Common Faults & Troubleshooting Guide
Ramps Not Lifting / Dropping Smoothly
Causes: Low hydraulic fluid, air in the lines, or damaged springs.
Solutions: Check hydraulic fluid level; bleed air from the lines; replace worn springs.
Uneven Tire Wear
Causes: Misaligned axles, worn suspension bushings, or incorrect tire pressure.
Solutions: Align axles every 6 months; replace worn bushings; maintain correct tire pressure.
Air Brake Leaks
Causes: Cracked air hoses, loose fittings, or a faulty air tank.
Solutions: Inspect hoses for damage; tighten loose connections; replace the air tank if leaking.
Frame Rust or Corrosion
Causes: Scratched paint finish, exposure to salt or moisture.
Solutions: Touch up paint chips; wash the trailer regularly; apply anti-rust spray to exposed metal.
