Dump Trailer Hydraulics: Care and Troubleshooting

If your dump box won't raise, it's usually the battery, the fluid or the remote.

Box won't raise

  • Battery: A weak battery is the #1 cause. Charge it fully and test again. A solar charging kit keeps it topped off.
  • Fluid: With the box fully down, check the reservoir. Top off with AW32 hydraulic fluid.
  • Remote: Inspect the remote's cord and plug for damage.
  • Overload: Make sure the load is within the trailer's rated payload.

Safety

Never work under a raised box without the safety prop engaged. Always dump on level ground.

Annual care

Grease the hinge and pivot points, inspect hoses for chafing, and change the fluid every 2 years.
