| MECHANICAL SYMPTOMS |
CAUSES |
SOLUTIONS |
| Bridge does not open automatically onto truck floor as platform is being raised. |
Adjustable Height Bridge Wheel is not adjusted properly. |
Loosen the Wing Bolt on the Adjustable Bridge Wheel and raise the wheel channel so that it gently guides the Truck Bridge open as the platform is raised. A properly adjust ed Bridge Wheel should not touch the underside of the opened Truck Bridge after it is level with the truck floor because the Bridge Wheel is not designed to support loads. It simply guides the bridge gently above truck floor or dock height. |
| Raising or lowering SL platform causes noticeable squeaking sounds |
Ball bushings on lifting arms need grease. |
Grease thoroughly according to lubrication chart. |
| Bridge folding into and out of truck squeaks. |
Bridge hinge pins and/or bridge wheels need grease. |
Grease hinge pins and bridge wheels liberally. |
| Rolling resistance of SL wheels makes movement increasingly difficult. |
Swivel wheels need greasing or replacement if damaged. Rigid Wheels have been damaged. |
Grease or replace wheels. Rebuild ground surface with smooth level concrete, and/or use SL multiple vehicle special running gear options. For larger models (SL-8000 and up), use an optional tow bar and tugger. |
| Stabilization jacks do not operate easily. |
Jacks need greasing or are damaged. |
Grease both on the jack threads and directly into the grease fitting, and replace bent or damaged parts. |
