Check the structure of each jack stand for signs of fatigue or cracks. Structural problems can cause sudden failure, so you must spot them early.

Look for smooth areas on the metal, which can show where a crack started and grew slowly.
Find rough areas, especially with a “cup and cone” shape, which often mark the final fracture zone.
Inspect welds and joints for any separation or deformation.

If you see any of these signs, do not use the jack stand until you repair or replace it.

Fasteners and Pins

Examine all fasteners and pins for security and wear. Missing or loose parts can make the jack stand unsafe.

Ensure all lock pins, safety chains, handles, casters, and handrails are present. Replace any missing components.
Inspect the frame of the jack for damage and repair if needed.
Check bolts and pins on towbars. Tighten any loose bolts and replace missing pins before use.
If possible, perform a proof load test to confirm that the jack stands can support the rated weight.

Safety Reminder: Never skip this step. A missing pin or loose bolt can cause the jack stand to fail under load.

By following these inspection steps, you help ensure the jack stands on your arrow board sign trailer remain safe and reliable. Regular checks catch problems early and keep your equipment in good working order.

Jack Stand Maintenance

Cleaning and Lubrication

Routine cleaning and lubrication keep your jack stands working smoothly and extend their lifespan. You should remove old, caked grease from all moving parts to prevent damage to the chrome plating. Use a solvent like brake cleaner to flush out the shafts. Once a year, clean the inner jack tube and apply a light grease or silicone spray lubricant. Fill the lower cup and surrounding gears with Redline CV2 grease for optimal performance.

Remove old grease to protect metal surfaces.
Flush shafts with brake cleaner for deep cleaning.
Clean the inner tube annually and lubricate it with silicone spray.
Apply Redline CV2 grease to gears and the lower cup.

You can choose the right lubricant for your jack stands by considering their benefits:
