the right amount of pressure needed for lifting.

Step 6: Test the Pallet Jack

After completing the repairs, test your pallet jack. Load it with a small weight and pump the handle. If it lifts smoothly, your pallet jack is ready for use.

Maintenance Tips to Avoid Pallet Jack Repair

Preventive maintenance can keep your electric pallet lifter in an ideal working condition and reduce the need for repairs.

Follow these tips:

• Check Hydraulic Oil Regularly: Ensure the oil level is adequate and free of contaminants.
• Clean Moving Parts: Dirt and debris can cause wear and tear. Clean the wheels and forks often.
• Lubricate Joints: Apply grease to the moving parts to reduce friction.
• Inspect for Leaks: Regularly check for hydraulic fluid leaks and address them promptly.
• Store in a Dry Place: Moisture can turn into rust real quick, so always store your pallet jack in a dry area.

When to Seek Professional Help?

If the above steps don’t fix the issue, it might be time to consult a professional technician. Complex problems, such as a damaged hydraulic cylinder or extensive internal wear, require expert repair services.
