"The right tool in good condition makes all the difference between a smooth repair and a frustrating delay."
A jack that won’t lift can bring work to a standstill, creating unnecessary stress and delays. If your equipment is failing, there’s usually a simple reason behind it. From low hydraulic fluid to trapped air in the system, small issues can lead to major inconveniences. Understanding what’s wrong can save time and effort while ensuring safety when lifting heavy loads like truck car jack.
1. Check the Hydraulic Fluid Level
Low or contaminated hydraulic fluid is one of the most common reasons a jack won’t lift. If the fluid is too low, the jack won’t generate enough pressure. Old or dirty fluid can cause internal blockages, preventing proper lifting.
Solution:
● Locate the fluid reservoir and check the level.
● If low, refill with high-quality hydraulic oil.
● Replace old fluid if it appears dark or has debris.
2. Remove Trapped Air from the System
Air pockets in the hydraulic system prevent proper lifting. This happens when air enters the system due to low fluid levels or improper storage.
Solution:
● Fully lower the jack.
● Open the release valve.
● Pump the handle several times to remove air bubbles.
● Close the valve and test the lift.
3. Inspect for Leaks and Damaged Seals
Leaks reduce pressure, making the jack weak or completely non-functional. Check for fluid around the base, handle, and seals.
Solution:
● Tighten loose fittings.
● Replace worn-out seals to restore pressure.
● Use a leak-resistant hydraulic fluid to prevent further issues.
4. Ensure the Release Valve is Properly Closed
A partially open release valve prevents the jack from building pressure. This simple issue is often overlooked.
Solution:
● Locate the release valve and turn it clockwise to ensure it’s fully closed.
● Test the jack by lifting a small load before using it on heavier objects.
5. Inspect for Dirt and Debris in the Pump System
Dirt buildup inside the hydraulic system can block fluid flow, causing lifting issues.
Solution:
● Wipe down external components regularly.
● Flush the hydraulic system with fresh oil if contamination is detected.
● Store the jack in a clean, dry place when not in use.
6. Verify the Weight Limit
Exceeding the jack’s capacity can strain the system and prevent proper lifting.
Solution:
● Check the weight of the load.
● Use a jack with the appropriate lifting capacity.
● Avoid unnecessary force, which can damage internal components.
7. Maintain Proper Storage and Handling
Incorrect storage can lead to air leaks, fluid contamination, and premature wear, reducing the jack’s performance over time.
Solution:
● Store the jack in an upright position to prevent leaks.
● Keep it in a dry, dust-free environment to avoid contamination.
● Periodically check for rust or corrosion and apply protective coatings as needed.
Final Thoughts: Keep Your Equipment in Top Condition
