Pickup Liftgate Maintenance Guide | Maxon C2 Series

What to Inspect Before Every Shift

When your job depends on a pickup lift gate, even minor issues can lead to big delays. That’s why Maxon outlines a series of daily safety and functionality checks for its C2 model, designed to help you spot potential problems before they turn into downtime. This article compiles those factory-recommended tasks into a clear, practical guide.

Whether your Maxon C2 pickup liftgate is mounted to a Ford, Chevy, Dodge, or Toyota, these pre-use checks help ensure your gate stays ready for action day after day.

Before starting, park the vehicle on level ground and set the parking brake. Do not operate the liftgate if any issue is found during inspection.

Battery and Housing

A reliable pickup truck liftgate starts with solid battery performance.

Maxon recommends verifying that the truck’s batteries are fully charged and that the terminals are clean and tightly connected. The main frame housing should be intact, with no signs of damage or leaking hydraulic fluid around its enclosure.

Control and Platform Functionality

The operator should inspect the liftgate control switches—both standard and optional—to confirm they are secure and undamaged.

Next, unfold the platform and flipover to ensure they release properly from their latches and move freely to the ground without sticking or binding. This basic movement check ensures the liftgate pickup is safe to use before loading begins.

Hydraulic System

Check the hydraulic cylinders for visible fluid leaks, which can affect both lift performance and safety.

Then follow the routing of the hydraulic hoses from the cylinders to the main frame, verifying that connections are secure, and there are no signs of cracking, chafing, or leaking.

Surface Cleanliness and Decals

Surfaces on the main frame housing, platform, and flipover should be clean and free from oil, corrosion, or debris. This ensures safe footing for operators and stable load handling.

All decals—including warnings and instructions—must be legible, clean, and in place. If any are missing or unreadable, replacements should be requested from the manufacturer to fix your Maxon Liftgate immediately.

Platform Latching and Structural Checks

A safely stowed platform is essential when your pickup truck lift gate is not in use.

Confirm that the platform is latched securely on both sides, with undamaged chains connected properly. Visually inspect all structural components including the main frame, columns, lift arms, parallel arms, as well as bolts and pins for cracks, bending, or missing hardware.  

Platform Surface and Chain Tension

Check the platform and flipover for cracks, holes, or deformations, especially in load-bearing areas.

If using a platform with a flipover ramp, ensure all hinged sections function smoothly. With the platform raised to bed height, manually test the left and right chains for even tightness—inconsistent chain tension can lead to uneven loading and wear.

Functional Cycle Test (No Load)

Before putting the gate into service, run it through one full cycle without a load.

Raise it to truck bed height and then lower it to the ground, listening for abnormal noises and watching for jerky or uneven movement.

Maxon specifies that any side-to-side movement of the platform should not exceed 1 inch, and performance should be smooth and stable throughout the cycle.

Conclusion

Preventative maintenance is the easiest way to extend the life of your lift gate and reduce unexpected service calls. By following this Maxon-recommended checklist before every use, operators can avoid unsafe conditions, preserve performance, and keep deliveries running smoothly. If your pickup’s liftgate isn’t operating exactly as expected, don’t force it—pause and inspect. A few minutes each day can prevent costly downtime.
